Rolling road results

[WaxDaddy]

So has anybody else put their bog standard 5.0 on a rolling road?

Did mine today

first run was 421 bhp (426ps) and fairly consistent around that number till it got a bit warm and then dropped to 415 bhp (421ps)

Not bad at all!

That's excellent! ..... was that on unleaded or super-unleaded? .....

And ford register it as what? 430 odd is it? to get even close to that is something special, now imagine what a tune will do and a few upgrades.

430ps in the US but not here, our RHD manifolds drop the power to 421ps (415bhp-ish)

This was on vpower

Would be more with sequential tail lights )

And some 'Go-faster' stripes? :lol:

Did you mean WHP?

The dyno sheet doesn't say but I remember seeing it on screen and it was 350-ish but I can't give an exact number sorry

15% powertrain loss sounds about right.

 

[RoyalGuard]

15% is a standard used by most softwares, is yours an auto or manual, if it's an auto that's even better, some new cars we can see about a 6% PT loss all depends, good numbers though

Why/how is it measuring bhp and not whp?

 

[RoyalGuard]

It calculates the loss from engine to wheels, it's reasonably accurate within 1-3%, I'm more for what it puts down at the wheels, problem with it is some cars can loose 30% power and others only 5%, it usually flatters autos and 4wd and makes RWD or FWD look bad, only time I have ever used the calculations is when I'm pushing a car to the maximum and don't want to go over a certain power with the internals,

 

[stoli]

I've just never heard of a dyno ("rolling road") resulting in estimates and not a real whp number. An estimate is worthless as a tuning tool and to say I have 500bhp doesn't mean jack if I can't get that power to the wheels....

Edit: And how is it a 'problem' when it reports the real values instead of fairy dust estimates?

Is this a common UK thing?
