Their victories mean more power and performance for guys like me, I'm excited for them. I'm getting ready to have their piston rings installed in my 6.7L Cummins.

I know, right?

It's crucial

Thanks for the suggestion

Thanks!

Thanks!

Glad you think so!

Thanks!

Thanks!

Thanks for watching. We actually found a paper from Sunnen published back in the early 80’s that showed this same strategy. I guess the old adage that there’s nothing new under the sun applies here as well…

Thank you for responding. My results came about from building and tuning RB26 engines. One could do some light mods and make close to 1000hp without opening up the motor, (other than cams and cam timing), and have no problems with breathing or piston or ring bind. Then when we built them with the American recommended clearances, all turned to sh1t. Breathing so bad one can't keep oil in the motor. Stopped and asked myself some questions......did some thermal expansion tests....and started building with OEM clearances and very fine honing. Problem solved. Applied the same principle to many American and Euro motors I build and the results are the same. Never had a problem. I do however add clearance depending on my reading of the customer as they are the biggest problem:)

You know that is a good point. Dyno Don and Total Seal are not giving away newly discovered secrets. Each of them have to stay ahead of their competitions and you are not going to hear about the leading edge stuff on KZfaq. They are going to keep them to themselves for at long as they could. That is no knock against them, but the nature of racing and business. For most of us amateur motor heads, this is good relevant info.

@@slicedbread9003 You would be surprised how little we are actually holding back.

@@TotalSeal I REALLY appreciate these guys sharing their info as I'm no one and have never heard anyone give this kind of info. At the time of my thermal piston expansion test......and I've done a number since, I tested oem cast vs half a dozen forged, (also tested blocks. Cast and aly), all various brands so I don't know the material used, but all the forged ones expanded LESS. I have built two of my own motors with 0.0005'' interference.I had to be very gentle on the running in and make sure the tune was spot on so as not to shock the pistons with temp. There was no problem with either motor their whole time cycle. Building a motor like this means one can re-ring a motor a number of times with just a rehone. Piston skirts can be recoated for about $25 here to regain the clearance desired.

Thanks!

Thanks for watching!

Current NASCAR engines pull 24 inches of vacuum at 9,000 RPM

@TotalSeal wow I didn't know that either so when I've took all the Engines to the machine shop over the last 27 years. They've all been done wrong. Then is what you're telling me!! Mind blown !!

@@rickybailey7123 If the engine is a dry sump, it can run vacuum for a HP advantage.

What STOPPED These Pistons From FAILING? kzfaq.info/get/bejne/acidZ5yUpp6ok5s.html

Thanks for watching!

We have some trick stuff!!!

That’s why Brad is the man!

Noted!

That’s very kind.

Agreed!

This specific hone is not appropriate for street engines, unless you are running on E85 and boost.

@@TotalSealwould it have to be full E85? I run E50 on a boosted engine

@@aikidokamksless Rvk for E50. 65 to 70 on the Rvk would be good.

Not yet. We are still field testing them.

We’ve seen the more consistent the cross hatch is from top to bottom, the better the engines run.

Yes it is!

That was out of the hone!

Yep, it does

They can be helpful

Anything. It's a digital microscope.

140 grit diamonds

Why can’t I see?

That’s 0W-50 Racing oil.

With the 600 CBN, we are not measuring stock removal. Instead we are counting the number of strokes. 8 to 12 strokes with about 20% load typically does the job.

Not on this engine.

Yes! The Engine Performance Expo LS has Gas Ported Gapless rings!

Sounds like they are running the pistons tighter in the bores than normal. Not sure how good this would work in the real world where engine temperatures could fluctuate in hot weather and may cause the pistons to expand and lock up in the bore. They said there was more information to come. May be this will be all explained later.

​​@@GaryH-pw9cm, in another video, they said they can tighten the bores slightly, because there is more oiling available in the crosshatch. They also said they ran it right up to 8 or 9000 rpm. Unless there's other problems keeping the fluids cool, it's hard to imagine worse conditions than that.

He said itza $ 70,000 engine. If you have to ask, you can't afford it. 🤔

Ball park is $500

Also the improved wear resistance throughout the motor - piston skirts, rocker pivots, valve guides, rod bearings, cam chain . . . . less wear is longer life.

Very different because the application is completely different.

@@TotalSeal I get what you guys built that engine for, but I'm wondering do you sell piston ring kits for engine rebuilds that aren't race motors?

@@russellweber3466 Yes we do! Contact our technical sales department for details - 623-587-7400

I wonder how much of this could be applied to a stock cast iron block engine. The way I understand it is that the additional vacuum in the crank case is pulling the first and or second ring down against the piston causing a better seal of the rings in the piston. And the better seal of the rings is creating less blow by intern causing a higher vacuum in the crank case. So both of these help each other. Also using gas ported rings and this new hone procedure at the same time. I would guess the crankcase vacuum is from a vacuum pump. Would this apply to a PCV type system if the incoming air was restricted? In their excitement some of the information presented is not very clear. More diagrams and animations would help for people like me.🙂

@@GaryH-pw9cmII wouldn’t doubt that the guys are running a “power free” style system of vacuum pumping that relies upon the “Venturi Effect” similar to what you’ll see on other race engines. After all, a vacuum pump is rarely seen outside of diesel applications and then it’s usually reserved for stuff like the power brake when it’s still vacuum assisted AND the HVAC controls.

Yes, this can be applied to iron block engines as well, just a different variant of the hone.

It gained everywhere up to peak it seems.

There was a power gain, but they were also detuning the engine at the same time.

@TotalSeal doesn't that mean overall more efficient?

Why

its a video about suction

LOL

That’s not fake. We truly love this stuff.

@@TotalSeal I understand this but it comes off as fake. It looks bad! I'm not saying stop being excited... But the OVER the top expression makes what you guys do look fake! Hence the "Street Outlaws' comment...

@@TotalSeal kicking goals blokes !!! Good stuff from down under you pair of mad scientists hahahah ignore this bloke who’s not only unable to see the genuine work you pair have accomplished during your march for the holy grail let alone how satisfying it is to see a result of this kind and with such a distinction is truely a well earned victory and milestone if ever I seen one. Congratulations to the both of you and thanks for all the hard work you both do, words couldn’t describe how helpful with my projects your work has been. Dedication like this is how we progress and move forward and I acknowledge the almost all consuming obsession that this level of dedication is at and the sheer strain it can have on all the other aspects in your lives and I thank you for this level of determination to see the limits of this path and am looking forward to what new things you will bring to light along the way guys keep it up !!!!

@@aussieblokeiiikii9169 Thanks mate!

That’s the purpose of your PCV system. It’s also handy for preventing oil leaks on the driveway.

Oh yeah!

@@TotalSeal m My only personal reference is my own engine..... Probably +25lbs pressure. 🤣

@@ToddAdams1234 I understand with a PCV system. Are they using a PCV on a 900+ HP engine. 😳
