Sorry about the title, folks. I haven't gotten any hits on my questions in the Oil & Lube subforum, so I thought I bring it here with a more catchy title and see if anyone of you can help me learn something.

I just found out that OilGuard has knocked up their prices substantially on their replacement filter elements. I have the EPS-20 system myself, and began to search for alternative filter element resources.

What I discovered is that OilGuard is actually supposed to be the OEM for the Racor Filter elements on Racor's bypass filtration systems. Racor's systems look virtually identical to the OilGuard systems.

So what??

The OG EPS-20 system is, like I said, virtually identical to the Racor LFS801 unit, while the EPS-60 system is apparently comparable to the Racor LFS802 unit. On the Racor site, there is a lot of data and information about their filtration systems as compared to the meager information that you find on OG's site. The point is this, that the Racor LFS801 series filtration system is reportedly rated for 150-250 Hp engines, while the next size up (EPS-60, or, LFS802) is rated for up to 400 Hp engines.

So here's my question. If I take my engine and modify it up to say the 275-350 Hp range, which is probably where I will end up, am I going to need to change out the bypass filter housing and go to the larger filter element?

To the best of my knowledge, the things I am going to be doing to get up into those higher power ranges are not going to change anything in regards to how much oil flows through the engine block or oil bypass system, which makes me wonder why a larger element might be required as suggested by the Racor site. Or is the Racor recommendation possibly based on the assumption that the 250-400 Hp engine will already be built with larger oil flow processes, and their corresponding "ratings" really don't apply to a smaller engine that is modified to higher power capabilities?

 

lol it is a catchy title


wish i could help you out...

 

Yes, size does matter..OR thats what they say..

 

I agree with you on the second part. They assume a engine producing 300-400hp should be larger than a 7.3, therefore they assume that the engine itself holds more oil in the sump, therefore circulating more oil as well. I don't see a problem with the kit you or i have now, working on a 500hp+ powerstroke engine. Like you said, it still flows the same amount of oil. Well, possibly the increase in soot blow-by could mean extra work for the filter.

 

Thanks, Kris. The more I thought about it after posting the question, it seemed that that almost HAD to be the situation. Your agreement with that makes me a lot more comfortable with the design issue.

I can't see me ever modding up to even 400 Hp, even though I know for sure that it would be a whole lot of fun to do so... the practical issues of family life just won't allow for it, and I know that I'll be happier overall by keeping "family first". You "youngun's" can go ahead and have the fun while you can.
