The cam I installed last year suggested I have a 3200 stall converter. I have a 2500 stall now. Any issues you guys have running a higher stall on the street? Like heat? mileage ? Anybody kicking themselves for going with a higher stall and wishing they had stayed lower? I'm sitting on the fence here with my options.

 

If you are considering a 3200 stall converter, mileage should not be an issue.....yes it causes more heat and less mpg, but it is purely a performance item....similar to a rear gear change. The penalty for higher performance.

The difference can be quite noticeable between a 2500 stall and a 3200 stall on the street. Are you satisfied with the 2500 you have now? Does your cam really need more rpm out of the hole? Without knowing your engine's torque curve, it's impossible to recommend a converter. But if you are relatively sure you could use more stall, your "street/strip" car will definitely be more "strip".

I have a custom 2900 stall converter (flash stall to 4300 rpm) and I like it much better than my previous 2500 converter. No regrets, no problems, very efficient on the street. But again, mileage mpg is not a concern. And with any higher than stock stall converter, a transmission cooler should be added.

 

Perfect response right here.

My new street/strip build is using an 8" 4400 stall converter-MAJOR heat issues Lol so far but just put in a new cooler with a fan-be back testing again hopefully this week to see if she doesnt cook the trans fluid again.

 

Thanks for the responses. I got it in yesterday. You wouldn't know it has a 3000 stall in it until you step hard on the go pedal. Then it turns into an absoulte beast !

Always has to be something though to extend the build. I had welded a plug and sensor into the oil pan so I could add my oil gauge. I broke off the brass end of the sensor AND while 'testing' out the converter I zipped up the tach to 5500 rpm. Probably the 1st time its been there EVER. Power steering pump didn't like it and either piled up or I stirred up something and plugged it (hopefully). I'll check the pressure relief valve tomorrow. Anyway its armstrong steering right now.

 

Your power steering pump should be able to take 5,500 rpm repeatedly without a problem.

 

You've got a cam that recommends a 3200 rpm converter in an engine that never sees 5500 rpm? Something sounds odd about that. Have you actually looked under the hood? Maybe the power steering just threw the belt off.

[size=16px]I bought a 2017 Grand Sport two years ago from an idiot that just slapped a Lt4 supercharger on it, Lt4 fuel injectors, and a weapon x pulley. Long story short, I had to pull the engine to make sure there was nothing wrong with it, but the rings were shot. I put forged internals in it, stage one cam, Weapon X pulley, cold air intake, long tube headers, high flow cats, xpipe, AFM delete kit and of course a ECM tune. It's been driving badly. It just doesn't seem like it has the power and shifts terribly. It started shaking really bad during acceleration, and we thought it was the drive shaft rubber couplings. It's being pulled apart as we speak and having a custom-made carbon fiber driveshaft made with the rubber coupling delete installed and TCM tune. After being pulled apart, we realized it was a bad torque converter, so I will be adding a Circle D or Yank torque converter installed with a 3000 stall. My Speed Shop wanted to find a 2800 stall, but only the 3000's is readily available. I'm assuming I won't notice the difference. This is only a weekend driver, and I love to drive it like it's meant to be, but I don't want it to be completely annoying when just cruising either. The car was extremely fast, but the transmission was clunky and super slow. I had a ton of shutter, and it destroyed my torque converter. I'm wondering if this could be avoided with a TCM tune to begin with, but I'm excited to see what the upgrades will bring. My car has about 650 wheel hp, so the upper 700s at the fly. Any suggestions on which brand to use and which stall speed?[/size]

There are more varibles other than just the cam that determines stall
