Judd (Who Cares?)
Judd has been the top engine available to non works teams in LMP1 for a number of years.
Is it fair that purpose built racing engines have effectively been handicapped just so other manufactures like GM can enter LMP1? The thought of a 7L GM LMP1 car is fantastic but as the ACO start looking into the comparison between homogulated and non-homogulated engines, who will be fighting in Judds corner,for a fair balance? |

Who's to say Acura's P1 won't be a race engine?

They had to address the petrol/diesel issue , cuz folk were getting cheesed off with it . Supposedly they will adjust the rules come next year .
Maybe partly due to Acura , and other manufacturer interest , and also to do with privateers who dont stand a chance with an off the shelf engine . Acura are talking about LMP1 for 2009 ..... I have a feeling thats why Montagny was recruited , for an LMP1 campaign , with his presant experiance of the best car in the field . Welcome to 10 10ths BRG ..... it gets mad around here sometimes !!! Last edited by The Badger; 18 Jul 2008 at 00:25. |

What would Acura use other than a brand new designed for racing engine? They don't have anything sitting around in the realm or the C6.R or DBR9 engines, as far as I can tell. Might be smart for them to run something next year, if even just to get the ACO looking at how to equalize their engine with the GT1s and the purpose built like the AERs and Judds.
Another Judd question though, whatever happened to their diesel V10 engine plan? Saw something about it around a year ago and then nothing. I'm guessing it's a technical achievement beyond the scope of a small engine builder. |

Judd makes great engines, just about two years behind every other engine developer. |

As well as homologated GT1 engines, the ACO are allowing production engines of any size, according to Racecar Engineering.

I thought 7L was the cap for production engines ?
Who makes a bigger engine that could be usefull for LMP ? |

Im just wondering cuz the original rumour was a 7L cap ..... so why have they decided to let "any size" in ?
Who has a bigger than 7L thats useful for LMP is my question , not that you need one . |

Shadow used an 8.2 liter Chevrolet V8 in the DN4, but that was over 30 years ago, and aluminum 7.0/427 GM big block V8s that such monsters were created from aren't mass produced anymore-though it's torque should come close to what the Audi R10 and the Peugeot 908's 5.5 V12 diesels have.

Common misconception. An all aluminum LS1 engine(I Know, it's only a 5.7l) weighs less than most iron 4 cylinders.

Warhawk - Crank Clearance: Accepts 4.250" stroke crank (454 c.i.d @ max bore) http://www.worldcastings.com/catalog/15.pdf World Products has also released its "Warhawk LS7X" 12-degree cylinder heads. (The company also has more street-friendly "Warhawk LS1X" 15-degree heads available that'll work on any Gen III or Gen IV engine block, see the Web site for more info on those.) We'll get into the features of the LS7X heads as well as some of the more important differences between the Warhawk and GM blocks in the photo captions, but here's a discussion of some technical highlights of the LS7X block that will blow you away. and how about this: 8.3L 505 c.i. 90* V10 700 BHP @ 6,300 RPM Torque: 650 ft lb @ 4,800 RPM http://www.ilmor.com/710.html The above. hmmm could we see this in an Accura P1 car? |

There are plenty of 4l+ super/turbo charged road car engines.
The old Sauber Mercerdes 5l V8 was lightly turbocharged, big power, low revs and reliable. Bigger capacity production turbo engines could be the way to go if you want to reduce costs. Last edited by JAG; 18 Jul 2008 at 19:32. |

I have a feeling, with the launch of the DB, that Judd might be trying to concentrate more on LMP2 engines than LMP1, as they are likely to stand more of a chance in the LMP2s.

Obviously the 7 liter mark is due to GM. But I must admit, I also feel a bit sorry for John Judd and his team. they should be able to run less restricted, I know that the general ACO idea is to cut cost on developing purposebuildt raceengines, but the result they have ended up with at the ACO, is that AMR is using their production engines, and the Judd engines are not competitive in the same way. I would feel ridiculed. |

However, the ACO are looking at the power output differential between Race and Production engines as well as looking to maintain the gap between P1 and P2 (ie pegging the Porsches back) and the Diesel inequality. The times have surpassed the 3:30 mark by some way during the race and the ACO will be using that as the benchmark. Whilst I know its not just engine power that produces quick times obviously the Aero packages will be very infuential. But the engines are the main piece!

Well, I have no idea whether allwayswatching is right..
But, if it is so. Then I guess that the block would be heavier than current engines? How about direct fuel injection, will it be in the cards soon for the Judd? Dont get me wrong, I really like John Judd and his whitecollared guys. But without proper funding, they will be up for a hard time. |
