check300,

Like I said, turbos can be made to work well, but I've posted a dyno sheet of a 572ci we did with very low compression, dual 1195 BG carbs, on 89 octane. I don't have the sheet handy for the 5000-6000 range but it made around 1100hp at 5900. Compare the torque if you will, not sure what boost your running and every motor/dyno is different. I've took out some of the info, so that's why there's the big spots.

I'm reposting the dyno sheet so you can see it better, I cut out the boost, air fuel tables, etc. Boost is 9-10lbs. Dyno would not hold below 3000, but you can see the torque and could esitmate what it has down below.

Thanks,
Dustin

Payton: I think I can solve your problem with getting on plane. What turbocharger system do you have. How close to Gun Lake are you?

Ron P,
I believe the answer to your question is Bill Wishnick in "Boss O' Nova", a 36 Cigarette.

We are working on some 4 spd production boxes. It may have 3 with Rev instead of 4. We are finishing off the new drive and fnr shift on the fly boxes then we will put out the proto 4 speeds.
With the seateks we ran 4 speeds and the lambos we ran 6 speeds. 2 speed powerglides have too much ratio change. Depending on the motor we can change the split and the overall ratio. It is designed to drop replace the Huber.
That should keep you on boost.
