2017 5.3 ProCharger times

Gorske · May 20, 2018

Well I finally made it to the track. I only got two passes before it started raining again...

Little back story first...….

Truck stock ran 15.21 @ 89.86(1/4) 9.70 @ 70.46(1/8) with a 2.13 60ft. with 93 4wd launch stalled up to 2500rpm and switched to 2wd after that launch.

Best 93 time with a tune, K&N drop in filter, Airaid MIT, and custom cat-back was 14.40 @ 94.78(1/4) 9.22 @ 75.31(1/8) with a 2.07 60ft. same type of run stalled up 2500rpm, 4wd launch, and switched out to 2wd after the launch with 6100rpm shift points.

Now to todays runs. First pass I screwed up and over powered the brakes and broke the beams but it gave me an idea what my mph would be 82.06mph in the 1/8 and 103.12mph in the 1/4 with launching it in 4wd stalled to 3200 rpm with it flashing to 3800 rpm and leaving it in 4wd the whole pass spun all 4 tires on the launch.

Second pass and last pass due to weather was 13.22 @ 102.44(1/4) 8.42 @ 81.37(1/8) with a 1.87 60ft. That was launching it in 4wd stalled to 2500rpm flashing to 3800rpm and leaving it in 4wd for the whole pass 6200 rpm shift points and truck spun all 4 again but there were sprinkles between rounds and they did not dry and respray the track. Mods for that pass ProCharger P1(10psi at peak rpm), Circle D 278mm single disc 3200 stall, Klug Performance 93 tune, Black Widow 250 custom cat-back, stock manifolds and stock cats. It was 64 degrees with a DA of 1034 so not horrible air quality.

Now why did I post my 93 times because my one 13.96 pass and consistent 14.10 passes were on e85 and being I am running 93 with the ProCharger I wanted to try and compare apples to apples. Another difference with todays times were I left it in 4wd just to be careful and keep traction. Now in the past I showed leaving it in 4wd versus switching out of 4wd after the launch was good for 1-2 tenths in the 1/4 before on my truck. I am going to Milan Dragway on Wednesday and I will test that out there to see the time difference. I honestly think with better traction, and switching out of 4wd I will see 12s with my current setup. As always the tune is far from done and will keep you posted on all my progress. I am very happy with the truck and think my times today were a very good start.

that's a lot of stress you're putting on the transfer case by shifting it while on WOT. Good times though.

Yeah I use to do it all the time but I'm honestly hesitant being supercharged now. Just a little more power than before. Maybe just one pass to see if it really helps or not. No more doing it on a regular basis.
