467.5HP Dyno
I finally got my car on the Dyno this weekend with Steve Kan doing some tunning for the Phoenix Rx7 group. I loaded my car up and headed to Phoenix for a day of tunning.
I asked for a conservative tune being that this car is street driven with occasional track use, so we aimed for a 10.8 AFR across the board and which we got.
We hit 467.5 at 19psi with a 50/50 mixture of 91 and 101 octane gas. That was around 7000 RPM but we lost the tack signal on that run so we missed out on the RPM and torque measurements. The next run at 20 psi we saw 466 HP at around 6k and then Steve let off sensing a slight ignition breakup. This was on BUR9's all the way around.
On pure 91 ocatane we saw421.8HP @ 7100RPM 15-16psi with 322 torque and so this will be my "street trim".
I have an aquamist setup with was not functioning so that'll be turned on, and I'll be modifying my ignition, adding another fuel pump and modifying my turbine houseing/DPsetup and a few other things.
I'll try to get the graphs posted but they are really light and my camera isn't picking them up, so I'll have to find a scanner.

Congrats Chris!
All I can say is it was DAMN exciting. You're car is incredible. You could hear it several blocks away screaming on the dyno.
Steve definitely knows his stuff when it comes to tuning. Awesome day for everyone!!! Good luck... quit shaking (I think you know what I mean
)... and wipe that smile off your face

Carl,
Steve told me this weekend that he has not turned any "group" of people down yet in 2003. You need to have a minimum of 5 people at $300 for him to come out. That's why it's a good idea to have people prepay you and hold the money. He can do up to 6 cars per day, but it will be a long day. PM me and I can give you more details!

Haha. My parents wouldn't get in the car My mom love her ' 96 5spd Gt mustang, but the cobra was too much 
No was did she need to get in this one haha.
After a ride my neighbor did say that it was the fastest thing he's ever been in and that when I took his wife she was going to "**** her pants" haha, guess I'll put some plastic in the seat before the ride!
I love these cars!!

Oops. I guess dyno numbers are supposed to be in the performance section. Oh well.
bodybag huh? I'll have to consider that one. I was going to go with the good ol CAR X7 that I used to run. Wow, yeah I drove the car to work today and itwas ~40degrees outside this morning. WHEEEEEEEEE! hehe
Darn it if I don't have to go to another site for a meeting in an hour! Gotta drive the car again DANG! ;D
I could get used to this

Synapsis, nope, no SIR yet. I just got it running really this past weekend. I guess since the track is closed I'll head out first of the year. you should come to our next get together. I think J-rat is planning a christmas party or something... check out the west forum.
The Tials actually work very well. I can honestly say I can run on WG pressure (.8bar) with zero creep... all the way to 8k. The only issue I have found as you suggested is that I burned through the gasket on the WG off the secondary rotor. I ended up using a metal gasket off some honda motor (Iguess) and it seems to be holding up very well.
