Dynamic Racing's new Heads and Cam package is on! So, after talking with Matt at Dynamic Racing and a few trips down to his shop to look at the BEAUTIFUL heads, we finally got to line up his test car and my new 07 to actually see the differences! As you will see by the video the H/C jeep instantly pulls my stock Jeep hard! What I was most amazed by was that the H/C was just finished the night before and the ECU had NO learning miles! I think with a tank of gas through it there will be even more of a difference! Also, his Jeep doesn't have ANY exhaust work!! I think that leaves a ton more power on the table!! At only $1999 for the package, so much more power, and like stock drivability, I cannot imagine NOT doing this mod! Heck I spent $1200 just for my Mopar exhaust...yikes. I will install the exhaust this weekend and we are also doing some dyno tests and track runs before next week!!

Here are the facts:

Ekool's Silver 06:

Dub Air CAI
GSM Fan/Torque Mod
Dynamic Racing's Heads
Comp Stage 2 Cam


Wicked's Black 07:

GSM CAI
GSM Fan/Torque Mod

There is NO tuning or ECU changes, just a direct bolt on of Dynamic Racing's H/C! The Jeep idles just like stock!!

Sorry guy's I had to take the video's down :( We live in small town NM and I had my attorney advise me to take down the video's because of the extreme risk to us and that we could serve a night with bubba on a twin bed...yikes! I know this might sound stupid to you guy's in big cities, but when you represent a third of the Cherokee SRT8 population in the whole state the word get's around. Especially when it's an insainely fast Jeep :D


Needless to say after these races on our test track I am next inline for my Dynamic Racing H/C Package!!

wow!! nice vid. how much do they cost?that's a HUGE difference! :eek:

Dynamic Racing is selling the H/C package for $1999!!!!!

Oh yeah and there were 2 people in both cars. We wanted to make it as even as possible :)

Honestly, I would expect more from ported heads and a cam. I'm not saying it was the case, but it really didn't look like the Jeep w/ camera was getting on it for a good portion of the races either; in some there was a large difference but in others not much at all, per the mods anyway. Any chance the H/C Jeep will hit a real drag strip for some numbers?

Wow, nice run! I had a friend bragging about how much more power a LS2 in the TBSS can make from a Cam and I may have to get this upgrade to make sure he still knows his place in the SUV food chain.

Hurry up with the dyno, we need to see some numbers!

you got to be kidding right? Do you have any idea how much HP it takes to push a 4800 lb truck to a 5-6 car lead in a 50 to 110mph race?

The 07 jeep was not jetting on it? lol the owner/driver of the 07 posted the thread. He was on it.

We are going to the track in Roswell on Sat. Ekool has run plenty of base line stock runs there with his best being 13.9@100 (most 14.1@99). (remember this track is at 3600ft) So we have a good base line.

Out ported 5.7L heads, cam, headers, exhaust gained 93 WHEEL hp on a 06 charger

Thanks and congrats.

Yes I do. Again, it's hard to tell if the camera jeep is really getting on it--most of the time it appears to me that he isn't--it's simply hard to tell if there's a legitimate 5-6 car difference from 50-110 as you say. In runs 4, 5, and 6 the camera vehicle obviously gets off the throttle first, and it's hard to tell exactly where. You'll also notice that in every shot of the camera cars tach, it's at ~3300rpm or less.

I look forward to seeing your results. Was the same Jeep with H/C used for the baseline?

Great, but there obviously wasn't a 93whp gain on the Jeep. Speaking of, are you going to slap it on the dyno, and did you prior to the H/C swap? Don't get me wrong. If you end up with significant gains at the strip I'll be the first to congratulate you, it's just going to take more than a video like this.

We did the install, takes 2 days.

Doing heads/cam on these motors is not hard at all.

The Sale price $1999 pkg is just heads/cam. you can get the needed gaskets at the dealer, or I can sell you a full Gasket and bolt kit for $199

i assume the head and cam package produces no nasty side effects like CEL, rough idle, etc?

what is the installation cost on something like that on the 6.1L motor?

The Jeep has a VERY slight more lump to the idle, but it's hard to even tell. And not a Single CEL.

We are running a sale on the install too. $1200 for SRT-8's. (labor)

Thats amazing. Damnit ekool, wash your Jeep!!! haha. Amazing how much of a jump it gets form a dig. The 40 mph roll was a lot less jump but it continually gained lengths. Looks like money well spent!

that’s the way races work, it's easier to gain speed from 0 mph then it if from 50 mph... Races are won and lost in the 1st 60ft...

