Useable reverse, built in PS and tranny pump....... sounds like you should just put the name Fortin on the side..... Sorry..... bad joke.
All are units have useable reverses for the correct application,and the larger units have PS and tranny pump options. Did you know that? "sounds like you should just put the name Fortin on the side" HA HA! But your right. People dont realize that most gear boxes are older units just re-engineered with new names on the side. above case in-pointYeah, reverse in a VW car on the street.
Lets not beat a dead horse.Yes, I do know the larger units have PS and tranny pump options, but this thread is about the 2D. You can put a tranny pump on a 2D, but you can't run your PS off of it.
Yes, we can do this, but now the dimensions have changed and your tire size has grown beyond the
size of the driveline.
I don't think the Fortin is a re-engineered box. It has had upgrades over the years.
It started life as a Hewland DG300Your suggestions are Good.
What would you say the standard car the new gearbox would be going in, would be?
weight,tire,power,ect.I personally don't like the PS off of the tranny.
I see no need for it toBut for your other question, I would say a 2500lb car on average.
2700-3000 is what I have seenI think peoples cars are heavier than they realize.
True450HP pretty standard.
33 or 35" paddle.
Alot of people are going to 17" wheels.
You also have to take into consideration CV size, axles and hubs.
I run 934's with outboard hubs. That adds alot of weight and alot of centrifugal force is spinning. This can be hard on a tranny as well.
I disagree the reason 935 are used is strength in a larger axle for the larger tire beign ran. The tire is the force that has to be dealt with.Below is how we currently rate the MD4S/ so your not far off/ I agree people are unaware of cars overall weight. This and tire size is what eventually put the hurt to the MD4S.

1300 Padla-Trak? That's your recommended max tire? If that's true, everyone with a 2D is over limit.
DING , DING, DING, WE HAVE A WINNER!!!!
DICK TELL HIM WHAT HE'S WON....
All kidding aside, the MD (Medium duty) box was never designed around the use in heavy four seater cars with v8 engines that put out what they do now a days, and the size tires now being used. It was designed around the needs 15 years aggo before everybody went big, tires, cars, suspension, and motors. That is what the S4, S5, S4D and S5D are for. If your putting out more then what they can hold then you go to the Big momma, the HD4....... That just the cost of going big..... You know what they say go big or go home!!!!! This just doesn't apply to the MD
This is just our ratings, we have seen many people make the MD boxes last behind big HP for many seasons. You just need to know how to take care of your equipment, and for god sake push the clutch in when your in the air and don't let it out untill your tires are planted back on the earth......
