The Renault V8 Engine

[Juzh]

BTW Piola said that the Ferrari, the Renault and the BMW V8 where the most powerful in 2006, before the freeze. Top speeds tend to confirm that.

Bmw and merc had nothing on ferrari:
Interesting part starts at 9:30


On the power much sooner and harder than schumacher, only to be left for dead on full throttle.

This looks as much a setup difference than just pure engine power. I wouldn't use a wet Hungarian GP to demonstrate the difference since Mclaren may have been running a much higher downforce setup.

Renault was definitely powerfull back in 2006.

With the first freeze (2007) they seemingly lost a lot of ground to Ferrari and Merc, Renault accused them of having a very "liberal" interpretation of the freeze.

All engines were tuned in 2009, the rules forced another 1000 revs to be dropped from 19k to 18k and 8 engines per season instead of 1 engine = 2 full weekends, but Renault had an authorization to change more.

Found a slightly better video, Monza, BMW vs Renault.

Yep. That is a pretty good example. Alonso had the better exit, made up ground then lost out down the road to the BMW.

And Viry says they tested a desmodromic valve system and two different cameless valve systems on the RS26 (pneumatic and electro-pneumatic) which brought many interesting advantages... Are cameless systems allowed on todays V6t?

Not sure, but variable valve timing systems are forbidden, which would negate the advantages of the systems you describe.

. . and since cam less systems usually open and close valves at a fixed rate WRT time, the rate WRT crankshaft rotation will vary with revs. Arguably this would represent VVT.

I specifically registered to reply to this "logic".

Take some time and try to understand the following: http://en.wikipedia.org/wiki/Differential_equation (as a bonus you'll also understand why KERS or any time limited power boost is used at lower speeds rather than at high speeds)

And while we're on wikipedia:

As an engine supplier, Renault has contributed to nine World Drivers' Championships[3] (1992, 1993, 1995, 1996, 1997, 2010, 2011, 2012, and 2013 won by Nigel Mansell, Alain Prost, Michael Schumacher, Damon Hill, Jacques Villeneuve and Sebastian Vettel (last four) respectively) and ten World Constructors' Championships[3] (1992–1997 and 2010–2013) as engine supplier for Benetton Formula, Williams F1 and Red Bull Racing.

And add the 2 championships won in 2005 and 2006. But hey, winning 12 constructors titles in the past 23 F1 seasons could also simply be luck. A video from one race in 2006 probably is the better indicator of the quality of F1 engines.

Good day.

Coffee- While I understand what you are saying about the most effective use of a limited amount of supplemental power from KERS, in reality things are not quite so simple. With F1 cars at low speeds you must also consider that there is a limit to the amount of power that can be applied to the rear tires before they lose traction. And as the car speed increases the amount of aero downforce produced on the rear tires also increases

Did Renault/RBR ever use 'hot blowing' in the exhasut blown diffusers era or they sticked to their 'cold blowing techniques?

[Tommy Cookers]

didn't this era/type of blowing start with hot blowing, and was later limited to cold blowing ?
(even then hot blowing was still allowed over 15000 rpm)

Indeed, the current cars (in spa spec at least) seem to be traction limited until around 170 km/h looking at the onboards.

I dont know. AFAIK RBR started that era with cold blowing early in 2010 then Ferrari and Merc used hot blowing for their new EBD then https://scarbsf1.wordpress.com/2011/07/ ... -analysis/

Looks like cold blowing first, then hot blowing, then FIA smackdown (though iirc they did allow Renault (and others?) to finish out the '11 season with cold blowing. Because 'our car was designed with ex blowing in mind, wah wah, etc')
