STEWARDS REPORT RE PENSKE ENGINE

The latter is the normal thing to do but the former gives the actual camshaft lift measurement at the valve head. Camshaft lift is used to degree the camshaft which is a fancy name for splitting the lift each side of TDC. Splitting the lift retarded or advanced either side of TDC has advantages depending on the track configuration, Bathurst and Winton would ideally have the camshaft timed to do different things if the regs allow splitting the overlap each side of TDC.

I would have expected them to measure the actual valve lift as that is the most important value regarding engine power. If the engine uses any kind of rocker arrangement the pivot ratio could be altered to increase the valve lift with the same camshaft BCD to lobe dimension.
On this subject, I seem to recall reading that the out of tolerance value was 0.0015" which is 7/10ths of naff all. If the Dial Test Indicator isn't set in exactly in line with the valve movement (so at a very slight angle) this could easily explain the discrepancy. (I say this based on the experience of this having been done many years ago here in the UK...)

Wierd that DJRTP have accepted this with no appeal if there is apparent doubt....

Not really - Supercars/Cams have got them over a barrel.

They know full well DJRTP will pay any trivial fine at this late stage in the series, as Bathurst and the championship are too valuable to risk through an appeal process; and they also know RP isn't short of a bob or two.

It simply looks like leverage is being applied against a soft target, for both financial gain, and 'parity' control to appease their perceived target audience.

You are one of their target audience like it or not. Can I please have answers to my previous questions? Thanks.

So the terrible bullying and abuse that poor, poor Scott had to undergo was DJ Walky saying "it's so unfair they caught you guys cheating", after Scott made comments about how he was happy he never signed with Walkinshaw in 2016.

Scott will continue to get **** from all and sundry because he has shown himself to be absolutely soft. If you run your own mouth, then run to the principal when someone answers back, you are gonna get a wedgie.

Funny how Scott seems to have PR skills closer to Ambrose than Lowndes these days.

Good to see Supercars are looking into the social media taunts aimed at Scotty:

The one from Pye was just plain stupid.

It's not cheating unless it was a deliberate action and I don't think that has been established.

Indeed not.

But this issue shows up some true personality traits, many of which are undesirable.

[bluesport]

What caused the extra valve lift was a worn or damaged camshaft bearing at rear of the engine that allowed the camshaft to lift minutely and give the extra lift to the rockers, there was no problem with the front bearing so the front two cylinders were not affected.

DJ Walky was simply cracking wise, and in true Johnson form, Scott cried about it.

The insinuation, and the subsequent trolling, all come from the same source.

That's merely your view as a seasoned online troll!

I strongly suggest everyone click on that link.

Your standard bearer for probity is the Walkinshaw family?

A fair bit of sense here. Pretty terrible how Steven Johnson decided to attack Walkinshaw when it appears Walkinshaw was merely reacting to Scott badmouthing him at Sandown and saying he was glad he didn’t sign for HRT in 2016...

I wonder if he will apologise?

Scotty Mc voted the most popular driver for the 3rd year running.......Ch10.

That's interesting, could you post the link too where you found that information please? I'm intrigued to know how a worn or damaged cam bearing could increase the overall valve lift.

Also interesting the best funded team in pit lane arrived at the biggest race of the year, a race they would do anything to win with an old worn out engine fitted to their number 1 car? only removing it after setting poll as a precaution "their word" as they had doubts it would last the race.

Let's stop with the old worn out boat anchor story.

[JAFA851]

Interesting to note that, since Bathurst, the team that had totally dominated everything up until Bathurst, has not had a single race win or pole position since. So after they took the parts off the car that didn't comply, they can't smoke everybody anymore?

On another note, on the Supercars website they still have this illegal car as on pole at Bathurst too. Come on Supercars, at least apply the pathetically weak "penalty" you gave them.

I think T8 took out the sandbags out of the trunk they put in when they decided to concentrate on Bathurst win. Since then you see the true potential of T8

.

Perhaps all the extra parity mods and downforce increases Holden were given did not suit Bathurst but did the other circuits since? Not rocket science.

Are you sure the front 2 cylinders were not affected?

Then I wonder if the hundreads of people who abused him will apologise. Whatever you think of Walkinshaw it’s pretty poor form for someone to call him out like that and only tell the side of the story that suited him when clearly the full story, if anything, makes Scotty Mac appear to have behaved poorly and triggered the chain of events...

Regardless of the engine issue, it was a breach. Other engines have been pulled and found they were not. Take your medicine and move on. But let’s never forget that DJR Team Penske committed one of the worst acts I’ve ever seen in 40 years of watching the Bathurst 1000 with their team order on Coulthard that utterly destroyed the races of many of the teams down pit lane. For that alone I can fully understand the anger and frustration that is clearly present in pit lane this weekend towards them.
