Those peugots are certainly not as bad as prost would make us belive ? Or the guys at Asiatech have done some goog job on a shitty engine. The engine was criticised for the small powerband but do u know that the cosworth of 2000 ran only till 17k max rpm? the Peugots got up till 16.4 k ..not much in it ?
Although Mika perhaps ran high wing in sepang..the asiatech outdragged the illmor...creditable to say the least..
So any guesses ..which company is funding the project...rumours on asian auto sites say it is Hyundai..while others say it is Yamaha..although they are laughable..the mysterious firm has done well thus far at least. Kudos Asiatech !

There were rumours floating around here a few months ago as to whom is supporting the ASIATECH cause. The rumours suggest that V.A.G is supporting the cause, and if that is the case, I am one happy guy. I would love to see an Arrows Volkswagen, or an Arrows Audi!

Yamaha? Laughable?

Don't talk nonsense boy.

The old Yamaha F1 engine wasn't the best, but considering the budget it was a little firecracker.

Don't forget Yamaha have a 600cc (roadgoing) motorbike engine that revs to 16500rpm and makes 120bhp. All with perfect reliability and good mid-range drive.

How do I know...... ? Because I've just been out on mine for the first time this year :) ahh 155mph is my benchmark speed for this year so far (did an indicated 167 mph last year, but the Law was out today)

I am afraid that Yamaha's F1 efforts have been pretty poor. They were appallingly unreliable - I remember seeing a team (I think it was Zakspeed?) wheel out their car at a Silverstone test session with a new ly fitted Yamaha, start it up, rev it once and it grenaded. And that was a good one...

Yes, Yamaha make good bike engines, but they were out of their depth in F1.

All i know is that AMT asiatech engine company is owed by the son of SONY electrical and entertainment.

The Yamaha F1 engines were badge-engineered Judds, and showed very well at power tracks Hock and Spa in '98, as well as almost winning in Hungary in the hands of DH. The OX11A was also the first F1 engine esigned to take full advantage of small diameter clutches, and used innovative screw-in liners to achieve a very compact and extremely lightweight design, likely the first F1 engine to get below 100kg without ECU and loom this using only very conventional materials.

I've heard that a few Ilmors (whoops I mean Mercedes) have grenaded fresh from the garage in testing this year, perhaps they are out of their depth in F1 as well?

Could it be that in response to Alain P's Whinning about the Puegoet's that Peugoet tuned the engine down to enhance reliability, decrease the number of motors and tech involvement and basically make the best out of a bad situation? I know that is what I would do..That would explain the found power.

Just a thought

PS: While we are on the topic of Motors, I know the Cosworth of last year had some probs, but wasn't it the lightest one out there? It certainly seemed pretty powerfull, propelling the ill handling Jag to a number of top ten qualifyings..The seem to be pretty quiet this year though, I wonder how this years motor is?

The first Yamaha used by Zakspeed in 1989 was the OX88 V8. It was a 75-degree V8. As mentioned it had some tendencies for going into orbit. This engine used the technology that Yamaha had used building their 2-litre OX66 V6 used in the Japanese F2 series and also the 3-litre OX77 V8 which were in effect an DFV using Yamaha´s own cylinder-heads pioneering the 5-valve technology. 3 valves were used for induction and 2 for the exhaust.

Yamaha took a sabbatical and were back in 1991 with the OX99 70degree V12. This was used by Brabham and was a little more successful than their V10. The V12 was installed in Eddie Jordan´s cars for 1992.

In 1993 Suzuki joined forces with John Judd using the GV engine block and with Yamaha 5-valve heads producing the 72degree OX10 V10.

This was developed into the OX11 and the final "C" version was used in their final year 1997 by Arrows and we all remember how close to a GP win they came in Hungary that year.

moog,
Your bike really revs to 16,500!? Is that a race version or just the regular R1? Wow! I guess the valves are still thrashed about by springs and camshafts?
What is the recommended rebuild schedule?

[desmo]

Rainier, the OX10 and 11s were NOT 5 valve/cylinder designs as your post implies. I talked to Stan Hall the Head Engineer at Judd's shop on this very point and posted a copy of his e-mail to that effect on this forum.

Do you normally travel at 155mph when the men with big hats and no sense of humour are around?;)

Rebuilds? Race engines?

Nope, it's the road engine, no re-builds necessary - it's standard, even down to the exhaust.

It's an R6, not an R1, and MacFan - no not normally ;)

[Rainer Nyberg]

Desmo,
Sorry about the misinformation regarding the Judd OX10 design.
Seems like an original source for the information was erroneus.
It clearly stated that it was a 5VPC engine as the V12.

But then all Yamaha badged Judds were infact 4VPC ?

I can't reveal my sources, but it is the most powerful on the grid, as tested last week. This is from the engineers themselves. They despair at the chassis, and most of them rate Irvine as pretty good.

Jaguar will be the class of the field eventually - you only have to talk to the guys doing the work - and then remember that they are being bankrolled by Ford.......

...they have the money, and the ambition.

"I can't reveal my sources, but it is the most powerful on the grid, as tested last week. This is from the engineers themselves."

How would the Cosworth engineers know precisely how much power the other team's engines make in order to make such an assertion? I cannot see anyone having access to enough data to definitively state which engine is the "most powerful". Educated guesses sure, but that's all.

Will they try to buy Ferrari this time too?
