Didn't the Mazda LeMans 4 rotor produce 1000HP straight motor? Now if you had the money to do a 4 rotor in the first place...couldn't you just mimick their techniques? Especially since from what I've read is they achieved that 1k HP just by upping the revs to 11k instead of 9k which was far less HP. Of course I am talking about a super mechanic team that has endless amounts of money and R&D to be able to do this.

 

I think you need to research the 787 a bit more

What I think he hints or actually wanted to say if he could type in "english". Is that Lemans racers are always placed with restrictors on the engines that limit horsepower. So without limiations could a 26b produce 1000hp?

Also what do you mean they upped the redline to 11k instead of 9k. They just don't go into the Bosch or Motec or w/e ECU and change the redline and boom 300 hp more! This isn't gran turismo. I doubt anyone would want an engine to run Lemans that produces 1000 hp (Within current LMP1/2 regulations).

All this to say, in my beleif a 3 Rotor turbo or a 4 Rotor N/A is more than any street FD should ever dream of.

1) i am a rotard, but honestly i have seen with my own two eyes a non built ls1 408 stroker w/ a big turbo and etc push over 1000hp/trq and run for a few years and also win the small block chevy with power adders class at hot rod's drag week last year, oh yea it weighs over 5000 lbs http://www.1320video.com/img/album01/67_G.jpg
so its not to take away from the lsx blocks, they are great and there are a lot of them making alot of hp


2) 23a's(12a) are shorter and lighter than a 20b, and i would love to make one some day

3) 4 rotors just sound SIIIIICK

4) screw 4 rotors, its about the 6 rotor!!!

Some people on here don't understand that.

Whenever someone start making arguments with the "I think..." statement, I stop listening.

 

here's a boosted 4-rotor ...sounds nice

bump HA HA

 

Uh, why?

 

Don't get me started on that mess! I can't get my head out of the clouds over this damn engine! I just want it freggin' gone! You all bring up one singular point and that is... MAZDA DIDN'T GIVE A FLYING MONKEY'S *** ABOUT THE R26B! They themselves found it too much of a hassle to make a 4 rotor engine in production!They figured out that no one needs 4 damn rotors to make a happy 1,000 HP and up, they wanted to crank 400 on the 10A but they didn't. Damn... It doesn't stop me from saying that a ridiculously powerful 4 rotor street machine will look better than a Viper or Vette any day because WE rotor nuts have class and a lot of *****. That's right, one of us will actually do it and there ain't nuthin' anyone of us will do about it but nod in bewilderment.

 

Wow, it's the week of ancient threads.

 

seriously we need to be supporting this for the guy. im sure that there will be some if not a lot of problems till he gets this right. but this is our chance to match the BIG v8 swap guys with a rotary. I just think that there will be a quite a few bearings needed and the rpms not much higher than 9k considering the e-shaft is probably about as long as buicks fireball inline 8. just my opinion

 

i'm assuming this is a short block....

as i doubt they are also including custom manifolds and such...

 

Zombie thread

 

of course they can...as long as the engine isnt making substantially less torque up higher in the RPM range- it goes without saying it will make more power if it revs higher..

you know..power = torque x rpm blah blah blah...
increase rpm, and dont decrease torque and you have more power, simple!
increase rpm, and decrease torque slightly - you will still have more power!

EDIT- adding some real facts:
FYI - horsepower forumula/equation is Torque x RPM divided by 5252 = power/horsepower!

so just for argument sake lets say it has 400 ft/lb of torque @ 9k rpm. that equals 685hp.
lets increase that RPM to 11k and keep the same 400ft/lb of torque - suddenly we have 837.77 horsepower!

Even if we decrease torque to 350ft/lb at 11k rpm and we are still making more power ! 733.05 horsepower

 

wow, I made this thread...

 

does anyone have a dyno torque curve of what a 4rotor engine will do?

 

Is a 100 gallon fuel tank included with a 4-rotor engine?

 

No need, mine uses less fuel then my 13B BP turbo engine 4rotor used about 5 liters of fuel pr 10km on track.

That's about 2 gallon pr mile , the 13b used about 3.1 gallon to the mile

 

Lol just noticed the thread was quite old :P

Even before my 4 rotor build :P

 

what kinda power are you getting out of your 4 rotor, I just saw a vid of madmikes 4rotor and its getting near 600hp but only like 300 ft/lbs of torque.

 

I'm not sure I who could justify that as a cost effective option for 650hp

 

hmmmm thats weird.. his old dyno on the ppfe had some 510ish with close to 505tq...wonder what could've changed that much?

 

idk, I saw on a youtube video of driver talking about how they are trying to get more torque out of it as they are only getting ~300 even though they were getting over 600 hp.

 

Custom tension bolts aren't worth the money, get a dozen of these and you'll be fine
