Ok, This place is one hour + away from me so the Beast was HOT. We dumped it right on then started our pulls. The temps here were very high, 90 and high humidity.

If we cooled it down we would be over 500HP at the wheels!! :D

I am happy with it! Next is the track!

Where's the "DROOOOOOLING" smiley when you need it. I can't wait to see track times. (Run at 3am when it's cool out:D :D )


I have a question though, do our trucks really have that much driveline loss/rate? If FHP (stock) is 420hp and your baseline dyno was 322hp, that's a tad over 23%

?? Just curious at what everyone has been seeing??

TOO MUCH, I would say just under 15k

The tune is actually good. The A/F was almost on mark, slightly lean from 4k on, I will have to run some good fuel.

ASM is in discussions with DiabloSport. I might be the first to head down to get the custom tune, we will see. They are a few hours away!

The only AWD dyno here is at a company that I was told NOT to go to.

I also wanted to test on the same dyno that I pulled the first one at, for a good comparison.

The #'s should not change much either way, Unless with the T-case unplugged there are PCM issues, holding some power back.

Really nice Ride FAST, I'm itching to pull the FI trigger on my jeep as we speak. I am waiting for the procharger unit to come out though. I'm also very interested in DiabloSport's offerings once they're available down in DelRay.

Do you mind if i ask you what the ASM kit runs, and did you have it professionally installed? If so, what shop did it and how much did they charge you. I am a floridian as well, wouldn't mind having a shop do it that has the experience.

The kit cost 7600 Install should run 500-800 or so. And a good shop should be able to do it in a day. If you wanted I know I could do it in a day. Let me know. Your gun is kocked, now pull the trigger;)

DROOOOOOLING... Ha you shouldn't be with that vette you got there.. nice ride. Thanks, It's fun alright but with tow fuel (diesel on a mini-semi), sponsorship money slowly getting smaller and smaller every year (for our classes), race fuel, travel expenses and other expenses I am only driving that car a couple/few times a year as of now. Hence the GCSRT8. I wanted a fast daily driver, but with room.

(Think Corvette merged with a Tahoe:D :D )

I can do the conversion using software that I use for our race car. If you can get "actual" track temp, BP and RH (which is the easiest way for me), I can figure it out for you. There are also on-line calculators too.

I think with a longer cool down time, some ice on the intake and a richer fuel mix the TQ will go up... well so will the HP.

I think if we would have cooled it down for an hour or so and iced it we would have seen 500WHP. THat is putting some crazy #'s at the crank.

So far everyone that has taken a ride has said it felt like they were going to loose their stomach.;) ANd a few have compared it to the HULK ride at Universal. I am loving it! I think I will start charging admission.

It actually might be better in your case to leave the traction control on (when not at the track) since I bet the wheels spin like mad hamering the pedal from a dig.

I know an aftermarket tq might be stronger than oem but wouldnt that hurt the traction off the line, even with the tc on it might really pull back. otherwise he'll be doing 2 wheel donuts....wait you know,, i'd like to see a video of a blown gc doing 2 wheel donuts =)

A bit, It also dyes while shifting into 3rd or 4th(dont remember)

I have had best takeoff's with the factory TCM button pressed, which i did not do this time. I also had been driving around for an hour and saw a nice clear patch where i could get a good 1/4mile.

Next time I will do the limited TCM, and shift on my own. At the track I will but several bags of ice and let it sit for a few hours!!

Still factory TQverter. I do not plan on upgrading to a higher stall. I have been watching everyone that did that upgrade end up with lots of tire spin. I think a 2000k stall that is able to hold the power will be perfect.

Is it still pulling pretty hard at those speeds? Considering the amount of gear and wind it needs to overcome those are some nice numbers.

For context the stock C5 Z06 (405hp) was good for a 12.5 @ 116 and the car only weighs 3100lbs has far less wind resitance and is geared much more favorably for those speeds.

