824.x at the wheel, 946.x at the crank. Just JWT C2 exhaust cams listed in build. Don't need any headwork. Just little twins, Zonarotor turbo's equivalent to GT3076's.

Too early to tell. I know of a couple of cars using them with some additional stuff. It is the same concept as the RJM. CSS installs them with a CNC.

So you're going with 100 psi on the new build? Nice

LOL, you are a funny guy. We as a group are having a hard time keeping them together at 17-24psi. 100psi, not happening.

Boost pressure isnt really relevant to the problem. Engine torque is a much better indication of cylinder pressure than boost is. Not to be nit-picky, but I hate talking in boost psi when in itself its so irrelevant

True, my diesel truck has around 1200ft/lb of torque and 625hp. I only make 43psi of boost. I think the engine is 16-17:1 compression ratio. On the 5.9 Cummins the torque is real close to double the HP. Sometimes more. Playing in the diesel world, turbo drive pressure and timing will also effect cylinder pressure.

Pick all the nits you want. Everyone that matters knows that you know what you're talking about and aren't just being pedantic.

The next motor is going to be built by Mazworx. I have made my decision. I am excited and nervous. Waiting for the bank account to grow in the next month to kick it off. My money tree will be in full blossom by the end of February. I hope all goes well or I will be waiting a while longer.

Interesting! I was on a hub dyno once, very convenient to work with. When I went last Saturday I the operator did 12 second runs. I thought it was a bit long..
