see... you clearly arent understanding what i was try to show.

Of course a car doing 130 compared to 110 is FASTER...

or did you mean quicker?

nope, as I know that a 200bhp Fiesta can be driven round a circuit quicker than a Ferrari driven by a donkey.

I used these laps/plots as the corner speeds are near equal for the lap - the only differences are really on the straights.

I didnt conduct this as a test..... as the laps were done 1 year apart

I thought it was pretty obvious really, even without looking at logs when I had my little Fiesta I was able to keep with Focus RS's around twisty sections of track, soon as a straight comes into it they fucked off. Just a simpler version of what you are saying isn't it?

I don't understand the point he is trying to make though More power means she's faster down the straights, they go around the corner at the same speeds, that's fairly obvious, I can't see any other point being made here?

fees = 420bhp/tonne
yours = 250bhp/tonne

even without looking at any data you would of been able to tell which is going to be faster at the end of a straight.

Could be any figure for how much time, which is where all the other variables come into it.

You are treating this as the cars are exactly the same, with the exception of the straights, hence the one with more power goes quicker and 'quicker' will increase with power.

Although to a lesser amount than the extra power, the fact it's 2 different drivers in completely different cars will also be causing some of that.

right i get you now.. you want to know how much time you gain by having x amount more power.

wouldnt you be better looking at similar cars on a drag strip and comparing times etc?

So basically because Knockhill has 4 main straights, through the power difference she is getting a second up on you on each straight, despite you being able to brake later due to a slower terminal speed. Thus being 4 seconds a head per lap, which is quite alot for such a small circuit.

So basically, you need more power/balls/tyres?

Also, you could have the same power as Fee but you'll lose more through the drivetrain won't you? I seem to remember you mentioning the GTR is mostly RWD until it goes wrong whereas yours is constantly 4WD, yes?

Hard to see the track in Fee's due to being a small video, but she seems alot smoother aswell, your car is bouncing everywhere and sliding hers just looks calm

Better driver IMO

no i dont want to know anything - i didnt ask a question.

I have data for these 2 cars under those conditions

I'm simply showing that a 600bhp GTR is 4.5secs a lap quicker than a 300bhp Impreza when the corners are taken at nearly the same speed.

You could use the same model with Umar and Jimmy if they did the same corner speeds - but they didnt as the slower (less powerfull car) was quicker over a lap.

That's a good thing, they're nothing but a pain in the arse to own. Sensor faults everywhere

R32 GTR in grey and totally standard would suit me

i dont think my driving lacks 'balls' - perhaps it lacks calmness.

KH has 2 main straights and 1 medium

its a statement.

"how much is gained from more power?" would be a question

I'm not being pedantic with that by the way.

Chris - to answer the obvious bit

So you knew that a 600bhp GTR was 4.5secs quicker over a lap oh KH even when the corner speeds were roughly the same?

Thats amazing
