vette doctors gained 40 RWHP and almost 50 RWTQ. Hennessey got 50rwhp and 75rwtq with the addition of other stuff. COmpletely unreasonable? no, but I would expect more. So little is known about the limitation of a stock zr1 to make that call yet.
you guys will never understand…YOU CAN’T COMPARE DYNO NUMBERS!!! Saying Hennessey sucks cause it didn’t hit 600rwhp when some other a-holes did by adding less mods is so fucking stupid. Hennessey could adjust the settings on rip a 700rwhp pull if they wanted to. Dyno is a tuning tool. Compare the gains, only!
