I'm going to recommend you do some reading on internal combustion engine design and theory of operation before making recommendations to the other noobs. Study things like rod ratio, undersquare versus oversquare engine designs, quench, tumble and swirl, combustion chamber design, the effects of cam duration and overlap on dynamic compression ratio, and definitely forced induction detonation characteristics relating to mechanical compression ratios. Report back your findings for us.

Suck Squeeze Bang Blow. That's right isn't it?

No wait, that was saturday night. :naughty:

Do you have a book recommendation that covers these topics on a beginners level?

It would be cheaper to Google each of those terms and read a little from multiple sources for free. Several explanations of the same idea sometimes help perception more than a single description.

I started with automotive textbooks for theory of operation of all components and then transitioned into performance enhancing technologies like combustion chamber design, camshaft design (including all of the "Camshaft 101" lessons from major camshaft manufacturers), intake runner tuning, and all of the other terms mentioned in my other post. Then I transitioned into forced induction theory and operation. I would recommend the book when you reach that point, but not before then. Ideas build on each other.

I've been at it for awhile but still have a lot to learn. Technology and understanding keep progressing. But our little engines were designed in the 1980's using technology that was old and not cutting edge at that time. Mazda is small and quite poor compared to Honda, Toyota, and Nissan. They used existing architecture out of necessity.

Here i am quoting myself in the hopes that i will be able to see my reply so i can read the rest of the thread.

@Robb M. it's happening again.

are you running out of RAM? I can't seem to replicate. Can you please remind me your browser/device setup?

concealer404 03-28-2019 11:03 AM

HP Elitebook with an i7, 512mb ssd, 32gb of ram, nvidia quadro m2000 2gb.

Issue randomly happens on Chrome and Firefox both. Just went 3-4 days without it happening, i've had it happen twice this morning already.

Robb M. 03-28-2019 11:07 AM

Our tech guys were unable to replicate, I haven't yet either. It's def not your machine based on the above. Not even sure what info I could ask you to try and collect to help isolate this. All I can think is a rogue ad unit. I'm certain you have related threads and infinite scroll turned off?

concealer404 03-28-2019 11:16 AM

I can't intentionally replicate it either, unfortunately. Yes those dumpster fires have been eradicated from my personal preferences.

i guess screenshot if possible and let’s look for a common ad? not much of a solution.

I think its time to upgrade that solid state drive :eggplant:

OP, I would install a ral clutch first time 'round. unless you like to pull engines. I dont like to, so thats my thought.

I don't have ads. There's a screenshot of what happens in the Front Desk thread when i first notified you of this happening.

sell the unused stock clutch. save labor AND money. unless of course, more complicated and more expensive is what you are after.
