Weekend Dyno >650 RWHP TTi Street Turbo Well I hit my goal over the weekend. My last dyno I hit 643rwhp/621 rwtq and I was pretty happy with that since the kit was never really designed for these hp levels. After chasing down some gremlins over the course of the year, I hit the rollers this weekend.

With the the WG spring at 10.5 psi and the manual boost controller turned all the way up I did theree pulls dialing in the AFR and timing.
Anyway the Results were:
1st 659.5hp/625 Tq (Actual) 642.4/608.8tq (SAE) This run was odd, cause it didn't start logging till very late in the pull.
2nd 671.4hp/758.1tq (Actual) 653.6hp/738.2tq (SAE) Good Clean pull
3rd 665.5hp/802.6tq (Actual) 648.2hp/781.7tq (SAE) Brake Boosting for the Tq!
The Combination:
TTi Street kit T-76 (on center, .96 turbine ar) Custom FMIC
Futral 370 9:1cr short block
AFR 225 72cc heads w/upgraded AFR springs
Comp Cams 224/224 Cam .576 lift 116 lsa (custom, idles at 650-700 rpm)
Ported LS6 intake (LS2PortWorks) Port matched to the Heads
Stock Throttle Body
60lb Motortron Injectors
Dual intank 255's
Snow Methanol injection (100% Methanol)
Fuel controlled by Accel
Ignition by HP Tuners
SDPC Ported Oil Pump
Transmission is a Speed Secrets 4L65-e
Converter is a PYE 3400
Moser/HighSpeedProducts 9" w/3.50 gears and a LSD
Wheels were 17X11's with Hoosier 335/35/17 Drag Radials (Thanks again Mark)
The AFR ended up a bit rich at TQ peak 10.1:1 then ending up right at 11.5-12.0 at HP Peak. Timing was set at about 16.5 at Peak TQ and 20.5 at Peak HP.
Going over my log files I have officially come to the limit of the TTi Street kit. I had my Boost controller pretty close to max. I was making 18.7 psi at 4800 rpm that would gradually drop to 15.5 psi at 6300. I am pretty sure thats all she's got. The fuel system seems to be working pretty well, as the Turbo is maxed out and the injectors are about 94% duty cycle. It would be really interesting to see what the exhaust manifold pressure is, I am guessing around 45-50 psi (no exhaust scavenging here!).
Keep in mind, if this were a manual car, it would have been well over 700RWHP.
Special Thanks go out to:
Turbo Technologies for a great kit!
LS2PortWorks for a great hookup on the manifold
Scoggin Dickey Parts Center for all the odds and ends (Best, Hands Down!)
Here is one Dyno Graph I only pulled it up to 5900 rpm on this pull (the Blue line is WAHUSKER's D1SC 402). Yes its Actual, but the SAE numbers are above.

Dang son, that's some stump pulling power and torque. Any ET's with the latest power settings?

Very impressive!!! I'd be happy with 525 RWHP on my M6 car.
How much smoke do you have with your setup, any? Do you have a website that shows your whole setup?
EDIT - Woohoo, this is my 2,000th post!

Do you have any current pics of it along with other pics of the current turbo system?

I really like my little cam, LOL, I like keeping the RPM's down where I am not killing the rotating assy/valve train. As for the turbo, it really is done, you have to remember that this is an on-center housing. If it were a Tang it would have more in it. On-Center=too much back pressure.

That was a very impressive dyno session Ryan! Your car is still the one to beat in these parts. 
I didn't think I had found enough hp to beat you, but I thouhgt I had you covered in the tq category. Oh well.
Should be a lot of fun this weekend at the track between you & me & Ellis all going for new bests.....
