I did a quick overlay in photochop of the 60-1 (to4s) compressor vs the gt35r. The 60-1 is in RED.
Looks to me that at 15 psi, the T04S's sweet spot is a little shifted towards more flow than the sweet spot on the GT35r. However, this might be compensated for by the fact that the sweet spot on the GT35r is 79% which is probably about 5% higher than the sweet spot on the 60-1. So I guess I"m saying those two factors may sorta even out.
Looks like the map is very similar between these two turbos. I'm very interested to see how this one turns out!!!!!

After you drive it, let us know how you like it.
Charts, graphs & dyno sheets and what not are nice but say nothing to me about how it repsonds in the car.
CCalisi, Stock or ported engine? Also why did you decide to go small and aim only for 400?

it means 79% vs 75% that its gonna heat the air a bit less. denser air = more power. looks like it should be a little ahead of a normal t04 with the same or less lag.

The motor was built by Carlos Gonzalez of G&S Racing. It has a LARGE intake port that was modeled after what he uses in one of his race cars, and a medium exhaust port. He also machined the E-shaft and balanced the rotors to within 15 grams of each other. The motor was built with 2-piece Mazda 2mm seals.
For those of you that don't recognize the name you can find a bunch of his race results on google. http://www.google.com/search?hl=en&lr=&ie=...os+gonzalez+rx7
Here are a couple shots of the intake ports in mid production:
There is some special sauce still visible in this picture
