They haven't shown up in my box yet.4" bore 3.59" stroke 6.35 rod 8.5 compression. I sent you the cam specs for 2 cams? did you not get them? 1.7 rocker ratio intake, 1.6 exh on the 234 cam.

Just give me your best guess.Its Dual BB. I can go out and measure the radius but just an estimate gonna be hard to measure exactly?
Well your turbo seems bigger than mine, it could be compressor/turbine wheel size is larger in your set up.Norbs,
Not sure what compresssor/turbine your planning on running but I found that boost won't come in as fast as you think with a large size turbo. My dyno log showing only 7.5 lbs boost at 4500, 25 lbs at 5800, and 35 at 6600. I think the turbine is not ideal for spool but performed well with regards to backpressure.

Donnie these turbos are rated for 1150 HP, I think you have to multiply something because its a dual scroll housing, are your calcs based on single scroll.? That particular housing i measured is 1.01 a.r I will be using a 1.28 a/r probably. I sent you the coy of the turbine map too.A .60 a/r and 2.5 radius gives me a nozzle dia. of 1.38. I'm not even going to try doing a calc with that nozzle size. It's just too small.
That does change things. I thought I saw someplace that you were going to use a .60 a/r. I'll see how these new a/r numbers work out.Donnie these turbos are rated for 1150 HP, I think you have to multiply something because its a dual scroll housing, are your calcs based on single scroll.?
