I’ve only just found this channel and subscribed, you’re doing a great job Brad the behind the scenes and explanation of the various parts are most welcome and very informative.
I see there are more and more viewers to this BJR Channel each time I watch, and many of us are learning along the way. Which leads to more BJR Team supporters like me.
Thanks BJ , still loving the thorough explanations. You’ve saved me from leaving Supercars 😅. I’d love some content on how teams run to. As a business in a team sport.
Hi Brad. I'm a very much a casual Supercars Fan currently, but have been watching your videos on the behind the scenes workings of a Team religiously. Very interesting stuff. This video was great and I think getting close to the perfect length for your 1 take style segment, I've often felt that some of the others were a bit short.
Question? Putting aside tyres and brakes, I'm amazed how quickly these cars warm up after sitting around forever on the grid, with only one warm up lap. Especially on short circuits. Not only motor, but clutch, gearbox, diff, etc? And all the oils warming up?
Interesting that the old ZB filters look like K&N filters but let through a lot of dirt/dust. If you believe all the advertising I thought the K&N filter was supposed to be the best of the best? Is this not the case and what we’re the problems with them and who makes the new filters? Ryco??
The K&N filters are all hype, as a mechanic I have seen far too many dusted engines from them. To get more air through them they need coarser material than a traditional filter which means less restriction allowing more fine particles through.
,,, could be the wrong oil . I saw an engine ruined from just that . Wife's Jeep has 230 thou on it, half with a K and N, doesn't use any oil betwixt changes ; however it is driven moderately .
For starters why would they when the pushrod motor is 99% of v8 sales for GM and also it is a much cheaper engine then the DOHC unit. The DOHC is also bespoke for the mid engined corvette Z06 and the C8R and I'm sure some idiot will come on and say otherwise but it has never been fitted to the Camaro and never will be.
@@carisi2k11 That engine is pretty exotic, however the GM Northstar V8 was not. It was a 4.6L 32-valve engine, the same as the Ford 4.6L modular which became the Coyote (now 5.0-5.2L). Should it really be Ford's problem that GM couldn't make their equivalent small DOHC engine good enough to keep a permanent place in the model range? Why not set the rules as strictly 32-valve DOHC only and give the KRE the tall order of developing the Northstar into a racing engine from scratch, just as other teams like Nissan and Volvo had to do? Having two similar 5.0L 32-valve engines would greatly simplify a lot of this parity mess. Why didn't Supercars say the 5.0L Coyote 32-valve will be the basic layout, so KRE go and get some old Northstar blocks and make the Northstar as similar to a Coyote as you can -- allowing the GM cars to have a larger capacity pushrod engine gives the impression of pro-GM bias.
I will make this simple for you GM's sale of new engines are based on the LS/LT platform which the camaro sells with brand new and that is a very realiable engine that can be built right way to make over 1800HP where as the Ford comes with a DOHC V8 factory.
The engines have different restricators as they 2 very different engines. where as the old engines could of been have had the same restricators has they where pretty identical blocks. The new engines are loosely based on the road version for the mustang is a 5.4l coyote based engine and the camaro is the 5.7 engine based of the ls1 so what they have to do with the engine builders is make sure that has the same power and torque not restricators
Wow so you only have 2 engines per car for a year. Do you always get the second engine back before the next round? If you blow one engine you only have one left. Strange it’s not more
I agree I think what it is that the engine is coming with a custom dry sump setup with a custom design and possibly the heads have a custom flow that supercars dictated for a certain torque and HP curve that closely matches a DOHC . I say that because he did say 70K for it all ready to go.
@@bremCZ It was alright in Group A! The solution then was for the manufacturer to build and design a better car, like the R32 GT-R. (Albeit some people in admin kept fiddling with race weights, instead of leaving the classing as it was...) Then it was up to Ford and Holden to build their own turbocharged electronically controlled AWD car (which they didn't bother to do for whatever reason, but at least the ball was in their court). I reckon the WRX STi and Lancer Evolution could have been good Group A touring cars going into the 90's, being in the 2000cc supercharged weight bracket like the Sierra and HR31 Skyline. The AWD Escort Cosworth could have been OK too, though I don't think the AWD system was as advanced as on the Lancer.
@@TassieLorenzo That is precisely what killed Group A. If they hadn't imposed restrictions then everyone would have been forced to run a Skyline or lose.
Thank you for taking the time to explain the engines Brad. Your videos are really informative and very interesting.
Just binge watched the old episodes and learned more about Supercars in that time than I did in the last 3 yrs ! You’re a natural at this Brad !
Brad is the hero the Supercars community didn't know it needed
bloody hell I wasn't expecting such big savings in costs for the engines, that is a massive difference.
This was great! An actual win for Gen3 for once! It’s amazing how not having to build parts prom scratch as needed saves on cost!

Great work again Brad - keeping it simply and real!
Thanx Brad for showing us all these little details about the new gen cars we have today
Outstanding vid, must be many dry teeth out there after everyone sucked in air hearing about the costs of the old engine rebuild costs.
Great work that u have done over the season
Always enjoy watching you videos Brad, educational and informative.
Love your explanations 👍
Excellent.
Thanks Brad.
Like a Scaifie explanation but without the Ritalin😎👍
Literally laughed out loud
Hi Brad - thank you for sharing this information and your knowledge - Regards
Great insight
Great information 👍thanks for doing these videos Brad!
Very interesting facts
Question? Putting aside tyres and brakes, I'm amazed how quickly these cars warm up after sitting around forever on the grid, with only one warm up lap. Especially on short circuits. Not only motor, but clutch, gearbox, diff, etc? And all the oils warming up?
The engine oil is preheated with an electric heater, as is the transaxle.
thanks Brad 👍
Most excellent 👍
Brilliant.
The aluminum block would compensate for any power loss with the cheaper heads. Big gains to be had .
What if you are unlucky enough to lose both engine & have to send them away for rebuilding ?
Years ago I asked why Supercars didn't go to 'crate' engines. A lot of the arguments were about losing the skill sets of engine builders and so forth.
So if there are engine failures and the build is to spec and fully outsourced, what happens?

I've seen a video on UA-cam that tested various air filters and the K&N filters let more air in as well as more dust.
Ryco A5000R
Down a peg brad, motors are not the issue.
Can we see the Chev restrictor? We have seen the Coyote one often but no one will show or explain the Chev one if it has one.
they peobaly couldn't them selfs as it would be locked into the engine we would need to hope KRE/Supercars show us that
Try the Supercars engine build videos that Larko did... Shows dyno runs etc...
Brad my question that noone seems to want to answer is why are the gm's running the pushrod engine and not their dohc engine?
For starters why would they when the pushrod motor is 99% of v8 sales for GM and also it is a much cheaper engine then the DOHC unit. The DOHC is also bespoke for the mid engined corvette Z06 and the C8R and I'm sure some idiot will come on and say otherwise but it has never been fitted to the Camaro and never will be.
Also it is a flat plane crank and not a cross plane like the Coyote and LS/LT motors.

KRE did all the engine development they wanted manufacturer relevance...

The intake on that engine does it have the same restrictor as the mustang?

How does a N/A 5.7L alloy blocked LS cost $70K 😮
Trying to work that out myself. Seems excessive for what it is

900hp 410 sprint car engine use to cost us $60k.....&, KRE build both
$$$$$$😮
Crate engines are cheaper! Until SC decided to fiddle with them and make two custom engines anyway.
Parity is a major problem imho
Always has been, always will be.
Yep, Fords are always whingeing, and always get their way.
