Thanks for all the great responses people............... Even though no one really answered my original questions about having any experience with Edelbrock or Holley injection kits. I'm still happy that it drummed up a little discussion. What really disappointed me was no one commented on the sex of my Javelin versus their car................ How the heck do you guys think these things reproduced in the first place??? They went extinct, you know, because their food chain was disrupted by the gasoline crisis of the seventies........no more high octane leaded fuel!!!! Without food they couldn't reproduce!!!! Ha ha Have a good one every one, Armand That's really good news -- I'd never heard of anyone running " open-loop *FI successfully. until the '80s, all efi was open loop. my family had two '71 saab 99s, one with carbs and one with the original bosch jetronic first used on the '66 vw squareback and afaik based on bendix patents [remember the '57 rambler rebel?] bosch bought. the engines were identical save for induction. the efi car got almost 10% more power, better mileage, better driveability, and ran on lower octane than the carb car. the only problem we ever had with it was the engine temp sensor; when that failed the idle speed would 'hunt' up and down in cold weather until it warmed up. other operation was not affected. " Even carbs are not exactly "open loop"; fuel flow is proportional to " airflow plus and minus. not linearly proportional or carbs would be a lot simpler. iirc vac in a venturi - which is what pulls the fuel through the jet - is proportional to the square of the air velocity. ________________________________________________________________________ _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
