Dome LMP Discussion - Page 45

gwyllion · 11 Jun 2012, 15:27 (Ref:3089062)

In 2010 RML raced with a Lola LMP2 coupe with the HPD 3.4 V8. So it might be possible got up the HPD engine after all.

There is also the Zytek 3.4 V8 which in the past was installed in other chassis (e.g. Binnie Lola, Embassy WF01, WR LMP2008) and the Mazda AER 2.0 turbo.

However the main problem is that a high revving V8 is not ideally used for endurance racing. This comment from Henri Pescarolo says it all:

Quote:

Early problems for the Pescarolo 03 are a worry: "Before we had the Judd V10 that was ideal for endurance races", he said. "With the new block, it's different. In 30 years, the laws of physics have not changed ... The Judd V8 behaves in a Pescarolo as Cosworth V8 in a Rondeau: it vibrates."

i didn't know that toyota was using a katech LS7R...
Reallisticly i believe that toyota's engine torque peak will be around 500-525Nm but with a much more efficent destribution.

chernaudi · 11 Jun 2012, 20:59 (Ref:3089245)

That's combined torque from the gas engine and the electric motors when activated. The Audi R18 e-tron has about 900 nm from the diesel engine alone, plus whatever the electric motors give.

In http://auto-racing.speedtv.com/artic...nic-minassian/ Minassian explains a bit the collaboration between Dome and Pescarolo regarding the development of the S102.5.

Quote:

It's a factory effort. All of the engineers from the [Dome] factory are here. We've been going through the wind tunnel and development is regular. There hasn't been a test session without a new development.

On the other side, the Pescarolo team are working on mechanical developments on the car. The suspension has been made by Pescarolo. It's a joint effort. One is working aerodynamically, the other is working mechanically.

Sounds interresting!
A Great and cheap pickup for any manufacture!
Could give some interresting PR options for Renualt/Nissan

^yeah right.

nissan should go the toyota way and build their own car. full factory support and all. no more of that badge-engineering crap plz. factory chassis, factory engine.

the last cars built by nissan that ran at le mans were the skyline r33 gt1 of mid '90 and the 300zx imsa gts. The group C cars were lola cars, the R390 was a TWR car and the R391 a modified courage. In my opinion nissan hardly will enter in 2014; for now the manufacter has even too much visibility as the best lmp2 engine supplier (and badging the deltawing).
Surely the easiest way to enter is to supply the VRH34 to the dome coupè, badging the whole team but without support the team.

lms · 12 Jun 2012, 13:06 (Ref:3089537)

or maybe whoever develops the gt500 aero for the gt-r could construct an lmp1 chassis?

alexkiller8 · 12 Jun 2012, 13:18 (Ref:3089544)

the whole gt500 program is under the nismo control

R391 was designed and built by G-Force. Bespoke car all the way. Car was designed by Nigel Stroud.

The whole notion that a 'manufacturer chassis' does not include a tub fabricated by contract somewhere else seems bizarre. Most manufacturers don't have the facilities. TMG is in some ways an external contractor now, their ability to sell wind tunnel time to F1 teams that are doing an end-run on the RRA has helped keep them afloat. If Nissan engages someone to put together a tub for them it's still a full factory chassis IMO. If. Not holding my breath! Ditto not holding my breath waiting on a Nissan in the back of the Dome.

Absolutely correct.

Mike_Wooshy · 13 Jun 2012, 18:17 (Ref:3090300)

Also wasn't the earlier Group C cars from Nissan built by March ?

Yes they were, up to and including 1988.

According to Racecar Engineering, Rebellion Racing is realistically looking at running the DOME S102.5 by the end of the season since they might not have enough parts to support the Lola B12/60 Toyota through the end of the WEC season due to Lola's administration

gwyllion · 17 Jun 2012, 22:53 (Ref:3093848)

http://audio.rpix.org.uk/lm24/2012/2012_lm24_pll.mp3 has a much longer interview with Bart Hayden. He contacted Dome during the winter, when he found out that Dome was going to update the S102 to the current rules. However, no deal was made because Rebellion wanted two cars.

Also, this might be the only way to get the Toyota engine they asked for

MitchZ06 · 18 Jun 2012, 02:07 (Ref:3093899)

Would be a feel good story that's for sure if Dome can supply 2 chassis to Rebellion.

Japanese Samurai · 28 Jun 2012, 09:27 (Ref:3099316)

According to Sports-carracing.net,
Team Rebellion are wanting to use S102.5.
And Dome and Pescarolo are discussing the collaboration after Le Mans.
It seems that foundation of the joint venture is also included.

Simmi · 28 Jun 2012, 09:32 (Ref:3099321)

Would LOVE to see a two-car tie-up between Dome and Rebellion next year. I think that's a partnership that, as a manufacturer, I could get on board with.

A few more WEC rounds with the PescaDome this year would be nice too. Henri needs a few more chances to clock some form of good result if he wants something to happen next year. I don't think the 03 will enable him to do that.

The Badger · 28 Jun 2012, 10:30 (Ref:3099343)

Henri would be better off racing an Oak/Pesca P1 , with a HPD or Toyota in the back of it .

alexkiller8 · 28 Jun 2012, 10:35 (Ref:3099348)

in my opinion rebellion more than try to obtain a pair of dome should try to obtain from honda 2 arx-03a cars! be realistic, for now the #12 is a bit more competitive than the strakka #21 because lola did a good work on 2012 bodywork but... can we say the same about dome? then, as shown at le mans HPD is giving to their teams bodywork updates to be ever more competitive, so i ask my self: once rebellion will put their hands on a pair of dome 102.5, will they be competitive like now? i think no.

Deleted · 28 Jun 2012, 10:44 (Ref:3099352)

So by the end of the season we might have Lotus branded Domes... powered by Toyota

I hope Hayden decides better of it

Speed-King · 28 Jun 2012, 10:48 (Ref:3099356)

Well, Lotuses have long been Toyota powered so there actually would be a bit of continuity to that.

Also, Dome was involved in Toyotas Group C projects.

That is not an option if Rebellion wants to continue their partnership with Toyota.
