Is there any reason at all to get the 4.111 gear other than huge turbo, HIGH power HIGH speed runs or more sedate highway cruising? I can't imagine that the reduction in gearing advantage would be offset by more time in boost, other than 1st gear perhaps
edit- thanks also for the information. very helpful!

The 4.111 final drive gear is for people trying to avoid shifting into 5th gear in the 1/4 mile without going to stratospheric RPM's in 4th gear.
For example, AMS is staying in 4th gear to the end, with a terminal volicity north of 170 mph, and if they are on the stock final drive ratio they must be spinning the motor north of 10,500 RPM to be running the traps they are.
Your options to avoid spinning the motor that high are to go to a 4.111 final drive, (drop RPM to around 9,500 for AMS) but that will make the car harder to launch especially with a big turbo.
Or you can go with a closer ratio for 4th and 5th by either using the JDM close ratio 5 speed (8,400 RPM for AMS's trap speed) or the 6 speed from the MR (8,900 RPM for AMS's trap speed) but either of those second two options would require you to make one more gear change to 5th gear in the 1/4 mile. It is a toss up to me what way would work better.... so far people are just pushing the motor to higher and higher RPM's in 4th to avoid the shift to 5th.

Shift into fifth maybe hurt,maybe not.Cosmo run 10.83@127MPH on stock block shift into fifth.Maybe he stay on 4th,he could run 10.6,who know.

ahh...i wasn't looking at the Evo8 gear ratios... with the 9 there's no avoiding shifting to 5th i suppose (with high power levels). Is the MR gearing superior for drag racing then assuming that shift to 5th is unavoidable on the 5-speed (IX)?

The best trans for drag racing is 5 spd from 03-05 EVO!!MR trans is proven to hurt trap and ET!!

Wow, try reading the thread befor you make claims like this.
Up to trapping around 110 mph the 6 speed has the advantage, then in car trapping between 110 and 125 the 5 speed has the advantage, above 125 either the close ratio JDM spec 5 speed or the 6 speed from the MR will have the advantage.

Well i think he meant that comment for MOST people. If you look at the majority of people they are not modifying their evo's to be in the 10 sec range. We all know that for these cars you need to trap about 128 to break into the 10's.
So, for a car that is going to be in the 11's, the superior transmission is going to be the 5 speed.

Gearchart are useful tools, but do not consider the practical effects of the changes to your powerband caused by modifications. If you've substituted a turbo/manifold kit that does not get rolling until 4500+ (read "35R"), then you want to have a transmission configuration that will maximize your time in the powerband, and not be shifting out of it...

That was pretty much the entire point of the gear charts in the original post. It shows what RPM you drop to in the next higher gear when shifting at the stock redline. I offered up the full exel spreed sheet for anyone wanting to see all the info. Personally I shift at 8,000 RPM so my entry point into the next higher gear is at a higher RPM.

Do both the USDM 5-spd. and the JDM 5-spd. trannies use the same synchros?

Ignoring tire size changes due to high rotation speed theoretical speed at 8,000 RPM is 129.8 mph with stock sized tires and gearing.

Excellent post! If the 6 speed didnt seem to have a problem regarding physical weakness, I would seriously consider trading in my EVO 8 for an EVO 9 MR.

Well I know one thing is for sure, when I get my 2.3+GT35R combo... that 4.11 final drive is definitely going in there!
