That’s pretty much what I’m looking for! I’d order for an s550 especially if you could do the boss 302 lettering. I’ll send you an email.

The tremec itself is 90% of the difference. I should not have driven the dodge because now I’m hell bent on ditching the mt82. The tremec feels exactly like my old ford top loader 4 speed which I love.

You have the temec though. Big difference in that setup from my mt82. I have no doubt ford has the tremec set up better than dodge does. They sure as hell don’t have the mt82 set up correctly from the factory though. My short throw mt82 shifter is still a longer throw than the stock dodge. I...

Anyone know where I can pick one of these up for an s550? seems they were made for a bit but I can’t track one down. I have a vague recollection of this being posted recently, maybe even by me, but the search is failing me.

Yep not abnormal. There is no sound proofing above the trans in these cars. If I ever drop my trans I will line it with dynomat.

Done. TonyNJ hooked me up with one. Clearly a major improvement in the factory clutch. Still nowhere close to the dodge clutch.

I am tuned. It is removed. The car still “learns” some rev hang once the ecu completes its 200 mile relearn after the flash. That’s why I think it may be tire size related because the car isn’t sure where to hold revs between shifts. none of that negates the 8” clutch throw, 3” long friction...

So I just drove my boss’s 21 scatpack manual. That thing drives with 0 rev hang. You actually have to keep your foot on the gas between shifts to stop it from dropping too low. I can shift that car just as fast as an automatic. And the clutch is an appropriate length, not 8 inches of travel like...

What it seems to be doing is hunting for the right Rpm. Mostly it rev hangs, sometimes it drops the revs too far. It basically has no clue. But it will sit the revs at a set rpm if I stop mid shift so that’s clearly what it’s doing. I just drove to lunch and verified that.

Yeah come to think of it I bet it’s the tire size issue. Time to go to work in forscan and see if I can get the pcm to relearn it before reloading my tune.

Stock diameter is 27.7. I’m at 26.2 inches. so it’s about a 150rpm difference at 70mph in 4th.

That would make a lot of sense. My tune does kill 90% of the rev hang, 99% of it until the computer relearns my driving habits. If I shift like Steve McQueen while it’s learning it stays with no rev hang for quite awhile. part of the issue could be rear tire size mismatch with the pcm. I’ll...

It’s not tune related the car had horrible rev hang stock. It’s much better now with the tune. I think it’s rev match related. I’ll have to try toggling it off for awhile.

Yeah E85 saves me a shift change pretty often on the track. Some corners I would have to shift into two now I can keep it in 3.

Someone tell me if this is just in my head. In normal exhaust mode, the revs hang longer on shifts so I have to shift slower. in track exhaust mode (wide open) revs drop immediately. this is not drive mode dependent. Am I imagining this or has anyone else experienced this?

The true work around to this is PCMtech tuning which can individually select throttle maps and suspension modes iirc

Neither. I have no real opinion on rod ratio. I will admit I’ve used that term incorrectly throughout this discussion when I really meant bore/stroke ratio. I think a longer stroke allows an engine to produce more torque at a lower rpm than an otherwise equal engine of the same size with a...

Since neither one of us is an expert and apparently this is something the experts disagree on, we’ll have to agree to disagree. This is probably the most fair article I’ve seen on the subject https://www.enginebuildermag.com/2016/08/understanding-rod-ratios/

This is absolutely not true. https://www.hpacademy.com/technical-articles/rod-to-stroke-ratio-explained/

Not arguing with you there.
