Solid Runs Saturday..Special edition Video lmao
 

Put some production into the new bests on Valentine's day lol. Truck was a beast all day, 4 passes and was doing some work on 23-24psi, no nitrous.

Now the bad news is on this otherwise great good day was I under jetted a nitrous pass (didn't factor in my maxed fuel system and pressure drop for the nitrous fuel jet. 1-2nd gears were ok, but third she touch a 12.1 airfuel (24psi+50ish shot) and pushed/melted driver side gasket and some of the head. Block/Piston looks good, so I got a new stock 317 head and gasket coming this week. She'll be back soon.

Enjoy the Video!

Nice work! Did you change the jet on the last pass or not notice it previously?

Nice! You should get ray to port the 317s before you put it back together.

Damn!! Consistent!! Time to go bracket racing!

everything but the lights...

Impressive times!!! Has to be one my favorite trucks for sure.

Your A/F ratio isnt what got your head, the timing was to high most likely. I'll look at your log and tune if you want. I hate to see you hurt it again once you get it fixed.

Truck was on all boost for those passes, but I tried one nitrous pass at the end.. to keep it short it was kind of a perfect storm of shit not coming together and I should have aborted and called it a night. We honestly wanted a 9.5x pass boost only and should have just made one more attempt at it.

Thanks for the help, honestly, but I'll get her squared up. As I told Daniel, I was do for a oil change anyways. =)

After reviewing everything over the first four runs and making very minimal changes, it Def was determined that the truck was perfectly tuned, perfect timing, a/f, boost, etc for its performance. The last run was a sequence of events that we should have just left it alone and let the racing gods get him that 9.5x pass on boost. That being said, it was a "shoulda, woulda, coulda" scenario. Full confidence in robs tuning and triple checking every aspect of the tune. Lesson learned and won't be made again, but the truck will be up and running strong as ever very soon.

Pretty sure I saw the truck being trailered on 26 west while I was going east Saturday morning thinking I wish I lived closer to the drag strip haha...

Yep, that was us!

I do worse motor damage with cruise control activated, so at least you were making some awesome passes before it got hurt...lol

outstanding!

Very nice! :bigthumb:

Like the video! And of coarse the pass... :D

Thanks guys. Got every thing cleaned up, head will be here Monday. Also have another Walbro 450 coming. I was going upgrade the injectors from Bosch 127lb to the new Bosch 1650s till I seen the price.. God bless, they are proud of those little bastards. I'm going to see what these will do with more fuel pressure first.

Damn that truck moves! Nice job Rob:cheers

Are the injectors on gas trucks the same as diesels when raising the fuel pressure with tuning, by just raising the pulse width?

For me in HP tuners you have a fuel table you input injector size and flow at different kPa. There is a few other injector scaling items as well, but that's the basics.

Side note, truck is up! compression and bleed down tests are good on all holes.. She's ready to fight another day. :razz:

New oem 317, swapped duals and good to go.

Seen a picture of the head. Looked like it was hit with a blow torch. You should post it.

Yeah I read somewhere the exhaust gases are supposed to go out the exhaust port, you can get it to leave the head before then but it doesn't pick up power.
