Norwegian 4 rotor beeing built på WGT

[SmbFD3S]

Looks amazing mate, always wanted to, and still hope to one day, build a 4 rotor
 
Hope all goes well with it and look forward to reading the progress :D

[jantore]

I am hoping to get near 550 at the fly with a 3 rotor:InLove
 

 
Pip was saying you wanted 700 fly wheel horsepower from it
 
I will be at WGT for that and at Oulton for your trackday!

600rwhp is about 670 or so at the flywheel. So 700 will probably not be a problem. But we won\'t push it to max. I want it to last for a while. So if we need to push it to get 700 we might do it on the dyno and then just take off some HP to make it safe.

But with pips tuning of the 3 rotors he\'s done i think it\'s posible.

looks great,  i wouldnt want your fuel bill though !  Do you have any more detail on the gearbox,  there are a lot of people who have high HP road/track cars here and keep breaking the rx7 box.   I assume yours is a circuit car?

So do I JT, will be good to see it when its done

hmm thats a tall order my friend even though its PP, the most I\'ve seen personally and read about is a two rotor making PP making 300 fly.
My estimate will be 450 fly for a 3 rotor PP, but all depends how high you going to rev it I suppose.
Fingers crossed for ya.

Pip Stopped tuning a 3 rotor PP RX8 @ 375 RWHP or 450 FWHP!
 
Thinks mine will make about 500 at the fly but as you say down to revs

I do belive the 3 rotor PP engine for the Belgium Mazda Race Team did somewhere around 470 at the wheels. That is arround 626rwhp on a 4 rotor. So only time will tell.

It did with 9k revs, made 435 with 8k revs

Wouldnt this be too nose heavy for a race car?

Maybe a stupid question but why build 3 and 4 rotor cars when you can get near enough the same power (if not more) with 2 rotors and a big well set up turbo system? :confused:
Very impressive though and would love to hear it on the track when its done

Because we can!
 
And the noise!

Guess one time why im building a 4 rotor system.


Edit:

It\'s quite simple why im building my 4 rotor. Cause it\'s NA, it\'s a 4 rotor and the noise

I have had way to much problems with turbo\'s so im gonna go for this now. And cause not many have done it. And im aiming for 51/49 ratio for weight.

The engine has been moved back about 15cm so that moves alot of weight back. And the car was more heavy in the rear before. So some more weight in the front is ok. And besides i have removed the turbo and intercooler as well.

IIRC Bill Shiells in NZ made 298 at the fly with a 13B PP back in the early 80s. Things have moved on a lot since then. BP\'s are cracking 300 downunder these days.

JT why didn\'t you get green bros to build the motor? Their porting is awesome and they have built some really quick n/a cars.
