^ a change in temperature might make a 20whp difference. No one is saying the supercharger is blowing hot air either. I am assuming charge temperatures are hotter with the sc, but not enough to justify that much variation in hp. Remember that there is an intercooler between the turbos and the engine as well as between the sc and the engine. That cooler should be able to bring the air temps down to similar levels.

5psi is not harder to imagine than 20psi. Its the same thing.

Are we to assume that this supercharger is blowing hot air by your logic? I certainly hope not. We know charge air temp makes a difference, but their tt kit made like 400 at 5psi. How is the sc making 400 at 10psi.

I think I'm going to ease up on asking any questions here until the official numbers are released, there is not enough real finished kit data, so we are all just making assumptions... and you know what happens when you assume.

Also, Z Eliminator, either you are really talking worst case scenario or the kit has a long way to go because 10psi on a high compression motor like ours should net more than 70hp.
