anyone changed torque converter only?

[73duster]

I am curious to see how much of a difference just swapping out the torque converter would make. 1/4 mile, 0 to 60 and seat of the pants feel.
I would think that on these cars a converter would be a bigger difference than most other mods. What do you think?

I know GM High Tech Mag did converter and Nitto's.
The car was also tuned for the converter (which is recommended).

It went from 13.13 to 12.79 in the 1/4 mile.

I have checked into this and was told that, yes, if you have good traction a loose convertor will show great improvements in the 1/4 mile at the loss of some "driveability" and there have been some issues with the lock-up in aftermarkets converters. I was told that the best thing to do to keep things in check with the trans was to have your existing converter removed and reworked for some extra stall and reinstalled. Just my 2 cents.

Have a Phoenix 3200 I'm evaluating for streetabiliy and some 60' times.
*larry, we developed a nice converter with a flash stall of 3200rpm for the 6L80E. It retains the stock clutch and damper so it is compatible with the PWM lock-up strategy of this unit.It is a 258MM size and is nice and tight around town at normal driving.

*no tune
Around town w/paddle shifting it's great. D/S mode + AFM
Just needs a little "heavy" foot from a stop
Highway in D/S mode it's fine.
Tried to get some 60' times, but do to wheel hop and stock tires breaking loose only gained a .10. (BMR trailing arms this week)
Seat of the pants feel

This was Gregs response concerning the GM High Tech Mag article

That is very close to our converter with the exception that ours does not use a billet cover and clutch. We use a stock style damper and clutch to keep the lockup function just like the factory intended and it is also so much easier on the trans and converter since the damper cushions the clutch application.

PWRtrip, what is the price? I have installed the BMR trailing arms and toe rods and my car pulls 1.8's 60 foot times with no tire spin on stock tires @ 374 RWHP. I am waiting on money so that I can do a cam swap but was limited to size due to the stall of the stock converter. Also, do they have any converters around the 2500 area? Thinks for the info and please PM me.

Dave..I believe $589. w/core exchange
Greg is the man to talk to.

*his customer service with the TBSS guys/gals is what swayed me to Phoenix.

Hey, very interested in their converters.

But they have a price of $973.35 for their 4L80E converter. Do they make less expensive converters for the 4L80E?

Quote:
This is our strongest Torque converter for the 4L80E transmission and is available in stall speeds up to 4500rpm and applications up to 900HP. This converter features a billet 1 piece front cover with pilots for GM V-8 engines as well as LS1 style engines. We use a special clutch design that not only has a greater clutch surface area than any other single piston 4L80E converter but will also work with GM ec3 programming. Other features include, full furnace brazing of all internal fins on both the cover and stator, heavy duty sprag and race, full Torrington bearings throughout, hardened hub, hardened turbine spline, anti ballooning plate, fully computer balanced. If you need a high stall converter for the 4L80E then this one can take the punishment! $973.35

*Here is Greg's complete response to my PM request for 2010 Camaro options.
(I just got a hell of a deal with the offer to evaluate and would rather Greg confirm the pricing)
Larry, we developed a nice converter with a flash stall of 3200rpm for the 6L80E but we don't have any cores left to build another one at this time. It retains the stock clutch and damper so it is compatible with the PWM lock-up strategy of this unit.It is a 258MM size and is nice and tight around town at normal driving. We sell these for $589. If you had the time I could use your converter for the build. It would take about two days. The only other option I have right now is a billet cover converter with a non damper style clutch. The downside to this is it is not nearly as street friendly and also costs about $897 Let me know if we can help, I appreciate your interest.
Greg

btw,noticed this converter was 11 lbs. less than stock when I shipped core back in same box.

Interesting. I want a converter, but I don't want to spend big bucks.

Did you get your car tuned for the converter (raise rev limiter, etc). Sorry, I just noticed you mentioned no tune.

I've also been looking into Circle D and Protorque. They seem to have good reputations.
I believe Pro Torque's converter is about $700.00. I know some guys with GTO's that really like the Protorque conveters.

I ordered my Yank 3200 and it was $775 shiped to FL. Waiting for it to get here. The guys at the shop said i should get about 4 tenth off my 1/4.

I was considering a Yank (good reputation) but I heard their converter doesn't lock up in 3rd gear? From what I understand, that reduces top end speed/power. I don't know what else that might cause.

Someone with more converter knowledge could chime in.

[DanD]

you can lock them up anytime really.. its in the tune... As for locking, I only lock mine in 5th and 6th anyway.. maybe 4th if cruising would be ok..

[JS]

I would wait for the updated Protorque 2800

Joe Rivera from Protorque is doing a 12in version (2800 STALL) for me in 3 weeks, He is waiting for his newest stator to come in..It will work and function just like the stock verter but flash stall to 2800...Joe told me he can build me a Custom 10.5 using a billet housing but thinks the 12in (stock size) version will be a great option some of us..

You are correct some of the smaller units will not lock up in 3rd...
Joe is a very smart guy, I would wait for his newest verter..

I will be testing it in about 3 to 4 weeks
Tell him Joel From Injection Connection told you to call him

You can have it lock in any gear the tune will set everything up.