The truck is a totally different monster then stock, I cant wait to see how it does at the track.

whens it hitting the track? Dyno?

Yes same Jepp, Ekool's as far as I know he does not own 2.... lol

I dont think thats going to happen at a track thats at 3600ft. Ekool's BEST time in the Jeep Stock at that track so far is a 13.9@100mph and that was only 1 pass. The Rest are all 14.1's@99mph

Do you have a handheld weather station, or another way of recording the pertinent weather data so we can calculate DA?

Thanks

KOOKS Headers and Hi Flow Cats + B&B Catback gave me a 1.8 60' and a 13.00 flat @ 104.57 MPH, and the sound is second to none. With better air and a better truck prep before a race ill be in the 12's next time. I have never gone above a 1.9 60' and that was when I brake stalled it to 2500 RPM's which ill never do again it cost me off the line 2/10th's. Cool video btw.

Hey guys, just saw this thread. I was going to hold off on posting until we had some dyno numbers and track numbers to post, but no big deal, those will come shortly.

We plan to visit Area 51 Dragway located in Roswell, NM. It is listed on the NHRA track list and has an official correction factor at their homepage. We do not have a weather station but we will be there with some friends that do so I will get the readings from them and post them after we make some runs.

Our track is small and usually not prepped very well so mid 1.9 60's were the best I could manage on the previous trip. We'll see if we can improve on that this time. As Matt mentioned, my best pass was a 13.9 and these were night runs. We plan to run during the day so temperatures will be higher this time for sure.

As far as my driving impressions on the street, it really is a different beast. It has much better throttle response and a much better torque curve. It drives like stock until you hit 30% throttle or more and you notice alot more power. The most impressive performance increase is definetly off the line. The car is down right stick from a stop, it gets squirrely on bad roads on the 1-2 shift and you have an urge to lift because you arent sure if your are going to go sideways :)

Have not had any CEL's or anything like that.. Hopefully I can post more once we get the track and dyno runs done... and I'll wash the damn bugger ;)

Oh, I wanted to add an update to this. One thing I always wished for was a higher stall converter in the Jeep... it just felt like it could really pick up some acceleration and get into the powerband much quicker if the stall was 1000RPM higher or so. However, with the improved torque curve and increased power, the stall flash seems to have increased and there is no more need. No complaints in that department anymore.

So now, my only complaint is needing to get some lowering springs for this damn jeep ;)

and keeping it clean...congrats man! So you can brake them loose on the 1-2 shift? Thats a monster!! Have fun

Congrats on the results, I can't wait until the track results. I hope you get some vid of that too. There is a converter for sale now ,but its stall isnt far from stock, 2600. http://www.moparsupercenter.com/
Can most anyone who is somewhat mechanically inclined remove/install these heads? Is there any obvious physical evendence that would get the warranty voided?

Yes, depends on the road. We have a main road through town here called White Sands Boulevard and it is pretty slick, that road it really gets squirrely on :)

and keeping it clean...congrats man! So you can brake them loose on the 1-2 shift? Thats a monster!! Have fun

Truly doing heads/cam on these hemi's is in the world of doing heads/cam on a late model car is quite simple. MUCH easier then doing heads/cam on a F-body.

From the out side there is no way to tell that the heads/cam are installed. And if you dont do headers/exhaust you cant even really tell by the sound of the Exhaust. I think a dealer would be VERY hard pressed to tell that Ekool's jeep was modded at all other then the CAI.

Still has not thrown a single code.

With track/dyno verification, I really like the idea of this kit. Its the sleeper kit for the sleeper. AND, no friggin injectors shooting dinojuice into a DRY intake manifold...Something I cannot and will not do/try/attempt...

Stroke-Good thought with the station to keep the runs fair and level. To many times the mods doctors do the high/low altitute track game to show results.

"VERY slight more" Ok I give up on what that means :)

Anyway, in the video, it had a nice sound to it at the end.

Get them kits ready, I'll probably own one this spring after the winter goes away.

Well, for those of us unfortunate to live and race at high level, as long as people recognize the fact that altitude DOES make a difference, thats all I ask for. When others are running 13.5 stock times vs. my 13.9 stock time and the correction factor puts me at 13.5/13.6 -- i tend to think its pretty accurate :)

Especially when the 60's are similar.. I mean, theres not much to driving this thing down the track, its all in the launch.. after that, your just a pedestrian on for the ride really.

Now, my 10 second 6-speed Supra was entirely a different story :)

very impressive.

Does DR port/polish the intake too?

well guys you asked for it, we made the trek down to the AWD dyno in El Paso today with both jeeps.

