fresh build only making 210hp at 19Psi of boost. Very lazy doesn’t build boost till 5000rpm.
So my car just got broken in on the dyno. Fresh build with Manley 86.5mm pistons 9:0:1, Manley h beam rods, BC 264/264 cams. ARP hardware, ACL bearings, HKS GTIII-SS turbos. 3 bar map / Haltech 2500 ECU. After breaking in they threw it on the dyno and tuned it. checked everything. No boost leaks, no exhaust leaks, no shop rags stuck in intercooler piping. It made 210 at 14psi then they increased boost to 19psi and increased injector duty cycle and still the same 210hp. leak down test 10-15%, compression 120 120 140 140 140 140, waste gates are properly adjusted and car hits target boost level. Not sure what it could be. Do not have dyno sheet from shop. They’re going to take it out on the street and data log tomorrow. Anyone have an idea of what could be wrong?
