I thought that there were two other final drives for the 901 trans a taller then stock and a shorter one. If there is a shorter one does anyone know what the ratio is?
Thanks

If there is a different one, it would be for the Sportomatic transmission, I believe. I don't think any of the regular ones have anything but 7:31, and the Sportos may even have had it as well.

yes other r/p sets exist, the sporto is a big source, rare and unobtanioum are the others.
Its easier and cheaper usually to change gears to suit rather than change the r/p and still have the same rpm drops between gears.
Ive been living in a hotel room for the last 2 months, and dont have ready access to my manuals. they are 360 miles away as I type.
You can keep your existng ring and pinion, and shuffle one or two of your exisitng gears, and then source one gearset to make a nice box..
why do you want to change the ring and pinion?

Yep, the other r&p's were mostly used in race boxes so they are made of unobtaininum.

I know about moving and fliping gears but the class I am going to run only allows a final drive change. I might not need one but was just wondering what was out there.
Thanks

Blake,
yes.
Is it a PCA production class?
I know some PCA production 914's in colorado (2 that I know of)
that have a different R/P because of the rules.
I think its the 6:29 you want, but I'm going from memory here.
it will be legal in PCA, and drop all of your gearing.
not cheap.
I almost purchased one once, and chickened out.
count your installation cost too... probably 500 at a lot of shops.

I still have the 6:29 that I bought from Carquip 10 years ago.

I knew there was one. I just could not remember what it was. Chris if do not need the R&P let me know I might be interested. I am in the process of building an ITC 914. Although I do not have a car yet.
Thanks

I have been saving the R&P for a future IT project for myself but maybe its time for me to move on. PM me if you want it.

Have it in your car or have in in your garage? We do still have one of those here at Carquip. It is a NOS unit, and it is far from cheap...
