Hey what's up guys.
I need alittle advice here. I just purchased a Powerdyne 6 psi supercharger for my 1991 f-250. The complete kit did NOT come with a blow off valve, in-line fuel pump, or any timing adjustment device. Powerdyne states it is not needed for this kit. Any reason why? And should I buy them for my setup? I have no mods to my fuel system, other than 24# injectors and a Mallory adj.fuel pressure reg. I have dual gas tanks w/ the original fuel pumps.
Here is my setup:
rebuilt 5.0L .030 over
Edelbrock performer heads,mild port work
Edelbrock performer truck intake/plenum
Bbk 61mm T/B
Ford racing mass-air conversion kit
Pro-m 75mm Mass air meter
FMS 24# injectors
Ford A-312 cam
Heddman Elite long tube headers w/ custom dual exhaust

Any advise would be appreciated.
Thanks,
Jerry D.

 

The blow-off valve won't be required - they are for turbo's to stop them spinning backwards.
An inline fuel pump would be nice, but not necessary.

I don't know about the timing adjustment - it depends on the engine - but it seems reasonable that it wouldn't be required.

 

So I should be OK with the setup I have now to install the kit.

 

What you're talking about is a bypass valve, and at 6psi, you shouldn't need one. I'm not so sure that you will see 6 psi given your build, being that you have better flowing parts than stock...a smaller blower pulley will remedy that though.

I would suggest getting an inline pump though. Your combo will be making more power than stock so you'll need more fuel to support that. And a boost timing retard would be wise to keep it from detonating, unless you plan to go with some type of aftermarket tuning.
