What speed will a 2wd cossie do with a 7200rpm rev limit in each gear. Standard diff and box, with 205/40/17s and 215/40/17s.

Thanks

Steve.

 

1st = 47mph
2nd = 72mph
3rd = 104mph
4th = 139mph
5th = 174mph

 

What size tyre is that with Mike ????

Steve.

 

Surprisingly - what you asked for .

 

But i asked for 205/40/17s and 215/40/17s

So which one did you do ?????

Steve.

 

I thought you meant you had one size on the front and one on the rear . It is for the 215s. Obviously the 205s will be a few mph slower in each gear.

 

Don't suppose anyone has the 909 sport box ratios???

 

.........why mike........are the side walls a bit taller on the 215's...?????..............and while ur on nice chap.............whats the speeds on std 4x4 trans with 215/40/17's....................my limiter is 7500rpm

 

hi mate


will find out for you but not today tho sorry

The profile is the aspect ratio of the tyre, so to find out the side wall height, you just multiply the width by the sidewall as a percentage, so obviously 40% of 205 is more than 40% of 215 .

Speeds would be:
1st = 40mph
2nd = 70mph
3rd = 107mph
4th = 146mph
5th = 178mph
