Here is my RX8.
We have been trying to extract as much power as possible from the Renesis engine without the use of forced indutction.
So far we have done 6 engines types with various types of porting and this is a vid of our latest which is fully bridgeported.

Power is unknown on this engine as yet but we have had 254hp flywheel with a previous engine. Most I have ever seen from stock engine is 219 hp.
Midrange power feels so much stronger.
We warranty our rebuilt engines for Detonation, track day\'s and RWYB and NOW for 30 months which is two and half years or 30,000 miles
We also build all types of race or road engines.
We build race and track cars too.
Any kind of porting undertaken.
Single turbo conversions.

It\'ll be interesting to see more on this and see if you can get anywhere near the power of a turbo or supercharger.

Carl needs to push the boy dries of the 4 port too lol.
Those figures are impressive
I remember reading an article that Amemiya was claiming these king of figures from a porting job and their ReDom map. But their claims where wheel HP so it seems that the UK is moving in the right direction

Congratulations with this Carl look forward to seeing the figures

I\'m guessing there\'s no chance of seeing the ports?

Is this with standard rotors and e shaft? No lightened internals

Also what does it rev up to?

I rev to 9500 rpm with this.
The rotors and E shaft are stock but we have done some trick things with the seals too.
All of the inlet ports are bridgeported with the rotor housings matched to the bridges.
Fueling and intake have two mods which I am not prepared to give away.
We have built quite a few ported engines for customers now but this one is the most extreme I have done in my car as yet.
If you want to see what it is like I am happy to take anyone out in the car.

I am not keen on showing the ports as yet due to other tuners wanting to do as we have done.

If you are prepared to have your engine rebuilt again ( for a large fee:Giggle) I can really go to town on the porting we have already done for you.:mmmm

All Mazda rotary engines have side inlet ports so the work is similar to previous engines but also has to take into account the different positons of the seals in the Renesis engine.
Having done a Renesis triple in the past I am now working on a Renesis Quad.

I have been planning it for ages. We learnt alot from the one we did for Pete Barber and have also learnt alot about porting these engines now.
Time to put it all into practice for the road.

We can speak of further things once my warranty for the current rebuild is up lol.

still happy with what i got but some bridging would be nice... (even though at the time you refused)
