went to the track this weekend, first time ever racing, and my first ever run was a 13.3!! My truck was way over 7,000 pounds, 500 pounds in the toolbox, 18" wheels, 33" tires, and one of my friends sitting in the passenger seat. Also, I ran that 13.3 with the truck blowing the pressure releif valve and going into limp mode about 75 feet from the 1/4 mile mark!!!
I ran 12 times, blew the PRV every run, 1.8x was my best 60 foot time. 13.2 at 103.9 mph. Sooo the 104mph trap speed shows im making power, just need to launch better. With the truck not going into limp mode, and a 1.7x 60 foot time I will hopefully be in the 12's. Engine is bone stock other than a BD
turbo and AFE intake. Transmission is a Suncoast IV, exhaust is MBRP
. I did not run stacked, this is with Bobo's tune alone!! Also, I had no smoke after launch. The BD
flows a lot of air and needs more fuel up to. I need to shim the PRV some more. When I shim it more, I COULD be in the 12's. We'll see in 2 weeks when I go back. Ill also try to lighten the truck up a bit.
