No. The MB tranny is made for luxury, not performance. Shifting very fast will cause grinding.

Sometimes I'll get a bit rough with the clutch on take-off. I can do an unaided burnout on dry asphalt without much effort if I let it get full boost before releasing the clutch (Gotta love the VNT! ).

I've done that plenty of times before, especially going into third. I usually pressed the clutch just long enough to get the lever past the synchro but not long enough for the gears to connect.

It's also the worst tranny I've ever tried to shift without using the clutch.

My tran only has 109k on it . However with 2.88 I really have to work it to get even a squeek out. Hopefully that will change with new injectors and PCs. On the NA 300 w/ M pump I could spin wheels until the cows came home and that was 3.07 rear I believe.

Probably a 3.46 like the autos unless MB changed the diff with the manual 300s.

I'd like to try a euro M-pump, crank it up as far as it can go and see if it will make as much or more power than the turbo MW-pump.

Sticks were 346 too.

I remember back when smokey had the hot air engine idea.

When I read his account of it it sounded really great.

He built a car with that idea and offered it to one of the car magazines to test....I think maybe it was a Chrysler k car or one of their earlier little front drivers ....the magazine found it to ping like crazy and not really do that well on economy IIRC.

I really loved Smokey but this was not one of his more successful ideas I don't think.

My Turbo Setup

Hi all,
Turbo 240 asked for some pics and explainations of my setup, so here they are!

I used an exhaust manifold off of a 617 with an adapter plate that blocks off the port for the Fifth cylinder. This is quite easily accomplished. I'm a machinist, so I used a milling machine to make the port openings, but It could be easily done with a die grinder and some patience.

The intake manifold is from a 77 240D with the vacuum controlled Injection Pump. The throttle blades have been removed, but the shafts are still in place to plug the shaft bores. I would have tapped them for plugs, but I didn't want to mess up this manifold just in case I want to use the throttle blades for some reason in the future.

The turbo is off of a 2.2 liter Peugot diesel, so it has the smaller .36 A/R turbine and housing. This works much better than the turbo from the 617 because it spools up much faster.

The plumbing from the turbo to the intake is just stuff I picked up wandering around the junkyard, and I have no clue what I pulled it off of.

The exhaust system was pulled off of a 300 in its entirety, so the flex pipe ect, all lines up just like its on a 300.

Here are the Pics. Enjoy!
Chris
