Procharger F-1A - 2003-04 Mach 1 Registry Owners Club

SergeantZ · 03-14-2017, 11:53 PM

Hey guys, I have an '03 Cobra with a 5.3 big bore Boss block motor and Mach 1 timing cover. I have decided to do an F-1A kit and since I had a Mach 1 cover I'm going with that setup over the '03 Cobra. I had a few questions from you guys that have done this before:

-8-rib pulley setup, where can I get the pulleys needed for this?
-Which water pump works with the 8-rib pulleys?

You can piece the 8 rib set up together. The pullies are actually from the trucks. I ordered mine from Tasca. I used a variety of washers to line everything up.

You need the longer water pump to run the 8 rib set up.

I might have an 8 rib crank pulley from an old set up.

I wouldnt bother with the GI Joe kit, didnt work worth a **** on mine. Buy the truck pulleys as mentioned and play with shimming it yourself.

Awesome, thanks for the info. Which truck do you guys use for pulleys, 2003'ish F150 5.4?

Can anyone tell me the pulley combos for an F1A to reach 25+ psi? What size/brand crank pulley? Blower pulley?

Also, the tensioner listed above is a 3-bolt design, mine needs a single bolt. Any recommendations?

01yellerCobra · 03-18-2017, 02:30 AM

I ran a Thump tensioner. I had the old one that needed to be reclocked. But once I did that it worked awesome.

For pullies I ran an ATI 12% lower (I think) and a 3.9" blower pulley. That got me 19psi on a 5.3 with full exhaust and ported intake.

whats the going price for a used F1-A these days...

Great, thanks for the info, I'll be on the lookout for one of those.
