Normally, we ship the Stage 2 with a 92mm pulley that is good for 500whp on 93 octane gas. Kosstick wanted less power and got the 96mm pulley instead.

seems like the general increase per 1k rpm is 100 WHP just like my set up.

So this car is possibly making 530-550 whp?

No problem.

After examining your dyno graph, you are making 75whp per 1k rpm increase.

4500 rpm -> 260whp
5500 rpm -> 335whp
6500 rpm -> 410whp

Yes, the car we were testing was making 100whp per 1k rpm increase and could have made 550whp, but we stopped the pull because it was more than we wanted to make.

So correct me if I'm wrong but as it stands the upper limits to the head unit at 14psi in this application is good for 550whp with the proper pulley. Meaning that if one would want to go even higher it would have to be via drop in lower compression pistons and rods.

Its safe to say that the Stage 2 kit is a beast, a user can get up to 14psi and 550whp which is more than needed for the street. 550whp and 400tq is a dream come true for any Z owner.

Mike, On my new dyne I think i was making 100 per 1k but i could be wrong, Seb can you post the final run with 463 / 335?

Probably 550 WHP 430 tq

I'd be very happy with 420whp.

We don't recommend running the stage 2 at 14 psi on a stock block with pump gas. If you are trying to get more than 500whp from the Stage 2 Supercharger kit, you're going to need more octane.

Don't worry Mike I won't mix up the SC capabilities with the TT, both of which are great products. I just like to get into the nitty gritty of it all. As of now I already have an oil cooler and UpRev tune so I would eventually be relying on you guys for hardware and fuel system upgrades if I don't go e85 before that. I know you guys are busy so I really appreciate the numerous responses. Keep up the good work.
