Eurospec Transmissions

Does anyone know anything about their transmissions? Maybe I am just too tired to think about it at the moment but, I am going to get a new transmission from EuroSpec. I am THINKING about getting a race transmission. The issue is the gearing. I want it to be able to do good with autocross but I want to take it to the drag strip too.

Does anyone out there have some good suggestions to what the lower gears should be? I think the big question is that should the lower gears be taller vise shorter.

here is their gearing chart: (check out the one that has the final gear getting ya upto 170 MPH. HA HA ha ha)

essencially a high number numerically (i.e. 4.24 compared to a 3.94 final ratio) will give you more acceleration throughout the RPM range BUT you need to keep and eye on drive shaft speeds (if you are a quattro or RWD car) the main reason why is the extra load you are placing on the parts puts alot of wear on the joints ...now in a FWD car its not as bad but you will still be putting more wear on the CV joints N boots because of the excessive RPM you are placing on the parts more often than before

also your crusing RPM will be higher in alot of cases so if your exhaust system is already resonating inside the interior at say 1700 RPM in high gear on the freeway - maybe a simple mellow hum ...you will now have like a 2300 or higher cruising RPM so that hum gets a bit louder - ***RPM numbers are an example***

Another is your gas mileage will suffer a bit since you cruising RPM is changed

UPSIDES - KICK ASS MORE TORQUE N GRUNT OUT OF THE HOLE ....you didnt mention what car you are installing this in or engine combination so its hard to say what gear ratio will work best for what you are doing

I suppose that might help a bit. I am putting it in my 2003 VW Jetta 1.8T. Luckily I am always doing something to it. I guess your right on the 4.24 vise the 3.94. I think I want to get the 4.24 long based on that inforaion. Since I am going to be doing mostly autocross and drag racin for fun and all. It should be good in the lower gears and when I am driving it here and there I should still be doing well on the 5ht and 6th gear.
