[QUOTE="TARM, post: 457868, member: 578"] Also do not forget about pumping losses from higher drive pressure. @ 25 drive pressure is taking a guess in the 45-50 range but @ 35 I would not be surprised if its in the 80-90psi range. Also look at the intake temp. 25 as it takes slower wheel speed may be 130F but what it 35 was 210 F? How much of a change in "air density" on the pressure side is there? You can get pressure from air compression but you can also get pressure from air expansion from heat. Less air molecules just expanded to produce pressure. That is what I meant by it and that boost vs boost can be very different in terms of effect. [/QUOTE]
