I will be receiving a 5 psi ford racing blower from a friend and would like to make sure I get enough fuel.

I do not want to run an in line fuel pump because I have no desire to go over 5 psi or 500 hp. And I just dont want 2 fuel pumps.

So can I just get a 255 lph BBK or trickflow pump or somthing that will go in the stock location?

Thanks, clint

with 5 psi, you wont see 500hp, and im not even sure you need a new pump either

someone more qualified will chime in soon.

You might get away with not needing a fuel pump at all, but to be on the safe side, I would at least throw an SVT Focus pump in there. That's what I'm running on my setup at 10 psi, and it seems adequate. I don't know how much headroom it gives me, but I know it can flow enough fuel for about 400-450 rwhp.

he has a 96, run a single 255 walbro pump and you'll be fine.
and at 5 psi you'll be lucky to break 300 hp!

what kind of blower is it?

You'd probably even get away with a 190lph to be quite honest. I'd go with the 255lph unit anyway....god knows when the horsepower bug hits and 5psi of boost won't wet your whistle anymore.

will 5 psi even make up for the power it takes to spin the blower?

The blower I'm getting is the old ford racing blower. I have seen threads a while back on this. I'm getting it from a friend for a pair of GT-40 heads. Pretty good trade if you ask me. Do yall suggest I get it rebuilt before I install it. Also what MAF sensor should I get and what size injectors. The MAF must be compatible with the SCT XCAL tuner. Remember 5 psi is all I will be going with untill I get a new short block and meth cooler or intercooler of some sort.
Oh and the reason Im getting a fuel pump is because my old one took a crap on me and went south.

So I ended up going with the Holley 12-915 which is the last fuel pump I woud ever need it will support up to 700 HP which I will most likley never see. And is probably an over kill being a 255 High pressure. But it's better IMO to have too much than too little.

Thanks for the imput guys I appreciate it and keep coming with the resposes, I like the feed back.:SNSign:

you can run 10 psi for YEARS on a stock bottom end. 10 psi will make around 375 to the wheels

a lightning MAF and 42# injectors will cover what you need. both can be had for under $300 on buyfordracing.com

Well at my last dyno session we came up with 254.5 Hp @5300 and 299 torque @ 4400 so I hope I would be able to break 300 hp with a blower even a just 5 psi.
I will also be porting my Pi heads and getting some blower cams.

I also have a mostly aluminum drive line like flywheel and drive shaft. So the car is pretty efficient at getting power to the wheels.

OH the blower is the old ford racing blower. I might go 7 psi but no higher. I just want a street car that can pull up to the drag strip from road as is and run low 13's or high 12's on my regular Firehawk tires. And ride home with the top down with my Girl.

I still have my drag car If I wanna go real fast.

So you already have PI heads on the car, I take it. Be careful with boost and the raised compression of the PI heads. 5psi and a good tune should be fine, with your PI heads, you should see over 300rwhp. How are you mounting this setup on the PI heads?

Acually I dont have the Pi heads just a good port and valve job on the NPI's I do have some concern that when I do get the PI's I will have too much compression. Thats why I only want 5 psi.

what cams are you running? If you are putting down 255rwhp with stock or PI cams, and NPI heads, I wouldn't run the risk of adding PI heads with that blower. With 5psi, I would guess you will be in the 320-340rwhp area. You can always add more boost.

My brother had a the SVO/FRPP blower on his car, which I drove a bit about 10 years ago, loved it with stock NPI heads, then SVO heads . I'm sure others will chime in, but I would leave the ported NPI's and up the boost slightly if you want more power, rather than go with PI's with the raised compression. Get a good tune on the car. Plus, it will save you money on heads.

What power do you want? The FRPP blower is going to max itself out way short of what a twin screw or centri blower will.
