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.

Direct Exhaust Ejection?

Bingo, DEE.. been around since they started taking the lead out of fuel. Damn tree huggers.

So after talking with a Tech over at Aeromotive, he wanted me to run twin eliminators or a single Pro. Looking into the cost of that setup to include either fuel cell jazz or sump my factory setup, I opt'ed for tossing one more 450 in the loop & keep my factory setup in place. He also didn't like the -8 at this point in my build as a feed line.

Not 100% how i'm going to configure the basket inside the tank, but the basic will be two walbro's Y inside the tank (currently setup), the last walbro will then Y in out of the tank around the hat. The feed line will be a -10, splitting to -8's to feed the rails. My current regulator is limited at a -6 return, so i'm going to try and leave this second 450 walbro on the same Hobb switch the other Walbro is on and have them only on under boost 3-5psi. If i'm dealing with to large of a pressure surge later, I will have to switch to a -8 return style regulator and use my old -8 line as the new return.

Justing waiting on the -10 25 Micron fuel filter to come in. God speed to red!

That is one way to skin a cat.

I'd run two separate -8an supply lines, one from each pump to each side of the rail, other side of the rail to the fpr. if you still needed a third pump, i'd run another -8an line from the pump straight to the fpr with a one way check valve on a hobbs switch. fuel pressure shouldn't spike too bad since its feeding straight into the fpr.

See if you can get your hands on a triple y-block instead for your setup, I know those y-block cost a pretty penny!

That moment when you drop the tank and find what looks like a piece of the 4.greats piston... All... That motor finally got to go 9s. Lmao.

...if i was gonna run 3 pumps, i would use "monster cable" type stereo wires to power them, and make sure they had plenty of power & ground back there.

your battery puts out 12v, but your alternator puts out 14.4v
you should be able to add a wire to the alternator output post, and apply the 14.4v output to the relay/wiring system for the pump, instead of tapping off the battery, and getting 12v.

if you want to get real tricky, you could run the "sense" line for your alternator back to the very terminal of the pump, and then, the alternator would sense the Voltage there, and try to keep 14.4v on that terminal.

IIRC, they used to sell harnesses for the Eclipses, or one of the rice cars, that ran larger gauge wire & came direct off the battery for a similar effect = more stable fuel psi

HTH, that's a cool toy

copper is copper, dont spend money on fancy oxygen free bs... figure out whatever the largest wire you can land on the terminals is and go with that.

have you looked into a variable speed controller? depending on how much you change with needing to go with a bigger regulator and return line it COULD come out cheaper. I havent looked into those things in a long time tho.
