Why Stock bearings may not be best for you race engine.

Bill and Alex discuss the different needs that race engines have when it comes to racing engines.

I love this guy. Wish he was my gramps. I could listen to his stories all day.

[@BoostedPastime]

We need to keep Bills knowledge alive.

Thanks for making this video it really did shed some light on bearings. normal logic would think that you need a harder tougher surface for high hp. I'm still trying to wrap my head around this concept, but I'm smart enough not to argue with professionals. and I'm not just talking about the guy in this video that explains some stuff on bearings. Its hard to grasp how increasing bearing tolerance and using softer bearings makes a drag engine stay together. I'm just doing research on building a short block that won't start knocking after a few months of racing.

embeddibility. if it doesnt have it theres no give to the surface to "take up" that small piece of metal. a hard ass bearing wont embed it and take out the crankshaft which is expensive vs taking out the bearing, which is not as expensive.

They didn't mention how long the babbitt coating lasts on a 900 HP motor but on top fuel they did. I was curious especially on those 24 hour endurance races.

[@lazaromarino9200]

Very good question! I'm also curious about it.

[@bernardwarr4187]

Love the top fuel explanation, brilliant

[@steveashworth6707]

Mahle is just down the road from us!, I used clevite 77 bearings when I was a kid!.

[@lazaromarino9200]

Learned something today and I don't feel bad about my bimetal engine bearings I put in my street 350!

[@bernardwarr4187]

Thanks guys, very informative

[@mclarpet]

Are they anything like that bloody hard aluminum-silicon alloy used in cast alloy pistons ?

[@Keyno77]

Nice factual video, other videos and reports dont put it like this wizard. 600hp and up go tri-metal.

[@boosted2.4_sky]

1:53....but for a good street /race car making up to 600hp...use Si/Al bearings. .

[@pauljanssen2624]

That's what happened with my race motor when I used to drag race at Fremont raceway in California it would squish the Babbitt out the sides

[@chevroletbelair1]

there the best? not the p series . i have my 2nd set in house because the first set had geburs and litlle iron flakes in them .well the second set was also bad and had tesame problems. where are the p series made?

[@e36racer44]

Just got my MAHLE rings, ACL race bearings and bmw bolts ready for s race engine build

[@andrewjohnson3622]

I wouldn't touch Clevite bearings nowadays. I would love to see this brand go back to making quality bearings.

[@XenoSeven86]

H series good for 500hp street LS?

[@ralphtaylor787]

I had a momentary rattle on hot start up in a Gen1 Chevy 5.7. All of the rod bearings were factory standard. I replaced them with standard bearings and now I have a slight continuous knock when engine warms up.

[@antonc108]

This grandpa is the real deal!

[@Bizarado]

That awkward moment when mahle bearings are oem for subarus lol

[@boosted2.4_sky]

THEY'RE OEM for ALOT of platforms... perfectly fine until they start making real power...

[@seancarroll146]

F1 cars do not make 10000hp, lol

[@doughopkinsjr]

He didnt say F1 he said top fuel and by most drag racing calculators it's over 12,000
