New RB25 Dyno Numbers

The compressor on that turbo is a T04R, 70 trim, 66.5mm., capable of 75lb/hr. The T3 Stage 5 turbine is almost as big as a T4's, and a more modern design. It's probably the biggest hybrid you can get.

 

My power figure (3.0 stroker) was made at 17psi.

 

I'll make this one off-topic comment and let these guys get back to RBs-

 

Z-Gad and I have found that big turbos (Seemingly too big for the L by conventional wisdom) do well on L-motors, somewhat making up for a lack of head flow capability (my theory anyhow) . He is running a T72 on his, and making in excess of 400rwhp on a stock F54/P90 with an Isky turbo cam.

 

I really need to get cracking on my next (non-L) engine, one with better head flow capability.
