ok, peripheral inatke is the best bang for your buck, correct. downside is high idle and loudness.

what would be the advantages of an intake like this?

is there a lot of work involved?

are there any companies that would tackle such job?

thanks



heres the intake work im talking about.

Hey thats a pretty cool pic. So for the exhaust would you still be able to use the stock openings or would you have to make them out the side housings? Doesn't the Renesis push the the exhaust out of the front and rear housings instead of the rotor housings?

intake and exhaust

Wheres a translator when you eed one...



Did you see them ****** intake ports...dam

DAMN thats cool! The peripheral and exhaust ports seem so close together though.

PP gives you very little bottom end (Power is from 3-4K and up)



There is so much overlap it's like having a HUGE Racing cam in a Piston motor. I think can also be problems with reversion, where the air flow (and fuel are pushed out the intake ports).



But PP's make great power. 250 HP for a 13B N/A is comon.

my guess is, plus ive been told, but not from anyone whio has actually done it. thats why you keep the center ports. gives you a little better low end. but i could be wrong.

I'm not sure why the center ports are being used here... kinda interesting, I haven't ever seen that. I don't see it adding any low end unless you are keeping the PP's closed somehow. You could maybe recover some low end if you put some PP butterflys low (close to the engine) in the manifold. Kinda like the Toyota TVIS system. That's exactly what they did.



A PP probably wouldn't be great for a daily driver... unless you have a 6:1 rear end with the stock Mazda gearing... and drove just a few miles.



Because you'd want to be in the upper RPM range all the time and couldn't afford to drive it more than a couple of miles.

Wow I didn't see the pics before... Those ARE some HUGE ports!

PP rocks. i'd love to have a PP turbo https://www.nopistons.com/forums/pub...#>/biggrin.png
