The following is related to us by Josh at SHO Nut
Performance. If you want something to shut up those GTP and ricer
types, then just tell them about this:
Went to the dyno today. After tightening my belt, I hit 465 HP at 7500-8000 RPM and 350 lb ft of torque at 6600 RPM at the wheels. Gone are the days of sub-300 torque figures ;-)
And, get this ... at 9-11:1 A/F for the most part ... so lots of room for improvement, and 'only' 15 psi. ;-)
That's 567 HP/427 lb ft at the crank, boys and girls. Not bad for a 3.0L with stock block, pistons and heads. This is essentially the ultimate ‘bolt-on’ car.
However, A/F was a straight line up from 10:1 at 7K to 12.5:1 at 8K, regardless of what chip was used, indicating that I was running out of 48 lb injector or 80 mm MAF at that point.
Well, at least I know that 350+ lb ft at the wheels is possible with a stock 3.0L block, stock cast pistons, 17 psi pulley, 105 octane race gas, and ice in the I/C. I'm sure that taking out fuel and adding timing will given even more. 1200 EGT's at 10:1, and rising to 1450-1500 at 12.5:1 at 8K.
Air intake temp (probe in airstream) was 100F at full hoot, and 45F at idle with 65 ambient.
