What fuel pump will I need will be building a 351W probably turbo looking to make between 500-600hp read all the info I can find but I am not very good at  math. I know an aero. A1000 will work but lookng for something not so expensive I know you get what you pay for but I think from what I have read that you can use a smaller setup.

You know Greg that's a hard one to answer as it really depends on your BSFC.  I would have no idea for that combo but my simulator says 32 GPH for a 390 HP 306.  I would say you need to double that and add 50% then look at what the pump flows at pressure.  Most of the ratings I see are at peak flow which means no backpressure which will be higher than at 6 PSI  I think this is why guys use 70 or 90 GPH pumps on 350 HP engines.

BSFC is higher on a forced induction setup than a naturally aspirated one a a rule of thumb.  Higher fuel line pressure also causes a pump to work harder and not deliver as much fuel.  A fuel pump delivers volume, not pressure.

Get a A1000 with a boost referance regulator, you do not want to go lean at 25psi boost and 7000rpm. Your cheapness will get you a broke engine.

Listen to these guys they are all correct....... Or you can also go with a Magna Fuel Pump. I baught the 900 series for my turbo blow thru set up..... worked great......  You really need to spend the money to get a good fuel system when going turbo...... they really suck the fuel. (Old saying better safe than sorry)