I knew people were going to ask about the MPG thing so on the way there both jeeps got up to 90 mph and set the cruise and reset the MPG trip comp. The stock heads/cam 07 got 15.5 mpg, the Heads/cam 06 got 15.2mph at 90mph.

Now about the Dyno, it’s a AWD Mustang Dyno.

1st up was the 07 base line (GSM CAI, GSM TQ/fan mod)

Dyno set to record the pull from 2500rpm to 6000rpm (found there was no point in going past 6000 rpm on the stock heads/cam at 6000 rpm the power it already starting to level off and even drop slightly)

PK AWHP 346
PK AWTQ 341

That was the best of 3 pulls

Next up was Ekools 06 (DR- heads/ cam, Dub CAI, GSM TQ/Fan mod)

1st pull Dyno still set to record from 2500rpm to 6000rpm

PK AWHP 419
PK AWTQ 413

Power was still going up when the dyno stopped recording at 6000 rpm. So we decided to do the next pull to 6100rpm, and hot lapped right back to another pull no cool down.

PK AWHP 421
PK AWTQ 417

The gain in HP from the extra gain in HP from the 100rpm was no big surprise, but the gain of 4 ft’ lb of TQ down low surprised me, I guess the thing liked the heat.

I wanted to try pulling it higher but Ekool the owner of the jeep was happy with a 75 AWHP gain! and did not want to push it any more up in the RPM, but there would for sure be more power going up some more in RPM seeing how the power is still going up at the end of the pull.

Now the best part, at 2500rpm where the pull recording starts the stock heads/cam truck is making ~285 ft/lb of TQ, the Heads/cam car is making 350!!! So this power gain is not just up top!!


The Dyno shop is going to be E-mailing us the dyno charts so we can post them most likely tomorrow. If they don’t I’ll just take a picture of these printed dyno charts and post the picture.

Talk about sleeper power! No headers, stock Exhaust and 75 MORE Wheel HP! This truck drives and for the most part sounds like a stock truck. I can’t wait to see what Headers/Exhaust and a tune will do.

Solid info, thanks! Question where did TQ peak stock and modified? I can't wait to see the difference in area under the curve between the two. I would think that with a full exhaust and some basic tuning 450+whp wouldn't be out of the question. Nice work.

There is ALOT to be said for correctly ported heads were low and mid lift #'s are looked at and not just high lift #'s. We spend over 200 hrs of R&D on and off the flow bench to get exactly what we were looking for. And the best peek # we could get at a lift # that no cams for these cars have is NOT what we were looking for, unlike allot of shops I have seen

I have no idea what you just said?

Well in short, if the biggest cam you can get for these motors (and the biggest you can run with stock pistons) is ~.550 lift. What good would it be for us to port our heads so we get the best flow #'s at .600" or .700" lift, when the valve will never see that? And wile doing that making the lo-lift #'s suffer from decreased port velocity.

Just Like power under the curve is what makes a car fast, the best flow across the full lift range of the cam will make for the faster/more fun to drive car. Not just the best peek #.

Also No porting was done AT ALL to the intake Manifold, it's just a stock 6.1L intake Manifold

^^^ Thanks for clarifying.

Yes the intake is on the to-do list. But we did not want to do it yet, we wanted this test to be simply heads/cam and no other differences between the 2 jeeps.

the heads would not make a difference at all for smog, as for the cam I don’t think it has a CARB sticker (that most likely means Comp has never even tried to CARB test it). But in this case on this jeep even the stock cats were not changed. Now will it pass smog in CA? I truly have no idea, living in NM I have never smoged a car in my life.

Do we ship the stock heads and wait; or is it an exchange?
Details please.

The camera man would only go over to the Dash AFTER the races were OVER and the driver had let off and the tranny had up-shifted, and was slowing down .Look at the tach you can tell the tranny has already up-shifted from letting off.

If you even listen you the vid you can here he already let off.

Haha...After being beat by that distance to 100mph you would have throwin in the towel too! Oh, incase you didn't know, these cars have a 5 speed auto and when you let off the tranny doesn't like to continue to run at redline...it up shifts ;)

excellent gains, i look forward to some strip times.

Check out what the 5.7 Hemis are running, 12.97 ET big mph? Smaller cam profile that a stock 6.1? Think about it? MHO Gene

Nice mod. Bang for the buck is attractive. HP gain is impressive. But here in NY, the emissions police wont ceritfy your car at inspection time if it does not pass the emissions test at the annual inspection. Emissions test results are faxed directly to the state capital - I'm not making that up. NY has the most strict emissions tests behind CA. The cam upgrade looks good, but I'm hessitant due to the unkown emissions issue. I know this is a far fetched suggestion, but ekool and/or fastmatt - have you thought about having ekool get inspected in CA? If it passes inspection there, then it will pass anywhere. Remember I'm in NY, so I dont know how far ekool is from CA. Just a suggestion.... Anyway nice mod & numbers.

fastmatt - What type of power gain does the head produce with out the cam?

