McLaren F1 with the power of a Veyron

[Gutless vvti]

How fast do you reckon one of Gordon Murray's finest would go with the power of a Veyron or Veyron Supersport? (and appropriate gearing).

Might seem like a pointless/daft question, but it really is amazing how McLaren achieved 240+ mph 20 years ago with a naturally aspirated engine not much more powerful than a (for example) Carrera GT..

Would the mac not need to be bigger to hold that engine thus making the point irrelevant?

Hopefully McLaren will give that a good try at blowing the Veyron SS out of the water with the F1 'sucessor' due out in the next few years.

I really hope they do.
Gives me a warm fuzzy feeling inside just thinking about it.
I had a poster of the F1 on my wall when I was younger and still prefer it to the Veyron.
Go on Mclaren.. stick it too 'em

I didn't say with the Veyron's engine, I said with the power of the Veyron, or Veyron Supersport

[swifthobo]

there's more to it than outright power apparently the air resistance at 200+ is incredible, plus another vote for mclaren over bugatti

From 627bhp and 241mph as starting points:

987 bhp = 280.349 mph

1,184 bhp = 297.882 mph.

Yeah, but the Mac does pretty well up to ~240 with 'only' 627bhp, while the Bug uses '1001' to get to... 256 or so. That's a whole extra.... 374 (if the '1001' gimmick is to be believed) bhp to get 16mph.

That's more than half of the Mac's power. So while air resistance is a massive factor at speed (weight means nothing other than for acceleration and braking, not for maintaining speed), I can see the Mac taking all that extra power (374 ish more) and having a higher top speed (geared appropriately) than the Bug SS.

Of course, this is an entirely academic exercise, so why not stick an SRB from the Space Shuttle on the Mac if we want to see how fast it can go?

Zwolf, are you taking into account the fact that air resistance quadruples every time you double speed, and suchlike, or are you just scaling it up linearly?

To add something that may be of interest.

All this talk of aerodynamics, airflow etc. When I first saw the Mclaren MP12-4c in test mule mode early last year, I thought it looked very much like a progression of the SSC Ultimate Aero



(Which itself is a blatant rip off of the Lamborghini Diablo!)


Bare with me!

High flanks, Low nose slitty head lights etc.
Are we at the point, with the ultra high speed stuff that form follows function, to the point they all look the same apart from some 'signature' intakes etc?.
Not to take away from the Mclaren, It's a stunning looking car. but could be anything really,

It almost looks like the Japanese 'computer trying to have soul' kind of design (Lexus LFA?)


Well, that's what's in my head.

I'm going to get back in my box now. thanks

when top gear did that drag race the F1 rinsed it off the line yet the book says it is quicker to 60. was it just a bad start for the veyron?

From the info here, which takes account of the non-linear nature of increasing air resistance with speed: http://www.pumaracing.co.uk/TOPSPEED.htm

I've taken speed to increase as the cube root of the power increase.

987 / 627 = 1.57416

cube root of that = 1.16328

1.16328 x 241 = 280.349 mph (and likewise for the other example with the SS power output in bhp)

Vehicle weight does have an effect upon top speed, through the effect of rolling resistance. It is a relatively small effect, but it's not nil.

That race was filmed in Dubai, so I can't imagine the heat would have helped the Veyron, with it's forced induction, or was it Abu dhabi?

was it not a GTR spec car as well? and pro racing driver v telly presenter

TBH I don't care which is fastest, its all willy waving tbh, where are you ever going to use that much power, in the UK your going to do prison for a long time if you even look at the gas pedal for more than a couple of seconds

Both cars in performance terms are "adequate"

Pick the F1 if you have racing drivier reactions, Pick the Veyron if your a ham fisted knuckle dragger like me and don't want to die
