Comp Cams DLC Hydraulic Flat Tappet Lifter

[ProfessorRock]

So ,my kid tells me not to start any **** on this forum but I just can't resist this one since I am just a dumb former metallurgical researcher who developed metals for the space program so having said that I'm thinking maybe they should offer one free grade point with each set of lifters and a free subscription to MAD magazine and not even consider that the machines that it takes to apply DLC to a piece of metal cost about $250,000 each. It uses a process called PVD or plasma vapor deposition and just a little bit of technical knowledge to run the dang thing so this just seems like somebody's worried about competition in the marketplace, too late welcome to America .And yes this might be tongue in cheek for youse people who actually read mad mag.

Risk a real race engine on this? I doubt it.
Nothing to see here, move along...

That is the 812 (Non-coated) what I asked about is the 812D.

Wasn't responding to a question. Just showing some common lifter prices.

[Mike Gray]

The price is low because they make it up on volume 😄

Wow they come up with a lifter that will work at a reasonable price street race whatever (they can still be shimmed if no solid avail) they claim no breakin at 1/10 the price of tool steel lifter and we get complaints or it cant be done !!! Im sure they did testing . For street engines this is a blessing .
Do you know how many machine shops are either not doing flats hyd or solids and are going to roller only because of breakin ?
If these do work that just saved the flat tappet and non roller cam business .
Comp is not the only one coming out with this , there are others . But I have to say thanks to them for at least trying .
Even if they are owned by a investment co.

It will be interesting to see if they offer other engine options in the future.

On Monday 23 I ordered two sets of 812D-16 they arrived today straight form comp on the lifter it self there in no markings as to where they were made nor on the box or in the instructions, now that I have seen them for myself they are going back to Comp
My advice would be if you are selling a engine parts, and you feel the need not to say where it is made then expect it to be sent back

If anyone is interested, I checked with Comp and the 812D-16 lifters are $119.95 for a full set and they are made in their facility in Bronson MI.

I guess at that price do you really need a place of origin on the box. We can't make a box for $119. Put them in blow them up. Sounds like a good solution. BP

Guess I spoke to soon. At 119. don't think I will put them in anything I own.. I want to know if they made them from scratch or did they assemble them?
