Because 800hp and 10.3 sec means ridiculous amounts of g's. It's a common problem mate do a search. In mine with 450hp anything less than 6l it surges.

Did you read this: "Up until 1 month ago, it had standard sump with the oil just filled to the top line on the dipstick, as you would with any car. When we changed the diff ratios, we installed a 9L sump and again filled it to the top line of the dipstick. WE HAVE NEVER OVER FILLED THE ENGINE WITH OIL!" - from Trent @ Mercury Motorsport.

Yea I don't think it's really a problem in a straight line mate, you mite have pump issues or running a oil that's too thin.

Yeah I did read that Trent thanx. Dean do u have an a/m oil pressure gauge ? It might surprise u :)

Yea I do mate, $900 worth of Defi's sitting on my dash, 8k limiter launches on 265 semi slicks........... No surge!

Just filled to the line, I fill it to the hump when i change my oil for trackdays. But general cruising round filled to the line, it takes around 6L because of the oil filter relocation kit and oil cooler, which is emptyed out each oil change.

    • Does that price include the rack time to straighten the frame and body and replacement of parts and paint, as well as the noise and emmisions testing  The last engineering certificate I had done, albeit about 15 years ago, was around $1000 for a few inspections and the certificate 
    • 😂 thanks guys. The diagram i had did not have the breather on it at all. Much appreciated.  
    • Geez, engineers fees have definitely gone up. Mine back 2007 cost me all of $300. Mind you, I had to go back to him a few times to get him to write the correct things on the report after he'd inspected it. Things like wrong exhaust size, wrong wheel sizes, etc etc.
    • Can we see a scan of the original quote? The problem with engineers (and by this, I mean, all engineers across all engineering industries) is that there are "engineers" and there are "engineers" (you'll have to imagine the two different vocal emphases on those two versions of the same word. Engineering is a mindset - your farm kid who spent his life rebuilding the tractor will likely make a good engineer. The farm kid who spent his life taking photos of butterflies.. perhaps not. But on top of that mindset, the modern engineer has to learn how to write so that there is absolutely no way of being misunderstood. Proposals/budget estimates/quotations are one place where this is absolutely vital. You have to delineate your scope of supply with extremely hard boundaries, and anywhere where there is any possibility of not being able to have such a hard boundary, you need to write language that will cover you from scope creep, cost overruns, the inevitable interference of the client or their "engineer", etc etc. Now, if your clients are the BHPs and the Rio Tintos of the world, and similar, then you get good at this. If you are an automotive engineer, pitching work to the great unwashed masses, your skills in this area might not be well developed, because you're only dealing with knuckle draggers trying to get a big block legal in a Torana. And when I say "might not"....I'd suggest there's a better than even chance that any such skills might be completely absent. So, we might be able to look at your quote and see what the opportunities are for rebuttal.
