blue flames from my exhaust, WTF
I am confused . Can someone smart explain me how come my car is shooting blue flames from my exhaust when reving high on agresive driving?
Here is the catch, the flames are not instantaneous they are long and they last. My lady(Evo9grl) was trying to catch up with me and she swears up and down that my car was putting blue(not orange or yellow) flames.. can someone explain me that? Oh yeah, this happened at midnight also so the flames are much better visible.
I just got retune by Al, and I am running a number #10 nozzle with methanol and a lot a lot of boost. Any thoughts? are blue flames indication of a much lesser exhaust gases temp or what?
Thanks!!

flames from your exhaust during acceleration is strange. normally flames occur on decel due to too much fuel on the low load portion of the map.
im guessing that you might have a slight misfire, or that the methanol isnt completely burned inside the combustion chamber and continues out your exhaust pipe. i'd try gapping your plugs lower if they arent already done so or upgrading your ignition.

On a side note, did you notice a power difference getting tuned on the #10 nozzle over the #7 nozzle? Are you running more boost than before?

The car drives fine, faster than ever but yes indeed , I think I am putting too much methanol and perhaps I am running a bit rich.
have you guys seen the boot I am running on stock turbo? absolutely no knock.

wow i didnt think the defi gauge would go over 30 psi. it hasnt broken? also the volumetric efficency of the stocker is around 26 pounds. so ya you have no knock cause you have enough(or in your case more then enough)fuel and the right amount of timing. after 26psi you are just blowing hot air. it makes some power but not as much as a turbo in its efficency range
