Peripheral ports

Grant Monkhouse · September 07, 2011, 04:13:52 PM

I was actually referring to build cost. But I can see your point with the fuel. However any self respecting rotor head cannot complain about mpg no matter what shape or form the ports are.

Matts car was too quiet for a 3 rotor PP anyway, maybe he is best off with the side ports.

I bet it cost him more to convert to a side port from a PP than it would to fill the fuel tank up a few times? Lmao

A twist? How big are your PP\'s?

I\'m fully prepared to get no more than 16mpg on a good day from my stock EGI since I have a heavy right foot and like to hoof it and have fun when I drive!

If you ain\'t driving with a grin you ain\'t doin\' it right! :Laugh

Quote from: Lacey;786997Good interesting, or "waiting for it to **** a brick" interesting? :p

Superchargers are very awesome on rotaries. Seen a couple of the ozzies cars with them on. I meant interesting as I. ThAt a supercharger is more for low end grunt, instant power over a laggy turbo so you would in theory increase the power band of the PP and make it more driveable around town in my eyes. You would just have to get one of the right size that didn\'t run out of puff towards 8,000 rpm

Exactly, I don\'t car what the mpg so long as I have fun. And embarrass a few people along the way.

Again this is purely a guess, but I think he may have swapped engines with Mir - Since Mir now has a 20b P/P in the works and matts engine looks just like Mir\'s did...

Ahhhhhh, I see! Yeah I was looking at one of Rotrex\' more substantial superchargers, seeing as it\'s belt driven it\'s lagless (virtually) and compliments the lack of low end power that comes with a PP. I;ve seen a couple of FC\'s with a screw-type bolted on the top and they\'ve had to cut the bonnet open to fit it and it just looks ugly, I;d like something under the bonnet, hidden and out of view, to give somewhat of a surprise than being obviously in-your-face blown and spoiling the surprise of it.

Exactly!! If your sports car doesn\'t put a grin on the face, what the hell have you bought it for?? :Snoring

Wait so after syed saying he doesnt like PP\'s he could well have a PP turbo in the works?

Well that is the way I would have gone to gain the magical 1,000hp he after. Hope he\'s prepared for some massive noise then!

Just thinking here, I get banzai magazine every month and one of the writers has super charged his civic type R, with a rotrex supercharger. So if you could find which one they have used on that it should be more than ample enough to keep up with the revs of the rotary and you won\'t have to worry about all that heat that normally comes with a turbo!!

And it will fit under the bonnet as they are a Paxton supercharger( basically half a turbo but belt driven and geared properly) as opposed to the screw type that is big and bulky and would have to sit on top of the engine.

With a Paxton you can also run through a small intercooler the keep air temps lower. Or dont bother and just Inject water straight Into your TB?

Yeah that\'s what I was thinking, as it\'s belt driven it doesn\'t matter on size as there\'s no spool period, so theoretically I can just fit the biggest one I can squeeze under the bonnet and run with it (along with a ton of other stuff like uprated injectors, new ecu, 3rd fuel rail etc etc etc), but I can just fit the biggest one I can squeeze under there and just set the boost accordingly.

As for intercooler, I already have a T-II bonnet so have the correct setup to just dump one straight on with effective results. The turbo-type supercharger still do heat up because compressing air will raise the temperature of it, but not quite as dramatyically as a turbo since it\'s not exhaust driven so not heat transferral from the outlet side effecting the temps.

But yeah, setup I\'m aiming for is a Rotrex (Or any Paxton style) supercharger and intercooler in the standard place with uprated fuelling, intercooler and a rebuild on PP\'s, should make for an interesting EGI! :Laugh

centrifugal superchargers (i.e. Rotrex) are basically belt driven turbos and have the same boost delivery, i.e. it gradually increases. obviously there\'s no boost threshold so you get positive boost quicker than a turbo, but compared to a roots or twin screw which will delivery full boost near instantaneously.

you want one of these babies!

whipple twin screw!

Lacey if your running pps then you won\'t need a third fuel rail as your throttle bodies should have the 2 injector holes each. So you can run 2x550 and 2x1680 injectors or which ever you fancy.

I have seen carls TB and they\'re prety awesome, I\'m sure if you rang him he would send you a picture of them, so you would know what your looking at for setup. You could do it through an apexi ecu too.
