And I am presuming you know we are not talking about RB's! ...only playing!
Cannot figure wether your saying the Dyno is FOS or my tune is FOS!....if it's the dyno take your car down to Vic and run it up. Every dyno is out...either up or down...but I have never seen figures that are more than 10-15KW's different on the same car!....do you think I have never sat on a Dyno before!
E85, GT30/71 core with Garret BB set, VQ25det, 24-25PSI, MT 2WD highly likely to hit 350RWKW's!....considering Scott is running a smaller turbo and has hit 300AWKW's on 17-18PSI and would push more but his GB is not handling it I am thinking it's a pretty good indication!
Also consider this, I am already doing 268AWKW's(Scott ran approx 245AWKW's on BP98, 17-18psi same setup) on BP98, 15PSI, Auto 4WD....the only reason we stopped was the GB!
Anyway rant finished.....does 268AWKW's on BP98 not support your 450hp cartridge theory anyway?
P.S. My figures on my turbo tell me it's good for 500HP btw!
