7163 turbo and auto trans ?
 
Anyone ever run this turbo on a auto at the drag strip ?

I had zzp installed and tuned my 6758 on my ss auto. Even with that turbo I am only tuned to 23psi. With running more boosts I will be risking destroying my tyranny. At least that what zzp tuner told me.

After just a quick search it appears there is some fabrication involved and then tuning, and that many mm larger, might cause a lot more spool up time
I would consider the K04 if your SS is a DD.

I already have the 7163 in.. was just curious if anyone took it to the track being in a auto is all.

Ah, I see, well it’s test and tune time then, I don’t recall anyone with that setup.

Ahh I just like to cruise .. drag strip is rough on the drivetrain lol .. was curious is all how well the trans handled a full 1/4mile run with that turbo

Unfortunately we don't have a lot of options with auto transmission. Reducing shift time with tune and installing extra trans cooler, that about all I can think of. How much are you making with that turbo on 25 psi?!! Shold be around 380-400 whp

Yea not much you can do. Tune it .. trans cooler .. good fresh fluid . And I don't know never dynod it. Yet ! But I have more mods also cams and all bolt ons also.
