Yank has really nice data on theirs,
TCI has little (nice to see efficiencies,
along with the STR & stall, and info on
the materials, clutch, etc.). TCI has
much lower prices from the look of things.
I've seen some people who are happy with
TCI but not much in the way of feature-
for-feature, or road/strip/dyno comparisons
(which you'd have to have deep pockets,
or a shop already full of converters to
do all the angles).


In my case, the Streetfighter (3000/2.2)
would probably make sense, up against the
lower-end Yank lineup (SLP3300, SS3600, Y3000,
many, too many options to make sense of).

Too bad Yank hasn't gotten around to dissecting
some of these TCIs and lining up the specs /
mat'ls like they did with the Vigs. Enquiring
minds want to know (before they plunk down).

 

Jimmyblue,
You may want to ask the Colonel, Terry B., Kristi or one of the other regulars on here as far as driving impressions of the TCI converters.

As far as efficiencies, STRs, clutch matls etc...I can help you there. We tested numerous clutch matls before we were happy with the carbon lining that we currently use. The company that we work with on our clutch linings has a patent on this one and I don't even know everything that it is comprised of. However, I do know that it is an OE grade lining that passed our most stringent testing.

Our Streetfighter 3000 has an efficiency just little over 96% as tested on our converter dyno. It has an STR of 2.2

Let me know if I can help you.

Take Care,
Kevin

 

Kevin, if you could step it up a little, how efficient is the COmpetition 4400 and what is the standard STR of that converter?

 

Jimmy:

Yank will not be testing anymore competitor converters in the near future. The in-car dyno testing used Mike's SS which he sold. Therefore he can not replicate the exact torque curve and drivetrain loss by just borrowing another car.

Yank does use a converter dyno to test their designs, but I liked having access to the in-car dyno testing. After analyzing Yank's results between converter dyno and in-car dyno, I concluded although there was a very high correlation, there was not an exact relationship between the results.

FWIW, the Yank SS3600 is a very nice converter and would be my choice of the 3 listed.

 

Pewter,
The STR of the Comp 4400 is nearly 2.8...It hits really hard off the line.
The efficiency is 94%...It's not as efficient as the Streetfighter 3000, the Super Streetfighter 3500, or the Comp 3800, but it really is one of the best converters for all around ET because of the high torque multiplication and high shift extension. I think Kristi went 1.53 60' on slicks with nothing but gears, Comp 4400 converter, headers and a cutout in her '02 SS.

 

Kevin, what's the STR, shift extension and eff of the Comp 3800? TIA

Anybody know Kristi's ET with a 1.53 60ft?

Nate, Your information is erroneous. TCI has been in business for 35 years. Our quality is something that we take seriously. We did extensive testing on our LS1 converters to prove the reliability and performance of our converters. I've made numerous dyno tests to make sure that the performance is optimized.

Loco, I think Kristi ran a 12.13 @ 110 on that pass.

Onfire, The STR is 2.6, eff = 95%, shift ext is 5300.
Take Care,
Kevin

 

Thanks for the info Kevin. How bad will the 4400 it be on the street with 3.73's? I have a vig 3200 now and it feels pretty tight. I don't mind loose but long as it isn't too loose. I live in a hilly area and is not a daily driver.

 

Pewter,
It'll be very streetable with the 3.73s, but if you're concerned, you may want to tighten it a couple hundred rpm. That will still give you around 4200 stall, but will give you excellent torque multiplication and performance.
Kevin

 

That is the info I was looking for. Thanks for the quick reply...

Thanks Kristi. Thought you had forgotten to respond....WJ. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

I installed TCI Streetfighter (3K stall) about 1800 miles ago. No problems to date..lock-up,etc just right..only regret is not going bigger <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
I would recommed going with the Super Streetfighter (3500 stall)..TCI is the best bang for buck, IMHO <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Sorry for the slow response. I actually joined the real world and got a job so I'm hardly able to get online anymore.

My husband and I have run the TCI 2800, 3500, and 4400 converters in our 2002 SS.

With the 4400, we did indeed have a best of a 1.53 short time (12.13@108 as I recall) on ET Streets with our other mods being 3.73 gears, headers/y-pipe/cutout, and MTI airlid. We have no suspension mods at all. We have about 5000 miles on the 4400 converter and we really like it. To us, driving on the street with it is no problem and the response when you get on it is awesome.

I used to own a 2002 TA convertible with a Yank ST3500 and while the performance was spot-on what they advertised (I ran low 12.60s with converter and gears only), I had major issues with the quality and durability of that converter that never got resolved. You can probably search the board for that whole incident, if you care.

Unfortunately, we were not able to run the TCI 3500 in the same car as I ran the Yank ST3500 in, but based on our *opinions* of the 2 converters, having run both of them in different cars, we believe the TCI outperforms the Yank in both quality and ET.

Good luck in your search <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
