Whens the last time you saw a restrictor plate on the end of an exhaust to increase backpressure. Just because backpressure goes up on a more restrictive exhaust does not mean its the reason the engine makes more power. That would be like saying that radiation is good for you because its in the...

That would be harder to match, then. Not sure how I'd do it.

Foot flat to the floor, it shouldn't make a difference theoretically. Otherwise, most scanner show TB position %, you could try to match that as close as possible.

Well in that case, you're just flat out wrong. Backpressure is bad. https://motordyneengineering.com/scavenging-and-the-exhaust-backpressure-myth/ "Back pressure rapidly reduces performance. The butterfly valve was attached at the end of the Y pipe and dyno tested at various levels of flow...

This isn’t back pressure, you’re thinking of scavenging.

Theres a very simple solution to this. Plug a scanner in and read the live data. Record the same exact pull in normal, and track. See if the recorded days changes timing

False. Backpressure is bad, period. What you're thinking of is scavenging

Back pressure is bad, and not something you want. Scavenging, on the other hand, is good.

Lmao, I’m not going to get a dark horse. Trading into a used car with an unknown history (how it was treated) is a far bigger risk imo than dropping 3-5K on a new transmission and selling the MT-82 on ebay to recoup some of the money.

If you can feel that extra 6 horsepower, you're probably a wizard. No shot.

Are you running lowering springs? The stance looks real good

A magnum on the S650 would be superb. I'll do some digging, I know theres some S550 writeups.

Nah, the whole point of getting a stickshift in this day and age is to shift. I want atleast two or three flat out shifts before I'm breaking any laws, hahah. Mustangs have always sort of been the American tuner car, comparable to the Hondas, or Nissan 240SX in my eyes. Half the fun of these is...

I just like closer tighter ratios, and the tremecs also feel nicer to drive. Driven a few before, I suspect DH feels similar. If it were up to me, I'd have the car max out in second gear at 62 mph, but thats just personal preference.

Thats the thing, I don't know if the ECU needs any sort of reprogramming or relearn for a transmission swap. I don't use rev match, so that in particular wouldn't be a worry.

My thoughts are, well, how hard could it be? Maybe needs different mounts or something. my biggest question would truly be regarding whether or not the ECU would get fussy with communications. At the end of the day, its just a stickshift, right?? I fondly remember doing tranny swaps in TR6's...

Yeah, I looked it up, same rear ratio. half the reason I'm looking into this is so I can have tighter ratios, other half is for the tremec and a little less rev hang with a few lbs off the flywheel. Nothing crazy, but just enough to make a difference.

Don't both the DH and the PPGT have the same rear? Pretty sure the DH has a 3.73 final drive, right?

I can't imagine its *that* much work to justify trading into a different car. The transmission will have to come out for a clutch replacement eventually anyway.

I'd be tightening up the gear ratios over the stock MT-82.
