Hello all,

Found this post on another forum from Dustin Whipple about their testing of the Whipple S/C kit on the 2005 GT with 3V 4.6. Figured anyone interested in this would like to know.

"Some may have problems supercharging the 05' stang, but we don't. We will be putting the motor through vigorous testing including WOT for 100 hours. No other company will do anything even close to this. So our system WILL be the most reliable power adder out there. We have a 4" thick intercooler, louvered fin, bar plate design, 16fpi. Theres a 1.5 gallon reservoir, a 4" fluidyne heat exchanger, 2.3Liter SC, 4" inlet tubing, enclosed air filter, etc.... The stock hyperutetic piston is certainly not ideal, but this style has been used for years, as long as you can control knock, the piston will live so the challenge is doing the proper testing, I'm afraid most of the aftermarket can not offer such testing. The AVL cylinder pressure transducer system with software and equipment is nearly $300,000. The endurance test, whether you pass or fail is over $50,000. We did this with our Ford Ranger project. 50 hours at peak torque, 50 hours at peak hp, 11lbs of unintercooled boost, on the edge of detonation. That was the 3.0 Vulcan engine, a far cry from the 4.6 3v Mustang engine.

I don't see customers shoving insane levels of boost like prior setups, the market I think will go more to the "bolt-on" setups vs. the custom setups.

We use all Ford calibration software, authorizied by Ford. Our head calibrator is one of the most sought after calibration experts involved in the Ford communnity. We had our 04' 3v running quite some time ago, the first to my knowledge to run with the electronic throttle.

Price should be in the mid $4000 range, but thats just an estimate, but I won't truly know until I finish the BOM."

Thanks,
Dustin Whipple

Thanks for the info, I am definately waiting for both Whipple, and Kenne Bell to put out thier twin screw Superchargers, then decide on which one to get. No way I will put a Centrifugal Supercharger on my 05.

Whipple is going the more "supplier responsible" route by performing the lab testing and seeing exactly what can the 4.6 3V handle and maximize engine longevity. Anyone can go out, spend 5k, bolt a S/C to the '05 and over do the boost and have an 11 second Mustang...for 4 runs and then the engine blows due to way too high boost. I would really like 400+ RWHP with low boost and see 100,000+ miles to boot. I would pay 4k for that if the engine bay doesn't get too clap trappy or have too many moving parts or the cooling system isn't over the top.

I really like the Saleen S/C so far but, I have not seen any release from Saleen as to what this things limits or life expectancies are, and at 5k I think it would be welcomed.

I agree, I think a compromise is what most "Street" guys want. If you can get 400 RWHP on pump gas and not have to spend a fortune on the rest of the car, you get something that is going to kick the pants off 95% of everything out there, including most of the RICE BOYS!!! I think the saleen is 5psi while the whipple is 7-8. Both are in the 4-5k range in price. Interesting thought is would the warranty be intact if the Saleen S/C was installed by Saleen dealer???? Another point to consider is adding Water/Meth injection to further cool the intake air temp. I've heard this works well on twin screw. The cooling system is the weakest point from what I hear, but there are some mods and alternative coolants that can be used to aleviate many of these issues. Hell, it's only money....... your kids can eat at a friends house!!
