Did someone say 426? It's already been done for almost a month...

Representing and on behalf of Indy Heads, Power Ported Performance is proud to re-announce via the web in conjunction with Indy Heads, our modern Mopar Stroker Kit line for the 5.7L and 6.1L engines. As many saw at the Mopar Nationals in Columbus, OH this last weekend, we debuted our Modern Mopar Stroker Kit lines for the 5.7L and the 6.1L engines. I.e., the 392cu from the 5.7L and the 426cu from the 6.1L engine blocks.

The 426cu is making incredible power and even more incredible torque and these number are currently without modifying the ignition at all. Straight power!

Initial numbers are producing 560HP and 600lbs of Torque. Can you say Torque Monster!

I am sure there are many pictures floating around of the engines at the Mopar Nationals, but unfortunately, we were so busy, we didn't even get a chance to take any ourselves. Here is a picture of the engine on the Dyno.

And for those who want to see a little video of it... I only got a few seconds of it running. Still very cool!

This is the real deal. As you've seen before, we only talk about it when its done. Stay tuned for more details on the kits, pricing and availability over the next couple of weeks.



Best Regards and thank you for your continued interest,

Wow! The engine looks so cool.

Great Job guys :)

Keep it up, we are waiting for the details once you are ready?

Couple quick questions come to mind,

stock compression ratio retained?
will the stock cooling system work?

Cant wait guys!

i now know what will be sitting up front of the challenger that is goin to be in my driveway... to heck with mpg, and warrenty.... must have mo power. drooling on myself here

GREAT question! I will share this with the other forums as well.

The default will be at or very near to stock compression. There will be options to go lower for forced induction applications, at an added expense. The stock cooling system for the SRT's is over rated for the 6.1L and should function well, but desert heat testing of course has not been done and may require additional coolant configurations. I personally plan on upgrading my trani coolant and will likely add an additional engine oil coolant system as well.

What was the compression with the power numbers you got (560/600)?
Thanks

Hi THEMASH,

Thanks for asking. The compression for the dyno runs was right at stock numbers. Keep them coming...

What are the tuning options with this engine ?

INSAINE!!!!!!!:eek:

Thats an awsome motor. Will this motor be availible as a shortblock for the do it yourselfer's if you already have ported heads and stuff already. Also is the crank you guys run, is it a machined stock crank or is it an entirley new crank? Are all the internals forged? Any ruff ideas for pricing yet, I hope its under $10,000 for the motor unlike hennessy and their $18,000 392 stroker kit.

:D , I smell trouble

Nice TQ numbers... Looks like a 4.100 with a 4.065 Bore or a 4.125 Stroke alone with the stock 4.060 Bore. Did you guys ever experiment with the largest Bore possible on these blocks? I bet a big Bore, big valves setup would make more HP up top (6500-7000 RPM) and keep a wider powerband than the large Stroke setups. Just some food for thought :)

What size cam is in that thing? LSA?

These are a lot of great questions, and we are almost ready to share answers to many of your questions. Should be about a day or two. As for a few answers...

The motor will be available as a short block kit for those who already have ported Heads and Intakes. The crank is a custom Forged unit. It is new. Full kit details are forthcoming...

Stay tuned for more and thank you for your continued interest...

Awsome, I can't wait.

Can't wait for the pricing ...

Jeremy,

for us to plan on these kind of mods, we wish to know the expected time of availability of such upgrades and cost.. just ruff figures to give us a more of a general picture..

Thanks a lot

"Should be about a day or two" ?

Sorry about the delay in providing information. We made a decision to replace a weaker stock part that we originally recognized would be a weak link. Instead of allowing it to stay (it would last several years, but not for the longevity we are seeking in this build up) we decided to replace it with a Billet part.

This decision has caused a 2 week delay while the part is tooled. We should have numbers ready shortly there-after. Our intent is to do this right the first time. I am just as excited as everyone else about this platform. Subscribe to the thread and I will update as often as I am able to provide information.

Best Regards,

Jeremy Steinman

Whats the new news ? Is there going to be RWHP dyno results with different cam choices , compressions , maybe even some with forced induction.

Sorry about the delayed response. I just got back from Monsters of Mopar in St. Louis. Its tough showing the love to the Mopar Masses. So far I've had a booth at the Mopars at Indianapolis, Edgewater Mopar Madness in Cinci, OH, All Chrysler Nationals in Carlisle, PA, Mopar Nationals in Columbus, OH, Route 66 Muscle Mopars in Chicago, and of course Monsters of Mopar this last weekend. I committed to being out there for you guys is taking a lot more time than I thought it would but I am catching up as I can.

The engine will be going into my 300c SRT-8 in the next several weeks. We will not be testing different combinations until after initial road testing is completed. We are working on some cool show me stuff behind the scenes that I think will surprise a lot of people, but they still being discussed. Stay tuned...

