I have the mods in the sig and currently I am running a Vigi 2800. I am ready to step it up a notch and get some better 60' times. My best 60' to date is a 1.57. I was thinking about going to a 3800 but have read about LT1's not liking that high of stall. What would yall suggest that I go with to get them 60's down into the mid 1.4's ??

Spray a little more N2o out of the hole I like tight converters and boost+gas or either. But I would not think you would need a 4000 conv. The most I would go is like 3500 but thats me. Later Clint

 

I wouldn't think you'd need anything really loose, I'd stay in the 3,200-3,500 range. I've also heard that the LT1's don't like really high stalls, but I know several people running 3,500 stalls or under, and none of them have problems. Good luck!

 

So yall think that say a 35-3600 would be plenty to get the car to cut some 1.4 60's???

With the proper amount of Torque, easily

 

Depends on the torque multiplier of the converter. 2 different 2800 stall converters can act completely different.

Find out what the torque multiplier is of the vigilate converter first before swapping converters. Also, what's the diameter of the 2800? A 12" 2800 will act differently than a 10" 2800.

The stall speed rating is only an estimate of the converters stall. The stall speed depends on how much torque is put into the converter. Using a transbrake is the only way to know the true stall speed. A converter that stalls at 2800 in your car may only stall at 2500 in someone elses so don't always accept what works well in someone elses car will work good in yours. It may work better but it also may be worse.

Some 4.56 gears would get your 60' down some more as long as you can get traction.

 

Certain LT1's don't like high stalls...just the OBD1 LT1's don't like them...OBD2's are fine....I would go with a 3200-3500 stall, 2.5 str too.
