Hence the need to check the calibration of the machine with a test bottle. If it was reading .1 higher with the test bottle then allowance could be made when testing engines. Like ou say tho, if this equipment is the best they are going to get, the prudent thing to do would be to allow a bit more margine for error when building the engine. An interesting read on the test procedure here for those that havent seen it done. cms.scca.com/documents/Whistler%20Procedures%20Manual.pdf |

I have to disagree with the comments suggesting it is better to run below the limit to avoid situations like this. If the rule says you can run 10.1 then you should be allowed to run 10.1
Firstly, what is the point of having the rule if we can't build our cars to it? Another example is tires, they have to have at least a 55 duro rating, mine were tested, one came up at 56 and it was recommended I think about changing them because they are close to the limit, I think it's silly to say here is the rule, don't go near the limit.
To be clear I don't have a top car built to the rules, and I run those tires because they came with the car and I'm not going to buy new ones because they are 'close'.
2nd, running below the limit wont always avoid mistakes like this, I can't compare it directly to this situation, because I don't know exactly how the cars were tested, but a couple of years back I had an engine tested at the track before the Waikato superstock champs, my reading was over, so, I was stood down until I could prove it was legal, the next week the heads were stripped and all the rest, the actual compression ratio in my engine was as low as 8.1, varying slightly cylinder to cylinder , but still well below the 10.1 rule. That is the end of that story. Point being, the rules are there, they should not be exceeded, I don't think it is necessary to run well below the limit, and even doing so can't guarantee mistakes wont me made.

Yes Stanaway went well last night at Rotorua .
Apparently it was proven that the engine WAS NOT illegal , so what was the end result for Stanaway .
Was he compensated for the stuff up.
Sad really that he was denied a shot at the NZ title through no fault of his own.

So sad to see especially after qualifying among 170+ cars! |

Also Got told by Douglas that the engine builder skimmed it back just a little bit more so now he's running less than he is allowed to ...which sucks...
anyway was put back together again and tested with same machine..... 10:4 again?!
Time for a new machine maybe?

You cant just 'skim back' compression in an engine.
I think the directors meeting is this week, so I guess we'll hear the actual story after that. Still a lot of hearsay around.

Yes more like shimmed to lower the ratio a tad or two.

You can skim the piston crowns which will lower the compression ratio tho, maybe wat was ment by skimming

sorry about my terms and words i know nothing about engine building or the like.... openly admit that just using words hat were told to me  Still sucks! |
