I believe the following quote explains it better than I can. "Unfortunately, the RENESIS used by RX-8 is normally aspirated only. It displaces the same as RX-7, that is, twin rotors with a total displacement of 1308 cc. Because a rotor chamber combusts once every revolution, compare with piston engine’s once every 2 revolutions, its effective displacement is actually 2616 cc by the norm of piston engines. The RX-7 with twin-turbochargers generated 280 hp in its final phase of development. Without any forced induction, the RX-8 can still achieve 250 hp (240 hp for European version), very good for a 2.6-litre engine. Its power curve is peaky though - maximum power occurs at 8500rpm. The turbine-like engine can spin to a genuine 9000rpm, no joking. "

500hp/ (7.5* 3.6)= Mep is 18.51 Hrm. Well, like Fyrce said, a modern F1 engine makes 850hp out of 3 liters at 19,000 rpm, and its MEP is only 14.91.... so somehow, I really think getting a MEP of 18.51 is completely out of the question. But maybe they bored it bigger you say! Alright, lets do it with different displacements: 500hp / (3.8 liters * 7.5 redline)= 17.54 Hrm. Nope. Even with 3.8 liters it'd be impossible. 500hp / (4 liters *7.5k redline)= 16.4 redline Closer, but still a no go. What if we raised the redline to 8.5k? Could it then be possible? 500hp (4liters * 8.5k redline)= 14.7. Hrm, its definitely possible on paper, but its still bests the MEP of most Moto GPs, and the McLaren F1, so I'd still say its not bloody likely. Let's reverse engineer what we'd need for an h6 with a mep of about 14 that makes 500hp. Well... an engine that has a mep of 14, and makes 500hp with a redline of 8.5k would need a displacement of : 4.2 liters. You can doublecheck my math if you'd like. That's .9 liters over the stock displacement, or 27% increase in displacement. Possible? Hrm..sure... but I'll put my money on not bloodly likely. Okay, well lets pretend it has a displacement of 3.6 liters.... what redline would it need? About 9,900rpms. Again, not bloody likely. So once again, we have you being ignorant of reality. Quote:

420hp / (8.2k redline * 3.6 liters) = Mep of 14.22 so yes, that is ENTIRELY possible. But 500hp? 500hp / (8.2k redline * 3.6 liters)= Mep of 16.937. Hrm. Uh, no that isn't possible. Maybe they raised the redline, perhaps? 500hp/ (9k redline * 3.6 liters)= Mep of 15.4 See, its still over 15. That isn't really possible. An F1 engine is 14.9, so you think the porsche engine can really do 15.4?! No way jose. Higher redline: 500hp/ (10k *3.6)= Mep of 13.8. Entirely believable. That's definitely possible. A porsche engine spinning 10,000 rpms making 500hp, with a 3.6 liter displacement. HOWEVER, I strongly disagree with your next statement. Quote:
450hp / (7.5k redline * 3.3 liters) = MEP OF 18.18!!!!! NO WAY, NO HOW, NO CHANCE. EVER. In order to make 450hp out of 3.3 liters, and a reasonable Mep (of around 14), you'd need a redline of 9,740 RPMS!!!!!!!!!!!!! So yeah, BULL-**** my friend. Say it with me. Once again, you are ignorant of facts and the real world here. Quote:

350 cubic inches= 5.737 liters. 562hp / (5.737 * 8) = mep of 12.24. Like I said last time, getting 500hp from a 350 small block is ENTIRELY BELIEVABLE. I have no problem with that. What ISNT believable is getting 500hp from a 3.3 liter H6 engine. Maybe an indy car engine, sure. But not an SVX engine, it is just IMPOSSIBLE. [B][QUOTE]actualy don't seing as a 3.9 displacement for a 13b rotary is what you came up with i don't trust your math or "knowledge".. [B][QUOTE] Fine, go ahead and fit right into that 'ignorant' catergory and ignore FACTS and TRUTH. When I calculated the MEP for a rotary, I was wrong in its displacement, and I KNEW something was wrong. I was admitting something wasn't right. I posted it in hopes that someone could see my mistake, and I could learn from it. I did. But as for the rest of these calculations, I stand by them. It's simple algebra, and although it isn't EXACT, it does give you a pretty good 'estimate' of whats possible, and what ISNT possible. Quote:

Andy hold my spot i got to go to night school i'll be back here with some more peanuts, popcorn, and might even bring a "thirsty" pack cause this looks like it's going to be a long ball game.

Also, I'd like to point out that Formula One engines are NOT the most highly tuned in the world. They are tuned for a specific purpose, and that purpose is NOT maximum horsepower or even maximum torque. They are tuned to deliver power in the most controllable way possible by the driver, to keep the chassis at the utmost limit of grip the entire way around the track. Part of that process is keeping just enough power at the wheels, but not too much. A car that is too torquey in the midrange will roast tires and overcome the grip of the vehicle in the corners, which makes the car much more difficult to drive.
I have no question whatsoever that a tuned motor in a Porsche touring car could have a higher MEP than a Formula One motor. Formula One is NOT the "holy grail" of engine technology. Maybe in the '80s, but not anymore, sorry. There's just too much regulation in the series now, and the focus is much more on chassis technology. Motors push the car, but reliability and chassis dynamics win races. The MEP principle is also thrown off severely by some of the new racing fuels being used, i.e. 120+ octane oxygenated race fuels and the like. Ultra-high ignition energy and 35+ degrees of timing advance on 15:1 compression can make some serious power. Basically, if you can build the cylinder to hold enough pressure, you can turn any kind of forces you want out of a motor. The materials by necessity get expensive and exotic, but the results justify the means. Besides, PFP is a better theory tool for measuring cylinder pressure than MEP anyway, it is more significant in terms of what is actually happening to the gases in the cylinder.
