Who's done it and how was your experience? Did you keep your current pulley configuration and did you lose or gain any psi?
If you upgraded from any other TVS to the GEN II, how does it compare?
I currently have a FRPP TVS and have been thinking about upgrading cases and just wanted a little input before pulling the trigger.
Thanks in advance.

I've also been thinking about this lately, but haven't been able to dig much up on the outcome. I really don't think many go this route. Seems like everyone has just been upgrading to the gen2 kit and selling their old TVS.

I swapped from the VMP gen 1 case to the VMP Gen 2 case.
Using the same pulley setup I gained about 1.5-2 psi. boost.

Simple swap, took about 4 hours total.
Didn't do a before and after dyno to tell exact gains but I would guess 35-40 hp range.

I did do a pull for a dyno day at a local shop. In 86* weather 56% humidity with mods listed in sig. (minus the VMP 67mm throttle body,,Was running a FRPP 65mm throttle body)
Car pulled 684/711 with a VMP Email tune.

Car easily has 700+ in it with better weather and VMP custom tune.

I would recommend doing the swap if your looking for more power.
