So for anyone local or that wants to know. I am taking my truck to St Thomas Drag strip this Saturday. Test and tune is from 11-4. Last year I did 17.64 at 75mph. Hoping to shave off 2 sec, I have several advantages this year.
I have now drag raced before
My transmission is not slipping!!
Better trans controller with drag mode
8 psi last year now 12psi!!
Shifting 400 rpm higher per gear!!
I think I know how to get boost off the line
After all that I might take the hood off.
It will be, what it will be. I did not build a drag truck, but it's a blast.

Have fun and don't push it to the point you're breaking an input shaft. :LOL:

[rusty76]

LOL well nether.

[lower50's]

So truck did great did 9 runs all better than last year. Last year 17.64@75
This year 16.80@78 woo hoo I'm in the 16's with my 5000lb truck. Still a bit to play with but that will be for next year. I could only get 9psi, so I'll look into that and when I built some boost on the line I spun. But thats for next year. The truck pulled really well and I beat a turbo cobalt!!!!!!! twice. My best reaction time was .13 way better than last year as well.
I'm on the right.

[oldman3]

Lower, glad you enjoyed the strip, getting better each year is a bonus...Jim

[joedoh]

Yup and feels way better too.

[RockinKees]

Great!!
Big improvement!!

I am a dragrace addict, which means I watch it all the time. In Holland we have 1 dragstrip on an airfield... I always watch on Speedvideo the races at your side of the world!!
Right now, this minute is Redemption 8.0 from Louisiana, No Prep.
Within a year or so, we see you race in those No Prep races!!

[lower50's]

Thanks Kees I watch it when I can but don't follow it close. Next spring we are planing to go to the Zmax drag strip and watch 4 wide top fuel tho.

Most of the diesel trucks I've raced would not make the boost on the strip as on the street. I learned that the stiff radials would spin on the track, even when they don't look like it or sounded like it, and you weren't getting the load like you would on the road. Even in 4x4 I saw the issue. The stuff they put on the track to keep the rubber on the grooves is slick if your tires aren't hot. I wouldn't worry too much about it honestly. At least you can make multiple passes and drive it home. That's the main thing.

Thanks for the insight Ryan good to know. Doing the burnout is still my favorite part, and the burnout box guy was enjoying them too. I'm not worried, did 9 passes and the truck just laughed at me and then we drove home pulling my little trailer.

So I had some air system issues recently. About a week ago my air started bleeding out overnight. Found out it was the check valves, so it was leaking back through the compressors. Also on the way home from work last week the compressors never turned off 15 min drive, plugged in my tank gauge 275psi Found out my pressure sw had been collecting water even though I bleed the tanks about once a month. The sw was mounted on a lower side of a T. Now I remounted a new 165-200psi sw up so it can't happen again, new check valves and I finally mounted my 250psi blowoff valve.

My truck has had a slight leak somewhere that i couldn't find. maybe it's my check valve? I added some ping tanks to my rear bags and the LH side has a leak some where. It's always something. Haha

[99 to Life]

my 49' would leak down over night, couldn't find the leak anywhere. then my compressors really started struggling and would pop the breaker. low and behold I changed the leader hoses on my comps with the check valves. I gained like a minute on fill up and no leaks!!

I thought I had a bad pressure switch at one time, I believe it was a bad ground. I bought a better brand pressure switch anyway then realized my ground was a bit shaky.

[Dieselwrencher]

Where is a good place to get a new leader hose and check valve? Mine is currently viair but looks just like the china stuff.

Ya but if we didn't want to work on them we would all drive a new truck.

It is almost impossible to get leak free. Bad grounds cause a lot of people a lot of headaches.

They do look cheap. I put in SMC check valves and reused the leader hoses. So far so good.
