The most boost I saw out of mine was 64psi and I was pretty close to 1450 deg... I'm now running a Super B/GT4202...

I've broken the tires loose at 45mph... it's pretty sweet

 

Ok it might have been a little moist out.. i am in WA right now.. but it did break it loose.. yes still have a peg leg in it.. thats after the clutch.. does it ever end?? LOL..

My friend's '98.5 handshaker with RV275s and a Comp will break the 315s loose at 45 MPH in direct with 3:55 gears and a Power Lock. I thought that was normal with the sudden hit from a wire tap box.

 

I could break em loose with the 275's, but with these 150's.. OMG.. dont have to wait for the box to kick in.. as i said i dont even know where my waste gate is opening.. spools to fast then i'm in the defueler...grrr..
