Great video!

[@EnginePerformanceExpo]

Glad you enjoyed it

[@ther1kid]

Well that was an excellent presentation. I learned and spurred a lot of thought.

[@edsmachine93]

Thank you Randy and Dan. This was such a great video. The Tech and Technology in this is so good. Covered a wide range of subjects, all related. My hats off to you gentlemen. Thanks for sharing. Take care, Ed.

[@EnginePerformanceExpo]

Our pleasure!

[@mikeg4163]

Excellent.. thanks

[@EnginePerformanceExpo]

Thanks for watching!

[@davidciesielski8251]

Hi, thanks I think.... now I will worry about things I never knew....

[@jdcustomz]

Another great video!

[@brucefulper4204]

I am "SMART MAN!" (now) Great video

[@EnginePerformanceExpo]

Thanks!

[@DURRIESVISION]

Thank guys, was an absolute fantastic presentation. I found it extremely informative. Well done and keep the info flowing. From 'down under Oz'🇦🇺

[@EnginePerformanceExpo]

Glad you enjoyed it!

This tutorial is right up my alley ... i am fascinated with crankshaft design and harmonic dampener engineering . The use of Tungsten for Rod bolts was eye opening and thought of using it for Rod caps ... hmm ... just a thought ... We are only scratching the surface here and same for main and rod bearing compositions . Thanks again fellows !!!

Phone rings,....you buy a carton of beer. That's the rule in Australia.

[@samstewart4807]

hi, how much of the high rpm oil pressure reduction at the rod bearings is due to the centrifugal force placed on the crankshaft by the high rpm??

[@amichie67]

Great video. How is it that in a normal crank you avoid drilling balancing holes to maintain the strength and integrity of the crank but towards the end you discuss bolt on counterweights with no apparent loss in integrity. This is a bit counterintuiative.

[@jeepin270]

thanks for doing a 2nd video, i couldn't even finish the other bearing video because that other guy is so annoying.

[@samstewart4807]

hi,is any of the crank flex due to detonation?

[@jims2286]

The higher the RPM, the more centrifugal force on the rod bearing more than the main bearings throwing the oil off, which is why you don't want a cross drilled crank oil holes.on an engine that revs over 7000 RPM.

[@jims2286]

Love this video. Keep up your awesome work. Thank you

[@454ho]

Excellent thanks guys, what bearing clearance do you recommend on comp eliminator engine 10000rpm 1.850 journal?

[@EnginePerformanceExpo]

.0018 to .0020

[@EnginePerformanceExpo]

And thin oil…

[@chrisstavro4698]

I work in a machine shop and we balance cranks. The two major takeaways is drill no more than 1/2", and make sure the unbalances are 180* apart. I haven't seen swiss cheese like your example come to our shop, but pretty butchered.

[@causeimbatmaaan]

I absolutely don't believe him that the rod journal on a pro stock crank is less than 2.0".

[@EnginePerformanceExpo]

1.880 journal. Dan knows because he sells them their bearings.

[@causeimbatmaaan]

@@EnginePerformanceExpo ok, that's impressive. I knew they had been as small as small journal but the last time I was involved in any pro stock was two decades ago. Sounds like using Honda bearings now.
