What are, in peoples opinion, the better bottom end bearings to go for when building a big power engine?.
Will be on a 2.0 running high boost.

not compition?

 

They have been proven to work at the biggest BHP levels, so can be trusted in my opinion. Cosworth do some which I'm sure are as good, but I see most builds using the ACL

 

Mahle are now doing big end bearings, in race spec & are a lot better than ACL.

 

tested ?

 

What makes them a lot better?

 

Mahle bearings are a machined tag slot, not deformed as in most bearings, no horrible part number stampings on the reverse side, where failures can start.
As Mahle took over Vandervell, these bearings are made to the high standards that Vandervell use to produce for F1 engine companies.

 

ive done searches but there still under testing

 

I have 2 sets sitting on my shelves, going into engines next week.

 

how much are they a set?
