no im running a stock rb25 motor with arp head studs camtech 272 cams. yeah not sure, might be dyno who knows. its never seen that kind of nm. similar setup cept plazaman gt3076 .82 and e85 made just under 600nm on same dyno. who knows. see how it goes at drag day in september. should trap ok mph im hoping. the cams are suited for a larger rev range, i only go to 7200. these might make more torque over that,but stock motor , keep it at 7200 so it stays together
