Blue flames

[supraguye]

Posted this in the supra chat thread, got some responses but not anything confirmed .... Just want to be sure I am not doing any damage to my car.

 

 

So .... after having my car been parked for 4 months .... respraying/minor body repair .... aftermarket suspension and brakes .... Blitz Intercooler installed ()

 

I went at it last night ... and according to the person driving behind me ... it was spitting blue flames.

 

Now I have seen orange flames from many cars ... but blue flames? ... what could be the cause?
