Yes that is correct,
stock turbos, 680cc injectors, stock gtr intercooler core and 15 PSI netted 392rwhp and that (in my car) should of had me in the hi 10s but the rear-end kept breaking on me. Best time was a 11.138 at 127 MPH and a 1.7 60 foot. You do the math knock of 1 or 2 tenths from the 60 foot and wam... 10 sec pass.
1.7 60 foot was with allot of wheel spin. That’s the only thing that saved the rear-end for as long as I was running it. As soon as I started tweaking tire pressure and suspension settings is when I started breaking things. An automatic conversion would have done wonders.
