No, you dont.

nope, you don't need a high volume pump. and that's true about the 10 psi/1000 revs too. some people insist on having like 40 psi at idle, but there's no need for it.

That said, is a high-volume oil pump worth the money, or does it really not provide that much more protection?

Nope you don't need one if your bearing clearances are tight or to stock specs and your not pushing 7500-8000 rpms. The best thing I did was swap mine out this winter, car runs much better and no breathing/draining problems like I had.

A high volume pump will not help your small ford. It causes extreme windage, leaks oil out of every crack after a full throttle pass, and will pop out your oil gallery plugs if they aren't tapped. Use a stock replacement pump with a heavy duty oil pump driveshaft. High volumes are for race engines only.

Well,
Let me be one of the very few....errrr (looks like maybe the only one SO FAR)...to say a few nice things about High Volume Pumps. I happen to run a Milodon HV Oil Pump and it is awesome! True I shift between 7500 and 8000 Rpms, so that is important to factor in. My oil Pressure is allot more responsive then when I had my stock pump. I would think the other benefit of a High Volume Pump is that it gets the oil to your parts allot quicker. As for oil leaks, I have none (watch, now that I made that statement I will be stuffing rags into every corner of the block http://www.mustangworks.com/msgboard/smile.gif ) Seriously, no leaks to speak of at this time. In any case, some other reasons to get a HI Volume pump for allot of you mustang owners, In paticular you SuperCharger and Turbo guys is that you should see a 20% to 30% increase in performance both in volume and pressure. Why is that important? Well the greater the load on bearings, like increased compression will do that. And we all know that many a mustang owner runs SuperChargers and Turbos on their cars and both applications raise your compression ratio significantly which in turn places allot more stress and load on your bearings. Anyway, just my two cents. -James |
well i am planning on doing a TT early next year but i will swap it back in then i guess..thnaks for the help and i will be swapping a stock one back in...a motorsport one or soemthing off the shelf from autozone??
