foggy visor

open the visor , or try not breathing

just close it on your thumb, it gives you a little crack that will allow enough air in to keep it from fogging

We had the same problem during our first race at CMP.  Our solution was a lemons-style tracheotomy for all of our drivers using rubber vacuum lines.  There were enough Rx7s at the track that finding "extra" vacuum lines shouldn't have been a problem.  The nearby "Team Quaalude" seemed to have plenty of access to "anesthetics".  What could go wrong?

We were too chicken to try it out though and ended up just cracking the visor a bit.  Oh well, maybe next time.

(in all seriousness though I'm wondering if there is a device so the driver is always breathing fresh air and not stale air from inside the helmet?  that would seem to eliminate the visor fog.)

i heard pledge is supposed to work.  I haven't tried it yet, but haven't had a visor problem.  The biggest problem I've had is wearing a blaclava and it fogging my glasses.  The solution so far is to not wear the balaclava.

It's a product from rain-x called fog-x.  There are other "anti-fog" sprays too.  Google them or check on amazon, pep boys, autozone, etc.

I agree with wrappedinbacon - my visor always fogs when I'm still.  Unfortunately, this means my visor fogs during fueling, which is when track workers are most strict about having the visors all the way down (as they should be, IMHO).  Happily my visor never fogs while I'm driving, unless there is a full coarse yellow and folks are driving hella slow. 

Until the last race I'd been driving with my visor completely up... which defeats the purpose of having a fire retardant helmet.  Cracking the visor also defeats the purpose of all of that lovely SFI fanciness.  After watching YouTube footage of recent crashes, including the Gremlin accident I filmed, I decided that foregoing any easy safety measure was stupid.

I want to get fast, not dead.

You make it sound like it was our fault!!  I guess "escort flip" could lead you to a couple different crashes.  Infamy is better than nofamy I guess.  Carry on.

I wanna get a HANS or Dfender now.  I doubt the Gremlin will do any acrobatics during an accident, but as you said, it's stupid to forego it.

I can tell you from (sad) experience, Pledge does NOT work. Pledge = pleh.
Since then, I've had the track worker at the start even remind me to crack the visor open a wee bit. Works like a charm. Now, breathing in brake fluid fumes is another matter.....
