Anyone running the dept. of boost GT450 manifold that allows a gt500 blower to mount on the 4.6?

 

What do you want to know? Lots of guys at the Allfordmustang board running them. They have only been around for about 6 months.

 

Are they good? How's the install?

 

The outcome is excellent like a factory 450rwhp. About as hard as doing a intake manifold. You save money by buying a used low mileage SC and assembling your own parts list. No fabrication required unless you count splicing a wire and cutting a hose.

 

I'm in the process of putting this kit together as we speak and I'm estimating a little north of $3500 for all the parts. Keep in mind that I have not been patient with purchasing a lot of the parts and have chosen to buy new on some stuff. Also, keep in mind that the word is getting out on this kit, so there aren't a lot of people willing to get rid of their GT500 superchargers for $200 or $300 anymore. I'm sure it can be done, but you're realistically looking at closer to $3800 to $4000 for the components now. It's still a couple thousand dollars cheaper than even the cheapest PD blower out there, so I still think it's a good idea. I, however, don't want to wait for that perfect deal to come along, so I'm ending up paying higher prices for some of the stuff.

I guess what I'm trying to say is don't pay attention to what others are paying or have gotten their components for. Somebody's always going to get a better deal than you. If you can find the parts used, it's a good thing. If you can't, no big deal. Boost still costs money and you're going to have to spend some with this kit as well.

However, I have ridden in a car that has the setup and it was a blast. It took me actually riding in a car to convince me to do it, but needless to say, the night I rode in the car, I bought a supercharger and started putting the pieces together.

 

I have a stock GT500 supercharger and plenum that I just pulled off of my car.

Works perfectly
