PSP 05 Cobra on the Dyno

Well, had a some free time today so I finally got the 05 on the dyno. First I pulled the plugs out and gapped them down to .030 using a special gapper I whipped up for the unique 3v plugs.

Spent some good time trying different timing settings with the variable cam and all, and I am happy with the end result. The car pulls like crazy. These 3v heads are just AWESOME. I let off at 6200 just for fear of the bottom end coming apart, but you can see on the dyno graph that it just wants to keep going up. The Saleen/Lysholm performed just as I expected (I have experiance with these blowers anyway).

Final numbers are 430.86/405.70 SAE and 440.57/414.85 STD. Air temp was 90.8F, 37% humidity, and 30.0 on the barometer. Not the best day for making power, but that's what we have now.

Keep in mind that our combo is very simple. Saleen blower with a 3.4 pulley (stock is 4.0), PSP air intake/MAF setup, and a Bassani axle back. That's IT. Stock manifolds, stock cats, stock TB, stock everything else. For tuning, we added some 39lb injectors and a MAFia to extend the MAF range (only hit 4.15 at 6k).

Attached is the graph from the final pull. Enjoy!!

Bigcat, the 05 has variable cam timing, which is computer controlled. So we can adjust the cam timing via the tune.

Moondog, it does all fit under the stock hood, but it's still tight.

Halflife, I will have your PSP intake setup and SCT tuner ready for you this week. Just gotta swing by the powdercoaters and pick up the intake tubes.
