What is ignition timing ?

[@Hoppysjunkyardrally]

20 year's I've struggled with understanding timing.. 10 mins and I'm blown away! Great video! Thank you

[@FoxRob93]

Great explanation with visual references. I might have to send this video to customers who do not understand how ignition works.

[@Wings65288]

Great vid thank you. I liked the part of explaining how a rod can get bent.

[@GTRliffe]

do another one of the simple but important vids about the crank position Show us what’s the correct spot where the fire should happen

[@Alkyhaulic_91]

This is so much more info than just having grandpa say “lock it out at 42 degrees and get on er’ down the road.”

[@Nickolas.Runkle]

Just sbc things haha

Great explanation of the timing concept Devin. I have been working on cars and been involved in the performance scene for 38 years and while I understood the concept prior I think you did a great job of putting into lay terms to better educate those that either didn’t know what it was or how it truly works. Your content always amazes me as you strive to share your knowledge with the new guy on the block. Can’t wait for some new content on your Mustang that seemed to get pretty sick on Sic Week.

Amazing explanation … 🤝

[@BigMikesGarage]

Great job explaining this. As you were describing TDC I was thinking "dwell" right when you said "there's other things like dwell that we aren't going to cover here". I would love to see you cover PWM bump, and how the htz and time function. I have the basics and can make it work, but sometimes it's still a PITA to get right when you make a big tune change. Thanks for the content.

[@theholleyefiguy]

i made videos on that lol

[@BigMikesGarage]

@@theholleyefiguy great, I'll go look for it. Thanks!

[@GoodSpeed150]

Excellent video. Thanks for the wealth of knowledge on different aspects of racing. We all definitely appreciate it!

[@BostonPhiri-tg7bw]

How do you identify the degrees during the ignition timing

[@shautohaus]

Great explanation. Thank you.

[@montenelson2917]

Great content. Thanks for sharing your knowledge and helping others advance with there's.

[@approachingtarget.4503]

Good explanation.

Great video, good visual.

Great videos!

The aluminum becomes fuel. It'll burn that shit. Made me roll. Haha. I already know this ign stuff but I figure since it was you doing it I'd see some beautiful sbf parts and you didn't disappoint. All those parts are art work and it's almost a shame to cover them up in the engine. Your tool box is super clean and it makes my ocd happy. Plus an extra view and like for an engine builder and tuner i like always helps out As far as advanced tables and spooling up I will soon find out if I'm worth a crap at it. Lol

[@airselectricalcontractors842]

great video - how do you know what percentage you need - i have a 1995 landcruiser thats distributor was just changed ??

[@robfling4107]

Thank You Great Vid!

Terrific video!!!

[@kevinteeter7996]

Nicely done!

[@alwallis2000]

Great video !!!

[@ernestorr5664]

Would lighting the candle (blue flame )be due to little timing to much fuel?

[@ericmiller4285]

Being lucky enough to work in engine development with combustion analysis software and cylinder pressure transducers reveals most people have no clue how ignition timing works... or how internal combustion engines work in general. People would also be disappointed to know many "tuners' dont really do a very good job... Throw in a base tune, tweak a couple things to make sure AFR is in check, aaand here's your bill.

[@b.c4066]

That's the biggest issue, I live within 75 miles of half a dozen chassis Dyno tuning facilities, and 3 engine Dyno cells. And half of them are clueless. The one that is top notch is Steve Morris engines, and he will not touch it unless he built it. Don't blame him, he doesn't want the headache unless you buy it from him. One things for sure, if you want high power with any degree of drivability and reliability physically building it is just the beginning, tuning it takes skill, time, and knowledge. The ones that really understand aren't cheap. And you probably won't get on their schedule for a month or more. Guess what I'm saying is it's hard to know who to trust, and there are not many ways to verify the tuners skill level other than word of mouth.

2:38 me at night playing with my piston

[@motoweenies4431]

Great vid, I knew most everything in the video already, just not so sure on the material science of why when the cylinder is it out of fuel, it resorts to torching a head or piston. In other words, why doesn't the combustion just run out or cease to exist?

[@theholleyefiguy]

Cause it's still under pressure

[@frankkatsenis3812]

Good video, could you explain or make another video on why on race engines you add timing and when to take away. Why more timing makes more power the snap of the piston. Everyone talks about snap of piston I kinda get it.

[@theholleyefiguy]

I won't be making any videos with tuning theory as people will just grab numbers and sling them in then blame me. No thanks

[@tundeclipse]

Hope you see this comment Devin, Been going through your videos on advanced tables and boost building on the brake, how to offset timing to damn near 0 to build boost faster waiting for the light. To me it seemed like it would be harder on the rod to offset to 0 or whatever number you want to offset it to, leaving more unburnt fuel to 'press down on' the piston head where now, after this video, I kinda see it as opposite where it will just exit the valve leaving you with a rowdy internet famous flamethrower. You bring up a good point on too much fuel to create a potential hydrolock situation. In your personal educated opinion, is there a level of offset timing that creates a (well call it a danger zone) amount of fuel left over that creates its own set of hazards for the parts. Seeing TurboJon and a few other guys setting up advanced tables and walking through their program and dropping to damn near 0 on the brake.. at what point are you now saying leave some timing in it for safety...or does that not really exist. Itll be my first summer at the track playing with more advanced things than a simple time/boost graph and would rather ask a question and learn than end up pulling the block and learning the hard way. You just walked me through the transbrake wiring in another video by slapping a pointer on a piece of paper so i'm not asking for another big spoon to be fed from here, just wondering your thoughts before I offset something to 0 for the shack chicks to see a bunch of unburnt fuel being sent to the sky.

[@theholleyefiguy]

if it falls off the chip from pulling too much timing too fast its wrong, if its staying on the chip and not building boost fast its too little lol. as far as safety goes, dont get too far into the negative timing values

[@tundeclipse]

@@theholleyefiguy Sounds good! thanks for the response, me and a buddy will be playing with our setups this summer (KEEP READING) and youve been a huge help. appreciate your time!

[@BlownCommodores]

Explosions are bad, controlled burn is good. Under normal running conditions the mixture in the combustion chamber does not explode or go bang, if it did the engine won't be doing many more rotations. It might help to explain that ignition timing is used to achieve the optimum peak cylinder pressure timing which should be just after TDC and the piston is heading back down the bore.
