crusing or brusing??

[pelvins]

not sure what to do about changing my diff ratio

2ltr 15 in wheels

current :3:5:1 low revs at 70 mph good for trips to ford fair etc

 

or :3:8:9

 

better for acceloration and wiping the smiles off faces ?????

Paul, go for acceleration unless you feel like tailing all the mercs and audis as they come flying past on the motorway

Gotta be worth trying the 3.9 and see how you like it

3.9

[DEP]

I run 3.75 in mine, still good enough for 140

[LEONMEX]

i ran a 4.4 in mine for ages but at 70-80mph for 2 hours to pod was not good so swapped for a 3.89 & it was perfect for the road & still ran low 13's at the pod. Going for a 3.44 in my atlas though as i fancy 150mph

Ditto going for a 3.44, was getting near max revs in 4th with the 3.75, got a 3.09 in the wings if necessary!

or put some bigger wheels on,or bigger slicks you will gain around 10/12mph in 4th

Im on a 3.75 but have a 3.44 in the garage which i may try one day. Done 164mph on the 3.75 in 5th gear. But at pod im usually going across the line on the rev limiter in 4th at 130-132mph with 13" wheels on it. With 15" wheels i do around 138-140mph in 4th.

4.6 in ours

cheers people i think i will try the 3:8:9 unless i get a 3.75
