I have a 94 Z28 A4 with a computer tune and CAI with the 3:23 gear and have run a best of 8.95 with a 2.01 60' in the 1/8th and I am having my trans rebuilt and putting a 3000 stall in it. Hopefully I will have it back this coming up weekend and was just wondering if its going to lower my ET or will I be dissapointed. I am also installing 1.6 roller rockers and have a set of drag radials ready too.

thanks

 

A good stall will lower your et. What kind did you get?

 

Its a TCI street fighter. The salesman told me it will stall around 3000 but dont know about that.

thanks

That should work out good for you. I have a friend that just got a Tci 3000. It worked out really well for him. I don't remember his times but they were alot better then the stock converter. Good luck. Don't forget to get a cooler.

 

I believe TCI offers one free adjustment if it stalls too high. Definitely install a cooler and a manual lockup switch for the highway.

 

ok a few more question how will I know if it stalls to high and what kind and where to get a trans cooler.

thanks

A trans cooler can be found all over. Summit has a few choices, most f body performance shops(ls1speed,thunder racing,texas speed&performance) will all have one for our cars. They range in price.
The stall and sticky tires should really help, with them you should be able to cut 1.8 60ft. That alone will drop .4 off the timeslip. As for the rockers they should be good for a 1 mph and a tenth. Overall you should be very pleased if you can cut good 60ft times. good luck

 

The goal is to stay in the powerband. I have a 3600 stall and shift 1-2 at 6000 and 2-3 at 6400 for maximum performance. However everything about my motor is not stock.

In a mostly stock vehicle your shift points will be lower, I am guessing around 5700 for the 1-2 and 5800 for the 2-3 shifts. You want to be careful not to hurt anything because it is your daily driver. basically the stall speed represnts a theoretical lockup number for the torque converter. Depending on many variables a 3000 stall converter will lock up somewhere between 2700 and 3300, depending on many factors. If it locks too high you won't have much time in your power band before it shifts again. Each car is a little different. You just need to try it and see what happens.

You may want some drag radials to help with hooking up because your car will be capable of posting a better sixty foot time with a higher stall, which means you will have more traction issues than you did with the stock converter.
