We bolted on a 4150 Quickfuel 950 to replace the Rupert 4500 1050 we had been running. We were actually trying to slow the car down a little because we were creeping up on the limits of our chassis cert.
The car ran the exact same ET and MPH with the 950 as it did with the 1050. The Quickfuel was spot on out of the box and only needed idle mixture and speed adjustments. I am happy with the Quickfuel carb
Where you able to jet the bigger carb rich enough to slow the MPH down in the 1/4 mile? If so did you do the same tuning on the smaller carb?
Which motor and heads was this on?
I'm thinking of switching from E85 to straight Methanol also
