Scott lap time predictions

Peter
Th F50 has less power than my car, but around 200kg less weight. In fact a better comparison would be the 430, where with a passenger, performance would be close to being identical, unless he plans on modifying the car.

With NEW P-Zeroes, as his car probably has the originals still fitted;

At PI, I'd say he will struggle to beat 1:52-53. With sticky rubber 1:45-1:47. Winton 1:36-1:38
Calder - No idea
Sandown - 1:21-1:23

 

I honestly can't guess this one

The F50 now has new tyres stephen. It also has a lot less weight than your 550, lower centre of gravity, decent downforce, very low unsprung weight etc....

Surely it HAS to be faster than any normal 550 by a fair way... but how much... and stephens 550 is now AMAZING.... It's the fastest thing point to point on the road you could wish for. Around town etc it blows away any other Ferrari I've ever driven... inc F40. Easily. with knobs on.

On the track, the F50 is going to be very fast... but the $$$ risk is always going to hold you back.

Can't pick it.

 

No doubt with the same tyres it would be much faster than my car, but on street tyres I don't think so. As I've said it should be a bit quicker than the Andrews 430 if he runs the street tyres ie low 1:50's, on Hoosiers mid 1:40's.
Of course with someone like Allan at the wheel, another 2-4 secs better again. I look forward to eating my words,as long as I'm invited to the event.

 

After checking Procar GTP times I have some new numbers to think about.

WRX Sti
Phillip Island 1:45, Sandown 1:24, Winton 1:33

Scott should be able to equal these times at Phillip Island, Winton and decimate the Sandown result.
Remember the Sti's are limited to 1300kg min weight and 1.1 bar boost in GTP.

Just makes me realise what a **** driver I am

 

fastest or quickest, there is a difference, lancer evo 9 is quick to 100kph but not necessarily fastest to a top end, and what makes Stephens so special to the "base" models. but then given a flat and straight enough piece of road we can get a datsun 120y to be fast (given that the diff ratio is altered to 9.66 to 1)


stephen,
u heard ftom the emmissaries from up north?

 

No...
Got my car back Sat night from Phil, really wish I could have been there.

 

goober.

I think stephens car is both fastest and quickest on the road. The 4 wheel drive of a subie/mitsi will always get you the first 30m faster, after that, it's see ya later.... with the bird out the back window.

I'm gobsmacked how well it goes... considering the fairly small changes made. It get's going so soon, and stops and turns like a small car...on the road.

The GTP times are with slicks stephen, and lets just say that many rules get bent in GTP with regard to boost etc.......

Floyds commodore is a similar benchmark to 550. He's got about 500BHP, not that he'd admit it.....

 

I have been tracking a 360 Michelotto for the last 2yrs. An F50 is a great road car; but it isn't going to be anywhere near as good on the track as the Michy. Additionally the F50 is vastly more expensive and not as safe should the worst happen. So to be honest, if it goes on the track it will be just a gentle cruise around far below the limits. Besides, all the "competitive guys " are going to be banned 'cause they're "spoiling it for everyone else" ROFL

 

You say that now, but I'm sure you'll push a little harder once you're actually on the track.
As to ruining other peoples fun, the "competitive" runners are the only regular participants. Everyone else seems to be more interested in the "show and shine" scene. Many of the spectators are only there to see cars such as yours and Gils, so it would be a real shame to see actual participants having their fun ruined by the concourse set. The last event was fantastic, I only hope the rest can be so unpopular.

The difference in weight between the F50 and the F40 is greater than the difference between mine and Scotts, according to the spec sheets. F40 has almost as much HP as F50 with much more torque, hence my thoughts...
In fact more detailed analysis, not taking into account torque or area under the curve through the gears;
F40 kerb 1100kg power 480hp torque 575nm 2.35kg/hp, F50 1350kg 520hp 471nm 2.6kg/hp, F430 1450kg 483hp 465nm 3kg/hp, SS 550 1580kg 590hp 650nm 2.7kg/hp(revised power figures derived from data logger)

The F40 should be noticeably faster.

 

stephen... does your logger now claim 590BHP and 650Nm! WOW!

And did it also verify the dyno'd 541 BHP BEFORE the flywheel and cat pipes were changed??

 

Also, F40's have terrible drivability compared to F50 and even 550.

F40 Power delivery, although manageable, is no where near as efficient as the normally aspirated cars. And the F40 chassis twists and groans with the load.... still the most desirable car, but not a particularly good one when analysed closely.

PP, you're quick with these.... what's the Offical Fiorano times for each....

 

and stephen... you really must get some 355C front brakes fitted now (great brakes, and 25mm thick pads)......

 

Put an F40 on the chassis dyno with the front and rear bodywork removed and WATCH it twist on full power.

You cant hear the "groaning" when driving.

 

I honestly think that any road car, EVEN an F50 will be a disappointment on the track after the Michelotto. I remember a test day at PI when the Michelotto shat it's clutch after 5 laps. I had my M3 CSL with me so we went out for a few laps in that. The CSL is rated by most magazines as a great club day car; but I didn't enjoy it one bit after the brief outing in the race car earlier in the day. All road cars are out of their element on the race track, far too compromised- even the F40/50 and Enzo. So yes, I will inevitably take it out for a blast; but it will never be running against the clock for that last 1/10th of a second.

You are correct about the complaints. They come from people who rarely, if ever venture out onto the track. More than happy to look at the cars though........

 

If I had to nominate times for the F50, I think those you mentioned would be on the money.

 

Hi Scott,

I was wondering, can the same be said of the 360CH? I know it isn't as hard core as the Michelotto, but is it a 'racer' that is in its element on the track?

BTW, congratulations re the F50!

 

OT but yes 426hp at rear wheels (315kw) at Sandown. DynoDynamics figure was 322kw which software estimated as 541 flywheel hp. On standard car 292kw @rear wheelswas estimated at 486flywheel hp, so the calibration seems right. Latest number was 465rwhp. Hopefully confirm on dyno tomorrow.
Interesting what extra revs and ECU will give as peak power is produced at rev limiter. Just leaves machined throttlebodies, gas flowed intake and headers. Hoping for 650+hp, in conjunction with 100+kg further weight savings, resulting in near Enzo performance, without all the electronic BS.

 

I saw a CSL today. Rego 00 CSL. Sounds like a bee in a tin can... with hobnail boots on.

I can't believe BMW have made a car that sounds THAT BAD.

Anyway, 360C on track with slicks are a race car... but they actually come delivered with road tyres.

My numbers come from Ferrari's figures on the owners site. Where are yours from? Weights are kerb weight, all fluids, no fuel.
