I went to a carshow/dyno day today, and wanted to get another baseline rwhp in before my next round of mods.
My mods are as follows: 2.6 upper, dynotune. I have other items on the car, but they do not add to power.
Car made today 556.01rwhp, and 568.32ft/lb tq. SAE correction.
My previous dyno pulls were 558rwhp/574ft/lb SAE, and the same pull with STD correction was 571/587.
A stock Z won't do it. I am running 116rwhp more than the average Stock Z06.
In a couple of weeks, you can add 40more rwhp approx. to that figure when I have the 10% lower pulley installed and retune.
Looking at right at 600rwhp SAE with only upper/lower/tune..... everything else factory stock, manifolds, and exhaust. I won't concern myself with Stock Z's after that... and 2 months down the road are plans for either VMP TVS, or 2.9l Whipple. Should be a fun summer. :rockon:
Your car is by far the exception. Most upper only GT500's make 530ish to the ground, unless your tuners dyno reads high. What ET/Trap does you car turn?
