yeah blue rx3 went 9.4 with problems, bent the wheelie bars on launch.

 

I got the ignition system sorted out... Here are the final numbers.

741rwhp @ 28-26psi

 

great numbers. i currently have a T78 turbo, would this turbo fit without major mods ? would love to buy one

 

Ray, agian.. NICE!!!!

 

Sk8world are you coming to the race at silver dollar race way on march 14? its in Reynolds Ga.

 

How about a picture of the engine??

Is that the IFO? If so I was planning on it but heard they are tight on tech. I have no cage so I decided to cancel. I was planning on both Montgomery ones though... I really wanted to see a few cars from ATL. I have been reading about...
Who knows..... If my tune goes well maybe I will come...

 

Great stuff Forcefed! Thanks for sharing*

...Thats an amazing amount of power considering you're running on the stock E-shaft and relatively modest rpm. Especially considering the fact that you were losing over 2PSI after the 28.3PSI peak. The true potential had she held a full 28psi to redline would have been easily over 760RWHP... again, amazing.

What has ever been done about the stock e-shaft flexing under this kind of power? I thought they weren't safe to run with this much power? Not trying to downplay the numbers or anything(just debating on building another beast, and would want to know if I would need to do the 2piece shaft or not).

Either way, congrats to the owner and to Ray @ PFSupercars. Ray never ceases to amaze me.

That's why alot of Aussies use the supra gearbox in their rotaries.

Very nice dyno numbers. One question though. Why would you spend all that money on the engine and run a stock ignition? That should have been one the first upgrades done.

 

There is a BIG difference in making 7xx whp @24psi turning 7,xxx rpms then making 7xx whp @33+psi turning 9,xxx+ rpms. If clearances are correct, combustion pressure/flame speeds are all under control with the right tune, then there isn't an issue with the eshaft. Now I'm not saying this is going to be 100K mi engine package but there is a big difference in "a tune" and what someone like Ray has to offer. Good job with the build man!

Hey brown bear, those aussies use the older style supra trannys, not the 6spd Getrag boxes

BTW, insane power for 27psi

 

I know that. Ray built my motor and tuned it.

I know he did.....But that wasn't what I was getting at

Ok, I went back and re-read. I got ya now.

 

Word.

 

lota power= lota fun

 

NO ONE! uses the Supra 6 speed in ANY rotaries here in Australia, they are far to backwards and tight **** country to use a quality gearbox like that.

They do use the ghetto supra R154 5 speed and the various Toyota variants that they can by at an auto wreakers for $300

 

Wow i am def impressed...... i guess that just backs up choice for driving up to Maryland from Tenn when my car gets done.

So what you guys going to get my car with a 62 mm BW, streetport and build from DJSeven, and meth? Hopefully some big numbers.

 

thats a very nice number! haha

 

what ignition are your running now?? I need to fix mine as well.
