I have to think that there will be other guys there in the same boat. Doesn't the PCA have a tech there just for that reason??
Oh yah right, I forgot the members with all the $$$ are driving new cars and the techs will be there to assist in the selection of wine. |

I would have liked to go to the Parade this year but the AX turned me off on the idea. I skier's parking lot at 9300 feet doesn't do much for me.
I have no clue how to jet for that to boot. EFI & turbo cars will rule....unless the course is as tight as rumor has it......then a 914 has a chance. |

I'll keep a eye out for you, really looking forward to having Parade in my backyard.
Maybe Brant or someone with some real knowledge will chime in as I can't help you much with the carbs, running rich won't kill ya. 10% ethanol is true, but you can still find places that sell the good stuff in the summer. Not sure up in Keystone though. Ferg (IMG:style_emoticons/default/beerchug.gif) |

You can adjust your mixture when you get here. The fact is, you'll start feeling the difference in altitude at 4000 feet. If you can't adjust your own carbs now, you should get some practice in beforehand.

I still don't understand why they would host a parade and AX at 9,300 ft! IMHO, it would have been much better to host the parade at a much lower altitude, and make the 9,300 ft parking lot a day trip.
I wonder how many of the old farts (i.e.my age) will keel over after a few days in 9,300 air? Eric Read |

I have been over 11000ft.. Just change the Air correctors on the mains 2 sizes up (example: running 1.75 air now, go to 1.95)
This will allow it to not foul the plugs so easy. It may still run doggy.. Art Thraen @ ACE www.aircooledengineering.com |

I know that the cars acan be made to run Ok at 10,000 ft altitude. But still, doesn't an autocross at that altitude only really appeal to tuners?

I don't get the complaint about running an AX at 9600'. It's not that big a deal.
I live at 5k and drive a carb'd 914 all the time. It routinely goes up into the mountains in the summer without mucking around with the carbs. 10k is pretty average. My car tuned for 5k runs OK at that altitude. Not perfect, but it's not bad. The summer before last I drove it up to Mt Evans summit at 14k feet. Ran like a dog, but for an afternoon trip at that altitude, no big deal. BTW, thanks Art for the altitude tuning advice! What setup would you recommend for a pair of Weber IDF 40's on a 2056 Type IV at 5k feet of altitude? Main/vent/air/idle/etc...? |

If you are driving through Grand Junction, there is a Master 914 Mechanic there, Allen Johnson, He could set you up right before you climbed the big hill, maybe overkill, but if you bought the supplies before hand, it would be a good place it install tune ect.

Here is one reason for the location choice - this is where the concour will be (right off my deck!) As well the parking lot for the AX is giant (several acres). and backs right up to the new base area at the resort.
Why would you want to be in just another city location, with the logistical hassles? When in Colorado, dont you want to actually experience Colorado? Attached image(s)
