Who in SE QUEENSLAND is prepared to have their cars dynod after they have put on 2000or more km , hopefully if we can get 5 or 6 cars dynod we will get real answers as to the OZ cars real power out puts .

177KW ?? 170KW??? 167KW??? I AM CONFUSED.

ALSO THIS WILL TELL US IF ANY OF THE 6 PORTS ARE NOT FUNCTIONING CORRECTLY.

A couple of workshops around town have customers with rx-8's with turbo conversions planned. Mazfix was definitely one of them. Maybe worth a call to see if they've run one up yet?

I don't know what you are going to achieve. I certainly wouldn't let me car be tested until it had at least 10,000km on the clock, and an assurance that the process of dyno testing wouldn't void the warranty (you see, I haven't seen a clear exposition of what dyno testing involves).

If I were Mazda, it would take more than some "uncontrolled" dyno tests to convince me that I had a problem. I qualify my remarks by saying I'm not an automotive engineer, but I am a professional analytical chemist with decades of experience in experimental design and the performance of standard tests. Firstly, I would want the tests to be conducted in an independent testing station, preferably NATA-certified, and conducted by professionals who are prepared to put their names to evidentiary quality documentation which says the tests were conducted under internationally-recognised protocols. There would need to be mention of any variation between these protocols and test procedures used internally by Mazda, and if there is a variation, re-testing according to Mazda methods. There would also need to be immaculate documentation concerning the preparation of the vehicles prior to the dyno tests (statements such as "I gave it a bloody good burn up the M1, and a few decent buzzes up to Mt Tambourine" would not qualify).

Look at it from Mazda's point of view: there is the potential for litigation, there is the PR fallout, there are the recall, reimbursement and warranty issues. I would want every i dotted and every T crossed. Certainly, go ahead with your tests, but be aware that they may carry little weight in the long run.

I think the point of Lock&Load's idea was just to confirm that we are getting Euro3 spec cars. There's no need to build a case against Mazda Aust. because they've probably been honest from day 1.

Since there's a very good chance that nothing is amiss down under, I don't think it warrants going to the effort of a scientific test. I agree though, that IF something was found to be amiss, it would be better to approach Mazda Aust. with proof not a couple of printouts, but we're a long way from that.

The second my car reaches 500km, im going to thrash the arse off it...

A good mate of mine had 26 km's on the clock after his full rebuild (bearings and all) when a VL turbo raced passed him and waived. His car went well under 14psi of boost while he passed him. In theory, the engines are designed to rev hard.