Congrats on your setup, it sounds like an absolute blast to drive!

what's up!
congrats on the great #'s.
i used to have more or less the same kit on my f-150. a trick i used to do at the track was to put dry ice on top of the aftercooler, if you hook up a relay to the pump you will be able to turn on the pump on while the truck is off. within about 10 min. you will see frost form on the aftercoolers' plumbing!
you might also want to put a small fan on the heat exchanger, you will get more consistant #'s.

Fast congrats on the numbers..........

Since I did not read ALL of the posts, I must ask this......

When did you add the Exhaust, Cam, B&G II and the other mods?

I ask because you do not have any Dyno #'s for all mods minus the S/C.

So my guestimate is that you just forked out 7600 buck for the S/C and only gained 60 -75 hp........ The other mentioned mods should have netted you around 80 hp..........

ASM claims that the 6.1L S/C adds 175 hp. I am not seeing it.

Also, the dyno is already at a corrected factor (this includes weather corrections). So, in actuallity you will probably only see another 20 hp gain from your heat soaked engine.....

The first dyno was with Exhaust and CAI
The second was with everything else.

I agree the numbers should be higher. The tune is for a stock S/C Jeep not one with my setup. So ASM will be retuning it.

I am not expecting any more then 20 or so HP after cooling it down. But that will put me into the 500+ I am good with that.

I will put it on a different dyno after I get the boost up and the fuel up also.
I am not sure if this dyno is calibrated well.

Like mentioned ASM made the kit for a Stock 6.1 Not one with all the BS i have. The Headers and DR heads and Cam are causing it to run way lean. ASM said the TQ # should be much higher with the right fuel mix!!

They are working with me everystep of the way trying to get the tuning down. My situation is very different then the protypes they had to work with while tuning. Plus these generic tunes are just that, with out a true dyno tune my jeep will always be choked out:( If i had the time I would drive down to diablo and camp out till they tune my jeep.

Wow Chris, get that tuning squared away ASAP. That A/F is going leaner than 13:1 over 6k rpm...VERY dangerous. I found out the hard way that I would rather it run rich at 11:1 then hovering around 13:1+. A thought to seriously consider is going with an adjustable Kenne Bell boost-a-pump to get some more fuel pump output.

A thought to seriously consider is going with an adjustable Kenne Bell boost-a-pump to get some more fuel pump output.

Another area that hasn't been talked about too much is injector capacity. What size injectors do we have? Could you be at maximum duty cycle for the injectors? Especially since they were not sourced for a SC'd application. Does the Dashhawk show injector duty cycle?

These are aftermarket injectors. ASM says they will support 700hp.
So I dont believe they are being maxed out YET!!

Throw a boost a pump on it. Adjustable from 1-50% more fuel pump output.

Do you guys have a return or returnless fuel system?

I have a returnless (for now), and with my boost-a-pump I have to command from the tune for more fuel. Volts do increase on my fuel pump from 13.25volts to 17.25 at 50%, but I still have to tell the computer to give me more fuel.

Chris knows all the secrets. He's waiting for a new tune then back to the dyno for air/fuel reading. Actually reading the air/fuel on the dyno can still be off. The best way is on the street with real time load. These dyno's/ companys make a ton of money and they may you think that reading the a/f on a dyno is perfect but it's not. I have a very good friend Herman which is the owner of Horse Power by Herman. We have done back to back tests between his dyno jet dyno compared to the a/f on street runs and it's always about a half point lean. My car and his car has been tuned on both the street and dyno and the cars run better on the real world street tune. It's amazing how he can play on the dyno to the car put out higher numbers. I'm not trying to say don't get your air fuel checked on the dyno I'm just saying it's far from perfect so if anything go on the rich side 11.0a/f.
This will help out on those hot sticy days and for that bad tank of gas that you could hit. BOOOOOOOOOOOOOM

That doesn't seem large enough for a SC'd 6.1 with all of your mods. The 03-04 Cobras came with 39s from the factory & the guys that did only a few mods were forced to upgrade to 55 lb/hr and even 65 lb/hr for the twin screw SCs. I was at 98% duty cycle(stock injectors) & I only had a smaller SC pulley, Billetflow TB, and very small dry shot of N2O.
If possible, you might try to datalog your injector duty cycle just for piece of mind.

