What was the fuel PSI and the BSFC #s of the engine?

The pressure was set at 60 lbs. No BSFC numbers, we ran a -10 feed and -8 return line directly to fuel cell because my dyno only has fuel metering on the inlet side.

60PSI at idle or with boost? If at idle, what was the fuel pressure under boost?

60 PSI set at idle with return fuel regulator vacuum line off. The build was done by a member of OSO that does not frequent the site, if you would like to go over the build with him I can contact him with your info.

OK, well my point is that the A1000 only moves 702lbs per hour of fuel at 60 PSI. So lets use round numbers and say that you were using 10PSI of positive manifold pressure to make the 1100/1100 numbers you posted. If the FPR is referencing manifold vac/boost then they fuel pressure is now 70PSI, and the A1000 can only supply 670 lbs per hour of fuel. Most Whipple motors will run with BSFC numbers in the .650s to the .720s. So using the lean and mean assumption you require 715lbs per hour of output from the fuel pump.

Are you sure the Eliminator pump isn't what was on those motors? They can (barely) support those power numbers, but the A1000 has a very high probability of failure in the aforementioned application.

Not trying to be a smart ass, just illustrating my point of why I have seen these pumps fail above 750HP in EFI forced induction applications.

It would have to be the Eliminator pump. Not trying to argue or get in a pissing match, but I've seen an A1000 not be able to maintain 60 psi through a dyno pull on engines around 900 hp. You can go back and look at the printout and see the pressure steadily falling throughout the entire pull, instead of increasing like it should. The Eliminator pump has a -12 inlet and -10 outlet while the A1000 has a -10 on both ends.

I'm not saying that there is anything wrong with Aeromotive's pumps. Just get the right size pump for the job. I've used them all and prefer a Weldon. Their 1100A is cheaper than the Eliminator, quieter, and supports more power.

Percision, I tried to PM you but box is full.

any update on the 5.3?

My wife and I fell in love with a house a few days after I posted this. We ended up moving and the boat project was put on hold. Thankfully I have a nice pole barn to work on the boat now. I can also be on Lake Michigan within 10 minutes of leaving my driveway now. :)

I bought a lot of the Holley parts I needed during their Christmas sale.

This weekend is supposed to be warm...and the wife is gone. I plan on designing the engine mounts and getting them mocked up on the 3D printer at work. I'll start a build thread to start chronicling the build.

This Bosch pump 0 580 254 979
Is capable of 525 hp at 42 psi and is factory fit by Mercruiser.
I have one in my Donzi.
