It was crap imo

the 4-port runs out of air at 7500 rpm, but the center housing only has dual primaryintake/siamese exhaust ports. So it likely is stalling sooner. It likely wasn’t much more than a good 6-port with a little bit torque, maybe.

An engine builder told me the 6port with the aux plugged will dyno better than the 4 port (218 peak). So even if you did it that way the dual primary intake/siamese exhaust on the center housing is still an issue. It won’t make 50% more output.

from that one picture of the engine out of the car it seems like it uses 4 port plates

 

Would make sense for a 3 rotor i suppose. But if you are looking to build a bigger engine from Renesis parts, 3 rotor seems to be the way to go. The people who built it had very good things to say about it.

the ones who don’t know what they’re talking about or are in denial. Again, the center rotor would only have two primary intake ports and two siamese exhaust ports. It won’t make any power much past 7000 rpm. It won’t be any better than a good 2-rotor 6-port. It’s a terrible idea. Wake up.



Yeah, BMI. 610 hp 4-rotor drift car, what a waste.