Matt, glad to see your making great heads/cams on the SRT-8 Platform as well.
I can tell all you guys, Dynamic is a great company and has made awesome progress on the 3S (3000GT/Stealth). I dont doubt any claims made by him. He has always backed up his claims with numbers in his many stealths.

Keep up the good work. I plan to get a JGC SRT-8 next year with my friends corporate discount ;)

Do you have a mods list? I dont think there are many 5.7's running 12.9 on just H/C... I'll find this posting, yes it is happening. These 5.7 hemis with stock 6.1 heads lost big performance, reason ports are wrong shapped, sluggish flow, better used on bigger displacement engines. (bigger than 6.1L, 6.4 or bigger) This is second hand information and one such vehicle is in Arizona? Wrong approach is a P&P 6.1 heads, at least three good head porters have examined these heads and commented. I'll wait to see what the new heads, local shop is engineering, will do on a stock 6.1. I'll be looking at these, in person, soon? Bigger isn't always Better. I have proof of this. Not an opinion of mine but from several savy head porters and engine builders. I'll believe them not Vendors comments only! Gene

your post has totally lost me... This is the best I could make heads or tales of it.

If you are saying that putting 6.1L heads on a 5.7L is NOT a good Idea, I Totally agree with you. Sticking with porting the 5.7L heads on the 5.7L cars is the way to go.

As for porting the 6.1L heads for a 6.1L motor, there are huge gains to be had if the porting is done correctly, we have already proved that.

But I have already seen some badly botched port jobs from other shops on 6.1L heads that truly did slow cars down.

So far maybe 2 tenths in the 1/4 mile or less for big dollars. I witnessed these big mods at the 06 Nats, not too impressing when compared to pure stocker cars! PCM mods made the big gains with stock heads and headers! Still true today. Playing the dumb interpretations of my post doesn't prove anything to me or others. Comparing big gains mainly do the air density not parts proves nothing to me. The SRT Engineers did a pretty good job designing this engine and any improvements are very hard to achieve so far. Lets do a side by side comparison between the big HP gainers, same day, same track, as this will tell more of the truth to what works or not. Stockers run better in cold air too! Gene

You have not seen any of our heads/cam cars run at the track yet have you?

I agree with you that there are alot of ported 6.1L heads out there that preform VERY porly. And I know why.

But lets take a look at Mine.

75 AWHP & 76 AWTQ gain, and 65 AWTQ gain at 2500rpm, And a vid posted of the heads/cam Jeep totally destroying a stock heads/cam Jeep from a stop, and from a roll. Seems quite a bit faster, and more powerful to me. ( and these 2 jeeps belongs to the Board Admin, and another board member, not to me)

As soon as tracks start opening up again you will be seeing more track times, and our heads/cam cars are going to be destroying any stock times that’s for shore.

O ya and PS at the 2006 Mod Face off in CA, a Dynamic Racing heads/cam(ported 5.7L heads, and the smallest comp cam we offer) 5.7L 300C beat EVERY other N/A hemi car at the 1/4 mile track in CA same day. Including all the N/A 6.1L cars. (the 300C was also not my car, sold him the heads/cam mail order)

If there is one thing I know how to do it's make cars fast.


And PS maybe YOU should re-read your last post because you clearly mention 5.7L motors in it, now I think you are saying you did not. So maybe you should think about proof reading your posts to make shore thy say what you mean before posting them. I'm still having a hard time figuring out if you are talking about putting 6.1L heads on a 5.7L or not.

Can someone PM me the link to the videos mentioned in earlier post? It seems to have disappeared.

Thanks,

Do you have a mods list? I dont think there are many 5.7's running 12.9 on just H/C... Look at the LX site, the 5.7 is listed there with current mods and time slips! My point, reason a better head design for the 6.1 hemi too! We'll see real soon? Gene

You have not seen any of our heads/cam cars run at the track yet have you?

I agree with you that there are alot of ported 6.1L heads out there that preform VERY porly. And I know why.

But lets take a look at Mine.

