Cant wait to hear what you get from it !

Check oil water fan belts etc etc etc

Make sure you stand in the rolling road area as the noise of a car on rollers is scary - especially if its your own car ! - lol

1st Run 131.9bhp / 132.2 lbft @ 5908

2nd Run 135.7bhp / 136.6 lbft @ 5551

It is known that these rollers read low. Had to have the IDF's rejetted as the carbs were jetted with the Aux jets upside down.

Compression as spot on & all equal with in 1%

what the rule of thumb % loss from a RWD, is it 15%

No idea...

Be nice to know roughly tho

mine made 320 @ the wheels, last time
Kel

I thought is was 15-20% for RWD & 30-35 for 4wd

1st Run 131.9bhp / 132.2 lbft @ 5908

2nd Run 135.7bhp / 136.6 lbft @ 5551

It still has its loverly flat torque curve

And the IDF "dip" at around 2000 - 2500 as well

Did your man try near the 7000rpm area ?

I have had the engine held at 7500rpm (as you well know - lol)

If those figures are at 5500 - 6000 rpm then engine is still near or on the 175bhp @ fly that I had from it

NICE ! :cheers:

p.s. Aux jets were direct from Australia :geek:

HP figure are very misleading without knowing a bit about car and rollers.

Anyhow a RWD escort will lose between 32 and 38 hp to the driveline.

I am very happy for your figures.

But

the rpm is very low for that figure.

I would have expected closer to 7500.

Can I have engine specs?

So do all escorts loose that amount of power to wheels ?

Say 40bhp tops ?

And its not a percentage...the wheels to flywheel figure is doing my head in...

Best just keeping with @ the wheels figures...
