Rolling road results

[pete]

I've just got my Griff back from a major service at Austec, with the obligatory rolling road results.

Final figures were 273bhp at 5300rpm, 300lb.ft of torque at 4300rpm. It seems to have revved cleanly to over 6k (to 6346rpm to be precise ), and is still churning out almost 260bhp at 6000rpm. Torque's well down by then though - it's only 225lb.ft at 6k, but a more useful 282lb.ft at 5k.

Paul seemed quite happy with it, and said it looked like it could reach a genuine 300bhp with remapping, a ported plenum, and a larger throttle body...

Anyway, here are the graphs for anyone who's interested.

Power:

Torque:


The car's a '97 with a bog standard engine, and has covered just over 42,000 miles.

Cheers,
Pete

Is it a 500? whats the average power figures for a 500??

Anywhere from 240 to 290bhp at the flywheel for a standard 500.

290 for a standard 500 is pretty rare I think. More like 240-270 for a sorted standard 500.

good readings for a standard 500 with those miles. Similar to my original figures.

Plenum / chip etc will up peak a touch 300bhp, 404 cam will giv another 10bhp but lose some at 2-3000revs, but you have plenty there! Will keep your torque curve (and power) going all the way. THAT'S THE IMPORTANT BIT

Nice!
