Finally got the car on the Dyno this weekend, sorry the graph is a little on the suck side I didn't realize the torque & HP scales weren't the same when I printed it...was in a hurry. The torque is on top. The boost was running off the spring since I forgot to turn on the boost controller. About 15lbs at 3700 dropping off to about 12lbs at the end. I run a 14lbs spring.

I run a big street port, water injection, 2x550's, 2x1200's, cosmo pump, ASP IC, Power FC, AVCR, RaceLogic)

Needles to say the car is a blast to drive with this torque curve even though I'll probably never hit the magical 400hp # with this little guy.

Enjoy

(Note to self - turn off traction control on the Dyno...DOH)

what turbo?

I think its the smallest one they make for the RX7. They say its good for about 350hp but thats probably thats at the flywheel from what greddy says. I have no business making that much power from that weeny turbo. :-) It was an ebay special about 2 years ago, to good to pass up. I've had the down pipe fabbed into to exhaust and then coated the down pipe and turbo with turbo X from techline coatings.

I think I can squeek another 20-25hp with a little more tunning and actually turning on the boost controller this time.

I've done a fair amount of porting to the turbo to get more flow out of her:-) Actually got another 1.5 psi on the top end after I matched the intlet to the turbo to the turbo manifold. It makes about 12-13psi maxed out up top.

Whats interesting is tunning the car for 12 to 1 vs 13 to 1 lamba doesn't really make any more power running lean. However getting down in the 10 range looses power

Pic of my car below. racing my friends 500hp cobra. I ran 12 flat 116mph (clutch was slipping in 3rd and had to let out) he ran an 11.9 @ 119 or so then broke an axle on the next run and went home on my trailer...ah

If thats a rotary engine and your running that a/f on pump gas its not going to last much longer.

My car is the Yellow one in the pic above :-). If I wasn't running the water injection I'd be more inclined to agree with you. I did several plug checks after my dyno runs and they looked great. I got 6 more HP just by swapping to newer plugs.

Runs where done in 4th gear by the way.

You can run a bit leaner with water injection...as long as you are injecting enough.
