I think your onto something there PD. A .75 (Real big) turbo will make more power at 15PSI than a .28 (smallish) turbo at 27PSI.

Haha, I actually had a guy want to trade me a GT37r for my old 50trim. Though I will never (I believe) push 700+whp so I decided not to. Besides, I would never go back to a journal bearing turbo.

Something similar, though dealing more with naturally aspirated engines. It does give some good information for realistic comparisons of engines though.

Out of all that technical info, I pulled this out of that thread, just thought it was impressive..... "On the basis of the ratio of BHP to displacement, one might argue that the Formula One engine is vastly superior (315 BHP per liter versus 140 BHP per liter). However, given the design latitude, which allows the Formula One engine to operate well at 20,000 RPM, perhaps there are better criteria by which to compare these engines."

Back before the rules changes, some of the Hondas were using a "Push to pass" system that enabled the driver to bump the rev limit in the engine up to 20,200rpm to stretch a bit more when passing in higher gears. They occasionally had reliability issues, but that's impressive for a V8 engine.

And all with no power adders. Right now they're all required to be n/a 2.5L V8's with a, 18,000rpm rev limit. The best engines are making somewhere around high 700's for horsepower.

The FIA has made it firm now, that starting for 2014 they're going to 1.6L turbo 6 cylinders. Ford is looking to reenter now(not a surprise with the success and performance of the Ecoboost). GM has also submitted an engine design proposal to the FIA, and Honda and Toyota are looking to reenter as well.
