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. /Lasse |
God, I hope you are joking. My guess is about 250-260 hp. You'll be lucky to get to 210-220 whp.
|
Very ambitious Lasse . Aim for 300 - but if you hit 260 we will still be happy :)
Love the intake idea - can't wait to see what difference that makes . |

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.
|
Dont't forget to intall one of those ebay chips. They'll give you another 25hp
|
we all talking about rearwheel hp or flywheel hp?
|
I would guess flywheel which gives you a better chance but still, good luck dude.
|
i think he said engine hp about 20 times in the first post. whys everyone still confused?
300hp at the crank isnt unbelievable. Good Luck!! -hS |
I think it's extremely unbelievable but I applaud the effort.
|
Thank's for the inputs guys, i appreciate it! Goal is 300 flywheel hp@10 000 rpm. But it's along way to go...
/Lasse |
good luck man, hope you get as close as posible
|
he might hit it if the Nology sparks don't catch fire and burn the car down first...
|
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. Paul. |
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? |
^^ All the haters just got pwned
|
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.
|
im curious in your air horn/ ITB set up. Any pics of it?
|
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. |
300 flywheel all-motor horsepower would be awesome. Be sure to post plenty of pics and a vid!
I too am curious if he can pull it off but we should be encouraging our fellow Wankel tuner, not discouraging him. |
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 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? |
It doesn't matter if he hits the goal or not. Any research and development done for increasing power in our car benefits us all.
PS: I was being serious about the spark plug wires. |
BTW, I didn't notice on the original post, but are you porting the engine ? That might help get some hp for you on your goal to 300 hp at the crank.

That's what I'm saying! When you get the air horn setup all worked out will you be selling the setup as a kit or anything? That would be cool. And yes, I realize a purely dyno queen engine would be rather pointless other than for use in a dick measuring contest, but his development will help us along, too. Just like those 500-whp Civics- they're pointless because you can't get the power to the ground, you just spin tires. And he may have to spin the engine to 12K to extract is, making it a potentially one-time use fun gernade or shrapnel, but it's still interesting to see if he can do it. Dave |
it's not h8ting, if you've been here long enough you understand that talk is cheap, especially big talk ...
why would somebody would even post about big plans in the first place? |

Good luck to ya Lasse. Will wait in anticipation for the results of your endevor.

Lasse how's your turbo coming along? actually I've come to the opposite opinion, only because he like others insists on tuning a Renesis the same as any other rotary, such as insisting that multi-tube headers made from stainless will be the hot ticket. He's been multi-posting about making 202hp but thats on a hub dyno which is only 192 hp dynojet, 185 hp mustang. I realize it's blunt just to say it and I'm not trying to be a h8tr. Rather, I'll believe it when I see it, until then it doesn't mean much. It's telling that those here who have a reasonable grasp on the subject are sceptical. It all sounds impressive to people who aren't very informed, no surpise who's going rah-rah and who isn't. Coming up with a new intake that actually improves upon the Mazda design is worlds apart from building a turbo system. The people turning 260 are doing it with Motec engine management, IMO a Microtech is a step backwards. No mention of porting, not going to happen without it, yet it's unknown territory on getting it right. So it's not about h8ting, its about showing the final product. There's no skill or ingenuity involved with talking about it. I still get a laugh out of members thinking highly of somone who's talked big and never delivered, we have several here who fit the bill. |

I have been making 202 hp@hub and i am soon gonna bring power curves of it. I am not gonna "brag" about making 300 hp becausse it can be say "only" 280 hp. Otherwise i will try making 300 hp with a Microtech but may use a Motec when i'm first tested the the MicroTech. So now it's up to me :) /Lasse |
good luck, hope you do really well
|
yeah good luck i hope you can hit that goal
|
you could make some variable length plenums like the ones mazda used in their 4rotor racecar..that would be sweet, and you wouldnt sacrifice low end torque either......getting them to fit in an rx8, that would be interesting.

Im betting if everything is done right he will see 280+
