Olive Xm 34 Posted November 27, 2015 What's wrong with the base plates? I heard they can flex with the HP spring so I installed a second one so it was thicker. Share this post Link to post Share on other sites
Ratsun 3 Posted November 27, 2015 I'll be turning it to 7500.... Not sure I'll see 75 psi with a std pump and loose clearances?? Share this post Link to post Share on other sites
wagoon 2,429 Posted November 27, 2015 If you are looking to give it some RPM, make sure you have enough oil pressure for 10psi per 1000 rpm. That is if you want to rev to 7000, you will need 70psi and so on. So my crossy's good for 8000rpm then, time for a bigger camshaft I'll be turning it to 7500.... Not sure I'll see 75 psi with a std pump and loose clearances?? My crossflow has an Ando built factory pump with decent clearances in the engine and when we primed the oil pump it was at 80psi. Ando will remember what the clearances where on my engine no doubt Share this post Link to post Share on other sites

ando76 4,354 Posted November 27, 2015 Your all over it but even that is not enough. Their base plates aren't even faced flat Share this post Link to post Share on other sites
ando76 4,354 Posted November 27, 2015 Yes Ryan. I built abit extra into your pump because you are a blacksmith with really bid hands. So I know what you will do to that poor little x flow. It's just what I do. Share this post Link to post Share on other sites

Ratsun 3 Posted November 27, 2015 What are your thoughts on the mellings select pumps? Part number ml 10687 Failing that would you be able to hook me up with a pump to do the job? Share this post Link to post Share on other sites
Olive Xm 34 Posted November 27, 2015 Yeah I went over mine with the surface Grinder. 1 Thom reacted to this Share this post Link to post Share on other sites

wagoon 2,429 Posted November 29, 2015 So I'm about to place a order for the mellings select std vol pump.....good decision ? Going off what Ando said it should be ok, but I gather they can be improved to work better. Might be worth your while contacting Ando to see what one of his pumps are worth, then you know you will have one built to what you need. Always better to get something that suits what you need rather than a generic aftermarket item that might cover what you need 1 ricktewagon reacted to this Share this post Link to post Share on other sites
ando76 4,354 Posted November 29, 2015 Just had a look on them on the mellings site and they seem to be a good thing. I like the adjustable relief function. The literature on the site is a bit confusing as it says its std. volume and then it goes on at the bottom to contradict it a bit. I'd be making sure it is std volume pump before I placed the order. It would seem as they are and they have a few good features over a std style pump. 3 gerg, ricktewagon and wagoon reacted to this Share this post Link to post Share on other sites
Ratsun 3 Posted November 29, 2015 Ok so how do I contact u ando? I'm keen to see what you might be able to help me out with and how much I'm looking at... I want to make sure my pump is 100% what I need and you sound like the man 2 wagoon and Outback Jack reacted to this Share this post Link to post Share on other sites

ando76 4,354 Posted November 30, 2015 Yep that's about the size of Ryan's hands and arms. He is a very big boy and whilst I am not small - his size scares me so I wanted his pump to work extra well. 2 wagoon and Outback Jack reacted to this Share this post Link to post Share on other sites

Bout the only bear attack you will get from me is a bear hug when my engine fires, promise I won't break your ribs..... well maybe. How bout, I will try my best not to cause any damage when I give you a bear hug when my engine fires 3 Outback Jack, Thom and ando76 reacted to this Share this post Link to post Share on other sites

matt_lamb_160 252 Posted December 27, 2015 I am not takin sides or forcing a debate, but I think PRO250 did ask two good questions in "what is the difference in flow-rate" and "what is the difference in torque required to drive them"? That info or info similar must be out there? It is good to see people thinking about something important, that is not given enough attention. Ando built pumps may start getting real popular here.

ando76 4,354 Posted December 27, 2015 They have become very popular Matt, not just on here. It is good that people are thinking about their oiling systems. Getting it wrong has serious consequences. I don't have any tool to measure the torque difference other then my bare hands. I can run one of my pumps up on the test bench with one hand on the drill with my modified std volume pumps. No chance doing the same with a high volume pump. It really is that bad. Flow rate (free flow) has been calculated roughly with ryno's test. Of course in an engine there are a few variables such as engine bearing clearance and lifter type that dictate the amount of leakage and therefor the flow rate of the pump, not to mention the relief setting. There is a lot in it. 2 Outback Jack and gerg reacted to this Share this post Link to post Share on other sites
