Just ordered Holley intank any opinions on this pump? I'll be running fmu 10:1 w/ 5-6 lbs. boost.

 

You're gonna be looking at a total of 90-100psi at the rail with a 10:1 FMU at 5-6psi, which is pushing the limits of an intank pump.

 

I think that may be conservative. Most fuel pumps cannot flow well enough at that high of pressure to support the boost that is being created. I would consider running a lower rate FMU or getting a standalone.

 

would it help to add say RC 310"s.This would reduce fuel pressure at the rail right. Since they are larger inj.

 

yes, bigger injectors, with a smaller FMU will work.

 

What rate of Fmu should I use any suggestions? Maybe 8:1,6:1 or whatever.

 

What size injectors and how much boost?

 

Once again this would be on a stock 1.6sohc 5-6psi w/ factory inj. or possibly 310's.

 

8:1 sounds good on 310's, but at 80-90+psi of fuel, you'll definatley feel safer with a high pressure pump.

this pump does it have to be inline or will intank work.

 

High pressure inline.

 

Holley pumps are just rebadged and repriced Walboros, fyi.

I bought a high-pressure intank for about $160-170, it was the wrong model so I took it back. I got the DSM pump which fits the preludes better, and it only ran me $130 shipped from someone online.
