Well, from the last time I went to the dyno a few weeks ago, We were able to get 409 RWHP at 14 PSI. This was documented In this thread.



Back then, we couldn't raise the boost higher than 14psi, otherwise the ignition was breaking up. When we returned, the problem persisted - until we found out the dyno ignition pick up wire was actually causing the cross-fire. Crap!



Well, once we eliminated the dyno RPM signal wire, we were able to increase the boost:



Numbers are:

336 at 9 psi (pump gas)

409 at 14 psi (pump gas)

xxx at 18 psi (pump gas)

XXX at 21 psi (C-16)



The car:

1985 RX-7 GSL-SE

Haltech E6K -Tuned by Crispeed

63-1 Turbo

Ford 8.8 Rear End (very heavy!)

Isuzu NPR Intercooler (Large)

720's & 1600's

Aeromotive 1000



Here's the video of it all:



High Resolution (89 Megs) right click, and Save-As <-Thanks Vosko!



Let me know what you think.



I'll post a full dyno sheet soon. The engine is definately capable of more power - We just ran out of wastegate spring. We could't run more than 20psi. Even with the Profec B set all the way. I have a 9lb spring in the Wastegate, and really should be runninng a 14+lb spring to enable higher boost.



It's all good though, and I am verrry happy with the performance, Especially



from a relatively small turbo - deisgned for street use, quick spooling.



Once again - Thanks Chris.

One badass sleeper. Sick ignition system also.

Direct- Those are awesome numbers. I hope to acheive something like that. What is the estimated weight of the car? It must be alot of fun to drive.



Good job, and congrats on it.
