Does anyone have a GT500 blower on their 4.6? Any feedback? Any numbers? I'll be doing it and would like to see some numbers.
The blower units will be swapped. It'll be using the TVS hardware as far as plumbing, etc.
never heard of anyone doing this...just not going to happen.
I tried doing some research into this a while back when I first got my S197, but yielded little results. If you do make it work, please let us know. I know you can pick up those stock GT500 superchargers for dirt cheap. If you can find a way to get it to fit on the 4.6L, I know I'd be interested in hearing about it!
Nasty has mentioned in other threads he is working on it right now.
You are talking about three separate things here, and it is confusing.
1) The blower itself.
2) You need an intake manifold.
3) You need all the plumbing: Heat exchanger, coolant pump, fuel rails, new injectors, new plugs, new IPTS sensor on furl rail, etc.
TVS means "Twin Vortices Series" which is the design of the lobes inside the blower. It is still a Roots type blower, but it has a little more twist to it like a screw type system has.
You need ain intake manifold that fits on a 4.6L engine (unless you drop in a 5.4 like a GT500 has in it).
The blower and the intake manifold need to be designed for one another - the intercooler must match the putput capability of the blower. A bigger, hotter blower needs a bigger intercooler.
I do not believe you can just take a GT500 blower and intake manifold and drop it onto a 4.6, but I don't know.
as for the original question, you could probably just take the roushcharger numbers (380ish RWHP) and add 30-50HP for the bigger blower (M90 to M122), my guess would be in the 410 RWHP range with the stock pully.
