Just browsing some vids and noticed this in a couple of vids...

4th gear

my old williams does a ball hair over 110 at 7k with willy box

my hybrid does a ball hair under 120 at 7k with 19 box

Though the ratios were the same?

same manifolds, same tyres & wheels sizes...

I think they put different ratios in depending on what year they're from tbh. The gearbox I bought my car with had better ratios then the one I put in when I blew it up and they were both the same code and from the same year car.

See ya

Cams can't make a difference to the top speed in a gear though. That's dictated by the revs and the gear ratios. :?

Yeh cars can't go any faster that the gearing allows. Only way you can get extra speed is by changing the gearing (or putting taller tyres on) or getting more revs.

There was a guy in Wakefield yesterday claimed his Scooby WRX did 177mph on a standard WRX box. Errrrm no, my mates old one flatted at 130mph just got there fookin quick.

See ya
