Richard gettin’ people learned again. Biggest takeaway: Heat closes ring gap; not boost. Closed ring gap is a bigger destroyer of pistons than power.

[@fascistpedant758]

Boost makes heat, closes ring gap.

[@TorquePowerVideo]

Biggest takeaway: We never do what we say we're going to do....because boost is addictive

[@canton7180]

Power is heat, the more power a engine makes the more heat it makes, the more heat the more components expand like rings and tolerances close, I even increased bearing tolerances.

[@Faolan161]

@@fascistpedant758 - that is shallow and incorrect. Cooled boost reduces heat under same given load, therefore boost does not create heat. Heat produced depends engine build, tuning, timing, fuel ratio, fuel type, ambient temperature, what you are doing with the motor, along with about 20 more variables. I tow heavy with a 2005 Dodge 5.9 Cummins at 600 hp, 1200 ftlbs torque and under 1400 deg egt. Stock would run 1450-1500 deg and 250 hp on dyno. I guess the name says it all...

[@fascistpedant758]

@@Faolan161 "Under same given load" higher "cooled boost" pressure means greater mass air flow and leaner AFR's. A leaner AFR produces lower combustion temperatures. If you're running larger injectors, "under same given load", injection time will be shorter than that of the stock engine, also probably reducing EGT's. A gasoline engine producing More power at higher boost is quite different from a Diesel engine "under Same given load" at higher boost. With all the many variables being equal, higher boost produces more heat.

[@Turbogto_guy]

Shannon Sisk did you check the gap after taking the failures motor apart? I broke the top ring land on my piston (gen 4 5.7) and when I checked the gap, it was .025 on the top ring. Likely detonation caused my issue.

[@richardholdener1727]

Unfortunately ring gap won't cure detonation

[@shannonsisk]

TravisT TURBO GTO I did not check the gap. 15 degrees of timing on e85, although it was 11:1 compression. Who knows....it made 800whp so I would think it was heat related in the cylinder.

You're completely right on all accounts. Boost is very addictive. x lbs is never enough once it works. 95% of failures I've seen on the BMW N54 engines look like rings closing.

[@eliotbrown9662]

Thanks Richard, awesome as always. I remember an old, old article about the effects of ring gap on static compression and power and what they found was there was almost no difference up to .050! (They took it to the extreme) It also mentioned that losses in power from a lack of compression and blow by was mainly from a loss in ring tension, due usually to wear. I think you are the first that dared to suggest either of these statements are true. I'll be adding ring gap, not going to miss out on that insurance policy lol.

[@richardholdener1727]

[@finnsk3]

Very informative. I am in Australia and have a little 3L diesel 1KD 4 Cyl in my Toyota Hilux (pickup) tow vehicle. It's nearly impossible to get the big diesels you guys have with-out spending $160,000 for a ram 3500 or something. It's got a bigger custom made variable geometry turbo, bigger injectors, intercooler, tuned at 36psi of boost. It makes 750nm of torque and 325hp at the wheels, stock was 90hp, 280nm. I cracked a piston towing my caravan a few months back because my model of engine has a common piston cracking issue. Toyota actually redesigned the piston in the model after mine due to this. My Hilux is currently with my mechanic getting the engine pulled out and taken to the machine shop for all stronger internals. Should I ask for larger ring gap or just let the machine shop do their thing? Also why do people not redo ring gap.. I have blown 2 engines due to ring gap because I have no issue doing an engine swap in a car or bolting a turbo kit to an engine but I would never try and pull an engine down to file down the rings as I have no idea what I am doing. I would have to take it to a workshop and pay like $3000 to get them to do it. Even for an LS guy, you can buy 3 LS motors for the cost of a workshop filing down your rings. The engines I blew up were $500 engine... why spend $3000 getting the ring gap increased on a $500 engine. A guy gave me an engine for free if I would take it out for him. I ran 12second passes on that little 3L straight 6 before breaking the pistons. Pull the bolt-ons off, swap the engine out. The bottom end bearings went in my wife ford focus, I was quoted $6000 to pull the motor out and replace the bottom end bearings. I paid $500 for another engine and swapped it in my self in 1 day.

[@willstikken5619]

I fully expected Richard to say that when the rings heat up and expand until the gap closes that the problem is actually from when they continue to expand. Once they've lost all expansion room and continue to expand they both distort and increase pressure on the cylinder wall and that is what causes them to seize, start breaking things and ruin your day. The clarification that it is cylinder/ring temperature that determines the ring gap needed rather than boost level is an important thing for people to understand. As always good information.

[@richardholdener1727]

clarified that many, many times

[@davelowets]

Once the ring end gaps butt, it's not just drag in the cylinder that hurts the piston, BUT it's ALSO the fact then when the ring end gaps butt together, the ring itself WILL turn into a "cup shape" when it can't expand anymore (it has to go somewhere) and then it puts extreme vertical pressure between the ring lands and can actually pop a chunk of piston off the edge of the top of it that is the exact width of the ring land.

[@ts302]

Thank you Richard! I'm amazed how much the 'old school' hot rodding taboos have been crushed. These day, based on your videos, purchase a junkyard engine, with 100K plus miles(km), gap rings, boost and enjoy. I question if the taboos were based on lack of knowledge, experience, poorer quality parts, the effects of carburetors washing down cylinder walls, or if the credit belongs to great engineering & science.

[@SGTJDerek]

At a guess I'd say a combination of quality & technology. Never seen a SBC with 100k on them that got rebuilt didn't get at least a .10 overbore. Also needed to be decked just to square them up. Even a New Crate Longblock needs to be decked. Casting technology and material strength has come a long way. Add in the efficiency difference of the SBC & LS and 100k just doesn't effect the LS the same. Even maintenance, or lack there of, has a different effect.

If your cylinder walls still have the cross hatch you dont have to. But I see it as, you've got the pistons out...might as well.

[@nowayjose596]

There is also the additional R&R of the crank, cost of the ball hone (when I looked it was about $100 for a 4 inch one), and my biggest concern is that people talk about the rings seating/sealing properly in the bore, but when you hone the cylinder wall you've now erased that complementary mating surface.

Great video again! I tow with my turbo 07 Silverado classic everyday for work. My goal was to run a small turbo (67/65) and low boost (6-7psi) for low end torque. My truck had almost exactly 200k miles when I turbocharged it, I didn't touch the motor except for valve springs. That was 3+ years ago and now I have 260k+ miles on the truck with no motor issues. Now I run a richer afr and a little more conservative timing than most would but I've been on the highway under boost for minutes at a time with no ill effect. My point is that if you're going to run the tune at the maximum edge, ring gap seems more important. If you're more conservative on timing and use a richer afr, ring gap may not be as critical? That's just my experience but I'm not a pro! Side note I would like to know the ring gap on motors with over 200k miles compared to a new production motor. Have there been really tight gaps on high mileage motors?

[@tbl8560]

A 200K+ junkyard motor gaps are usually .022" - 028". They may vary that much in the same motor. It's the guys taking a 100K motor and putting some steam to without proper setup (ring gap, etc.) that exposes issues. Detonation is another element that seems to create many problems with boosted setups and self tuning.

[@davelowets]

Yes, you're correct.. Being conservative on the a/f ratio and timing will definitely benefit an engine that was a factory non-turbo application, and has stock ring gaps still. MANY people have busted rung lands on LS engines with stock gaps because their tune wasn't spot on, and they pushed it, while other people have made around the same power with ZERO issues because their tune was perfect.
