Well the work for me is fun, and doesn't cost me much. The question I had was about efficiency. If there are numbers to be gained with the spray under the rotors it would be worth it to me. The question of spaying meth/nitrous on the rotors always comes up, but never really gets answered. Does it affect the life of the rotors? I have heard about the same from both camps- yes, from the factory "charger" guy... and no, from everyone else. Just curious.

 

I believe spraying before the compressor will net better HP results. There was fear of the coating on the rotors corroding from meth a long time ago but after spraying with the 112 for a long while those rotors were just fine.

 

Good to know. As for expense of under the blower. Itd be free.99 for me just the time to do it

 

I sprayed meth on my KB right in the spacer between the blower and lower manifold where the air comes out of the blower before it goes though the intercooler where it would be the hottest and also in the air tube pre-throttle body and couldn't tell any difference in power or cooling. Both were M15 nozzles.

 

KB- pics of you meth set up??

 

There is the pre-TB nozzle placement (red tube)



There is the nozzle at the outlet of the compressor.




And a vid of it spraying.
