Is this a good converter? Anyone running it? Any problems or all grins?
Also, should I use this 9.5" verter or go to a 10"? WHats the difference?
DESCRIPTION:
TCIŽLS1 Torque Converter
TCIŽs new LS1 Torque Converter offers an easy way to deliver all that wonderful LS1 engine power to the ground. The TCIŽ LS1 Torque Converter delivers 95 percent efficiency; which far surpasses the OEM torque converter.
Using a 9.5-inch torque converter core, TCIŽ incorporates a heavy duty stator, furnace-brazed fins and a billet steel cover to create a bullet-proof converter that delivers a 2.7:1 ratio of torque multiplication. The lightweight design helps deliver quick engine response and heavy duty mounting bolts are included with every TCIŽ LS1 Torque Converter.

I have a TCI, and it's been ok, but I've been wondering what I've been leaving on the table not going with a better / more respected company. Never had any reliability issues or anything like that.
I will most likely be going with a yank when I get the built trans done though.

Performance isn't an issue with TCI vs. other "big name" converters ... there have been guys whose performance has improved after switching to a TCI from a "big name" converter ...
You really want to dig into the details.
For instance any converter just about, can hit 95%
if you spin to high enough RPM. Each has a slip RPM
that's basically fixed up top and with enough RPM the
slip as % comes down. Point being, you care about
the efficiency -within your shift range- and the %
alone doesn't tell you all you need to know.
Ask them about the clutch and any upgrade options,
I was happy with my 3000 TCI except for this. That
one -delivered- 97% efficiency inside my powerband.
I've seen logs with their 3500 delivering 95% by 6000
and their 3800, less. So it would take some design
changes for the 4000 to be that good, that low down.
Check that they are spin balancing the converter in
question. They used to claim this for all but recently
have seen some folks complaining about vibration and
who knows, maybe it is or is not current production
100% spin testing.
See if you can get from them any converter dyno
info such as, particularly, efficiency vs RPM curves
and torque multiplication vs RPM, RPM-difference.
Just to be sure that the rating numbers aren't, like,
7500RPM based.
