I just got my T2 and I had to make a 45 mile drive for a meeting for work!
It is 98% highway and this is the first time I have had a chance to really open her up! Well I got to the usual stretch of highway where there is no place for the cops to sit and then 5th to 3rd!!! I wound the rest of third out and then 4th!!! I never even got out of 4th and I hit 140 mph!!! I have never DRIVEN at 140, it was a huge rush! Especially knowing that I had ALL of 5th left!!!
I just wanted to share my happiness with the fourm!

DCmina

cool but watch out when downshifting! :O

Matlock

Sweet! I wish my N/A could hit 140 that easially. That's my top speed, no more left! Downshift to third, I also wish I could do that, transmission isn't in the greatest of shape.

SaabGuy

140?!?!?!?!? Woow. My 87 tII can only hit about 125mph in 4th gear. I guess the s5's have slightly different ratios??

Sweet ride man. What are the mods??

KenshinFC

do you have an S5 or S4? The S4's only hit 125 in 4th gear? Are you sure? I have an 87 TII also but I've hit 135mph at the end of 4th gear.

Yeah, be careful downshifting so quick. The tailend could slide out on ya. I took my TII up to 145mph... then I got scared. I don't have THAT much ***** yet..

Nearly all 5-speed cars have a 1:1 4th gear ratio, and an overdrive 5th gear. This includes all manual transmission RX-7s.

Speedometers CAN and DO get misadjusted over the years .

WOW!
Now I see why so many people want an S5!
SheeeeeeeT!!!

4TH GEAR NOT 5TH RE-READ THE POST!!!

there's no way you hit 150mph @7000rpm in 4th gear

UniqueTII

Frank, you about ready to start driving your TII again?

gz91rx7

So do you mean that 5th gear is only going to lower my rpm's? There has to be power in 5th!

NZConvertible

Sorry to disappoint, but that wasn't 140mph. Top speed in 4th on stock diameter tyres is 121mph. You cannot trust an 11yo speedo near the top of its scale. He didn't say there wasn't, he just said it's an overdrive. For a Turbo, 5th is 0.762:1, so 5th will produce only 76.2% of the power and torque as 4th at the same rpm.

gz91rx7

Well I thought it was strange but I doubt that my speedo is off THAT much!! I will have to have it checked out!

BlackFC_NYC

do you have any pics gz91rx7?

VetteKiller

YES, Friday!!!!!!!!!!11111111

or I will beat Mark up

gz91rx7

Yeah I do but I cant post them! There is one under 2nd gen forum. It is in my post of my new T2 FC

BlackFC_NYC

hey where do you live in north jersey?
your rims look like mine kinda, i have(had one the car) koing monsoons.

looks good..

peejay

Wow, someone else who doesn't believe the numbers on the dial!

Speedos are USUALLY set to read too high ("optimistic"). I've heard of new BMWs where the speedo reads 40 and the actual car speed is 33!

peejay

That's only 17% off. Actually, that sounds about right...

Bambam7

Not sure if the gearing is the same, but at 8000 rpms in my N/A S5, I get about 215 km/hr. That's 133 mph.
That's also 8000, not 7000.
Not sure if my speedo is dead on or not either.
