i ran 2 750 eddy's on my blown 383 worked great. only problem was at the end of the 1/4 at 130mph it blows fuel all over the windsheild. i think if you read it says those carbs are not designed to be outside of the hood. my buddy has eddys on his 440 and it works youtube

John, I have not seen any vacume at WOT on the engines I've dyno tested between the carbs and the blower rotors ![](/ubbthreads/images/graemlins/shruggy.gif) , same thing below the blower when at part throttle going to full throttle before boost is made ![](/ubbthreads/images/graemlins/shruggy.gif) It would (vacume signal)read vacume at part throttle in the blower intake and then go to zero and then start making boost ![](/ubbthreads/images/graemlins/shruggy.gif) This was with two 650 Holleys, two 1050 Dominators and two 750 carters, I have not dyno tested a roots blown motor with a single carb so I don't know if they wll make vacume under the carb at the upper RPM or not ![](/ubbthreads/images/graemlins/1343795-scratchchin.gif)

We did (4-71, single Holley 900), the answer is (in our app anyways) no vac. below the carb.

I had a pair of 750 Mighty Demon boost referenced carbs on mine until I went with EFI. They worked great, motor was 440 with a 8-71. I had a pair of edelbrocks on there before that and they were always a touch lean under full boost. Matter of fact just reminded me I have to get rid of them ![](/ubbthreads/images/graemlins/1343795-scratchchin.gif)
