What rotary experts think of this kind of setup to use on Renesis. Will it give best of two worlds - fastest spool up and good top end? May be even GT25?

This subject has come up before.

Going to be a lot more money, and more expensive. Not to mention twice the amount of parts to break, and that would be interesting fitting that in an Rx-8 bay

 

It would be sweet. But the last gen RX7 FD has twin sequential turbos (like the setup you're talkin about) and they had a whole host of vacuum issues associated with them. Considering most people in FD circles worship the single turbo mod, for power AND reliabitly, I would go single.

Tudor is the guy putting the Rotary in his race car designed by his company. So it'll be for racing keep in mind. For the power the renesis is pushing, i personally dont see a need for twin turbos. It would be beneficial if you're pushing more. right now the mazsport kits are pushing around 350whp without a lot of lag with single turbo.

The renesis revs a lot higher than the 13B-REW. A good set of twins can really use all the rpm (3000-9000+). But then again, you only use the top end in racing, a good single turbo can accomplish that.

There aren't many circumstances where I can see wanting to use twins as opposed to a single turbo. I personally wouldn't do it on a Renesis.

 

Thanks for your opinion guys. Just trying to look for all possibilities to make more power without sucrifysing responce.

Renesis_8,
This car is in fact designed as a street car aiming to compete with nobles. It is track oriented but the way it is designed it should be more comfortable on the street than most exotics and after 20 minutes of simple manipulations will be much more at home on the track.

Wait are you the guy designing the car that you want the rotary installed in? If so I've been wanting to chat with you about engine design anyways.
