gretchen/jason Posted February 18, 2007 Share Posted February 18, 2007 I can atest to the need to tune a engine for altitude . I lived in Lubbock Tx for about 2 years tuned and built my z car and had a blast atthe drag stirp atonly 2,000 ft above sea level . Ive since moved to Colorado springs about 6,000 ft above sea level and man what a loss of power to my ride but some proper carb jetting and such and my z came alive again . i was one of those guys who always thought bigger was better man was i wrong .

mamba_888 Posted February 26, 2007 Share Posted February 26, 2007 Yup, and we get hit three way's... less engine power, less molecules for the prop to work with, and less molecules for the wings to work with. All this makes for a huge performance difference with as little as a 10 degree shift. BTW, Congrats on your PP Cert.!!!! P.S. I'm with Juday... THIS is what EFI is all about. Don't forget the relative humidity or amount of water in the air! I always check, double check and triple check my density altitude when I fly out of Lake Tahoe!!! Not to mention carburetor icing in the SUMMER !!! Quote Link to comment Share on other sites More sharing options...
