I picked up a TCI Super Street Fighter 3500 Torque Converter and was wondering if anyone can tell me what to expect on the street. how loose is this converter? How will drivability suffer, I live in the DC area and Traffic sucks.

My Mods are:
JLT II CAI, Steeda CMDP, Steeda UDP, JBA Long Tube Headers, JBA Catted H-Pipe, FRPP 4.10 Gears, FRPP GTA Mufflers, Spyder Aluminum DS, CHE LCA.

 

Drivability will not suffer at all, and actually makes the car easier to drive as it won't need to downshift so often when you lean into the gas pedal (as the converter will flash up).

Check out the video of my 07 GT by clicking here. This was filmed several months ago before installing my supercharger and the converter was flashing at 3,800 rpm's then (just a few more than your TCI 3,500).

Notice when I first take off slowly in the parking lot that it doesn't rev very high at all (much like stock making it easy when driving slow in traffic). When I turn right onto the street, notice how it revs up a little (I'm only giving it partial throttle), but that the revs don't really drop much as it shifts. Then as I take off from the stoplight, notice that when I floor it how it revs instantly and when it shifts from 1st to 2nd how the the revs don't drop at all.

If you click here, you'll see my 07 GT on the dyno. The dyno pull was locked in 4th gear. This video is with the supercharger on the car. Stall converter flashes to 4,800 rpm's now (more horsepower will make a converter looser). If you listen to the car rev, it doesn't sound like it's changing much, and it isn't as it flashes to 4,800 rpm's and climbs to 6,400 rpm's during the pull, so it's only spanning a 1,600 rpm window. However, that wide open throttle pull starts at 74 mph and goes to 114 mph, so even though there's only 1,600 rpm's, it's a full 40 mph of acceleration. That's because the transmission and rear end have to catch up to the flash speed (4,800 rpm's) before the engine needs to start revving any higher. In a stick shift car, you would hear the revs go way up as rpm's and speed increases, then drop way down during each shift. Whereas a big stall converter almost sounds like a car with a CVT transmission.

At the dragstrip, I improved my 60' time nearly 3 tenths of a second as it launches so much harder! Unlike a manual trans, when my car shifts there is virtually no rpm drop during gear changes, so you are always in the peak power range! Definitely one of the best mods for an automatic car.

 

Oh, worth noting, when I had my car custom dyno-tuned recently for the supercharger, I also had him custom tune the shifting (100 psi line pressure & 6,400 rpm shifts in "drive") and torque converter lock-up. The factory lock-up in 4th and 5th gear helps with fuel economy, but we set the lock-up to happen sooner after a shift to get full power to the rear end even quicker (1 second instead of the much longer factory settings). Also turned on lock-up for 3rd gear, as well (1st and 2nd gear can be locked up, as well, but most tuners don't recommend that - gotta keep the converter looser in low gears to get the mass of such a heavy car moving first).

 

My Tuner is Doug from Bamachips, I will pass this along to him.
thanks for the info

 

I've heard all kinds of great things about Doug. Too bad he's 2,500 miles away from me! Our local tuner is very well known, though, and specializes in late-model Fords.

 

Doug came to Fairfax Virginia last month and did a dyno day So I got a very good tunes
