I was asking about the tranny setup because I've heard that the Wankel delivers its torque at higher RPMs than a 4-stroke. I was curious how you were planning to address that issue and the additional issue of the Wankel's ability to deliver HP at very high revs. I didn't know that a G50 had gears suitable for the Wankel application, and that's good to hear.
I'll find out in a few weeks when my friend is done breaking in his ~700 hp 3-rotor '74 911. Widebody, and loaded with modern 911 goodies...all business.
Fwiw, three rotors have moderatley flat torque curve. They are also a 4-stroke engine. I've posted this before but here is a dyno graph of a moderately built 3 rotor on pump gas.
The hard part - and I don't mean to minimize this - is that finding pounds to save very quickly becomes hard and expensive, i.e. really expensive.
"Adding" lightness to cars "adds" lightness to your wallet. Three aluminum side housings from racing beat (saving 45 lbs.) is about $4500-$5500 depending on desired specs.
Finally, Dave I believe your quantity and quality of your research deserves a reward, and I've taken it on myself to award you this ultimate adornment of the rotary minded:
I'll wear it with pride every time I log onto this site :dunce:
Frankly, I don't know how much more than 500hp can be reasonably utilized in a 2000 - 2200 lb car.
4 to 1 power to weight ratios 500hp/2000lbs in a road race car is about all most people can handle. I don't want to offend but 2 to 1... or less???? get real.
That is the nice thing about turbocharged cars. Besides using your right foot, you can control the boost to limit or maximize your power very easy to meet specific needs/goals. Regardless of what engine I chose, it would have been turbocharged. Hooked on boost :drunk:
There's a good many guys running 3:1 on the street, and figure an SLC loaded with goodies would weigh in at ~2500lbs at least.
My goal is 3:1 (2400-2500 lbs / 800-850 hp) on pump gas with a/c, stereo, sound deadening and full interior. If that proves to be too much power, as said before, I'll just lower the boost (i.e. power) with the push of a button
Maybe a bit of traction control, as well.
Those work very well but do have their limitations. The big hp Supra guys know this and it's because the power curve (as shown above i EFN's post) make so much power so fast that the TC is overwhelmed. They may have been improved as my info/experience with them is about 3-4 years old. I do know quite a few RX-7 owners who use(d) them with great success.
There are also standalone ecu's with built in TC but I doubt any of the LS guys would need it :tongue3:
