A fellow employee just ordered one and its about a week away. Does anyone know what these are putting down on rwhp? Also I believe they use a whipple right? Looks like I will have to get my blower soon.

 

I believe they are roushcharged with 430 HP.

 

ask the guy you work with --- he should be able to tell you[8D] I haven't really heard to much on that Roush.

 

Roush use their Roushchargers. Similar twin screws like the Whipple, KB etc but they employmore conservative boost/tune.

 

 

rated 430 crank .... google is your friend

Sorry but theRoush Charger isnot a twin screw but it is a roots type supercharger
I am not a fan of the little Roush tuner packages like this (drag pack, track pac, dork pack) but to each his own.

 

Roush, Saleen, & Eaton(roots) and Whipple & Kenne Bell(twin screw) are somewhat related. Subtle differences really...

Twin screws compress the air in the housing, and the Roots as it exits the housing and passes through the outlet(into the motor). Both are similar in operation, and mechanics. They use two opposing shafts turned by the motor to create boost pressure.


The biggest disadvantage the roots supercharger has vs. the twin screw is its thermal inefficiency - or its nature to produce high discharge temperatures. Meaning intercooling is a good idea if you plan on running a decent amount of boost.

 

saleen is a twin screw

 

The 415 bhp cars put down 340-360 rwhp.
So my guess is 350-375 rwhp.

BTW VMP Tuning has some kits for those cars that will kick them to 400 rwhp.
