the n/a 3 rotor at pdmracing.com made 300whp with 91 NA rotors and exhaust work. this is their statement, not mine.

 

Any updated?

 

Here it goes! Did dyno yesterday! The N/A PP w/ 10:0 cr and a Weber 51 IDA make 284 hp@8600 rpm. Torque 180 ft/lb@7500 rpm. That was 8 more hp on top but 11-20 hp more in the 5-7000 rpm span. Very drivable from 3500 to 9000 rpm according to my dyno operator. The engine will sit in RX-7-83 rally car which gonna compete in a tarmac cup in July. I will do a new thread in the Rotary Performance section with more details tonight.

 

Finally got around to getting the dyno graph...



We had other runs close to 200 lb-ft, but this one was the cleanest up to redline (7kRPM).

Is that close to the stock twins?

 

Thats great! You have just managed to encourage me to take my turbo off & build a set of headers! That should help get the car going sooner rather than later!

 

Nice graph... I added you to my page at http://www.catenet.net/dyno.php

Thanks for the dyno!

An interesting comparison... a few close-to-stock FDs vs the RETed's dyno...

You can see that the shape of the powerband is very much the same, but without the troubles associated with the FD TT system. This is a compliment for the FD TT system (when working properly) since it makes the 2 rotor drive more like a 3 rotor NA (flexible).

I'd still rather have the 3 rotor NA though

 

stock twins did 270ish lbsft

 

Hey Wargasm thanx for the submit!
I didn't how to do this, so I was relieved to see you had taken care of it already!

It's not my car, so I was wondering if you can change some of the owner info?
I just put up the dedicated page for this car on my website...
