i am hoping to get 4.11's for my auto n/a but how much will my revs increase, at 110 in 4th i am doing 2100revs, how much does everyone else do? My N/A Auto only has a 2 1/4" from the cat back, nothing major

I dunno about in tha VL's man, but I've got 4.11's in my VS and it does 3,800rpm at 100km/h. Shocking for petrol! But bloody awesome for take-off! But if I had an auto N/A, I'd probably go 3.45's. No need to go any higher than that really. Some original photos have not been recovered yet.

They came out stock with 3.45 so id go 3.9's im thinking of doing this myslf but hey 4.11 ok in a manual but auto and ya stuffed for fuel

i did this conversion to my car and stated the before and after comparisons on an earlier post. conclusion now being that im going back to the original gearing

Ive got 4.11s in mine with a 4 speed and it sits at 2500rpm, which is nothing, before the 4.11s it sat on 2000rpm so 500rpm isn't nothing to be worried about Some original photos have not been recovered yet.

Yeah, 3spd is fu#king sh!t! I dunno why the dude before me didn't put in a 4spd auto when he was working the auto, but oh well. Keeps me from speeding all the time anyway... Some original photos have not been recovered yet.

hahaha people put the t350s in cos they dont think the t700 can be strengthened enough, which isn't true cos theres plenty of high hp cars getting around with a 4spd love the car btw dude looks insane Some original photos have not been recovered yet.

1YLDVL, i advise against getting 4.11's, rpm at high speed, speedo, top end loss, the list goes on, the only car i'd put gears in would be a dragster or something that was running low passes.
