Does anyone know if its worth getting a new manifold when adding a blower, say a vortech SQ V2 at 10psi on a stock motor with full exhust?

if its the stock intake on there , yes. You might even pick up a little more going from an aftermarket piece to a higher flowing unit, but just my opinion, don't have enough for my blower yet

I have seen the Holley make as much as 50 RWHP more than the stock intake with a supercharger.

So yes it is worth it.

I would also reccomend a holley intake. I have one and it's the perfect size for the SQ I have on my car.

Go with a Holley or a Trick Flow. Can't go wrong with either.

EDIT: And it is EXTREMLY worthwhile to put a intake on a stock car, let alone a boosted one. The factory intake isn't worth it's weight in metal if you ask my opinion.

FMU increases the fuel pressure, but isnt very precise, which creates really rich situations. The injectors are the proper size for the pressure you want, so you dont need the FMU.

I don't know all the in and outs of an FMU.. My son runs a vortech with 42#'s and an fmu?? 525rwhp Anyway I think a custom chip and tune with 42#'s and you can get rid of the FMU. Don't know all the in and outs.
