Sounds like you may have an "odd" one... The one we have on my friends Mustang is actually just as quiet as the factory in-tank pump and quieter than the Borg-Warner replacement pump in my 97 Suburban.It's not very quiet in my car compared to the A1000's. I am going to try and use some isolators and see if that improves the noise.
No, but anecdotal evidence shows it actually supports more like 1100hp, or about the same as a pair of 255's.A pair of 255s will support 1800hp with EFI? Even if they did, by the time you bought 255s, fittings, and y-blocks you would be in it for more than the price of the Holley. I think that the noise has a lot to do with base pressure. A carb set up with 7psi will be a lot quieter than EFI at over 40psi.
Tight spot right now.. It works.. I was gonna do cable drive.. But read a lot of broken cables and finding a grant mccrary is hard to search forI don't understand? The obvious main benefit to these is cost. If you already have the superior (and more expensive) setup, why take it off just to have electric pumps?
I've absolutely ran 159 multiple times at 3550# call it whatever hp you'd like. I don't think you are going to buy one from a retailer for $257 today. but still much less expensive than Magnafuel. I would no take a belt or cable drive off. I would consider supplementing a belt drive with electric and remove the belt for long drives.It is strange that Fastcat says 1100 on gas and TurboBu says 1050-1100 on E85? The 12-1400 should make 1100 on gas.
