KRE show us the inside of the #8 Bathurst engine

[@etsiej]

Thanks BJR team. Really like your easily digestable engineering insights.

[@vortexau]

Very cool insight for the fans!

[@MetalMania3DTV-TAS-AUS]

A legend of Aussie race car engines, had 1 of his engines in my V8 Sprintcar, absolutely the best, was cool seeing him again as been many years since we last spoke, Cheers🍺🍻 KC Cradle Mountain Tasmania Australia 🇦🇺🤝🇦🇺😎👍✌

[@Ckktopa]

Great insight, thanks for sharing BJR. Love your videos!

[@rhettcorbett3346]

Awesome video again Brad. I wish some of my Ford teams would do videos like this.

[@davidwynne3289]

Great video Brad.

[@hemichump]

thanks BJR team for the video just need to auction of the parts

[@gregreimer5714]

I noticed that the heads are rectangle port ,do you get the 5.7 by destroking and larger bore compared to 5.7 ls engine

[@markbrophy4331]

Getting oil temperature and pressure right is a viscous cycle.

[@dinosshed]

I see what you did there

[@PUNCHARD800ftlb]

hahaha i just lost 35psi thru my relief valve

[@obiemichaels9675]

Excellent videos Brad

[@craigritchie1933]

It's common practice to fit a Torrington end thrust, bearing into an engine destine to be drag raced, due to the thrust the torque converter puts on the end of the crankshaft. This should practicaly eliminate any chance of further failures

[@NeilJable]

It would but it isn’t within the rules.

[@craigritchie1933]

@NeilJable its pretty simple. Change the rules , it makes no difference to the power output but could save the teams' 10's of thousands or more dollars in engines each year

[@MelodyMan69]

Took the word right out of my mouth. Torrington. Been in use since the 60s on US V8 Motors built for bullet proof usage.

[@chippyjohn1]

Was thinking the same thing. They already use needle roller bearings for the cam.

[@JimOHalloran]

I know at the beginning of the season the engines were all built and given out to the teams at random. Does the team "own" the engine now? I'm wondering if that head will go into a "pool" engine that will potentially go to another team, or will it definitely come back to BJR? Related, when BJR sends an engine to KRE for overhaul, do they get the same one back afterwards, or just an engine from the pool?

[@RMinOZ1]

The majority of that engine is going to the tip, mate. !

[@RMinOZ1]

KRE Own the engine and lease them out.

[@RMinOZ1]

...and yeah the heads will be damaged. Rocker covers will be oK, though.

[@timjohnun4297]

@@RMinOZ1 Ken literally says, in the video, that 2/3 of the engine is salvageable. And that the damaged head will be repaired 🤷‍♂

[@gerardcrabb4556]

He said repaired engine would be a spare for BJR...

[@StephenCroxon]

If this engine failed due to excessive thrust why didnt any other LS engines fail? I would assume they are all using the same clutches or very similar

[@tturi2]

thank you for this insight😊

[@ickisdogg3779]

Looks as bad as my old 202 race engine I used in my Torana, oil pump failed and it just went bang, had to junk whole motor, nice work BJR, an excellent series

[@ReCycledCycler]

Man alive that block!!

[@rodglease4142]

Very interesting brad

[@graemecatty9921]

Silly question (maybe). Are their warranties of some sort on these engines as the repair bill would have been rather exy.

[@pammotorsport9743]

That would make a nice coffee table.

[@3UZFE]

How much of these engine is OEM original, is the block completely original and everything else changed?

[@BR69843]

Chevrolet Racing have just today uploaded a video "Part 3 - KRE Race Engine Series - Road v Race Comparison" that'll answer exactly this for you mate

[@horseshoe182]

could i buy that damaged engine block? i,m in sydney.

[@chopperking007]

2 valve push rod....do the mustangs use their 4 valve OHC engines ?

[@jasonevans1756]

Wow thanks 👍

[@7071t6]

So therefore the main bearing cap was installed incorrectly or the wrong tolerances when it was made, thats what caused the shaving of the metal particulates to come off the main bearings ,plus the engines have very fine tolerances ,which makes it even worse when they do fail, especially oil pressure loss, but its what caused it in the first place for metal to metal wear, then something was not put in right IMO ? Also thanks for the upload, go Chevy. 🚗🚗😀👍✌👌

[@cedhome7945]

That block is going to make a great coffee table, at least it will make a few bucks back for you 😜

[@dylanangel2870]

"well put 2 thirds of the engine back together" brad: i dont want that engine

[@JimOHalloran]

Given the massive damage to the block I'm surprised so much is salvageable!

[@Danger_mouse]

Why would the crank thrust bearing fail on a brand new race engine? Is it poor lubrication, poor assembly, incorrect clearances, or the wrong parts for the job? Nothing special about a crank thrust bearing in an alloy block engine, even with a big heavy clutch pressing on the back of the crank.

[@Danger_mouse]

@@BigA-zx5io Sure did, but it was not explained. I'm a mechanic with 40 years in the trade, including building my own rally cars. Never had a thrust bearing fail using the correct oil, fitting quality parts, keeping the pressure up and setting the clearances. Again, I ask, what made the thrust bearing fail?

