superchager with a blow thought carb question
Okay over the weekend at the track I started helping a guy pitted near me with a 67 Mustang with a 351W with a supercharger and a Demon carb.
When he goes WOT it will run good for a few sec's and then die out and if backs off the trottle it will stumble of a little bit and then start working better at about 1/2 throttle.
when he drives it on the street there is no issues until he tries to go WOT
We changed the fuel line at the track to a big 1/2 inch line.
We also tried different fuel pressure setting 6psi on idle goes up to 9 when revved up on low boost in the pits
we also tried idle 9psi and boost 12 psi
it has a MSD box with boost controller
What info do you need? This is a good older guy that I want to help out.
