No idea, but I think you'll be 1 minute faster on the Ring....

 

Hey dutch....you have the JDM final drive....whats the max speed your tranny will take you to? I hear it's 115...is it true? If so would the GSR 5th gear help? Making my final decision on whether or not to get one thanks

 

I have the complete JDM gearbox, so the 4th and 5th gears are longer. I can reach 240 km/h (150 mph) @ 8400 rpm indicated....

 

Pm me dutch if you dont mind so i can get some more insight....i just dont want my car to max out like at 115 like i hear...

 

Maybe Yoshi put the gear ratios in his FAQ?

If you put an JDM final drive in an USDM gearbox, your revs will increase with 4.785/4.4 at a certain speed...

So, if you were hitting the rev limiter (8600 rpm) @ 150 mph with your USDM gearbox, you will reach 138 mph @ 8600rpm with the JDM final drive.

4.4/4.785 * 150 = 138....

Kool....thats exactly what i wanted to know...the GSR would help me keep some of the highway driveability too huh?

 

I have this setup you are asking about, but I suck at drag racing anf i live at 5000 ft Above Sea Level. My last times were:

1/4: 15.04
60": 2.34
1/4 MPH: 93.5

That was on 205/55/15 Dunlop W-10's
Some people have told me that my car is faster then 14's, perhaps 13's at sea level???

use this. FYI put in 23.1 for tire diameter for a 205/50/15.

You can change the Findal Drive after picking your tanny and you can see what your top speed ill be. Make sure to change your redline to 8200.

 

"Approx. 1/4 mile time w/ JUN 3's & Jdm Final Drive"


low 13's with slicks

 

115????? yeah uhh do some research before you just spit out numbers. I have the ATS 4.929 and I can get up to 147 indicated. So uhh, how the hell does the JDM LOSE top end? It doesn't thats how

 

actually the JDM FD with an ITR 5th would lose top speed by a little. just normal for the gearing. it isn't 115 though

edit:

USDM R 5th with USDM FD = 156
USDM R 5th with JDM FD = 146.6

Just to give hard numbers, but hardly 115 which is some serious false info.

Like i said...what i've HEARD....so before you start acting like an ***...read the post first....dont know much about the jdm final drive...which is why i POSTED...i was tellin you guys what i had HEARD i was trying to confirm....i figured the 115 number was wayyyyyyy off...it sounded ridiculous...next time time dont be an ***...UHHHH uhhhh

 

I don't think any of you fools should be hitting 150 mph anyways. hehe.

**oh yeah** ...and to get back ON TOPIC, I would say your car would run low 13's on slicks also...assuming that proper tuning was done.

arbi..man, cant you take 2nd place....???

now that henry got his hatchcrap, you wanna have the upper hand huh??

Well I would say with that set up maybe low 14's or high 13's with full interior and street tires. I guess we;ll have to wait until september to find out