[@Danger_mouse]

@@BigA-zx5io Definitely need to look at the engine design or the assembly of it if that's the case. Every rally car ever built dumps the clutch on each new stage multiple times a day, almost every top 20 car is AWD with massive amounts of traction and almost all will be ally block. Also, releasing the clutch takes the load off the thrust bearing, the load is there while the clutch is depressed. Seems like there's not enough oil on the bearing, or the material is incorrect

[@brettpowter6010]

Narrower thrust face than earlier engines and super heavy clutch diaphrams wouldnt help at all i think..bit of design fail id say..

[@JayGuitars1]

@@Danger_mouseI thought I heard him say the mains were last in line for oil, if so, expect more kablamo in my opinion.

[@MrHarvey1301]

if thrust is an issue is there a reason why Torrington bearings aren't being retrofitted?

[@blueyhis.zarsoff1147]

2 piece torrington flat roller...dont see that very often

[@TomSmith-cv8hk]

Hi Brad, that's a lot of thrust damage, sure there wasn't an instillation error ? 😁Not that the engine was ever going to survive, BUT a blocked filter from a disintegrating thrust ? Was that the return filters blocked ? Or the feed filter ? Seems they could do with having a bit more capacity.

[@JH-jo9wt]

What happens to those parts? Would love to buy that stuff

[@jamiebeverley9705]

Hi Brad, whats the cost comparison on these new engines to the out going engines ? Thanks for the video's Brad, very good indeed 👍

[@alro2434]

Thrust failures are rare enough and do not happen without cause, poor assembly or really riding it. And definitely not enough to CLOG a filter!

[@corporalpunishment1133]

It's interesting that the thrust bearing failed since the sequel gearboxes in v8 supercars don't use a clutch to shift gears.

[@eklein3904]

Yep, if there had been plenty oil….things don’t explode…more likely oil supply or clearances…

[@dinosshed]

I'd have thought 2/3 are going in the bin. Crank, rods, pistons, block.

[@mrwolsy3696]

Expensive boat anchor.

[@stusue9733]

Going to need a smaller boat ;)

[@gb4408]

Couldn't you machine the crank to accept a touring torrington bearing

Thrust bearing problem my arse

[@clevo351]

Someone didn't check the trust bearing clearance properly

[@vonshnoodle]

To sum up, it's proper f*****

[@RMinOZ1]

As he said wouldn't have happened to the previous series engine...so that's a total loss to that team and money not well spent on all levels. To get paid first they must finish. Bring back the previous cars ...entirely.

[@KaneTerry]

$$$$$ video, so does BJR have to foot the bill or Supercars as it an engine from a pool and a control part. That block & crank are toast

[@tturi2]

they're leased for $60,000 per season I'm pretty sure,

[@trimat2016]

@tturi2 $60k doesn't seem enough to take responsibility for engine failures. Too many ways the teams could stuff up and damage the engines. Ignoring falling oil pressure in this case being a good example.

[@VS97VS]

WOW what a mess

[@peterschaefer2946]

iam not sure about all of that

[@38skippers]

Leg out of bed

[@marksmith2726]

Well i don't think Ken was overly impressed with this engine or his comments! First of all how much pressure is on these clutch plate cause this is not normal for a LS to do this even at over 1000hp, Secondly if the oil pressure was dropping 3psi per lap why didn't the so called engineer pull the car in and investigate?? As far as I'm concerned this is on BJR and there stupidity at not looking at critical engine data or a simple oil pressure gauge.

[@dons1932]

Bro did you even watch the video? He literally says what happened verbatim. The PDM was overriding and resetting the alarm - yes/no, yes/no - because it wasn't a critical enough drop and still had decent enough oil pressure. By the time the alarm actually held, it was already too late. Just because you have failsafes, doesn't mean they'll save you an engine. At 7,500rpm by the time the alarm flashes that the oil pressure has dropped, the engine will already be dead in a single second. You can't instantly stop that rotation and lock the thing up to prevent damage. EG: If you had an alarm to say the car is on fire. When the alarm sounds that the car is indeed on fire, that doesn't mean the fire magically goes out.

[@marksmith2726]

No i didn't ? Thats why i commented on the video, if the PDM is a issue put a bloody manual oil pressure gauge in, if that was my car and dropping like that per lap it isn't hard to see there's a issue going on. just sick of this BJR rubbish.@@dons1932

[@tomnewham1269]

A 1000 bhp LS isn't running a manual gearbox, they are using a torque converter which is totally different to a clutch like they are using in a V8 Supercar.

[@marksmith2726]

Well not all the time there are manual 1000plus hp LS comabo out there.@@tomnewham1269

[@tturi2]

​@@tomnewham1269unless you're a real racing driver you keep It manual haha

so it only lasted 18 laps a engine built to do over 1000klm hmmmmm still be getting a better engine builder my personal opinion

[@joshiek7839]

It did 6 hours of practice and qualifying before that

[@chippyjohn1]

Don't know why we are still using junk US engines. Some inline 6 turbo engines should replace them. Pushrods were obsolete by WW2.
