Holley/Demon Carb stumble



So after loading the video up on my laptop, i decided to jet it up 2 more steps AKA the stock jet the proform came with.
felt much better but no Change in et or mph. However the first runs were at 8920 foot adj altitude. after my jetting up, the altitude when up to 9532. My last run of the day it was at 10,269 feet My mile per hour was down 1 to 1 and a half mile per hour all day long.85.2-86.1 The last race, were the air stayed the same at 7960 feet my mph was 97.xx all day long. it was in the 60 degrees all day and today it got up to 97 degrees were my camper was parked.

You're saying the MPH this weekend was 85-86 in 10,269 DA but it was 97 MPH in 7960 DA the previous race. I don't think it should have a swing that wide for 2000 feet of air change. If you meant 87 MPH thats totally in line with the DA change. You should try that other carb just to see where it stands.
