so answer number one is correct Area divided by Radius = A/R ratio
A/R = A/R ratio
just like you said.

 

instead of just reading a book that has a **** load of outdated information that is over-explained to the point of easy misunderstanding I actually applied the info that was given to me to a real world situation. I measured the indicated areas and applied the math and got the correct answer without any hokus pokus or mumbo jumbo that doesn't mean anything. The HKS tech and Greddy tech reps are engineers who deal directly with Garrett Japan and Mitsubishi. I was talking to guys who actually design turbos and not some guy who took a bunch of info and put it into his own words.

Give us the equation that will show the correct way to determine AR instead a bunch of quoted CRAP. I chose the HKS tech reps answer because it seemed to be more logical. I also did not have the means to measure the area of a compressor housing.


I was gonna edit this but decided to leave it here instead.... and since I chose to use the HKS answer it would be aspect ratio and not area radius since I used a RATIO of the smallest diameter of the compressor outlet to the radius of the backplate.

You know it took me 5 minutes to type up that reply....you can at least appreciate the effort. I didn't type it up just for you though. It was also meant for the other people that have no idea what a A/R ratio is. My only regret is not having a scanner and my own server space, so that I can Illustrate my points as well.

Even If I could Illustrate it to people I wouldn't, because I still have a little trouble with the concept, een with the pictures right in front of me. And since when did this method of measuring or describing A/R ratio's become outdated? true the book was published in 1997 but IMO that doesn't make it outdated. No offense to any of the turbo guru's in this forum, but this book has taught me more about FI than anything else.

 

no problemo dude.... I'm about to go get wasted so I'll make sure I make a toast to you when I get to the bar! Never argue with a JDM woman! I lost the the argument on purpose and she still wants to argue more! Women! Can't live w/o 'em and can't turbo charge 'em!!
