Stall choice

[Blk04MM]

Looking at a 10" 3200-3500 and the 10" 2800-3200 stall for my car. Which is a better choice? Car does have 410s

[Blk04MM]

Bump for those who were sleep and didn't see

[SC Cheesehead]

What are the plans for the car; primarily street or strip? Have you settled on the type of S/C you're going with? Do you live or drive in real hilly areas? The higher the stall, the more gas you've got to give it to get the car moving, can get old in a hurry with a high stall converter.

No SC too many miles on the motor.
Car is street only DD work, trips, grocery etc...
No hills in Florida.

3200 - 3500 stall convertor plus trans cooler. Go with a major mfg.

[ctrlraven]

If it's a DD I would suggest 2800-3000 if you have 4.10 gears. I have a 3500 and it does take a little more throttle input to get the car going under slow speeds but when the go pedal gets punched it rockets off.

If I replace my 3500 it would be with a Circle D 3000 stall.

I've driven with stalls before. I don't mind. Just wasn't sure which to get.

Why would you go 3k?

3K is a good middle of the road stall choice.

Choosing a stall comes down to where does the powerband begin, you want a stall speed to be as close to the start of the powerband for the converter to really be effective.

I went with 3500 only because I got a great deal on it so I couldn't pass it up.

Ok video told me what I knew. But what I don't know is where is that power on a marauder. Everyone says go for 3500 or have a 3500 already lol

Why trans cooler???

When I spoke to PI they said these aftermarket torque converters run COOLER and are more efficient than the factory ones.

Welp guess I don't need one.

[1 Bad Merc]

MM's already have I believe a 2600 stall in them already so going to 2800 is not going to be as big a difference. More a waste of your time.

I would look at 3000-3200 for a stall. If you do decided to s/c down the road that should also work with your power adder.

If you are definitely sure you are not going to s/c then a 3500 stall might be your ticket.

I would try to attend a MM function and try and drive someone's car that has this mod so you know what you are getting into.

The stock converter is 11", a PI converter is 9.5", with it being smaller it spins faster which creates more heat. An addition trans cooler is just extra protection as heat build up shortens the life of a transmission. The highest temp I have ever seen mine reach on a extremely hot summer day was 172-174.

I've read SC MMs run 3500 as well so I guess that's why it's ticket because its an NA and SC stall to benefit from.

I was looking at a 10" ...either way trans coolers aren't pricey so if I do get one then it'll be ok. It gets hot here in fla so that may help or may not

I was just stating what I was told by Mike at PI.

He says they will run cooler.

My trans temp is anywhere between 160 - 180.

Again I'm just repeating what was said from the company that MAKES AND SELLS the converter.

My data backs this up.

I have had a 3,500 PI Stall for $125K+ miles on an S/C. Prior to that I had a 3,00 PI for 20K miles N/A.

Some put a trans cooler that is larger than required and blocks the flow during certain speeds to the rad.

As far as driveability it's all in the tuner.

[Chi Stallion]

I plan on upgrading my tc but I'm not sure if I should go with the Circle D 3500 pro series single disc or 3500 pro series multi disc. Also kinda confused on the sizes too as they list 2 sizes which are 245mm 9" 3/4 or 258mm 10 1/4".

What's most confusing to me is this!

When I talk to dyno tuners they say the factory stall is 1,800!

People here say its a 2,400-2,600 stall!

I just want to know if I'll need one being that Florida gets hot as devils balls at times I don't know about you other fellow owners states.

Sure dont seen like a 2,400-2,600

[sailsmen]

The OEM trans cooler is more than adequate. Just change the fluid every 20K.

I have 70K miles and 70+ passes with 545RWHP in New Orleans on the same trans.

This assumes a quality tune.

Get an AeroForce Scan Gauage.

That's what I'm sayin'

[tbone]

My 2800-3200 is perfect for my setup imo, and there's no way a stock converter is 2600. The difference is dramatic. I've heard 1600 + -.

[ctrlraven]

My stock converter stalled at 1700-1800 rpms.

I may be ordering from the same company. Both stalls are the same price

Sounds bout right. Time to get mine out and get a REAL stall

[LANDY]

Get at least s 3500

[ctrlraven]

Get at least s 3500
IF you have 4.10 gears, a 3500 stall will work well when mashing the go pedal.

The 3500 stall makes an NA car with 3.55 gears even more dogish off the line under light throttle. Highway traveling is great though with 3.55 gears and 3500 stall, at least that's what I noticed since I had this combo for about 3-4 years before having my 4.10s installed.

This is true......

[whitey]

Where is the powerband in our cars? ~3000 start?

At least? Lol how much higher can one NA owner go?

You're 4.10/3500 right?

Good question... Someone answer that for both our info

[LANDY]

I have a 3800. As long as you can deal with giving slight more throttle while city driving a 4k would still be fine and put you in the powerband quicker.

[ctrlraven]

Yes I have 4.10s and 3500 setup now on the stock motor.

After installing the 3500 stall my shifts become very soft as the converter "absorbs" that firmness in a way to say. Did the JMOD, upgraded the EPC and TCC solenoids and replaced the pressure regulator with annular grooved one from Sonnax. With doing all these I had to back my shift pressure down to between 0 and 5% because at 15% for the 1-2 shift @ half throttle it was barking the tires and 1-2 shift at WOT was spinning the tires while jumping about 10 mph. lol

Sounds fun ....might give it. Go

Lol I'm with you on that. GO GO GO

4k ?! Good lord. Zero traction

[ctrlraven]

High mileage on the transmission and not trying to break something.

PLUS the fact that several times I had made a turn the car shifted during the turn and the azz would jump over or on a wet road I would spin out.

That's 355 or 410

[ctrlraven]

That's 355 or 410
That's with 4.10s.

4.10s and 3500 stall with slight trans parameter adjustments (if needed) are a good NA combo if you like to run at the track or get up on it from a stop.

Noooope no track. Sounded like your car hooked with no problem with 4.10s and 3500

[tbone]

That's correct. That's why I believe the 2800-3200 is the best choice and was the most highly recommended by several trans builders I spoke with.
It feels great in my car.

[99SVT]

Peak torque N/A is around 4200, so try not to go over that. For all out performance I'd go 3500-4000. If you want more drivability, go to the 3000-3500 range. 3500 seems to be a good sweet spot, especially if you have 4.10's already.

4k stall sounds like its all fun. Lol

I think I'll stay with the 3500 ...still would like to get some type of mileage on the highway for road trips. My 4.10s and 3500 should be fine/fun for my car. Get it up and moving when it needs to.

[LANDY]

A 4k wont affect your MPG on the highway since the converter will be locked. It will big time driving in the city. I get 14mpg driving conservative in the city. 20 on the hwy

So 4.10s, 4k stall, headers, intake, UDPs would make for a nice NA MM

The Marauder has a 36-3800 triple from Lonnie of BOC , with 418RWHP it is perfect!
The GMQ got the stock convertor restalled to 2800 and a jmod with 4:10's
