AK-Z 10 Posted June 24, 2010 This question isn't on my datsun, but might as well ask. I took my turbo off my other car, and the turbine wheel appears orange. Does this I'm running lean, rich, or what? thanks. Quote Share this post Link to post Share on other sites
neotech84 10 Posted June 24, 2010 Black is usually rich and white is lean. I think you are fine on the rust orange or maybe slightly lean. It should clean up with come carb cleaner. Quote Share this post Link to post Share on other sites
AK-Z 10 Posted June 24, 2010 (edited) Sorry, this is on my genesis. like 9K miles on it. So, its pretty new. Its pretty orange. I've tuned it a bit. I've swapped it out for a WRX one, because the turbine fin angle on it are a bit more aggressive. Sorry, bit blurry.

AK-Z 10 Posted June 24, 2010 Oh. and I thought it was black = rich. thats why when I run it rich my tail pipes get all sooty Quote Share this post Link to post Share on other sites
kiwi303 29 Posted June 26, 2010 Try looking at spark plug colour charts, I wouldn't be surprised to find a close correlation between spark and turbine colours for rich/lean etc. Quote Share this post Link to post Share on other sites
AK-Z 10 Posted June 27, 2010 (edited) found out what it was. I put octane booster in the tank, because of the craptastic "premium" grade gas that they have up here (90 oct is considered premium up here). Edited June 27, 2010 by AK-Z Quote Share this post Link to post Share on other sites
