My Dyno Run

[Timbo]

FWD cars - add 10 bhp to the wheel figure and divide the result by 0.9
RWD cars - add 10 bhp to the wheel figure and divide the result by 0.88
4WD cars - add 10bhp to the wheel figure and divide the result by 0.84

Do you have a source for that? I mean, there are any number of formulas like that which get to the same result, but what is their basis?

By the way guys on Wednesday or Thursday I will scan my graphs and post them up for everyone.

Cool! Thanks. I also found one by a dyno operator suggesting wheel slippage on the dyno rollers is also a factor, although the maths wasn't very convincing

They're just dyno results, don't base your car's overall worth on them. A better question may be - do you need more power? If you do, what sort of power do you want? If you want to obtain it crudely, cheaply and easily, then there's many, many dp advocates on here. But if you want power that can be sustained, then consider options that lower intake temps. See Guy's earlier comments re what happens and think about why your peak power dropped off and couldn't be sustained.

Yeah I can see were your coming from but I was just expecting a little more. In regards to the graphs I want to post them up for people to look at and tell me if its normal that the power and torque curve is all over the place like the share market and not a nice consistent curve.
