Wayy too short.

Discuss.


Slow today so I am trying to get something going.

Not sure of the MS3 tranny, if it's the same ratio, you discuss also ;-)

I don't know anything specific but I kinda thought 1st was short in the ms3. Kinda just enough to get the wheels moving so 2nd can do the work. I still love her passionately tho...

Agreed.

Further discussion is needed ;-)

Each have the same ratios.

you just need 9000rpm redline like the 8

MS3:
Gear Ratios
1st 3.538
2nd 2.238
3rd 1.535
4th 1.171
5th 1.085
6th 0.853
Reverse 3.831
Final Drive 1-4th: 3.941
5-6th: 3.350

MS6:
Gear ratios
1st 3.538
2nd 2.238
3rd 1.535
4th 1.171
5th 1.085
6th 0.853
Reverse 3.831
Final Drive (1st-4th / 5th-6th) 3.611 / 3.095

They do have the same gear ratios.

My poor 2.3 just shivered. Imagine the sound of the 2.3 at 9k. Like a bag of screaming babies. (Sorry just for reference, I don't condone babies in bags.) Cats on the other hand.

I keed, I keed ;-)

Thank you Sir.

Of course a 9000 redline does little in first gear for an 8 considering a good launch is ~5.5k and shit is ~7.5k. It's really not much different than a 6.5k redline where you launch at 4k.

Probably the other Speed6 guys can only really chime in... In the Speed3 1st and 2nd are more limited due to the possibility of torque steer in FWD. I don't usually get on it hard in the first 2 gears anyways as my "encounters" occur at 3rd and above from a roll.

Thank you Sir.[/b]

No prob but I just noticed the final drive ratios are different. WTF?!!!

Doesn't the MS3 ECU limit power in 1st gear anyway?

Now THAT made me laugh!

It's true the Speed3 & Speed6 have the exact same gear ratios, to include final drive ratios & tire diameters. You think those gears are short though, the STI's are even shorter lol. The ratios for a Speed3/6:

1st-4th gears Final Drive ratio is 3.941, ratios are as follows:
1st- 3.538
2nd- 2.238
3rd- 1.535
4th- 1.171

Final drive ratio for 5th & 6th (gears on seperate shaft) is 3.350, gear ratios as follows:
5th- 1.085
6th- 0.853

With 6700rpm redline, & stock 215/45/18's, max speed in each gear should be:

1st- 36.6mph
2nd- 57.9mph
3rd- 84.4mph
4th- 110.6mph
5th- 140.5mph
6th- 178.7mph (<<<Assuming it actually had enough power to reach theoretical top speed)

Although, in stock form, at this altitude, power drops off around 5000rpm, so shifting at redline is almost pointless in all gears except maybe first only to take advantage of torque multiplication.

In contrast, here are an 04-06 STI's gear ratios:

Final drive is 3.90, gears as follows:
1st- 3.636
2nd- 2.375
3rd- 1.761
4th- 1.346
5th- 0.971
6th- 0.756

Top speed in each gear, with the STI's 7000rpm redline (300rpm higher than the Speed6's) & 225/45/17 tires:

1st- 36.7mph (<<<Notice, it's almost the same MPH as the Speed3/6 with a 300rpm higher redline, short gear )
2nd- 56.1mph
3rd- 75.7mph
4th- 99.1mph
5th- 137.3mph
6th- 176.4mph (<<<Again, assuming it had enough power to reach theoretical top speed)



Then again, cars like the Speed3/6 weren't made for drag racing lol. Short, close ratio gears are GREAT for autoX/track events, helping to stay in your powerband coming out of corners.

Hey Brendon, what RPM are you shifting at in 1st? I agree it's a short gear, but if you're short shifting, just getting a tune will help a TON with giving you a much wider (i.e. more usable) powerband, and make 1st more useful.

I know, but I wasn't calling you out on it. I'm still a Noob ;-)
