FEnatic Posted September 7, 2005 Share Posted September 7, 2005 OK, I tried the search for awhile and found some interesting stuff, but, to use a mechanical fuel pump in a boost situation you need to raise the pressure. Is this a matter of using a high pressure mechanical pump with a boost sensing, rising rate regulator, or I've heard that a mechanical pump can be modified to increase pressure depending on boost? Where can I find out about this, I've googled for awhile too but not many definite answwers. I want to twin turbo a V8 Ford I've got, but keep the carbs on. I know about the carb mods too. Any help here is appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
2126 Posted September 7, 2005 Share Posted September 7, 2005 Have you considered discussing this issue with the turbo manufactures and or fuel pump and regulator manufactures? Quote Link to comment Share on other sites More sharing options...
FEnatic Posted September 8, 2005 Author Share Posted September 8, 2005 most of what I've seen is modifying an aftermarket high flow pump, supposedly it's super cheap to do. Just can't find anywhere on HOW to do it. Quote Link to comment Share on other sites More sharing options...
Guest jds6175 Posted March 4, 2007 Share Posted March 4, 2007 Check out this website racepumps.com, they have a mechanical pump that will flow some numbers for about$ 399. You can also run an aeromotive A1000 pump which I think can handle around a 1000 hp. I plan on running the aeromotive with a boost sensetive regulator on my 351w, carb'd , with a supercharger. The aeromotive is an electric pump that requires you to run a return line to the tank off the regulator whereas the one from race pumps doesn't require it and can handle up to 2000 hp i beleive. The good thing about the mechanical pump is the rebuild kit for it is only $10! Hard to beleive! Good luck! By the way, where did you find out about the carb mods? If you can, would you mind sending me the link? My email address is flyboy262626@yahoo.com . Thanks! Quote Link to comment Share on other sites More sharing options...
getZ Posted March 4, 2007 Share Posted March 4, 2007 You can also get info on this from the centrifical supercharger guys who boost with carbs as well. Same set of problems, sealing the carburetor, fuel pressure readings, etc. Quote Link to comment Share on other sites More sharing options...
Tony D Posted March 5, 2007 Share Posted March 5, 2007 Ohhhhh, young-uns here, eh? LOL To get the rising fuel pressure from a mechanical pump, you tap the 'spring side' of the diaphragm housing, and supply boost pressure. Your resultant fuel pressure will rise as boost does, and keep original fuel pressure biased by the original fuel pump pressure plus boost.
