492RWHP 05 GTO Heads/Cam car We had a car that did very well today and we wanted to share the results.
Let me first say this car is the exception and not the rule so please dont always expect these results.
05 GTO
Manual Trans
Stock Wheels/Tires
What we did:
ET 225 Heads (EDITED .. Not 215 heads)
SI7 Cam
Kooks 1 7/8" Headers (Offroad)
Corsa Sport Exhaust
FAST 90 intake manifold.
Needless to say we are very happy with these results as is our customer
Attached is the graph.

finally some decent ETP numbers awesome numbers for a 215cc head. seems kinda odd how the TQ spikes up from 4000-4500.
would really like to see some cam specs.

Just as I suspected...put the smaller runnered ET heads on a larger motor and keep the dynamic compression nice and high and you'll see KILLER power under the curve even with a FAST 90.
Just look at that torque at 3000 rpm. Benchmark is CID in torque by 3000 rpm and CID x1.25 at peak.
364 rwtq benchmark, 370 rwtq actual at 3000 rpm
455 rwtq benchmark, 445 rwtq actual at peak (dang close)
Very impressive package!

It's been just a matter of time for some of the dyno results with these heads. Since the first engine that I've seen with ET's on it, I new more would start showing up. Congrats on the results and nice job to Speed Inc.

Yes I had thought they were 215's but after talking to one of the other guys here I realized that was not the case. We had ordered them back early in December so it was quite a while ago
