I have just noticed that the inside of my tail pipes are white now after n20 and running race gas in it....do i have anything to worry about???

 

I wouldnt worry, its usually just when you ran it really lean it melted a bit of the piston skirting which turns white when it burns.
































































I have no clue, but i thought id scare the hell out of you

 

LMAO

 

some fuels like the rocket brand that i run have a chemical in them that do that. alot of people have tried to tell me i was lean also

 

id slap it on a dyno. just to make sure. dont wanna be running lean

 

Thats common when running some types of race fuel - its usually not the best for your O2 sensors but it wont necessarily kill them right off the bat either...

 

It is just the fuel, when I put the 110 fuel in my bike the exhaust tip of it turns completely white as well.

 

dont worry about it unless it keeps happening a lot

 

The white is more than likely the cause of the lead they put in the race gas. the residue plugs cat's and kills O2's so dont use it too much. I would run unleaded race gas if you have either.

 

The odds are it's not a lean condition causing it, unless you drive to store and work everyday juicing the snot out of ur car. Most likely a by product of the gasoline you used. I can't say I've ever seen a exhaust turn white from running lean a couple times at the track, not without seeing some parts of ur engine chillin out at the bottom of ur oil pan...

 

I don't run race gas... but my friends Supra always has white residue on the pipe after making a pass with 110. It's not a lean sign... it's just the gas.
