We had a blast at Pomona. Good times with friends and family. I got to make two passes, should've been three but I blew a heater hose in the burnout box and had to get pushed off the track
haha. Talk about embarrassing in front of almost full grand stands
Best was a 12.17 @114mph. The car was starving for fuel (sputtering on the big end at the top of 3rd gear and 4th gear) so I made a jet change and it actually hurt it more. Fuel pump can't keep up with demand....
I was really thinking it would run high 11s considering the weight of the car, over 3600lbs without driver, and the 3.55 gears so I'm close. I am going to convert the car to 1/2 hard fuel line with a 1/2" pickup and an Edelbrock mechanical pump.
After the track I conducted a fuel pump volume test after talking to some drag racing buddies. I removed the fuel line on the secondary float bowl and plugged it into a rubber hose draining into plastic jug. My mechanical pump only pumped 8-9oz of fuel in 12 seconds. Turning on my electric pump, which I had on during the runs at the track, I saw 29oz of fuel in 12 seconds which is about .2 gallons. Probably very close to the amount of fuel I need in a 1/4 mile... too close for comfort!
Not that the car is a drag car but I want to be prepared next time. Some things can only be discovered on the track!
After I install my new fuel lines and pump, I will install the Tarantua TM2-O intake and bring it to the dyno to make sure we have enough fuel!
