I have been kicking around getting a converter for a month or so now. I was originally thinking a Yank SS3200 or SS3600. Then I was leaning toward a Yank PAS3400. Well, I stopped by the performance shop(Lane Culver in Laceys Spring, AL) yesterday to discuss possibilities. He recommended a Circle D triple disk. Prior to his recommendation, I was under the impression that the triple disk was only for true race cars. Now I'm a bit confused because when I searched for triple disk in titles in C6, I get very little info.

Why doesn't the triple disk converter seem to be recommended for a street car on this forum?

Car is currently stock with a Vararam but considering a mild blower cam or just might go straight to a simple centri SC setup. This is a street and touring car but might go to drag strip a few times a year.

 

Triple disc is a lot stouter than single disc. I typically see it recommended for full (max effort) builds and for those who want to shift with the converter locked up.

Don't think you can go wrong with Yank or Circle D. I had a Yank TT2600 in my 475 hp Magnacharged Avalanche and had no issues with it in 60k miles. I have seen more recommendations for Circle D over the past 10 years. I have a buddy who has had a 3000 stall Circle D on his 6.0 swapped, Vortec supercharged Avalanche for at least 8 years without any issues. A Corvette will be much easier on a stall than an Avalanche since it only weighs about 55% of an Avalanche.

 

Before I purchased my torque converter, I had a talk with Circle-D about a single disk vs a multi-disk converter. They told me that unless you are planning to lock the converter during WOT, there really is no need for a multi-disk. The number of 'disks' pertains to the lock-up clutches in the converter. Certainly if you are locking the converter at WOT, you would need the extra 'stoutness' that a multi-lockup clutch disks would provide.

Well, since my C6 is not a dedicated race car, there is absolutely no reason that I can think of to lock it at WOT ... During cruise, as I press on the throttle, I just want it to come out of lock-up as it is normally programmed to do.

However, even if you are not locking the converter at WOT, you can still certainly use a multi-disk converter, but why waste your money on an option that you don't even need.

Make sense ? ?

 

I appreciate the responses guys. I didn't realize that the multi disk converter can shift gears while locked. What would be the disadvantage of shifting while locked under WOT?

If I use my car for canyon carving would the triple disk keep the trans cooler? What about if I end up doing a 1/2 mile or 1 mile event?

 

Unless you plan on making north of 1200hp, just get a good single disc and you'll be fine. You don't need to have a triple disc lock-up if you have an efficient single disc. I ran the pas3400 with north of 900rwhp (unlocked) and the car still had a 32-33 mph backsplit at the track.. I highly doubt a triple disc lockup would've made hardly any difference.

 

I'm convinced you guys are correct. I'm back leaning HARD on getting a Yank PAS 3400. Just a little more research.

 

just too add on the PAS3400 i dropped 4 tenths in the 1/8 and my 60ft dropped from a 1.90 to a 1.62 on the very first outing and i know once i find the sweet spot to launching it i can hit 1.5s that NA with just a couple of bolt ons

 

That's impressive. What tires?

 

MT Street SS DRs

 

19's or did you go down in wheel size?

 

MT 315/35/17s

 

Rybern, the MT 305/35R19 SS tire will go at least high 1.4s. My car when it was a bolt-on went 1.50-1.52 regularly and managed to get a best of 1.47.

 

That's what I'd prefer to do. I'm keeping an eye out for a set of rear GS wheels locally.

I wish I would have purchased the one year old set of MT 325/30R19 that was for sale on here within the last month. Would the 305/35R19's be a litter better?

 

Ever think about using a 305/45 -17 drag radial (lots of sidewall).

Maybe on a 17x11 wheel

 

I'm very open minded to a 17 x 11" wheel if I could find a wheel that would compliment the stock GS front wheels. Having a street set of rears and a separate set of DR's seems appealing to me. The offset would have to look right too. I'm a little bit picky. FYI, I love how those wheels look on your car.

The 305/45r17 is 1" taller than the 325/30r19 so I'm not so sure about that particular size.

 

The 305/35R19 is for the narrow body cars on stock wheels. Not sure what the widebody 19" size are.

 

what size converter was this with?

 

Look for a tire that is close in height to your original tires so no issues with the computer. I have a base, and went with 275-40-18 Nitto R555r2 drag radials on 18x9.5 wheels. Same height as my originals.

 

I agree with that. The wide body tends to make it more difficult without doing custom wheels(which is likely expensive).

 

SS3600. Mods at the time were Vararam, Fast 102 intake, 1-7/8" ARH headers and midpipe, stock axleback, SS3600, B&M 70266 trans cooler, MT 305/35R19 radials and a solid tune from Asylum. Car still had stock wheels, 2.56 gear, stock shocks, etc.
