External Oil Pump

I am currently running a Kaase oil pump and I am thinking about changing to an external oil pump during the winter. Anyone else running one on a A460 motor? Good or bad? Thanks

Mike Stevens and Phillip Oakley have them on their big A460 engines....works good.

Lem - do you know what set up they are running? Any pics by chance? Thanks Randy

Yes; we run one, the Moroso external pump belt driven off the crankshaft. I will NEVER go back to the stock type shaft driven pump I have a cardboard box full of the things that failed one way or another. With the Morose pump you can adjust the pressure to whatever you want it to be, we have ours set at 80 psi, We have never lost a belt or had any problems with the pump and we have been running it for about 5 years. Doing this gets rid of the inside the pan pump, the drive shaft and all the problems that go along with it. I have also canned my drop-in dizzy for the horiz. mounted belt driven dissy made by MSD, I will never use a standard type Dizzy again, I had David Willingham machine me a beautiful plug and clamp for the Stock dizzy hole in the A460 block. Last week she was clicking off 5:20/5.30 every pass with more power to spare running in a 5:30 index class, can't wait to turn the juice loose!!!!

Bobby,

Those e.t.s are good to hear. Does that mean you found the problem with that one cylinder (#3 I think).

Phillip set me up with a drysump over the winter it gets rid of that "well is the oil pressure going to come back up this time " feeling in the shutdown good solid oil system a little more costly but you have to look at your investment you have in your engine

Yes; We found the problem right after the last time you and I talked, I thought that I had told you but I guess my 63 year old memory is starting to?? We finally dropped the oil pan and knocked the # 3 piston out of the hole, as soon as I popped out I noticed that I did not see a "dot" on top of the # 2 compression ring, sure enough when Dennis assembled that piston he accidently put that # 2 compression ring on "up-side-down", we checked that side of the engine for more rings like that one but found none, I also checked the end gap on the pistons on that bank of the engine and all were filed to .030 I mean dead on .030. We put everything back together after flipping the ring and fired that baby up and have not looked back. It has already run a 5.26 on the motor with more to come we are still adjusting, and have not made a nitrous pass as yet. We are planning on running another 5:30 race this weekend and also try to qualify for Pro-Mod (fast eight) which will require the use of the Nitrous. I't going to be fun.

Mike's deal.........

Thanks

I've got a moroso pump on my A460 and it's great. Keown's engine that's in my car now has a peterson wet/vac pump on it, and it's an awesome set up . External pump is a great investment.

I've had an external pump for over 10 years now, best money I ever spent..............real nice to go out there while the engine is running and bump up the press a tad if needed..............

Mines an Aviaid, its a spur gear type pump, the bypass is also an Aviaid and is made into the oil filter housing.
