How much hp for 3mph more terminals?

[edde]

I'm interested if anyone knows how much extra power you'd need to get a few more mph?
I went round Bedford race track a few week ago and the oil was cooked but at the end of the stright I was doing 95mph last weekend though i was doing 98mph now my speeds out of the bends were no quicker (probably slower as my tyres were worn) and I wan't taking any different lines the only chnage was the fresh oil.
So how much extra power had the new oil unleshed is there any formula or concept?

your just bitter that you lost lmao.

when i had my first oil change at 18k, the engine felt much more responsive - and now i change it every 9k. personally dont think it gave me anything in power, but certainly some response.

Ha ha I'll get you somehow I'll bring my Clio next time and beat you.

I'd done about 6 track days on the oil that was in and worn though more than one set of new tyres so the oil was truly cooked.

The oil that was in had only been in for a week and done Bedford the day before so that was the good oil I'd hate to think how much less hp I'd have had with the old oil.

20-25bhp? at a guess,

Wouldn't have thought that much the car only got 65hp.
I thought maybe at best 10hp but that seems a bit much.

well.... Power = [(mass * acceleration) - Restive forces] * velocity

....if that helps

difference in air temperature might have helped too if there was any?

 

[dick]

nt just wind temp... wind speed/ direction

Thats actually the formula for thrust, power is (rpm x torque) divided by 5252.

I believe what I was trying to say before the "Cat jumped in" was t..yres make the difference.............!!!! Don't ya know.
