increased cam follower wear on uprated pump

(1/3) > >>

Madone:
has anyone noticed any increase in the cam follower wear when the pump is upgraded. the new pump will obviously put more load on the follower, does the standard follower still handle it ?

pudding:
I'll let you know when I check mine at the next oil change.  I had the Loba pump fitted about 6000 miles ago and you know what? The exact same thought popped into my head when I felt how much stronger the plunger spring was on the Loba compared to stock.  "Is this going to eat through my bucket a lot quicker?"  I bet it does tbh.

Madone:
the reason i asked was i saw this video of someone fitting a roller follower, they were removing a standard follower from a APR pump after less than 1k miles and it was showing wear !, ouch

pudding:
Eeek, sounds like I'll be scheduling in a check sooner than anticipated then!   I change my oil (Helix Ultra AVL 5/30) every 3-4K though, which ought to buy me a bit more time.

Has that roller follower conversion been proven yet?  I seem to remember some heavy debating between INA engineering and some boffin bloke about the fact a roller follower needs a completely flat cam lobe, but the TFSI lobe is like a normal cam lobe to spin the bucket.  Rollers don't like that apparently.   Others were saying you need the EA888 cam as well, which makes it a bloody expensive mod!

Madone:
I read up what I could and it does look like there is some debate on the roller follower, and it didn't look like a simple swap.

The wear on that standard follower was alarming for sure !, i changed mine when I got the car, not a single bit of wear on the old one. But it's still the standard fuel pump. it makes sense there would be more wear with higher loading from the updrated pump. Hopefully that level of wear is a freek one off !
