99+ autos with stalls!

Too Slow · Feb 21, 2006

i have an 02 Gt and want to get a stall for it but i have a couple questions. one guy told me that with his 3400 stall his gas mileage decreased quite a bit because of his rpm's climbing so fast. so my questions are:

1. does gas mileage decrease alot?

2. do i need a tune for the converter?

3. how is daily driving?

by the way i was just wanting to get a 3000 stall.

1. Yes, it's noticable.
2. Yes, you do.
3. Fine, and hella more fun

I have a 2800. You should start to think about a good shift kit (Jerry Mod) when/if you decide to purchase the stall. Your shifts w/o one will be different. Also, if you haven't already, look into a trans cooler.

how much would you say your mpg decrease. this is my daily driver and i cant be getting the same gas mileage as a f-350 lol. and what did your tune do for the converter? mess with the lockup points?

by the way i have a 4:10 gear, tranny cooler, and a chip for the gear and to firm the shifts already

A stall isnt going to really hurt ur mpg.. I would go with a 2400-2800 stall.. In less you are going with some heavy mods...

san~man · Feb 21, 2006

Yes, it does. Your engine is revving higher due to the stall (from a stop, for example) and therefore uses more gas.

I would say about 2-4 mpg, but then again I have a heavy foot.

2800 stall minimum.

Cantslowdown · Feb 21, 2006

true forgot the heavy right foot.. I am just glad i dont have to do alot of intown driving so.. Cant wait to get the tranny out and get the stall in and do the j-mod!

I just got mine in a week ago. Edge, 3000 stall.

1. Don't know yet. Maybe some. I'm not too worried about it.

2. Yes but mainly for shift pressures and shift points. The shifts are really jello soft now. A tune can increase the shift pressure and turn off torque modulation to bring back the kick. The stock program tends to shift too early. Sometimes it will shift but the RPMs shoot right back up after the shift so it sounds like all 8 cylinders decided to misfire in the same cycle. You're cruising along at 2800 RPM, then it skips, then you're at 2800 RPM again but in the next higher gear. Almost sounds like a CD skipping.

3. Light throttle driving feels the same way. Nothing new there. Mid throttle is where it sounds sluggish. That's when it seems to hover right around 2800-3200 RPM like you were on a boat and the shifting is sometimes so soft you barely notice you've changed gears. See response #2. Heavy throttle driving feels the same as before but it just pulls hard quicker. You don't have to wait for the RPMs to get up to 3500-4000 before the engine pulls. You're up there almost as soon as you stomp on the pedal. You can really feel the effects of the high stall when you increase throttle input rapidly. The higher the rate of change in RPM, the better the kick.

I was in a parking lot in low RPM in 3rd gear, maybe 1500, then I stomped it to 3/4 throttle and it broke traction. Because you're in the power band immediately, it feels like you have an extra 75 hp at your disposal. If it hasn't been freezing or raining here in north Texas for the past week or two, I'd have track feedback. I also got some Mickey Thompson ET Streets so I'm so itching to take the new stall converter and drag radials for a spin. I'm also switching from a Predator to an Xcal2, but the Xcal2 isn't here yet.

PS. I have 4.10s and around 230 rwhp on the dyno before the gears and stall.

What you're talking about is a high stall torque converter. I have a 4200 stall torque converter, and get 14.5 mpg on the highway and 7.5 mpg in town. Some of the poor gas mileage is due to my hp, etc., but a lot has to do with the high stall torque converter. Your gas mileage won't be as bad as mine, but it will be less than stock.

great feedback guys thanks alot

No problem man...

With a lockup converter the mileage will be exactly the same on the highway regardless of stall because the converter is locked up. So keep that in mind if you do a lot of highway driving.
With my 4000 multi plate stall converter I get an average of 28mpg on the highway. Because I can stay out of the gas and have a very efficient converter, my city mileage didn't suffer too much at all. I actually didn't even notice it really. Let it warm up outside and I will get back to you with numbers when the car comes out of hibernation. I know the highway numbers because I went to Florida with the car last and logged it.
A lot of it depends on the efficiency of the converter and that depends on who built it.
Choose wisely.
Ken, the one that owns Modular Depot, drove my car and couldn't get over the feel of this converter. He can vouch for the difference between a good one and not so good one. Most people expect a lot of slop at low RPM and it doesn't have to be that way. That slop is what kills your mileage.
I don't ever suggest less than 3000rpm regardles.

If your going to go stall look at the PI 3200 or 3500.....I run a 3200 now and driveability is great........kinda wish I had a 3500 now!

I agree completely.

Unfortunately the converter I have is now classified as Unobtanium. He is unable to make any more until some point in the fairly distant future.

awesome thanks again. i talked to a rep from P.I. and i told him that my car is my daily driver and i race it once and a while and he suggested that i get a 3000 stall. he also told me that unless i want to go with a power adder the single disc converter is fine for me.

DarrinB · Feb 23, 2006

Do yourself a favor and ask them if they will use something other than a paper clutch. Those tend to get hot and flake easily.
You know, they would make a good converter if they used a good clutch material. Other than that, they are pretty decent inside.
