mechanical fuel pump limitations

[jimbob-mcgrew]

i know this has been asked before, but i cant find it in the search menu, so asking.

does anyone know what kind of horse power the smallblock mechanical fuel pump is limited to ?

seeing as its only any good for carbs anyway unless your building some t40 super high revving beast it should suffice to pretty much all aplications

only 8000 rpm :)

Im in the process of building a C16SE on twin 40s and will be using a facet pump because my last nova that had 40s on was my daily car for pleasure and work (yes cost me a fortune to run).In 6 months i went through 2 mechanical pumps,they just stoped working and i could only put this down to them not been up to the job,like i said it was my every day car and did high miles.

Mechanical is fine on my Sport (got a pressure regulator) inline

I kept the mechanical pump on my old Sr 1.4 bike carb setup with a few engine mods which was pushing 130bhp.

I think Ben (boffer8) is still on a mech pump on his bonkers 1400 8v loon. So you should be fine. That said, i'm going for a dual facet setup on mine for reliability and redundancy

Jim's 1650 8V with BP300 cam ran a standard (NEW) mech pump and he made circa 150bhp and ran to about 7.5k iirc
