Semi slicks without dry sump?
Discussion
Doesn't sound a good idea to me. If you're aiming to make increase your corner speeds by fitting these, which has to be the presumption, you will be running a risk with a wet sump. Not one I'd take.
If you're implying that these budget tyres maybe aren't that good so may not create the risk, why bother? If you get increased grip, there's a risk without a dry sump.

I don't think you necessarily need a dry sump, but agree you'd want an Apollo.
I ran Toyo R888s/Yoko A048s (so road-legal track tyres) on both my Caterhams (used mostly on track - about 10 trackdays all told) and both were wet sump with Apollos, both K-series. I noticed some oil pressure variation, but nothing too concerning. Wouldn't have risked it without the Apollo though.

Speak to Think Automotive, preferably by phone as they're a bit old school, they do a kit for k series cars that has everything you need. I ran one with a DS system and it worked perfectly.
As an aside I got the DS system because of the mechanical OPG...I had an apollo tank first and even then I didn't like what the MOPG was telling me in right hand turns using CR500s on track. YMMV of course, but at the very least get the Apollo and the mech guage and see how you get on.

Dave Andrews of DVA recently explained on BLATCHAT in a post entitled Apollo Tank? dated 20/06/2016:As an aside I got the DS system because of the mechanical OPG...I had an apollo tank first and even then I didn't like what the MOPG was telling me in right hand turns using CR500s on track.

The pressure may drop, but the bearings are still receiving oil rather than air, this makes a big difference.
In my experience most engines that have Apollo tanks have bearings that are in good order, most engines that don' t have bearings which are damaged.
Oily
My interpretation of that was that whilst the pressure drop will be recorded on the gauge that is a reading where the sender is located. The Apollo tank reservoir is designed to provide lubrication to the bearings in this type of scenario.
