My friend ran a 7.4 @ 94-96mph with roller cam(206 I believe), alky injection, 6262 turbo, stock intercooler, pi converter, and 21-23psi. Running a chip for alky but something is up because the car gets pinging on top end and resulted in blown hg first part of last season. I know the tune is off and could be a lean condition or too much advance. Does not having the tuning tools to dial it in. He cut the boost back to 16-18psi after the hg failure but still run 7.6's 92-93mph. This car should be running closer to 100mph? The car 60's in the 1.6s.
