New LMP2 engine - and (more) rule changes

[ss_collins]

hmmm.....I'll believe it when I see it

I was told the same by one of the WR engineers.

sam's having a pretty long sleep!

yup I was then the forum seemed to be down - then I was on a plane - then I was asleep but now... I'm back. Heres a pic. Actually this engine should be reliable and produce good power - it has some issues - stiffness is a question, pistons and rods have not been chosen yet, cost will be based on leasing engines, it weighs a little more than some other LMP2 lumps at 140kg - but I'm told by an engine guru (Ian Bamsey) that the Zytek is a similar weight.

This is the first of a number of new engins - Ferrari could well be next - question is - what chassis is going into and will it be painted red?

Looks great!
Is that a standard block though? I'm not that familiar with the BMW V8.

looks very nice, I dont think stiffness will be an issue, I have seen several production based V engines successfully converted to fully stressed race operation in single seaters, the Infiniti pro series V8 and Nissan V6 are prime examples, as long as the sump to block interface is properly dowelled it will be fine......anyhowm in a sports car installation, most are semi stressed, via using A-frames, in order to transmit the bending loads into the side walls of the chassis.......as Mr Elleray was saying on the embassy thread

[ss_collins]

Indeed - Mike Pilbeam was very interested in it and I'm sure was twitching to get home to the drawing board...

I see no BMW badge. Is it badged as Sodemo engine?

This seems to be promotion engine. The Sodemo logo covers the spark plugs

[ss_collins]

Its a Sodemo lump - will not be branded BMW - unless it does well I suspect.

The cover on the plugs is normal tho - but indeed that engine is a very long way from ready - the finished version will debut at Brum

We spoke previously about GT1 engines. Another Pescarolo, the LMP2, could choose an engine which is not “race”. Can you say some to us more?

« The idea came from Jacques Nicolet, as the ACO suggested it in its rules: put a series engine in LMP2, to make more economic a class intended for privateers. Thus he charged us to a project of this type and it is in the process of seeing life. The car will turn at the beginning of October. In industrial term, one can call it a demonstrator. This production engine (which will be neither an engine from GT2, nor a diesel, Henri confirmed) will be installed in the #16, which we put in LMP2 2009 configuration. It will run at the same time as the #35, usually engaged by Saulnier Racing, in order to make comparative performances. »

Clearly this confirms that Pescarolo will use the Sodemo BMW V8.

Yes it would, extremely interesting

Wonderful, wonderful..

Please keep it up, love that nerdy stuff. And a BMW Sodemo in a Pescarolo chassis, ohh man...

Hey Hey HEY Would you guys stop it.

Your getting Aslak all excited here. . ..

According to the GT2 rulebook (which would govern the modifications for homologated engines) you can add sleeves if the block does not have them, or machine the existing sleeves for a larger bore... it doesn't specifically address re-sleeving. Interesting question...

4400cc maximum, twin-turbos allowed (2000cc petrol engines must use a single turbo in P2). Must use pistons, connecting rods, cylinder heads, and valves from a production engine (10000+ units). 3000mmb manifold pressure and 1 x 53.0mm/2 x 37.9mm restrictors. A comparable sized P1 engine would get 3500mmb manifold pressure and 1 x 55.9mm/2 x 39.9mm restrictors.

Ohhh yeaah

I presume this engine will be heavier than the Acura and Porsche ones?

What sort of power/torque do the Acura and Porsche engines have?

That's what the regs currently say but I think it is reasonable to expect some changes before 2011.

Then, there's something else that the Sodemo/BMW engine does...

If successful, it will announce to other manufacturers that, if you have a similar V8 engine in your passenger car production line, you too can enter it into Sports Prototype racing. All it takes is the proper engineering to make it work.

Mercedes, Jaguar,... Ferrari?...
