anyone run the 1/4 have to shift to 5th, or have you done it? just curious how 5th gear would act in the 1/4 mile or in a street race that wont end.
flame me, im just curious.
thanks.

 

ive heard of people on here recently talk about it, but the owners who had to do it had 4:56's installed...like they said it sucks cause its hard to shift into 5th gear pretty fast. thats what i heard

 

yea, just try shifting to 5th fast (done it when i took mine up a wee bit over the speed limit )
it's not the easiest thing to do
as long as you don't do 4.56s for gears, you won't have to shift to 5th in the 1/4 for the most part

 

I have the 3:42 gears and I barely made it into 4th.

 

4th gear does about 130 on my LS1....stock gears...

you really gotta be moving or short shifting to need fifth.

a street race that goes over 130 is just plain stupid unless it's on a closed track/road race.

 

4.11 rear and I'm still in 4th through the traps.

I figure that by the time I get to a high enough trap speed (115 ish) to require a shift into 5th, I'll have already installed a cam and done valvetrain upgrades that will allow me to rev higher, and not have to shift into 5th.

 

I'm able to shift to 5th pretty fast

 

thanks for your posts. i am in need to see if 5th gear would pull in a race, or its too much of a drop in ratio(1:1 4th vs. .74 5th) to do any good. im gonna have 4.11 gears, and im afraid i wont be revving high enough to make it in 4th.

 

Yeah that's about right:
At redline I'm pulling (W/ stock gears)
1st=45mph
2nd=70
3rd=110
4th=?
5th=?! (!Keeping my eyes on the road!)
6th=?!?!

Don't want to start a new thread but what's the trick to launching with the M6? I've heard 2100 RPM but, what happens with the clutch action?

 

5th=~165 (tested ), not redline yet though
6th<5th

 

Back when I was running 4.10 gears, I had to shift into 5th before the end of the quarter mile. It will definitely hurt your times; you're not accelerating while you're shifting and the car won't pull as hard in 5th gear as it's an overdrive gear. I recommend changing your gearing; you could also go to a taller tire (28") at the track.

 

thanks^^^
asking this for a friend. we are putting a small block stroker with nitrous and a 6 spd behind it.
its only gonna weigh 2700 pounds, that may help pull 5th a lil better.
a 4.10 is the only gear option available for an rx7, other than custom gears for 599.99 + shipping.
a 28" tire is a nono. there is barely room for a 26". dont wanna do any cutting just yet.
thanks again for the reply.
