OH MY FAWKING HOOLAHOOPS!$@!@!@$

Thats insane judge. Real good work.

What's the timing on the p-port since you decided to take advantage of that spot on the rotor housing (like it's meant for a pport)

And that bridge doesnt look too strong. You think you'll have any problems with it?

Good luck for the record!

but what i wanna know is why not go large streetported semi-pp, but cut the pp hole bigger than you did. thus reduced cfm from lack of a bridge would be made up for by more cfm thru larger pp.
A bridgeported engine will open the intake earlier then a streetported engine. Besides allowing a faster flow of cfm into the rotor chamber from the bridge opening, it allows the air/fuel to aptomize better in that rotor chamber(air/fuel mixture enters the chamber sooner, in comparison to a streetport engine.) the sooner that mixture is in the chamber the better that mixture will mix. Making the semi p-port larger interferes with the intake manifold, almost making it impossible to fabricate a custom manifold. Basically the intake manifolds determines how much of a hole your allowed to make for the semi p-port.



A good streetported engine will make about 250hp flywheel power. A good bridgeported engine could make up to 325 hp to the flywheel. I take that bridgeported engine and add a little help from my semi-port and a real big help from some N20 and I should reach my horsepower goal. of 575hp to the flywheel N/A N20

so what you're saying is the size of the pp is limited by your lim? taking that aside (lets say you built a custom im), wouldn't a big pp open even earlier than a the bp? sorry not arguing, just very curious. also are there limits as to where you can cut a pp? for a turbo application, i was wondering if it's possible to cut a hole higher up in the housing than where most people normally put it, to take out some of the overlap. also what do your exhaust ports look like for this motor, they must be ****** huge.

well thats an easy one, look at the judges pp, its relatively small and opens later than the bp.

Right now the fastest rotary engine on nitrous oxide is a Mazda Miata(with a 13B MFR engine) running 8.55 @153mph. I'm looking to run 8.49@155mph and become the fastest Rotary on N20 in the planet. An extremly hard goal, but I'm up for the challenge. If you guys want to see pics of the Rx3 let me know. Now that I have a digi-cam I could take pics and put them up.
Go for it man! :bigok: That's just badass. :smirk: :twisted: BTW, how much did this entire set-up cost?
