Most sequential racing boxes use the clutch only to take off in 1st gear, after which you just slam the gearlever around, no need to pop the clutch.

911 GT2: 505ft-lb, 3.6L -> 140ft-lb/L Evo X: 300ft-lb (?), 2L -> 150ft-lb/L etc. If you meant, normally aspirated? We would need to know the specific output of all the good production-based racing engines out there. Of course a NA street engine will never have the specific output of a NA racing engine. Duh. |

I obviously I mean N/A. "Duh." But thanks for correcting the mistake without being a prick about it. Quote:
Can anyone find any N/A engine making over 92 ft-lb/L? I'm really curious. Just throw a URL out if you have one. Quote:

No prickiness intended - I was simply astonished that someone could make such a definitive and sweeping statement...
Quote:
Although if there is a HP limit in the GT2 class, that could mean that larger displacement engines (F430, Aston etc.) may have to limit their torque output in order to obey the HP limit. Not that a few points in either direction is really meaningful for racing, IMO. Winning races seems to be a delicate balance between power, weight, handling and fuel consumption/management. Oh, and driver. Quote:
As you well know, street engines - no matter how good they are - have to cope with emmission regulations, noise regulations, reliability considerations, low grade fuels etc. IMO they're not really comparable with race engines, in any way. Anyway, this looks like a promising platform. I'd particularly like to see how they managed to have those radiator ducts in the nose, so close to the windshield - they must have pushed the engine way back towards the bulkhead. I wish they'd make an M6 race car for the GT1 class... |

So, can you point me to any tuned street engine - any at all - making over 92 ft-lb/L? And of course I should love to see race engines with similar figures also. A dyno graph would be even better. |

485bhp at what RPM? 125nm/L for a NA engine is certainly impressive
This car has more scoops and vents than I remember seeing on other GT2 class racers... probably the result of their R&D in CFD and wind tunnel through their F1 programs. |

Remove the fins, and cover up the lower two air dams and you will have one aggressive looking street M3 without being way too rude. They should have incorporated those front fenders and rear wheel wells on the new M3.... man... I can see some of you doing this conversion soon. BTW, Can a 335i with Vishnu V2 smoke this by the bus length? |
