How much better is Yank SS3600 than TCI SS3500?? Just as it says, i know the Yank is a better converter....but realistically how much would this converter be over the TCI verter? As far as efficiency, track time ET's and MPH, daily driver???

Look at the dates...They are old and before TCI was a real player in the LS1 converters. How many SS3600 do you see on the list?
The Yank is no better than the TCI. The converters are comparable in performance. TCI beats the Yank in price and support.

I agree, you're gonna pay 40% more for the Yank, but with the TCI you get great customer service, and Kevin Winstead on here is awesome. I plan on a TCI within the next couple months

I switched from Yank to TCI and couldn't be happier. There's no doubt Yank is a great converter, but IMHO TCI is just as good at a lower price with great service from Kevin.

Reading a zillion posts in similar threads has convinced me that the performance would be about identical. SS3600 owners seem to report better driveability around town; the TCI might feel a little looser. The biggest difference is price ... I'm not even going to mention the customer support issue.

I saw a TCI from 3 of 2001. I agree TCI beats yank in price and support but what about what matters like effiency? Both are good converters but you get what you pay for.

Yet another Internet myth! Both converters (TCI and Yank) have comparable efficiencies.

I suppose you have a lab set up in your garage? Both are good converters, dont get me wrong. When your drag racing the difference in "compairable" effiencies may be the difference between you winning and losing.

As a matter of fact I do have a TC dyno lab in my home shop! J/k
I base my commits about efficiency on empirical data collected with EFILive running down the 1/4 mile. I know first hand the efficiencies of my Vig 2800 (3.23 gears), Vig3200, a PT4000, and a TCI4000 converter with 3.23 and 3.73 gears.
The efficiency of each converter would vary based on the RPM it was measures at as well as the transmission gear, and rear gears used. At 4500 rpm the 2800 and 3200 shamed the 4000 converters. At 5000 the 4000 were getting better. By 6500 most of the converters were within a few percent of each other.
What good is a converter with 96% efficiency at 6500rpm? Not much because you will spend so little time at that RPM if you are shifting at 6600. I want good efficiency starting at 5300rpm.
The typical 4000rpm converter becomes hydraulically coupled at 1200-1500rpm above the rated stall rpm. 4000+1350=5350. That is why I run a 4000 converter. My cam also starts making good power at 5300RPM.

I bet...All I know is that yank will post their efficiencies on their website. TCI well.....thats kind of a mystery
It seems to me yank has nothing to hide cause they know that they are the most efficientAs for the personal data. Are you sure you were comparing apples to apples? Where they converters the same stall speed, STR, size, and weight? Its hard to compare that way. But no doubt, both are great converters.

My old SS3800 gave up 40 horse, I wouldn't call that efficient. This was a new converter that ended up having bent fins from when it was built. Yank wouldn't do anything about it so I switched to TCI. TCI is an excellant converter, great price, and great customer service.
