Default PT4000 and turbo

I put a new trans in my car a month back and am in the process of heads and intake. The trans is stage3/4, but I used one of my Yank converters...PT4000. I did not think about it until now. I had a friend that was going to buy the trans and converter so I could go glide or t400, but not sure when he will be able to. so I put everything together for now and was going to drive it for a little bit, but now it does not sound like a good idea since I will not be able to keep my foot out of it. 9" 3.55 in rear, 370, 12psi, t76, ls3 heads, vic jr intake. What should I expect if I run this converter? The cam is good to about 7100 as is the bottom end.

+1. If it's an off the shelf pt4000, it'll probably be stalling around 6K rpm once you're in boost and shift extensions will be small to nil.

Thanks... that is what I thought. I have a nice 3600 vig ready for combat. I will pull that one off of the shelf and put it in. Thanks for the help.

The usual choice in yank line is the PY extreme series for turbos. Not too loose around town but can still work good with the boost. I run PY3400e in my build. To other guys running these are Mightymouse and Cablebandit and there cars both seem to run really good with them.

Only think not crazy about is Yank said not to lock it up under high power like mine. So triple disc vig that you can lock up maybe at high power might be a bit better in terms of ultimate efficiency for heavy track use. But think the Yanks are still pretty high efficiency. I dont' track my car enough to really care.
