All out stock block Renesis.
That's what i'm intend to dyno early this spring. I have a stock low mileage 20 000 km Renesis engine and some ideas to extract 300 hp from the engine. Modification and parts list will be as follows:
Microtech LX-10 fuel/ignition system with Bosch coils.
Underdrive pulleys,
Electric water pump.
Nology spark plug cables.
ML Wankeltrim made stainless header.
Feritta race cat w/ single rear silencer.
New aluminium intake manifold w/6 butterflies.
6 full radiused air horns and cold air box.
This is the most of the set up but more is to come on the way.
To tune the engine we have 3 different headers and 3 set of air horns with different length.
The engine shall be dyno'ed on a SuperFlow engine bench that is carefully calibrated by"DR Ernie" turbo guru in Sweden. If we achieve the goal of 300 hp the engine is for sale. I will write occasionally how the project is going.

While I am curious to see what you can get out of the engine, I'd have to say that 300 hp naturally aspirated is all but unattainable. I just don't see that happening unless you rev it up over 13,000 rpm or more and design everything around that goal.

If you are serious, it will be quite interesting to see how far you get. You need to add ceramic seals to your list if you are seeking the most up top possible since they can seal better in that range with the right spring pressure beneath them and can allow slightly leaner tune with more ignition advance.
I wish you success.

some of you apparently dont know(the ones making comments about ebay chips) about Lasse Wankel. search his posts (starting here https://www.rx8club.com/showthread.p...6&page=4&pp=15 ) Hes been working with rotaries for 20+ years and has built headers and exhaust for the renesis for his 8. as you can see from the link above he even understands the need for proper flow testing. so he's not jsut one of these blowhard kids that come on once in a while with big ideas- he knows what he's doing.
not that that means he knows everything
for instance he should definetly look into those apex seals MazMart mentioned for better sealing at those higher rpms- it wont be a "stock" block at that point i think- but to get those high NA numbers its necessary.
Lasse how's your turbo coming along?

I wouldn't say anyone is hating. Just very skeptical about 300hp. That doesn't mean that everyone wouldn't still like to see an all out attempt on what the engine can do. Basically 300 hp at the crank would have to be somewhere around 260-265 rwhp or so.

and i wasnt "owning" just trying to explain for the folks who were being more than skeptical.
rg - the extra rpm needed to reach 300hp would increase the losses a small amount. you would probably be looking at 250-255 whp. its irellevant anyway in the case of his goal since he's just going for BHP on an engine dyno.

If he revs it up high enough with a short intake manifold, he might get up there pretty far. Total airflow through the ports (they are pretty big) as well as rpm limit before self destruction will be the 2 big concerns. People watching this thread need to keep in mind that merely hitting a number for the sake of hitting it and having a wide drivable powerband at that power level are 2 totally different things. I wouldn't ever expect to see it be anywhere near that powerful as an engine that is perfect for a street car.

I too am curious if he can pull it off but we should be encouraging our fellow Wankel tuner, not discouraging him.

I bet that sucker will sound mean. Probably not too practical for street use though I would assume. What do you think?
I'm thinking one of the factors might be the lack of air filter(s). If that didn't pose too much of a problem I could see it being practical as long as power in any part of the band didn't decrease from stock. What else am I missing?
