Anyone have an idea how much weight it takes to effect stall? Im wondering how much my ss3600 may have changed with a 200lb weight reduction.

in what regards effect stall ?
figuring 4000 lbs for vehicle,full gas,& driver,200 lbs is only 5% reduction,I would GUESS you wouldn't feel any difference in the way the stall is acting,but because of less mass to move/accelerate,it should feel like a horsepower gain.

200lbs will not change much, if anything maybe it will lower the stall 100rpm. In general when you take weight away the stall speed will decrease, when you add weight it goes up. Hope that helps you!

Yes thanks. I knew it wouldnt deviate very much but was just curious if any builders/sponsors maybe had a rule of thumb/formula they use.
FWIW my car is 3200 with 1/4 tank gas and thinking about adding the 200lbs back. So is it accurate 3200lb car adding 200lbs would see and extra 100rpm?
I know, not a big deal...just picking brains lol

It's more of a guesstimate, but yes, you are on the right track ~50-100RPM on the flash stall is pretty close.... Doubtful that it would change the performance number at all....

Stall speed will not change with weight, only the flash and shift extension due to your mass acceleration rate.
The stall speed is a built in design of the converter.

Yea I realise my terminology was wrong my bad. Now what would be your guess on the rpm difference for flash/shift extension with 200lb difference?

Even if you feel a change in the converter, it wont negatively offset the gain you got by losing the weight. I know my car feels slower when it has added weight like a passenger or a full tank of gas. It feels like a bat out of hell on 1/8 tank and just me riding

Put your street car back together.

Oh yea no doubt. I remember before I had the stall I used to take my back seats out and believe it or not I could tell a difference just from 30lbs. The tires seemed to spin a bit more to. Sounds rediculous but when somone is used to their car they can tell small changes. A passenger is a big change especialy on braking.


Thats the way im headed. I love the weight out but even with the extra weight the car will still beat the **** out of most cars on the street around here thanks to the stall. I love seeing mercedes or bmws at the stop lights when cruising past the casinos around here.
Also it will be a plus to have a/c for next summer once again.
