hi -guys -im getting into circle track racing --its a 3/8 semi banked oval paved track --and i was told to run a 1600-2200 stall converter with a   350 turbo tranny to help with the rpm and to slow me down in the corners --and it would also give me more hump coming out of the corners --what do u guys think

Who suggested that? What is the normal opperating range on track thru intering the corner? Do you have the rest of the car set up for that TQ convertor? If you want engine breaking you need to run as low stall speed that you can with out sacrificing power while getting back into the throttle off the corners. If you have a higher stall speed you will need better brakes to compinsate for less engine breaking. If you can find someone to rework one for you with a high stall speed but good engine breaking that would be the best way to go. Try Mikes Transmission in SoCal.  3836bbl

grandprix25 that's probibly a good suggestion. The type of valve-body you use could make a big differance also. Talk to a good tranny guy they can tell you some tricks that will help engine breaking & still have the forward bite of the higher stall speed you will need to be a winner, the disadvantage is heat you need to keep it cool to make it last. Anything over 210-225deg. max will be quick death to the trans if ran at those temps for a any period of time the drum, clutchs & bands will glaze or seperate & fail. 3836bbl

yes i know that --i went to my engine builder --and he knows a lot of people --the tranny was rebuilt with everything new cost me about 500--hes the 1 that said i need to get a higher stall -converter and to get a bigger brake caliaper-2-3/4 piston driver side --and to use a stock 1 on the passanger side 2-1/4-piston-to help on brakeing in the corners -with the tranny- what do u guys think i need to do and he said i dont need a tranny cooler -just run racing tranny fluid--like purple royal--  not stock tranny fluid

granprix25 I figuered you were talking to someone who knows there stuff, The trans still needs to be cooled, especialy with a higher stall speed, you need to loop the circut at a minimum, just because your running Royal Purple (which is great stuff) dosen't meen you don't need a cooler. IT'S CHEAP INSURANCE, every degree over 210 is killing a little at a time. Heat is the enemy it will transfer to the engine also.   3836bbl

That will defenently pull it left I think you would be better served if you use an adjustable proportioning valve between the front & rear brakes intsed the car will want to pull badley if your braking on the straight aways the back brakes are important part of set up you can steer the rear of the car with the brakes that's where the prop. valve will help.   3836bbl

Tire stagger & air pressures will also help tremendously if the rules allow. Make the outside tires larger that will make it turn easier. 3836bbl

+1 Bud, that is fluid temp,,, the temp right at the clutches is closer to 300 and with a high stall converter and "NO" cooler,,, is plain stupid.

Yes, bigger in diameter means a lower stall which amounts to better engine braking with steep rear end gears.
