Fuel System and Performance Benchmarks
At 8:45 in
He Turned His Grandpas OBS Chevy Into A Turbo LS 4x4 Monster!
What happens here
The owner presents the fuel system setup in the truck's bed, featuring a fuel cell. He humorously displays a 12-pack of Michelob Ultra, jokingly calling it the 'big secret' to going fast. He elaborates on the necessity of the fuel cell, explaining that after witnessing several trucks with similar setups catch fire due to driveshaft failures igniting the stock plastic fuel tank, he installed the fuel cell primarily as a safety measure. He then details the truck's performance figures, recalling the previous nitrous setup (6-liter engine, large cam, 4L60, 150-shot plate kit) achieving consistent 7.35-second quarter-mile times at 92 mph. With the current turbo setup, the truck is now running 6.90s at 18 psi, aiming for low 1.40-second 60-foot times and an increased boost of 20-24 psi. He mentions not yet utilizing the transbrake, which remains a future adjustment.
