Stroker + twin 67mm turbos = 718whp pumpgas daily driver
We recently installed twin 67mm ball-bearing Precision turbos on Wongy’s 4.2l G35 coupe. The result was a surprisingly quicker spooling setup than the Turbonetics 60-1’s, with more power on tap. On pure 92 octane pump gas (no meth or water injection) we were able to safely achieve 639whp on our in-house DynoDynamics dyno and 719whp on a DynoJet.
Next, VP C16 race gas filled the tank and we began tuning for more power. A little more boost yielded 750whp DD, above which we had problems from the ATS/Carbonetics triple disc clutch. More to come down the road.
Details:
IP 4.2l VQ, IP stage 4 heads, BC 264 cams, L19 head studs, IP Girdle
Twin Walbros, RC 1200cc Injectors, IP Fuel rails and lines
Cosworth Plenum and SFR Intercooler
SFR Upgraded Burns collectors, Precision PT67 BB Turbos, Greddy exhaust
Haltech Platinum PnP EMS with boost control, AIM Race dash with Wideband,OilPres,FuelPres,Boost

What were the problems with the triple disk? You say full boost by 4300, but I thought how to tell when full boost hits is to see when the TQ peaks? Is that wrong?
