The ones that have changed to the 373s did it make a noticable differance and the ones who changed to 410 do you regret going that high, did it hurt your performance.

I had both 4.10s and 3.73's. I'm running the 3.73's now, but I dont' have any track data of before and after the change. I just thought the 3.73's would help my ET's. Only data we have is ET's from Scrming, Black LX and I.

Scrming best run on Nitto 450's with a 100 shot is 13.4
My best run on Pnero (which suck!) with 100 shot is 13.6

I have a set of Nitto 450's enroute as we speak. However, our cars are not setup the same, so it is hard to tell what the real difference is. For example, his car is setup for TQ, with 100 shot, he was at 255rwhp and 385 rwtq. My car with 100 shot is 278 rwhp and 362 rwtq. Real difference there is I have an X pipe and duals. Not sure if that is why my numbers are different, because I spray later than him.

Jimp/BlackLX is 271 rwhp and I think 345 rwtq and he is single exhaust with Magnaflow take off. But I think he sprays at 2500 rpm like I do.

Hard to say really. Personally since you do not want to rev past 6k when using a power adder, on the 1/4 that 4.10 is mighty tall, I would rather go with 3.73.

Just my two cents.

3.73's have made a very noticeable, ear to ear grin difference. I wouldn't want 4.10's on my ride...at speed, rpm's would be too high for my taste.

scrming

as other have said.. the 4.10s are not for everyone... LOL! I'm running 4.10s but I'm also running a taller tire in the back.. almost a whole inch taller! so that makes the 4.10 more bearable... but for getting of the stop light quick... 4.10s are a blast! LOL!

if I had to do it over I would probably drop down to 3.73 or 3.55... but since the 4.10s are already in... i'll keep them.. LOL

3.73's made a real noticable difference. Although I am still breaking mine in, I can feel that the car just wants to go now.
The rpms don't drop as much in each shift now either, so it also feels faster due to not having to climb to the powerband on each gear when accelerating.

I have to agree with John on the 4:10's. In terms of acceleration, they're hard to beat. I have an automatic and when I'm cruising on the interstate I'm only turning around 2300 RPM at 65mph in final drive, so my vote would be to go with the 4:10's.
