What revs ?????
 
This might be a stupid question but here it goes ... at 80mph what revs is your car doing in 5th gear.Mine is doing 4 1/2 thousand and it seems as if i need to change in to another gear ... is this about right ???????? cheers waz

Not so stupid me thinks, I was going to post it a few weeks ago but forgot :cuckoo:
In answer to your question then, mine is bang on 4k @ 80mph :thumb:
Dno about right or wrong, there must be quite a few factors involved like wheel size and gearbox ratios for starters:wonder:

I agree with b13bat - 4k @ 80mph in 5th.

Strange, as all MY93-96 WRX's have a 0.825:1 fifth gear and 4.111:1 final drive - so yours should be at c.4k too :confused:.... You haven't got really small 15 or 16" wheels on with really low profile tyres, or something? (Even if yours had a Type RA transmission in it, you'd be pulling 5k @ 80mph in 5th, so it can't even be that! :wonder:).

Cheers slip.

There you go OP... As eluded to, you should be pulling near 4k in 5th (3888rpm to be pricise).

So, something's up, and it's not your wheel/tyre combo, as you have Bugeye WRX 17" alloys - so if anything, your rolling circumference is actually likely to be greater than (or at least equal to) OEM anyway! :wonder:

Even if it the rolling circumference was lesser by a few mm (or possibly cm), it wouldn't account for an increase of some 600rpm IMO anyway.

Waz, surely at 80mph you should still be in 3rd :lol1:
