Steve Tech ---Part 4 Camshafts

Here is Part 4 of camshafts
It was pointed out that I started to babble a little bit, sorry if that is the case.
remember some things I say someone else may have no clue or never heard.

Check us out below!

Hi Steve. Feel free to babble all you want. It shows how much you think about the interrelationships between everything. One observation that I would like to make is that I don't look at the engine is an air pump. I always think of it as an air consumption device. Turbos and blowers are air pumps. Engines consume the result. A pump feeding a pump is a 2 stage pump. But in reality we have a pump feeding a consumption device. That's how I look at it anyway. Personally it helps me understand what I am trying to achieve and what I need to do to get there. Love your videos. Regards Greg

Good videos. love his simple “next door neighbour persona” yet VERY educational

Love this series ! You put them out and I'll keep watching Thanks Steve !

[genemounce]

These 4 vids have made me rethink my entire set up lol. Appreciate it chief

[bigblockjess]

Thank you again. Especially for doing these series. I learn more every video. I will be definitely calling you very soon about some stuff. Haven't decided if im doing a HEMI or LS yet for my build.

Great, valuable technical information, spelled out is a way that makes sense. Thank you very much.

I love learning more about camshaft voodoo. I like knowing the different designs with the pros and cons of them. You do a fantastic job of conveying the message you intend to.

[ronhodgkinson]

More, more, more it never gets old. As a much older fart than you I enjoy listening to them. Now ledge is never boring

[tjeffjenkins]

NICE, thanks again for the great overview!

[CaptKirk-rbvh]

Such great info!! I really appreciate how you take the time & break stuff down in laymen’s terms so is with little to no experience can understand & learn!! Thanks Steve!

Steve, I love your Dog. How about a part 5 and show us one of your cams on the Cam Doctor? Would like to see that "Asymmetrical" closing event. Thank you.

[jorgecamacho]

Awesome, thank you for the great learning sessions, be Blessed .

Great series! I’m a bit concerned about those square corners on your acceleration graphs. As acceleration is rate of change of lift (as the camshaft rotates), jerk is the rate of change of acceleration. Square corners indicate infinite jerk, massive changes in acceleration, which are not good in a dynamic system. Your lash in the solid roller world should be taken up “gently” by a ramp in the lobe profile—unlike a hydraulic roller, which is supposed to always be in contact with the lobe. These are pretty minute changes in the lobe, but really matter if you’re spinning a heavy valve train at 8000 rpm. I’m obviously preaching to the choir here, but it seems to me that glossing over jerk is limiting the discussion. In spite of that comment, this is a great series! Thanks Steve!

N/A 🤣 Pro Stock guys and their 500, 000$ a year budget on throwing new Ti valve springs at it every run🥸🔫 🤞 what about boost effecting intake seat pressure helping the valve open and turbo drive pressure slowing the piston down when turning the corner @ TDC on the EX stroke. My father started me early around 11-12 doing bottom end on his TA/FC rolling new upper rod bearing in it every run trying to hit the bearing squish sweet spot around .003-.006 with a hi helix roots, Wipple, or PSI screw. The first time I worked on a Hemi with hair dryers I couldn’t believe how much having drive pressure helped the bottom end. The same motor with turbo will go 20-30 runs with even having to pull the pan !
