My S/C kit has arrived

[thump_rrr]

I have been spending to much time researching and not enough time thinking!

So far on the SC front I've drawn the following conclusions;

1) If I want off the line performance I go with either a roots or twin screw piece of kit.

2) On a stock block/internals I want to keep power to 400-420 rwhp.

3) Of the the two types of SC listed above my best bet is Roush or Saleen.

Any suggestions, comments or fresh ideas are welcome!

Cheers!

I have been offered to put a roush on my car for cost and I've declined because the performance isn't there for what i want. I'm running 12.69 N/A with stock gears!!! If i go with a 4.30 I should be in the low 12's.

The blown Saleens and Roushes with factory Saleen or Roush tunes are in the mid 12's so it isn't worth if even at cost to go that route. The Roush is a roots type which I won't consider for major HP gains.

When I go blown next winter it'll be on a forged shortblock. My goal is 550-600 rwhp. My choices will be between the Saleen with JDM Engineering upgrades, the Kenne Bell which is a complete kit with injectors and Boost-A-Pump, or the Whipple which no news is currently available.

I think the Kenne Bell Boost-A-Pump is the proper method of upgrading the fuel system If I can incorporate it into the Saleen blower with it's long runners for low end torque I'll have the best of both worlds.

For 400-420 RWHP the Roush should be good but where can you go from there if you want to upgrade further. We know that there are upgrades from JDM Engineering if you go the Saleen route.

For the concern about heat from super charger This is printed in the instruction manual you may find interesting.

Information about he Roushcharger bypass system
There is a great deal of misinformation about the function of the Rouschargers bypass system.The Roush charger is positive-displacement pump;thatis, as long as it is rotating it is always pumping air. During low demand or high vacum operation( idles,decelerations, and light throttle cruise), the pumping action is less desirable.as it creates unwanted heat and noise.The bypass circuit, when open, prevents any pressure build up across the Roushcharger and allows air to circulate through the rotors,allowing the Roushcharger to idle freely during these conditions. The result is reduced noise,and by reducing heat buildup in the intake , significantly improves street and strip performance. As throttle demand increases the bypass circuit is closed, resulting in full performance from the Roushcharger. The bypass circuit is never used to limt or control boost during full-throotle operation and
defeating or altering the the bypass function will not result in improved performance in any condition, will result in poor divability

MY Roush Kirt came with different injector, spark plugs etc.

Thanks, Good to know.

The only thing I don't like so far about the Roush is that it's a non adjustable program. No 2 cars are identical and adding things like headers will throw off the A/F ratio which cannot be changed by your local tuner. Given enough time companies such as JDM Engineering which has been modding the Saleen superchargers may do the same for the Roush.

The only reason I keep refering to JDM is that someone local to my area has a JDM prepared Lightning which runs flawlessly in the low 11's. I also saw their moddeed Saleen powered 05 run 11.69 at the Fun Ford Weekend in Epping NH. along with about 10 customer cobras and lightnings. I spoke to Jim and Jim Jr. and I was impressed with their whole operation.

Curious, what upgrades do JDM Engineering have to drive that level of power out of the Saleen?

JDM haven't reached these levels yet due to running out of fuel in the 475hp range. They at last look were still on stock internals. Jim jr. had told me last August that they'll keep adding power till they blow it up before they build a forged bottom end.

They have larger injectors, smaller (more boost) pulleys, and fuel system upgrades