We are still awaiting the Billet Main Caps. We will then need to install them in order to udnerstand the final numbers for Labor, etc. that will go into the Engine Build / 6.1L swap out program that we will start with. We should have more information in about 1-2 weeks. Again my apologies on the delay, but we are doing this right the first time and in consideration of our customers dependability needs.

any new updates?

Main caps should be in by Friday or Monday. We'll need about a week from there to iron everything out. Sorry for the delay but I am on virtual lockdown.

Hi, have any more specifics about the current build? Rod ratio now compaired to stock? piston height? New cam profile?

Anything new?

I'm subscribing to this thread. The stroker kit is the way to go. I didn't expect #'s as high as 560 HP and 600 LB/ft of TQ. (Horsepower is calculated, TQ is measured, and matters most.)

With full mods, post-stroker, the Jeep could run in the area of 1000 HP. EASILY. And with the traction of 4 wheel drive, the only force that will slow it down is air resistance. A beast like that should post 0-60 in low 3 seconds and 1/4 mile in 10's.

I was watching Dream Car Garage I think that was the name of the show.They are building a 6.1 that is going to go in Road Runner I think and thet are going for 500 to 750 HP Looks like a great project.

I think the entire driveline grenading as it tries to make its way down the track might slow it down also. The tranny, transfer case, and front and rear ends would be at its limits with 560 hp and 600ft/lbs of torque. That is if it hooks, I would have my doubts on it hooking if u slapped a blower on this motor. Sure would be a wild ride that no one would se coming.:)

The first person who supercharges this engine gets my vote for owner of the year, regardless of the destructive outcome.

Any prices yet ?

Jeremy,

I'm assuming those are custom headers? Would they fit the stock block/head? Any chance on selling those seperate from the motor/kit? Just curious.

Thanks

Sorry everyone about the delays in getting back to everyone. Here is an update from the other forums.

Here is a small update...This is from the LoneStar Shootout in Houston, TX last weekend:



Well, I decided I was going to drive my car today. I dialed in this morning at 12.78. Stupid me, now I just had to buy back for Breaking Out! LOL

I couldn't be more happy with the performance of this engine, even at 10.6:1 A/F ratios it can still put down the power.

Here are the conditions. Everyone was at the booth, so no-one was filming this run. Of course we didn't expect it to perform the way it did on these street tires.

Engine temp around 160-170 degrees by the time I was done with my 10 seconds burnout.

Here is the weather conditions today:

http://i136.photobucket.com/albums/q170/PowerPortedPerformance/10-22-06WeaterConditions.jpg

Versus yesterdays weather conditions:

http://i136.photobucket.com/albums/q170/PowerPortedPerformance/10-21-06WeatherConditions.jpg

How to Drag Race these cars: I burned out by auto shifting into 1st gear and revving up to about 4-5K RPM's for about 10 seconds, then chirped the tires (dry hopped it) to clean them off and staged, revved up to 1500-1700 RPM's, lit the second yellow by inching forward (a little drag racing best practice for our cars), then just dropped the hammer.

I was up against a Magnum SXT and he was gone off the line for a good 5-6 seconds before they dropped the lights down the pole for me to go. I knew I was going to break out a little, just because of how it felt going down the track, but I didn't expect this on these tires...


http://i136.photobucket.com/albums/q170/PowerPortedPerformance/DSC06809.jpg

yes!!!!:D



thats awesome. CONGRATS

This is sweet. i was thinking about supercharging my gc but im gonna wait it off. Well keep us posted and is there any estimated pricing or time frame we are looking at.

I am hoping that pricing will be finalized this coming weekend. I'll post up on all the forums early next week if there remains no remaining unanticipated or unforeseen costs.

Sincerely,

Jeremy Steinman

sounds like a good product

what do you guys have to say about HHP saying their heads produce more hp/tq than all others

Can't say. Never installed, ran them at the track and dyno'd them next to our Heads, so I don't have much to say there. I guess I could say the same thing about our Heads but that would be a little presumptious of me I think. Our Heads are consistent and our customers are very happy. See Here...

http://www.300cforums.com/forums/srt8-general-discussion/25457-426-rwhp-421-rwq-thanks-ported-performance-b-g-fixer.html

We can charge the same amount of money (FYI: our prices are going back up to our Base Price of $1,795.00 at the end of the year as the early bird pricing will be expiring), and by doing so increase the valve size, fully machine the Head, add valve guides, fully port the bowls, and the chamber side of the Heads creating a true HEMI Head that will produce drag strip / track race ready numbers. We just want to offer an affordable version, but keep in mind we are not limited in options for performance configurations, but it just increases the price. If you have more to spend I would glad to discuss options with you. :)

Next time get some vids!!!! haha nice runs! Cant wait to see what the future holds

Any word on the $$ ?
