I've voted 90, it'd make it quick without being too mad. What's important though is flexibility - 90bhp at 7500 revs would be great but quite probably have bog all bottom end torque. Bags of mid range make the car an easy drive, it can get wearing if you have to be thrashing the nackers off it every time you need to make a little progress.
An example being an old **itroen BX 16v I used to have. 7.4 secs to 60, 136mph top end and 160 BHP it had. Figures there look great, yeah?
Downside being the torque curve. Was ok up to 5000 revs, then the curve became TableTop Mountain. At this point, it took off like it'd just had it's arse branded, right the way to the machine guns at 7000 revs.
"Great!" you say.
Yeah, at times would be my reply. To make any progress - i.e. to pull out quickly into a faster stream of traffic, or get into a small gap on a roundabout, you had to knock on the door of Mr Rev Limiter. Fun, but becomes wearing after a while. Bags more mid range would have made progress less frantic, plus when your mum - in - law and family is in the car if you're thrashing the nuts off it it doesn't always impress.
Mind you, when MIL asked:
"Why did you trade in the Cavalier for
this?"
my reply was:
"Because it wouldn't do
this" - then dropped 3 gears, nailed it to the limiter in 2nd, 3rd, and 4th.
I could tell she was really impressed
So much so that she didn't ask again
