Supercharger question.

[Blue_Slug]

Hello everyone, I am talking to a bud I met at a cr meet and after selling his v6 he is selling his procharger (4.0l ho p1sc kit). It comes with everything minus the tuner, injectors and fuel pump. My question is where can I get a tune for my car if I decide to buy it and can I run the SC without upgrading my fuel pump just upgrading my fuel injectors to 40lb? And if anyone has experience with rear ends (7.5) will my stock rear hold up with the added power ?

Tune you can get from Performance Dyno in NH. And your fuel pump should be fine, but upgrading never hurts. You could also buy a Kenne Bell BAP as well to help with fuel supply, but on low boost you'll be fine.

thanks for the info! Would you happen to know if the stock rear end with an open diff would be able to handle the power? I know it wouldn't put down power efficiently but I'm not planning on drag racing every day lol

Just go to Realspeed for the tune. You can work with Dan to get a baseline tune so that you can get it there safely or you can trailer it out to him since you are in Queens and he is in Bohemia. You can go with a BAP or go with a GT500 fuel pump, as for injectors you should upgrade to 39lb. injectors. You will need to get a .45 spacer because the injectors are taller than the stock V6 injectors.

Your rear end will hold up without problems. If the kit is complete and that is a big if than you should be good to go. Piecing together a kit is a HUGE pain in the ass so hopefully everything will be there despite what the seller is saying. Sometimes they miss little pieces or they get left on the car because they threw away a part that it replaced so best of luck with it.

+1 to what Sean said. Your probably closer to Realspeed. And your rear will def be fine like I said, because your not going to be running that much boost anyway. And Sean if he's going with either, I've found the BAP is a bit cheaper and obviously easier to come by, unless he happens to find someone with a GT500 selling their pump for cheap enough.

I'm in the process of finding out if everything else is there. Btw what are spacers for fuel injectors ? Never put anything in a car besides bolt ons and exhaust X_X

They are kind of like this.

FUEL RAIL SPACER KIT | Part Details for M-8510-M2L* | Ford Racing Performance Parts

IIRC the injectors on the 4.0 are a different style than on the GT & GT500 and thus shorter so a spacer is needed to bring the fuel rails to the same level as stock. I know Explorer Express includes them in their kits for the X-Charger and people use them for other kits as well. If you want you can do some searching over at mustang collective, they have TONS of threads on supercharger installs on the 4.0 as they are mainly a S197 V6 oriented site.

So this is what's missing from the kit
Missing:

- S/C Belt
- Fuel Pump
- Misc. Bolts & Washers

Are these parts easily buy able ?

Yea most of that stuff can be found cheap on eBay, craigslist, etc. But the fuel pump will be the most costly. And as stated you can try to find a GT500 pump or get a KB BAP.

I plan to stay on 6psi so I might just not upgrade my fuel pump. Do u know If I can get any bolts needed from pro charger directly? If needed
