GT1 engine homologation for LMP1 rule question.
Since GT1 engines are allowed to be used in LMP1 cars on equal par with purpose built engines now, I have a question.
Does displacement count, as the 7.0 V8 used in the Corvettes is approved, but is 1 liter over the LMP1 limit? And could one dust off a Panoz Elan V8 and use it a LMP1 car under this rule, as it's basically the same engine as the Ford V8 used in the Saleen S7 aside from displacement(6 vs 7 liters) and some details, namely the air box? What is the criteria that the ACO is using aside from a production limit? |

So, the way I read that, if you have an 8 litre GT1 engine, it's pukka in LMP1?
So long as you made 1000 models per annum... So, when do Chevvy wake up to THAT one? |

assuming I read your statement and the regs before it, wouldn't chevy have to cut the engine back to 6L, as in smaller than the Z06 motor to be an LMP1 engine? I would love to see them in protos but think they will go the smaller turbo route with it advertised as an Ecotec engine possibly derived from a future Ecotec project for a street car.

The chevy LS 1 & LS6 is 5.7 L, the new LS2 is 6 L and the LS3 is 6.2 L while the LS 7 is 7 L and there might be a 6 L V10 in the engine developers ware house that could be re activated. But then again that could be a mear rummor too. So there are several corvette engines sizes to work with |

So I guess that this leaves Panoz/Saleen/Ford out unless one uses the 5.4 liter version of the Ford 5.0 Modular "cammer" DOHC V8 used in the Esperante, which isn't poweriful enough, and is larger and heavier than the 6.0 Elan 6L8 V8 that's basically an aluminum block/fuel injected Ford 351 SVO Cleveor.

IF GM ( Chevy or Caddie badge) decide to RE ENTER LMP1, I am sure they and their engine builder partner will come up with an appropriate engine.
alternative fuel E85 maybe? of heck with it just put in the Duramax Diesel with a few HP modifires. The available Duramax Diesel 6.6L V8 Turbo engine features:
I have this in my pick up. Does a darn fine job of hauling the race trailer. |

Definitely Not. He tried to achieve too much...particularly relating to COG...with too little cash. I believe that the car had immense potential but it was not to be. He did have the foresight though.
A full blown GM effort would entirely different. |

I will preface this with; this thread is about homologated GT-1 engines being utilized as P-1 engines. That being said; If GM decided to go down the diesel path (highly possible) they would not use the 6.6L out of your P/U. Once again it is rumored that the Tonawanda plants future engine programs have been put on the chopping block. This is where the new Duramax HO line was to be developed for GM which was rumored to include both a 4.5L HO and 5.5L HO V8 in the program. I would have thought that if they decided to go diesel they would have/will choose the 5.5L HO V8 as their weapon of choice but.... L.P. Last edited by HORNDAWG; 22 Mar 2008 at 17:19. |

Lister tried to use the 5.7/6.0 LS1 or LS2(or de-bored LS7) in a modified Pescarolo 01 chassis in '07, but Lister ran short of funding, and the car was put on the back burner, and with Lister on indefinite hiatus(they basically shut down), the car might never see the light of day.
As for the basic rule, I emailed Mulsanne Mike about it, and he said that from the wording of the ACO regulations that any engine(regardless of original capacity as long as it meets the 6 liter max in the racing version) that meets production requirements can be used-including the Elan 6L8 and a de-bored/de-stroked Saleen 7.0 V8, as they share the same block, heads, and many internal parts. IE, if there's a 1000 Ford/Saleen/Elan V8s, a 6 liter version should qualify under the ACO's rules. |

The rising prices of grains, all grains due to the farmers riding the ethanol band-wagon, has made the base fuel component too expensive,and they cannot see a time-scale where it will drop down to affordable levels in the near future. It's great, thei are cutting off their noses to spite their faces, gotta love it. Bob |

I'd like to know what assumptions they are making in that. Theres is a lot of BS fying around both ways on the whole biofuel issue, and a lot of misinfomation is being spread by the environmental movement given the threat that a technological solution poses to their power and influence. Besides, if the coskata method isn't up to much then theres always this: http://en.wikipedia.org/wiki/Algae_fuel |

Another part of the article is about how great switch-grass is, according to a scientist at the U of Minn., after which they go down the hall to the depart that deal with economic realities and blows the switch-grass band-wagon apart. It is simple to do tens, or hundreds, of gallons in a lab., when it comes to millions of gallons, the economics change, DRASTICALLY. |

Coskata's method uses plastic, rubber and biological waste (the kind of stuff that would end up in landfill) to make biofuel. They just need to get more municipal waste and cellulosic sources in there. Last edited by johntt; 24 Mar 2008 at 10:37. |
