My roomate owns an 3g RX7 and he just told me that some of those guys add pure alcohol (about a gallon) to a tank of gas and it helps their cars pass inspections. RX7's run pig rich

Im not having any problems passing emissions; I was just wondering if any of you had heard about this and if it has any truth to it or if it's complete bullshit. And an explanation on why fuel+alcohol would burn cleaner emissions.

 

um arent rx7s rotory engines and i would think if anything alcohol would make ur engine run hotter= more emissions unsteady idel too im not sure on any of this

 

Yes, rx7's are rotary powered engines, but the alcohol would cool the air and allow them to run more boost because it would also raise the octane of the fuel.

Some of them actually run alcohol injection, which does the stuff mentioned above, and I believe all FD's water injected, which helps cools the temperature of the intake air.

 

yes you can use alcohol in to pass emission(but its not 100% sure you'll pass with alcohol)

 

But why?

I guess I'm looking for a more chemistry related answer...

Where can I get it aswell

 

Adding alchohol MIGHT reduce your NO numbers by a little bit but don't expect to get any major results. It's almost just like adding octane booster to your gas. It will not have any effect on your hc or co readings though.
