First Time Down The Track

[mitchg]

Took my truck down the track on Friday night. Did its best run launching it at 10lbs. I tried 12 and 15 but the front end hops to much. Im thinking it needs a brace to help it track right. What would you guys suggest? I was looking at the DHD ones. Any thoughts. Also i have my fuel rail shimmed with the ppe kit and i threw a p0087 code on one of my passes. I put two washers in but should i add more?

Im still happy with it for my first time. Cant wait to go back

Be carefull it is addictive, launching at 10-12 psi seems to be the sweet spot for my LMM. Be carefull with your front end untill you get a brace on your center link, I went with the DHD brace and have about 60 passes so far with no issues. What tune are you running? I am having low rail pressure on Robs 230hp max effort tune, after data logging it looks like a CP3 issue. What did the truck run on the pass when it threw the code?

Dhd brace on my lbz. I light up tires before I hop.

Loved the brace on my LBZ. Cut a 1.82 60 ft. On heavy 20s.

It was on robs 230 tune. I had my autocal to log but i got excited and forgot to get it out. It ran a 13.36 at 101.4 with a 1.98 60' spinning a little and hopping. That was the 12 psi launch

^X5 on the DHD brace. Get that 60' time down and you'll probably put it in the 12s. What tires are you on and what did you run for pressure?

265/75/16 Hankook dynapo atm's 50 in the front and 60 in the rear. I was gonna drop them down but i had no way to put them back up for the ride home. Next time ill bring the tankless compressor.

Drop that tire psi to 25 all around

You need a lot less tire pressure. 30 rear/25 front is what I usually run. I don't have a centerline brace and mine doesn't hop at all.

Ill give that a try next time im there. Im going to log my truck again to see if it is dropping rail pressure. I do need to delete the stock fuel filter, it had around 10k on it so that could be the issue.

very nice first pass. That's a good starting point, just iron out the suspension, tires, and steering prep and you are set for 12's all day!
