check out www.machperformance.com . They have some info on the ATI system. I believe with just the charger its around 275 rwhp, with headers and exhaust 300+.

Actually, if you do the engine builders rule of thumb (20% loss for autos) then its about 353hp at the crank :)

Maybe my math is broken?
282 + 20 % = 338.4

282 + 22% = 344.04

282 + 25% = 352.5
:confused:uhoh:

You cant just add 20% to the 282 to get the overall power....that would be adding 20% OF 282.

Take 353 and minus 20%, then tell me what you get. :)
(Just had a math exam yesterday!)

The actual equation to figure out crank, would be:
282hp / amt of power not lost (80%) = 352.5hp

Superchargers are usually a gain of 50% or more (6-8lbs of boost). In the case of the last install, we gained 86% (at the crank) :)

So far, almost all of our customers have gained approximately 80% 90% hp.

No, that is just the kit itself, if you want us to install it, it would be extra. The kit includes everything to do it yourself.

Definitely NOT recommended, if you are planning on driving this anywhere than the strip. It has been done, but the advantages of air/air far outway the advantages of air/water for street purposes.
