I can't say since I've never dealt with traction control.
Howard wants to break the sound barrier. Taller the better as long as the car gets moving.
I don't so no worries.
Tire slip is a variable, but not one that shold be dismissed. Under acceleration, there is more slip at slower speeds vs. higher speeds. The opposite is true for braking. There is little to no slip at zero/balanced throttle. If you are trying to gear a car for a specific speed/rpm out of a corner (or whatever), discounting tire slip can and will yield less than desirable results. Granted it is also a theorarical speed as is not accounting for it, but it is also a more accurate estimation.

Competitive race teams, be it on a road course or drag strip will always account for tire slip when gearing a car for a particular track (or 1/4 mile). The competition is usually too close not to and would be foolish to dismiss it. There are methods (i.e. software/hardware) for accurately estimating tire slip. You can even end up with negative tire slip such as with tire growth. Think of Top Fuel dragsters.

The important thing is as you stated though, just keep all variables the same when doing comparisons. I agree it is not necassary for street cars or for most of us but you have your way, I'll keep mine.

 

If anyone is interested I was quoted a big discount for an order of two PPG gearsets and an even bigger discount for three or more. Realistcally I'm just hoping one other person is game as I think more than that is a tad bit optimistic.
The set includes both input and output shafts, gears/dogs, billet shifter forks.

-----------------AUD-------US---
List price ---$9000----$6975
Two sets ---$7995----$6255

Shipping is about $200 (US) a set.

Ramy, c'mon dude....

 

Would you guys be interested in a turbo II transmission with dog gears?
I can have a complete tranny with ratio's of your liking installed for alot less then the cost of ppg gears..

 

I see our friend has finally delivered.
Does it have the xxxx input and xxxx mainshaft?

 

300m..

 

hey, i have a 20b fd and am interested. pm me

 

I have a 20b fd. im interested. pm me

 

My only reservation is, if the FD case will flex under great stress (high hp applications), what will prevent the FC Turbo II case from flexing? Isn't it made of aluminum as well?

 

I was thinking the same thing.

 

interested

 

check your pm's

 

Another cool gear calculator.

I paid $6500 installed in my case from Andrewtech Automotive in Gaithursburg Md. Ask for Andrew....240-683-1000

 

Just curious why everything has to be so "secret". If we are all in the same community/family, then what is there to gain in keeping it to yourself? This applies to everything, not just this topic.

 

No 6th gear or graphing functions.
I do like the slider though.
I'll be contacting him.
That is a great price, especially considering the PPG gearset you got for your stock mazda case lists for $500 (AUD) more than the Supra 6-speed set. That is also weird since the mazda set only has 5 vs. Supras 6 gears and does not include (except by request like you did) input and output shafts.

fwiw, if I decide (likely not) to use the stock case, Enzo quoted me a much better price and with a (claimed) wider range of ratios and parts availability.

 

What gear set? PPG?

 

What secret?
I was asking as to which components were being used and Enzo promptly replied.
No secrets there.

 

Carefull.
Ernie does not like people holding out on him! So you better quote that price Enzo gave you or else!

 

IBTL (j/k)

 

This sounds pretty cool and we know Carlos can deliver

 

Just took delivery of my Getrag and Supra aluminum driveshaft for $1800 shipped

 

ok so i read the thread and the supra trans sounds like an awesome idea. i wasnt sure which gearsets were put into the calculator but what would be the RPM with a supra trans in an FD with 3.90 rear @ 70MPH in 6th gear? with both the V160 and V161?

 

'Yo

@ 70 mph. on the 3.9 w/ V-160 & a 25.4" tire : RPM = 2853

same as above, with the V-161 RPM = 2954

 

Where did you get a Supra tranny so cheap? They're $4500 new.

pm me if you want the username of the seller.
He shipped quick and was very straight forward. He said he occasionally comes across them.

The tranny is not new and is in need of a rebuild. That is pretty much the going rate for them in said condition. The seller made clear it is drivable but didn't recommend installing it as is.

I am installing the PPG gearset and would only do so if I could source a tranny in this condition.
