you guys definately seem to have quality work though, well see what i need for this spring to get my twincharge kit on properly.. basically whoever will be able to do good work at a good price will win me over in the end... but the shopping around has to start now because it will be a long process!

 

how much hp can your mild lsj handle?

 

300~350whp.

 

So that equates to about 411HP at the crank with 15% loss from Drive train. is that accurate? Is drivetrain more or less than 15%, really?
I believe your conservative so lets say I tune for 350 on the street-daily driver. Could I reasonably crank out 500HP for the strip on a weekend?

 

thats rediculous doesn't the gm build book say that with just a piston swap this thing can handle like 400 hp?

 

Well yes but your missing the point of reference that JBP is quoting. WHP is the Wheel Horse Power not Just HP which is measured at the crankshaft. You may have known that and just missed that little bit of info. See my post #29 for the conversion.

 

kudos to ssnipes!

500HP... I do not recommend our Mild Crate for this type of power level at all.
