Hey all, I am looking at getting a T04B set-up for a future RX7, looking for ~350hp. 400hp max with the boost up.

I was searching t04b on google and found a few compressor maps. The T04B V1_V2 and T04B H-3 seems to be the best, but I am having trouble finding specifics on these turbo's. What does the V1_V2 and H-3 mean?

And when looking at the compressor maps, I want to be using about ~33 lbs/min when checking efficiency right?

No one knows that those numbers mean?

V1, H3, are compressor trims...

diffrerent trims has a different type of response, power output. you can find the one thats most suitable to your application by reading their compressor maps, their physical specifications.

I see many people get Q or P trims for RX-7s. those trims provide power through and rx-7 power band pretty well.

Those are to4 turbine trims not compressor trims https://www.nopistons.com/forums/pub...DIR#>/wink.png
