hey just wanna know if the renesis rotors can be used in the 3 rotor? i seen them use it in a stock 3rd gen and got 22hp gain
|
Yes there are a couple already out there I believe.
|
|
i dont find 22hp too farfetched...... considering 1psi of boost can sometimes yeild 20hp.... so an 11% increase in compression ratio should make more right?
i wonder what modifications need to be done to the rotors so they can be used for a peripheral exhaust 13b. im sure there are slight variences on the renesis rotor for them to work on the sideported exhaust |
|
If you were going turbo, I'd think you would want to machine the apex seal groves to accept a stock 3rd gen 2mm seal. The rx8 seals are shorter, and are thus weaker.
|
Aren't Renny rotors high-comp though? Wouldn't that make turboing a bit harder?

But do they allow as much air to be forced in as lower comp rotors?
|
well.... save volume.. the engine is still called 13b isnt it?
|
High compression = more likelyhood of detination at the same boost level as a lower compression rotor.
it should make some more power though |

Yep so if i get a 20B for my 1st gen since its sugh a light car i wont mind having a all N/A engine 3 renesis rotors with a custom lighten E-shaft from guru racing, custom lighten pullys, electronic distributer, custom intake manifold from magnus that clames 40hp, and a exhaust to match the power and so on i say ill spend 12G on everything and get a 300hp+ reliable, efficent motor....what you think

how do the counter wieghts differ from a 3 rotor to a 2 rotor? are there more than 2?
|
ok, i did a research.... s5 are 9.7:1 and s4 are 9.4:1

so no one cares about an efficent reliable, 20B pushing 300hp?? with lighter internals and pullys that thing ill get to max HP in no time better than a F1 hopefully
|
of course people care about reliability..... but im sure cost comes into effect sometime

If i don't get 500 whp on my 20b single turbo i'll be disappointed
|
i'd be too, i'm doing that on a 13b pretty easily...
|
i'm aiming for 600rwhp at less than 15psi......hopefully reliably. 500 should be an easy task depending on the turbo.
|
600hp and reliable in the same sentence?
|
i'm gonna DD that bitch too!

don't really know...
