LS3 A6 car, headers and a BTR Red Hot cam. I don’t have any experience with TCs so forgive my ignorance. I was told this cam would be mild enough not to cause a lot of bad manners as far as drivability. It’s really on the edge being basically a stage 2 cam. Tends to push through the brakes which is my biggest and really only complaint about this cam. Would a TC help eliminate that? Is the cost be worth it (no clue to the cost). What other gains should I expect! Appreciate it.

 

A torque converter with a higher stall speed should help. It would allow the engine to spin more without engaging the transmission. I'm not familiar with your cam so I don't know what particular speed you need.

 

I have a 3600 stall Circle D in my otherwise stock '06. I can almost sit still with out my foot on the brake. I'd say that would help you out. Also took about .4 off my 1/8 mile et.

 

3600 seems extreme on a stock LS2 considering the stock converter is 1600. However, 3600 may very well be perfect for op.

 

absolutely a TC will help go with a Yank or Circle D converter and unless your into hardcore drag racing a 3200-3600 is perfect for your set up and will alleviate you pushing the brake issue

 

It took some getting used to but I like it. Really good at the dragstrip.

 

So I have a similar problem with a LS3/4L60E in my 80 Camaro. Cam specs are 225I 230E .610 lift 114 C/L. Yank 2800 stall 11" converter. Not billet. Bought the converter about 4 years ago. But I did not consult with Yank since I've used the same cam with a couple of other LS swaps but with manuals instead of autos. Should have. Great cam. Just a bit of chop but very street able. No issues with power brakes.
Spoke with Yank today and they said their billet 9" 3200 stall converter would cure my pushing issue. The down side they are a touch over $1100 plus install.

 

A converter will definitely help. The correct converter for your preferences will make a big difference. I prefer a "tighter" converter rather than a "looser". Meaning it doesn't slip as much during everyday driving, so the car drives "normal". But, step on the gas quickly and it flashes to the higher rpm. You should also plan to get a transmission tune to get the most out of the converter and tailor the shifting to your preferences. Call Yank and Circle D, discuss your car's details and your wants, and they will get you lined out.

 

I have a Yank 3600 stall in my ls3 car with a TSP F35 stage 4 cam. It drives fine with the large stall. and can run 70mph at 1500 rpms

 

It really depends on what you use the car for. The point of the aftermarket converter is to get the car into the correct spot in the power band. With modern converter technology and tuning, a rather loose converter can still drive fairly tame. It's not like a TH400 with a 6k stall and no lock up where the car has to flash to 4500+ just to get it moving at the speed limit. With the 6 speed autos and proper tuning, you'll be shocked how smoothly a car can drive.

I've done two C6s the owners are friends. They race each other, both have the same, same headers, same year, same gears, same tuner, they make about the same power +/- 5, depending on the dyno pull. One has a stock converter, and one has an aftermarket converter. They both drive pretty well. The aftermarket converter car feels a little better to drive, and it's quicker. Every race ends the same they take off, and the converter car jumps out about 1.5 cars, and then they hold that spot the whole time.

The key is getting the right converter for the car. I've gone from running high 10s to low 10s in my c6 with only a converter swap. One of my friends didn't want to get a "loose" converter for his cammed ls3, he ended up getting a "2800" and the car had a slower 60ft than it did on a stock converter, it drove decent, but it couldn't get it to the power band right. We ended up going to a looser converter, and that car drives so much better now and dropped almost a whole second on the 1/4 in similar conditions.

Here's a video I did to try to show a real world difference between a stock converter and an aftermarket converter.

 

Converter is the most important part of the vehicle.
It can make or break any combo.

I only use triple disc Yank anymore in V8 applications. Most of my customers prefer to stay in lockup cruising onthe highway when transitioning to wide open throttle, there are many benefits to triple disc in this way.

The cons to a quality converter are few, but here
-slight decrease in fuel economy out of lockout , barely noticeable on some vehicles though.
-Very expensive part is at risk if anything happen to the trans = trans + converter are both taken out.

I generally recommend get a transmission built by Dana at probuilt or Clinebarger before spending the coin on a quality converter from Yank. This has been a proven combination for 20+ years.

 

Good to see Yank still in the business. I ran several of their units in my ‘99 Formula Firehawk (ST3500, SS4000, PT4400). Their PT4400 made the car an absolute monster, hit like the dickens from a dig, fantastic top end. Great folks to deal with as well!
