Hum, What mods First??

[PPP-Tim]

As some of you may know we are trying to decide what to do to our Challengers. Our first 4 should be arriving shortly.

What would you all like to see done to these cars?

PPP 426 Strokers
Turbo
Supercharger
Head and Cam packages

We take delivery of a customers car next week for a 426 Stroker instal and I will keep you posted with pics of the build.

Thanks,

Tim C

Hi Tim,

Thanks for asking, you guys are building some beautiful stuff. I would like to see a package that is refined enough to be a daily driver, without any weak links. Probably a 426 with no power adders, for me. The keys to me would be:

1. Comes with a complete drivetrain that will hold up to the higher torque 426:
-I've heard that the trannies aren't strong enough to take torque a lot higher than stock, so a beefed up tranny would be on my wish list.
-A torque converter as well, both for durability and a higher stall speed.
-Rear end: Is the stocker strong enough?
-Is a driveshaft upgrade required?

2. Tuning that is optimized not just for WOT performance, but driveability and emissions. My supercharged Lingenfelter 383 passes smog through the tailpipe, after they spent countless hours dialing in the tuning. A properly tuned 426 with no adders, but runs smooth, would be my choice.

One question- I've read that boring and stroking to 426 cubes thins the cyliner walls and pistons, so long term durability can be an issue. If this were the case, I'd take a 392, provided it is durable. Do you expect any longetivity issues with the 426?

Thanks, and keep the good products coming!

I've got a question as well. Are the stock 6.1 internals strong enough for a supercharger?

[NOTSURE]

I read somewhere the Challenger was specd up to 700 hp ..I also hear SC are not good for the hemis.Will it be able to handle a super charger with the stock crank is the big question.
Dont know if I'd push it with a 45k car though.

I seem to have lost the link but this conversation happened a while ago and someone posted some links for Chargers and 300's with the 6.1 that were supercharged, included pricing specs etc. Sorry I can include some reference links but I'm sure if you google it you'll turn up something.

No idea if its a good idea, but we know its being done.

[NOTSURE]

I remember that as well wasnt it a company out of Chicago making the challenger into a cuda that was super charged.If I rmember right they had several models as well.
Ill look around and maybe find that info.

Thanks Cuda340
Hey any word on your cars staus yet?
I do wish you well in your efforts.

Great questions:
The stock transmission is a pretty stout unit. We have been successfully running 450-550whp with little issue. Failure seems to occur around 600whp.

The stock torque converter is reliable at those same numbers, but it will slip with anything over 430whp. An upgraded converter is recomended for cars over 430whp.

The rear end is also strong enough to handle the but needs a better limited slip differential installed.

The axles are a major weak area. The LX cars will snap axles quite easliy on drag radials with over 430whp. If you dont plan on running drag radials at the track, you "should" be ok because the tires will just spin and not hook up.

I dont know of anyone breaking a driveshaft yet in an LX car. When the manual transmission car become available, we will begin to see failure with higher horsepower cars.

All of our PPP 426 strokers are tuned not only on the dyno to WOT, but extensivly road tuned for maximum driveabilty. You can start it up on a cold morning and drive to work, a perfect 480+whp daily driver.


392 vs 426 :

Yes, in theory the 392 is able to handle more abuse then the 426 due to its thicker walls. But we have not had any failures with the 426. For most applications the 426 is perfectly capable of handling the daily abuse our customers dish out. Example: If you want 480-550 NA whp, the 426 is perfect for that. If you want to run 15psi of forced induction, the 426 is still more then capable to handle it. If you want to run more then 18psi, then maybe we would look into the 392 stroker as an option.

The 392 is common because for those with 5.7L cars, it is the largest displacement to easily stroke to, while the 6.1L cars can go to 426.

Another good question.
The stock internals are good for 5-7psi. If you want to run more boost, then you would have to get all new, forged internals. Pistons, Rods and Crank. We do this weekly, if you have any questions, feel free to call.

Thanks Tim, do you guys carry stronger axles and torque converters?

Yes, we have 3 different Converters available and they range from 2600-3600 rpm stall speed.

We have 1000HP axles availale for the 5.7 and 6.1 LX cars and will also have Challenger axles in the VERY near future.

Thanks,

Tim
