my top speed - 60mph!?

[mk1rob]

well not exactly, but can only cruise at 60mph comfortably doing nearly 5000rpm. Ive got a 2l pinto (standard), type 9 5 speed, 4.1 diff and 175/50/13 wheels/tyres. Is this normal for that set up or do i have some strange gears in the gear box? It accelerates well but just dont have top end speed. Could probably get 80mph only if i really cained it

That'l be down to the 4:1 diff and the low profiles then

As above, you need to change your final drive ratio and/or your tyre size.

 

If you like the low tyres go for a tall final drive such as a 3.5

[Stiggy]

A 3.54 will knock the edge off of the acceleration.

 

Maybe a 3.77, but a pain if you have to get diff flanges swapped, most 3.77 had the smaller flange.

 

But then again if it's a MK1 escort diff it should have the smaller flange.

 

Is this a standard engine ??

 

I had a 4.11 in my last Escort, 4 speed Quaife and it was OK, but did have 7000 rpm available and 205/60/13's.

Ah ok thanks for the help. Ive just got this diff and its LSD so dont really want to swap it. Looks like ill just have to put up with it for now. Just a pain if travelling in convoy with someone as i get left behind.

 

Thanks again
