Kevin , the saying is " The shoe maker always goes barefoot". We all appreciate you taking us along . We're gear heads so we love all your content! Keep it coming!

[@ForeverNeverwhere1]

The phrase is " the cobblers children have no shoes" and has a very different meaning to what you think, it suggests those with an ability to do something refuse to help those closest to them.

[@Robalo-2660]

@@ForeverNeverwhere1 That's your phrase not mine . I guess it just depends on your mind set , doesn't it? I think mine applies better to Kevin's situation.

[@CCDzine]

@@ForeverNeverwhere1 That is the original phrase but it means that while the cobbler has the ability to make shoes for his children, he is too busy with customer orders to have the time for making his children's shoes.

One of many things I really enjoy watching Kevin‘s videos he’s not so secretive on his methods of tuning cars like most race car mechanics do but I am sure Kevin has his own special tunes on race day 👍

[@netburnr]

Same with his life lessons building cars and fabricating parts. He shares his wealth of knowledge and thats why this is such an amazing channel. Thanks Kevin and team

[@russellharper3027]

It’s great watching a legit racer/fabricator getting into detail of youtube. It seems like you’ve been involved in a lot of different kinds of racing. If you see this, out of curiosity, have you ever helped out on or been around much sprint car or midget racing? There’s a massive void of technical info/videos about that kind of racing on the internet. If I was still racing I’d strongly consider sharing that stuff myself. Love your channel.

The Plug Whisperer. Don't know what you charge for a tune but it has to be money well spent. Thanks for the upload.

[@rmcnasty7319]

Hello Kevin Reading a Plug Is a Good Idea. If u see Silver/Gray Specs of material, on plug. It's your Piston Melting. Could be Timing to high, or Running Lean. Running Nitro Methane also does this, Just before piston Melt down. If running Racing gas , at the end of race , is the best way to tell if it's to Fat or Lean. That's why I run methanol. As long as motor is 180*F @ launch & stays under 210 @ top end. I don't have to Get out to read a plug at the end of the track.

[@michaelmeyer8493]

The more I watch your videos... the more I want to build something. Then you start getting technical and I'm like yeah that's alot of information to tune something. Great stuff my guy!! And a killer bowtie!

[@jasonsell8523]

Hey Kevin when you're trying to show something so close up like those spark plugs you'll have to set a manual focus since your camera isn't adjusting correctly. Loved the video! Badass sleeper of a truck 👍

I'm jealous. Wish I was closer to Kevin, so he could button up the loose ends on my truck.

[@anomamos9095]

Have you tried those multi electrode E3 or other brand plugs? A lot of people don’t understand spark plug temperature ratings. A cold plug has a very short well between the tip of the electrode and where the ceramic contacts the inside of the metal part of the plug. A hot plug has a very deep well, upto three times deeper than a cold plug. The actual purpose of the heat range is to allow the plug to get hot enough to self clean and has nothing to do with the amount of power the engine will make, Except if the plug gets too hot and causes pre ignition without spark. As combustion chamber pressures and temperatures increase due to boost you want to run a colder plug to prevent the plug from getting too hot. As for plug gap, I was always under the impression that as the pressure went up the electrical resistance of air went down so you could run a wider gap with boost. But apparently it had this backwards and you need a smaller gap the higher the boost, but then you run into the problem of not enough size on the ark to properly ignite the fuel, which is where the advertisements for multiple electrode plugs make their claims.

[@KSRPerformanceFabrication]

Multiple electrode plugs are nothing but a sales gimmick. Electricity will always find the shortest/easiest path to ground through and hanging a bunch of extra ground strap material in the chamber of a race engine is a great way to introduce detonation and damage an engine.

[@wadestewart901]

The tuning content is Golden! Not to give away your secrets, but this is great info!

[@bullittdog4352]

Mid 9’s on a truck that weighs close to 5,000 lbs. is flat out hauling. Kevin it was a rotten thing to do when you didn’t show where you started from hp wise..its always fun seeing what a proper tune equates to in power gains.

[@mattquarles7029]

cant see why reading plugs would be bad. it is for sure a good trick. i bought an 03 tahoe missing on what sounded like one cylinder. come to find out it was 2 but when i pulled plugs i noticed plug 1 had 0 timing mark at all and plug 5 had a very faint one and the rest were in the exact same spot and decently gray on hte timing mark like normal. pulled coil packs and sure enough cylinders 1 and 5 had 0 change when unplugging. there was obvious indication of this when reading the plugs in my case.

[@jackcompton8752]

He's done gone back to the future!

[@surfski1959]

Hi Kevin, I was curious about the Puff of Blue smoke that comes when you lift off on the Dyno, is that from valve seals or combustion chamber residual fuel and a little oil.

[@KSRPerformanceFabrication]

One turbo is a little tired.

[@GrahamDallas]

Never been this early, but always love when KSR posts a new video.

[@yellowlt1ta]

I've seen a lot of issues with the provided Holley terminator wiring harness. Also the ignition coil power and ground's are very undersized. It's best to rewire with a relay and get power from battery.

Great video Kevin. Curious if you also read the AF mark down on the porcelain? All you showed was reading the timing mark on the strap.

[@KSRPerformanceFabrication]

I do with gasoline engines. With ethanol fueled combinations, there is a pretty broad range of acceptable Air/Fuel Ratios for making power. I run on the rich side of what I feel is safe and then play with timing to find safe power.

[@andrewcammer2535]

Absolutely love the content - really good stuff. One thing that would be awesome - figure out how to get the camera focus to work for you on the close up stuff. I LOVE the spark plug reading - but they are super blurry. Also - I loved that you touched on making power past the peak. It kills my soul a little more ever dyno chart I look at and they end the pull as soon as the thing just starts to roll over. IMO, you want to see as far beyond the peak as you can safely pull the motor too, probably limited by your valve-train in most cases. An informed decision on shift points is a lot easier with dyno data to back it up. This is especially relevant to stick shift cars, which have MUCH poorer shift recovery, and in turn need to run out further past the peak to see their best average power.

[@hommie789]

Kevin what air/fuel ratio did you get on the dyno, during the pull, after moving the sensor?

[@KSRPerformanceFabrication]

At WOT, the readings were the same due to the amount of exhaust coming through the pipe. The issue that was corrected was at low engine RPMs, the O2 would still read something "normal".
