3.4L Whipple RPM Cobra My car getting busy on RPM's Dynojet!

690/636 with the 3.8" upper pulley and stock lower pulley. This was with a tank of 92 Wawa gas and I spiked it with some Sunoco 100 for safety. I shouldn't have, but I'm a bitch and was scared.
We'll turn up the boost and timing soon!

Depends on conditions and tune. They've had a turbo car make over 1000 on a stock longblock. However it took a lot of broken engines to get one that would hold.
Realistically at the 600-650 mark you want to start looking into aftermarket bottom ends. The only part that needs to be changed is pistons though. I have a 100% stock longblock, sans some custom forged pistons, ARP main studs, ARP rod bolts and different tolerances than stock.
The piston to wall clearance is tight and the stock pistons have a bad habit of melting. I would know, I blew one. Eleven days after I bought this car.
Correct. I'm running the stock Manley H-beam rods, and the stock 4140 Kellogg crank. They're good upwards of 900HP without a problem.

Damn, SICK numbers!
It's nice to see a good dyno video for once. Short, gets to the point, shows a clear graph. I'm sick of the 3 minute videos showing 2:45 of the car idling on the dyno and one pull at the end with no numbers, lol.

You could see the dyno sheet more clearly before I uploaded it to Youtube.
Thanks for the compliments.
