stvski80085 197 #1 Posted May 13 This just looks like a neat idea. I know it's overkill but still think it's cool. Could do this on a small K series. Steve 1 Share this post Link to post Share on other sites

HyperPete 759 #3 Posted May 13 (edited) Interesting. For fun, I did a rough tally of the cost of parts for the oil cooler setup (and similar for some since they were unavailable) and the pre-tax cost is around $250. Pretty steep for a $379 predator engine!

What I really need to see is the disected spin on filter after 25 hours of running. That should be entertaining! Edited May 13 by ri702bill 2 Share this post Link to post Share on other sites
Wayne0 1,081 #5 Posted May 13 You gotta' run a small engine pretty hard to need that. Interesting concept, but a fools errand. IMO 2 Share this post Link to post Share on other sites
stvski80085 197 #6 Posted May 14 (edited) I just thought it was interesting. I will not do it unless someone gave me all the parts. I can change the oil monthly and it take years to add up to that. I only need a quart. I agree that it would be cool to check the filter and see what it actually picks up. steve Edited May 14 by stvski80085 1 Share this post Link to post Share on other sites
HyperPete 759 #7 Posted May 14 (edited) When I looked at the parts list for the guy's entire build, I kind of "understood". He's running a $500 cam, rod, & flywheel on a $379 engine. Plus other "upgrades". For a go-cart. Heck, I say throw a Hayabusa engine on the go cart and REALLY crank it up! EDIT: This one is "only" 400 HP. He has an 800 HP version, too.

RED-Z06 2,531 #8 Posted May 14 Ive run oil temp probes on older splash lubed engines back when i had a few digitron and mycron setups laying around. I think one of the hardest working engines is a power washer, they run continuously at near 100% load, i probed a few engines across a few brands and found, yeah the oil gets hot but i struggled to get it up into the normal range, it needs to regularly get over 212⁰ to cook off moisture, but needs to stay under 275⁰ to avoid thermal breakdown. Now, a filter is never a bad thing, definitely kudos for the filter, which on its own provides some oil cooling. 2 Share this post Link to post Share on other sites

If the pleats in the media are still squeaky clean after 25 hours, it was a total waste of time & money... but, if it looks like it is full of coffee grounds, well done.... 1 Share this post Link to post Share on other sites

You really never want to see anything in a filter, you'll see a few random flecks of metal, totally normal...but if you're seeing accumulated sludge and chunks of stuff you have a serious problem, like the oil is getting over 325⁰ and cooking off, or you're going hundreds of hours between changes. 1 Share this post Link to post Share on other sites
clueless 3,165 #11 Posted May 14 On those OHV engines just run full syn, they run a bit cooler and the oil change is a least doubled. I don't change the oil in my 13hp generator which runs at least 20 hours a day after one of those hurricanes but every 72 hours, and it looks like it just came out of the bottle. I haven't done it but I'm sure it could go at least 100 hours. Now it does run on propane, which will keep any engine oil much cleaner. 2 Share this post Link to post Share on other sites
