Twin turbo idea
 
So I was driving around thinking about random shit and I was wondering there are these motorcycle turbos that have a 25mm exhaust inlet for the turbine and I was wondering what the exhaust header tube inner diameter would be? I was thinking of running two side by side they are good for small engines up to 1000cc each at 10psi reliable but I've also read exhaust temperature is hot coming from rotary engines and the high rev too would my idea be worth trying and the turbo is a IHI RHB31

Lots of thinking you have done while excluding much needed punctuation.

just no. they are too small even if you had 8 of them.

Just pointing out the fact that your lack of legible sentence structure makes it hard for most people to even understand what you are trying to relay :)

Have you tried to even search this forum? This topic has been discussed in many threads in one way or another.

the exhaust port at the engine flange is roughly 48mm its a little wider than it is tall because its not quite a circle although its close enough that we can say that its 48mm so a 25mm turbo will be way way way too small in fact i think you would need about 3 of them per rotor because the turbo is good for 1,000cc and the rotary has three 654cc chambers per rotor, imagine the manifold for that!

Hmm, makes me think one could pretty much strap a t25 of some description to each exhaust port with a bit of port matching... unless it just works out cheaper to get an EFR.

Ps, the lack of punctuation was negligible and any trouble a certain asshole had reading that is his problem.

its been done, it was kind of a fad in Japan about 17 years ago. they were using primarily GT3037's, which are T3 sized. its a 600ps setup.

its also expensive (2x turbos, down pipes, oil lines, etc), and plumbing is a challenge.
