Right. That's one hell of a lot of frig-factor included, then.

I think he's implying that 20bhp is a lot of transmission loss.

A swift bout of bistromathics says that's about 15%. Given that none of
the numbers anyone's banding about are very precise, it doesn't sound
too unreasonable to me.

I'm sure I've seen people quoting much more optomistic figures after a
visit to a rolling road on here.

Indeed which is why, in the absence of taking the engine out and running
it on a dyno, I figured it wasn't too far from reality.

Quite possibly but not for a 25 year old well worn gearbox driving a 25
year old well worn live axle.

Can someone explain why anyone would spend time and money trying to hot
rod some antiquated POS when after all that effort they *still* end up
with an engine that can barely match a diesel mondeo?

Why not start out with a car with a decent engine instead of trying to
polish a turd?
