Matt was checking the Tempeture of the coolant, intercooler and manifolds after every run and they were not that hott! They were doing way better than he expected, The cxracing ebay front mount was not even hott after 10+ pulls, And there was absolutely no pinging at any boost level, the correction at 25 psi in dynojet numbers were 615 rwhp an 530 torque very nice indeed, Im very impressed with the turbos and how they performed, and the only way i went forward was after looking at your dyno sheet saying that they can be really good turbos too :) When you got 604 rwhp at 32 psi were you running like the old school 2 1/2 down pipes or what was the set up??
