OK so I came from a vortech 4.6 2v setup to a turbo setup.

With the vortech I had a 3800~ converter and it flashed way up and went, seemed to work great.

I could put the car in 2nd gear and floor it and watch the needle jump right up to the correct flash speed around 3800 rpms before the car even moved.

Now with the turbo setup I completely switched converters to a multi disc unit that was supposed to stall around 3600-3800 as well but my issue is that it just doesnt at all.

Im not sure if its the converter, my power band, the turbo setup, or what but I just wanted some opinions on the matter.

I can foot brake it near 2k but even when I flash it, it still only goes to about 2k or so and just slowly climbs.

Here is a short video to show what it does from a dead stop when my foot goes to the floor.

Im not really sure what to think at this point...maybe its just the nature of the beast with the turbo, big cams, heavy converter?

Could it be possible that my trans filter is clogged or something?

I was told that if the fluid pressure is low the friction plates may not be backing off the converter causing friction and the slow rev up

I already upgraded the trans lines to bigger diameter and they are running straight through a huge cooler.

have you tried the 5mph, 3rd gear roll test? if you do this, should really show you what it's flashing at

Converter could stand to be loosed a touch if you're going to footbrake it.

what is the combo, engine trans, turbo size, and a/r?

4.6 2v, ported pi heads, Victor jr manifold with sheet metal elbow, HP 292 blower cams.

4r70w locking converter 67mm billet wheel comp turbo with .96 a/r

As far as the air it moves it seems to pretty much match the boost curve when spooling of a stock hci 4.6 70mm with a. 67 a/r that my tuner compared it to.

Of course loosening the converter is an option I just didn't know if something else could be the issue.

Alan @ dirty dog says this is usually as loose as he goes with this case without sacrificing efficiency

He seems to think it should be looser than is acting.

I really didn't want to send it back.

I mean it does roughly the same thing from 5. Just rpms jump a bit higher than a dead stop of course.

I can try a third gear test.

It seems like its loose when its unlocked on third gear...almost like its stalling up around 4500-5k when I do that.

That's why I'm wondering if its just cause the combo is so weak down low or maybe I have low fluid pressure?
