converter experts come inside

trying to figure out what i need....

stock cube 231
champion ported stock irons
champion ported stock intake with accufab plenum and 70mm tb
gt6776 bb turbo
3.42 gear
car weighs around 3400(no weight reduction)
jimmys built 200-4r with brake
i run 27" tall slicks at the track, and 255/50/16 mt radials around the street
engine makes just under 600hp to the tires pulling it to 6400 rpm on 26psi of boost.

if im forgetting something you need to know, let me know.

i have a older vigilante 3400 non lockup. i think its hurt, the car hangs at about 5600 untill the tire speed catches up and then will continue to rev....

thanks. jeff.

What cam are you using?
With the 67DBB are would look in the 2800-3000 range, a little more with a cam over 210. Over 210, 3000-3200. The 67 does not require much to get it lit off. "Maybe" with a 85 ex housing another 200 or so stall. But, the tune can help off set this.

This is a mid 9 sec grind.

If you were to get one from me I'd want the 9.5 non lock in it. The combo has a lot of potential.

As for your issue with the rpm. That's normal and the converter is most likely fine although it could be on the loose side depending on what you do with the combo. If you shifted the car at 6000 it would barely couple at all. I bet it drops back to 5600 on the gear change. This rpm is your flash stall. So in reality if your going to shift at 6400 the converter may work pretty well.

The only way to keep it from laying on the converter like that is to apply more power to it. If your slip goes up, the converter is too loose.