Someone can tell us what injectors they are.They are most likely Ford Cobra 39# injectors. Here is a pic:http://i85.photobucket.com/albums/k57/ChallengerTurbo/Injectors.jpg

BTW, the Cobra injectors actually flow about 42lbs/hr(3 bar) and on the Hemi they flow about 49lbs/hr because we run a fuel pressure of 58psi(4 bar). I used to send those out with the turbo STS turbo kits on the Ram but now I send some better ones. The Cobra ones are not rated for 58psi plus at that pressure they are quite noisy and the rail needs to be raised about 3/8" to make them fit.

Those injectors are good to 560 crank hp with the following: .60 BSFC, 85% IDC and 58psi.

They look right, Turbo I might have to upgrade to an even larger injector. Do you still sell them?

I need a good KB boost a pump also... Anyone.

I do have larger injectors but with a piggyback you are limited to how large you can go and still be able to idle. How much bigger do you want to go on the injectors. I have some 612cc(58 lb/hr) at 4bar injectors that worked well with the PCM and piggyback. That vehicle has a 392(6.4L) and a GSM kit(Paxton 1500) running 12psi. He junked the aux injectors in place of 8 larger ones and switched piggybacks and has been running good ever since.

I can swing by Jim Bell's place and pick you up a Boost-a-pump if you want or you can call them directly.

Yea, it is more of a bandaid but it is a proven one that is adjustable.

If you can get me some pricing that would be great. I need injectors able to handle between 600-700 crank. And if can get the boost a pump at a good price then I will buy it from you. If it is a hassle then I will just get it on line...PM me if you can hook me up, I appreciate it.

The 612cc(58 lb/hr) injectors I mentioned earlier are good for 700 crank hp and if you get the boost-a-pump(BAP) your hp limits will go up with the same injectors.

You can get the BAP from Kenne Bell and I can pick it up and ship together with the injectors to save on shipping as I don't have any type of deal with them to buy/sell their products.

I will PM you.

Someone needs to install the ASM on a stock 6.1L and see what pans out! Stock meaning no B&G, heads or cam! This kit was supposedly prototyped on a 6.1L with heads ,268 cam(268 & hellfire,almost identical in specs),B&G II and headers---the piggy(unichip) should be dialed in a liitle better than it is. That being said, B&G's are know to run lean up top!--Get Dave to look at it!--Their are many N/A LX's having this trouble as well!!--- FYI. If the B&G is not the problem, then Jim S. @ ASM should be made aware of the issues.---- At $7,600 plus install for most, this should be a turn key--no fuss product, IMHO. Until other tuning options are available, if all else fails ,you might consider tuning it with an SMT-6 ---just a thought! GC

Have you got it bunged for an A/F monitor--would highly recommend it on F/I for now, till solid tuning options are there. I bet the A/F's are better up top with the OEM PCM-even with the piggy(since you don't need the B&G for cam issues,try running both ). Get an A/F monitor and let us know ? Good Luck GC.

Jim is overnighting me a new unichip monday we will see what that helps. I might put the stock PCM back in... wait, I need the higher idle.

The hellfire will idle @ 675rpm N/A,(hard to say F/I-larger injectors-would probably load up) it's lumpy. It's the stalling thats a PITA(like trying to stop a concrete truck with no steering). The OEM will learn (though not as quick as a B&G), gotta let it idle for 15-30 minutes or so. Take it thru a several decels from 30-40 mph down, don,t make any sudden stops in the meantime, till she learns closed to open loops & vice versa.---I didn't have the patience required, character flaw I guess, HA ! Maybe the new unichip will help--I hope it does!! Gotta represent us Jeep guys in FL. :D GC
