I have found myself in a situation where I need to find just under .2 seconds with my bracket car. It used to be the footbrake class we have around here was just one class with all cars run and a fast ET limit. Now we have sportsman and pro classes with pro class using a 13.99 ET cutoff on the slow end. After a new converter install last week, I was running low 14.0s. I cannot make an engine mods, and I also want to stay away from weight reduction if at all possible. Since I run brackets, I never really messed around with fuel pressure. However, I am trying to squeak out as much as possible. Currently I am running 50PSI with a Holley regulator. When I had my car dynoed, the A/F ratio was just about 12.0 averaged out over 4000-5500 RPMs. Has anybody experimented with adjusting the fuel pressure and how much did it change your ET? Thanks in advance!!!!
PS-Please don't suggest weight reduction and/or engine mods. I don't have time for engine mods, and I like to keep my car looking streetable even though it is a trailer car.
