CL-S or TL-S in stick, Performance guesses?

I'd say w/ the 260/232 combo, the TL-S/CL-S will do 5.5 in the 0-60 stock, and mid-14's in the 1/4. W/ headers, intake, exhaust mods -- bitch pleeeez, just get outta the way.

I rest my case.

Although I have to admit that SS tranny is a quick shifter -- specially in SS mode. I haven't driven a car that shifted faster than this yet (auto).

my guess would be 5.4 sec on a CLS with perfect shifts and a 6 speed tranny.

Not quite that quick. It is very difficult to put FWD cars much below 6 sec 0-60 on regular street tires. With a manual tranny it will be much easier to light up the tires on the CL-S.

A manual tranny should be good for another 20 hp at the wheels with no engine changes, but you probably won't be able to shift quite as fast (most drivers). It would be similar to putting a header on the current CL-S.

Another example would be to look at the current Mustang GT with a 5-spd. This car makes 260 hp/300 lbs-ft and weighs in between 3300-3400 lbs (a little lighter than a CL-S). Depending upon who you talk to, a 5-spd GT will run a 13.9-14.3 and trap between 98-100 mph in the quarter mile and do 0-60 in 5.5-5.8 seconds.

Based on this, with an _appropriately geared_ manual, I think the CL-S would trap between 98-99 mph, but ET would not be as good thanks to poor FWD launch. Figure 0.3-0.4 seconds quicker than the current car which usually runs 14.8 +/- 0.1 seconds. call it a 14.5@98 mph car. Yes, I know some people have gone quicker, but conditions do vary.

I think your right about most points.

Unlike a killer tranny with the box and shift linkage right (or within a foot) of the the gearbox, a fwd car will need a cable shifter, and while they work pretty well (all considered), I don't know if most people (non-pros) are going to get an advantage.

Assume a 5% decrease in loss with 300hp (headers + CAI) -- that equals about 15hp more power.

A 6 speed auto would be very close in performance to a 6 speed manual.

I'd like to see Acura install a "sport"/"adjust-for-conditions"/"sedate" setting to the car's electronic controller to change from 6600-6900 shifts, to 7000 grand+ shifts with really hard transitions with early clutch lockups. It wouldn't be as smooth (that is what the "sedate" setting would be for) as the current settings, but it would optimize the engine and transmission for "hard" and "fast" shifting required for max performance.

We are talking software here -- not a set of parts...

The doc must also point out the extra torque of the Mustang

Some of the really big block torque monsters can actually beat a manual version due to the super fast shifts, and high converter stall speeds, when compared to the equivalent manual version. Some of the Dr's patients can't shift as fast as a really slick automatic.