75 AWHP & 76 AWTQ gain, and 65 AWTQ gain at 2500rpm, And a vid posted of the heads/cam Jeep totally destroying a stock heads/cam Jeep from a stop, and from a roll. Seems quite a bit faster, and more powerful to me. ( and these 2 jeeps belongs to the Board Admin, and another board member, not to me)

As soon as tracks start opening up again you will be seeing more track times, and our heads/cam cars are going to be destroying any stock times that’s for shore.

O ya and PS at the 2006 Mod Face off in CA, a Dynamic Racing heads/cam(ported 5.7L heads, and the smallest comp cam we offer) 5.7L 300C beat EVERY other N/A hemi car at the 1/4 mile track in CA same day. Including all the N/A 6.1L cars. (the 300C was also not my car, sold him the heads/cam mail order)

If there is one thing I know how to do it's make cars fast.


And PS maybe YOU should re-read your last post because you clearly mention 5.7L motors in it, now I think you are saying you did not. So maybe you should think about proof reading your posts to make shore thy say what you mean before posting them. I'm still having a hard time figuring out if you are talking about putting 6.1L heads on a 5.7L or not. And I'm shore I'm not the only one that cant clearly make out what you are talking about in you posts.
. My posts are very clear, the 6.1 heads were looked at by two of the best head porters in the Nation. Installing them on the 5.7 block only shows the velocity problem, building HP at the top of the rpm range, worthless in building Speed and Performance. Their Comments not Mine but experienced engine builders, one won the Hemi shoot out, the other is building a killer 6.1 engine now. These people are Veterans in Performance Engines, like a GTO that makes 750 rwhp with only 8# of boost! Claudes 12.820 ET, stock, shows the potential without spending big dollars, just good choices to find what works. No big tube headers, HF Cats will ever be on my JGC, current SCs, No NO2 either! My Point Exactly and Reasons. Crystal Clear! Spend your money wisely. Compared to the muscle cars of old the new ones all use good technology and people all want to improve on them but finds little gains without spending big dollars, check out the magazine articles written on doing mods and the little gains after? The "PROOF IS IN THE PUDDING" my motto! Lats see side by side races not some theories, sound tunings, seat of the pants feelings, and making vendors rich. I went through this with my Buick Grand National that ran 10.80 ET at 121.45 mph and throwing away loads of money to find out what didn't work. I'm not a Novice either to building a performance vehicle, the SRT8 is a different nut to crack, harder for sure. Can it make big performance, maybe, how much? Time will tell as a lot of new parts are coming to the market soon? I do wish all the best and good racing. Gene

You enjoy the heck out of the ol' question mark, don't ya :D

ok That part I got correct and I clearly replied to you with this.



If you are saying that putting 6.1L heads on a 5.7L is NOT a good Idea, I Totally agree with you. Sticking with porting the 5.7L heads on the 5.7L cars is the way to go.




Though the point is really moot on this board seeing how SRT-8 Jeeps have a 6.1L hemi NOT a 5.7L



like a GTO that makes 750 rwhp with only 8# of boost!


ok and I have built 750+ AWHP 3.0L motors on a stock 3.0L short block, not a 7L stroker LS2. And ran 9.73@151mph on street tires. so?



The "PROOF IS IN THE PUDDING" my motto! Lats see side by side races not some theories, sound tunings, seat of the pants feelings

Mine too, that why we posted proofe, From the races VS a stock heads/cam Jeep, to the Dyno #'s, and soon track times.

Just like my heads/cam pkg for the 5.7L Hemi's, That 300C ran head to head at the 06 modface off with Stock and modded 5.7L and 6.1L LX cars same track, same day and ran the best times of any of the N/A cars. The closest computers heads/cam 5.7L car was 3/10th slower.




and making vendors rich. I went through this with my Buick Grand National that ran 10.80 ET at 121.45 mph and throwing away loads of money to find out what didn't work.

lol $1999 to gain 75 AWHP and 76 AWTQ? lets see thats what $700 more then a Mopar cat back that gaines nothing?



I'm not a Novice either to building a performance vehicle, the SRT8 is a different nut to crack, harder for sure.

That’s why we spent so much time on R&D BEFOR releasing out heads/cam pkg.



I do wish all the best and good racing. Gene

Thanks, I will. You too

Look at the LX site, the 5.7 is listed there with current mods and time slips! Gene


are you talking about this 300c?

that car has MY (Dynamic Racing) heads/cam on it!

Gene,

Can you provide a direct link to the 5.7 in question? You mentioned previously that a car with only heads/cam on a 5.7 was running 12.9 -- and I would like to see that. Every 5.7 that has run 12's or better that I've seen has more mods then just H/C but I might have missed something.

Let me know, thanks.
