Pinto Power
has anyone had there car on the rollers ?
I'm just looking for a rough idea of the power and torque figures you've achieved - ideally from something similar to my spec (i.e. 93mm
pistons, std 2.0 injection head, 285 cam, ZX9R carbs)
thanks - robert

should be looking at about 130-140bhp depending more on the rolling road you goto than anything else

I would think that's about right.

Std injection pinto was quoted by ford at about 110bhp. So with those mods you will be looking at about 130. But as has been said, it depends how well
'calibrated' the rolling road is.
Hoping to take mine to be set up next week as its now got the proper head on and the FR33 in. Running a touch on the rich side.

Will you be popping down to the next kit car meet?

I have a very good (modified) RS2000 pinto available with all the right bits. PM me.

Thanks everyone,
I'm sort of aiming for about 130+, so I'll wait and see - next year probably  but at least I've got nearly all the bits now

any guesses for engine speeds at peak power/ torque ?? I'm going to have to make some gearbox and diff decisions soon

These figures that get quoted for rolling roads (see above e.g. 130) - that is real world BHP measured AT THE REAR WHEEL right?
If so, how much do cars loose via tranmition? On a bike (my background) you expect to loose anything up to 10% via the final drive (chain etc), how
does that compare with this type of car and so are the above figures actually guesstimates at crank HP?

the 130-140 i was talking about was a flywheel value - or estimated flywheel value
not sure how much of that you loose sorry.

I thought it was ~15% for most rwd cars and ~40% for 4x4

Power losses depend on the mass of the rotating parts. On high power, high weight cars around here it can be a fair bit. 20% or so with a manual
trans. A smaller, lighter locost should be a lot less.
Also you should always use corrected numbers as well. These compensate for altitude and temperature so that in theory you can compare to any other
corrected numbers on any other dyno. In reality you should only compare to other dynos of the same make as they all read different.
BTW: BHP is engine power with the best intake/exhaust and no accesories.
SAE HP is engine power with OEM intake/exhaust and accesories
WHP is with everything, measured at the wheels.
All 3 will give you different numbers.
I think the pintos here were only 80 sae hp....
