Re: Dragstrip 1/8 video!
:2cents:
Are you driving through the water box? If you are, you want to drive around it.
If you are spinning, lower your 2 step rpm until you can't feel it spin. I couldn't tell from the video, but if your truck starts hopping when spins, you want to avoid any hopping. Hopping is very hard on the transmission, it is probably the worst stress a transmission that it will see. A built transmission will break from hopping.
I would turn your boost down to 13-15psi range and dial in the tune. Slowly increase the boost and dial it in and then add timing. Even a built engine can be damaged. No point in running ~12.9-13.0 quarter's but with enough boost to run well into the 11's. Even with the traction issue, your mph is nowhere near where it needs to be for a 11's seconds pass. You truck should run easy 12's with vortec/cam and 13-15psi. If you going to run alky, I would even run it even low boost, because your going to need to tune it for higher boost levels anyways.

Re: Dragstrip 1/8 video!
Hahahahahaha I don't know but I guess I'm just surprised how power my Sy have.
I kinda don't like awd spin, waste time and speed :-(
I am deaf so I have no idea what I breath or whatever. Lol

Re: Dragstrip 1/8 video!
Yeah I went through the water box. Next time I'll buy a slick tires for it. I set 2,000 rpm on 2 step. I don't feel it hopping at all, just awd spinning.
That's my question, how can I turn boost down and gain? I have a evolution wastegate and knockoff tial. Yes I have alky too. Yesterday I tested launch on highway with datalog and I see almost zero knock which make me happy!!!

Re: Dragstrip 1/8 video!
Your tune is off, so if you dial in your tune it should be faster at lower boost level.
My logic is for dial the car in at lower boost is that it decreases the chance for damage. I would rather slowly nudge up the boost level while check the fueling (and eventually the timing) as you increase the boost level. You will have to play with alky setting as well, but it should give you a handle on how it affects the AFR as you slowly make changes one at a time. You have a new engine setup, you could very have a sensor that is off or mechanical set up issue from the new engine. I know when I swapped in a new engine it took me a little while to fix the little bugs.

Re: Dragstrip 1/8 video!
I bet since I set Timin at zero right now that's why I don't mess with it until everything goes good. Afr read 14-15 cruising and 10.2-10.8 at WOT. I've been eye on afr gauge because it is most important. Also oil pressure.
One thing I'm not sure with fuel pressure at 42 psi and dropped after about 3 seconds of turn key on. Does fuel pressure suppose to stay 42 psi while key is ON? That's only I am sorry about right now. Another thing, my rear driveshaft yoke is completely in the trans shaft, so is that ok? Or should have some gap?

Re: Dragstrip 1/8 video!
with just key on and not running the fuel pump will prime for 2-3 seconds and then go off and restart when cranking and after it has started so that is normal.
with the truck on a drive on rack or on jack stands with suspension loaded you should be able to un bolt drive shaft and push it in to transfer case at least an inch. I all ways do that and mark the yoke at the seal with a sharpe then reinstall it back into pinion and this will give you a measurement. if you do it on a drive on ramp make sure you chaulk the tires. bad story but a local guy removed his drive shaft and did not chaulk his tires while it was still on ground and well he is not with us anymore.

Re: Dragstrip 1/8 video!
The correct spelling would be Chock [chok]
It's a noun and the definition would be:
1) A wedge or block of wood, metal, or the like, for filling in a space, holding an object steady, etc.

It is slang for chock. As in chock the tires.
Btw it should be. Word IS not found in the Dictionary and Encyclopedia. With a period. just saying.
