Randeez 2012 Budget Yukon Denali Build (stick on hood scoops galore)

she back .... barely

so i get everything back together, fill coolant and oil....pulled the fuel pump fuse and cranked it over for a while to try and get some oil moved around.
started it up....couple codes : throttle position range, o2 sensor heater circuit . no big deal can get up to temp and whatever took it for a short drive. everytime i gave it a little gas a fuggin "service blind spot monitoring something or another" would pop up and feel like it cut power. hmmmff thats weird, dunno its been unplugged a while figured id just cruise and see if it got better. more warnings, dash lights up power gone, comes back, says low fuel warning so i pull over turn it off (hoping not to be stranded) check under the hood i still have wheel liners out may harness fell into tire, check main ground. turn it back on "seems" ok, drive it does the same thing everytime i give it some gas so crap figured i fried the BCM or something. got back home, gave it one more look over and found that i left the smaller ground on the front of passenger side head loose

tightened it up, all is well took for another drive and all seems good! only gave it to it a little bit, going to put some miles on it before some wot pulls but it does seem to run pretty smooth i had put in 12lb(9+3) wastegate spring prob would have been fine with 93 but it should have plenty of balls there

***meant to say i pulled the 3lb spring back out so it has only the 9lb in it. if the first spring was any indication it will prob peak a psi or 2 above . with 12lbs of springsit may see 13-14psi which i wouldnt want to run very much on 93

Any difference in oil pressure?

Video of PSSSSSH please.

not really

Video of PSSSSSH please.

no pssssshhh for a few days, want to put some miles on it. i ran the dingleberry hone through it and want to give those rings a few miles to seat

At least til Friday night's Test-N-Tune!

Nooo
diff vid than the gmt900 thread, a little more throttle

 

[randeez]

have a engine light for driverside o2 sensor keeps popping up, picked one up to swap in this afternoon.
drove it around a little, seems to be happy at that psi with 93oct, moves out pretty good. will be back to trying to figure out why it wont shift out of first wot in no time

waiting on a few more ptfe hose ends and i should be able to start. reviews said it was a pain in the ass to work with but seemed easier than the regular rubber line to me, i dunno. have 15' of 10an for feed, 15' of 8an for return. cant wait to get back on the e85.

on the fence about throwing a holley hi ram on it lol. would like to do fuel system properly with feeding rails before the regulator. stock rail i am going to have to plumb everything to the reg and then hit rail .

I was so surprised I did get engine light on after my work, we actually checked if it works by sabotaging our work,

didnt*?


i cleared it at first thinking it was because of the ground i left loose but it came back. could have come unplugged or something. i usually tyrap the cable up high or or wants to find its way to the front driveshaft. not sure till i get under there would rather just have one ready to go in if nothing obvious

What can I say, you are correct again it “didn’t “ come on,

That’s ridiculous. I’m so damn jealous..!

So I went to the track last night.....



Need mucho fuel tho only did a few launches, they were filming some street car crap figured I'd draw a few crowds
Ran a couple mid 12s...at 85mph

All was fine, got up this morning at the crack of 11am got some lunch, tries doin a little test and tuning of my own. Ac didnt work , popped hood shredded belt so I cut it out.
Made a few changes, went out and it ended up throwing the accessory belt
got a little warm 250* waiting on tow at the moment. Put belt back on. Right where the belt tensioner is is where turbo outlet is. I think the housing turned enough to hit the tensioner the way the pipes are it wants to "straighten out", pulley on the tensioner is ruined, coolant is all gone out of the reservoir, it's not in the oil that I can tell from dipstick. Going to pull the plugs and turn over when I get home. May have just turned it all to steam it was pretty much straight water wouldnt have to get very hot to do so

 

[randeez]

Basically that area...the housing wants to straighten out the 90 coupler but it rotates instead. but I dont think that's enough to hit the tensioner, think it may have thrown the belt and make tensioner to be closer anyway

and it didnt lose much water, boiled it all out of the reservoir but only took maybe gallon and a half to top off (using small mustang reservoir, prob less than a gallon capacity in it)

 

[randeez]

topped off coolant, shit started right up.....dunno imma just ignorantly beat it till she dies

ill be glad when i never have to make up another braided an line so many bloody pokes

fuel system is under way, I need a handful more fittings to get finished up... was hoping to cut a hole in the fuel tank this weekend but may wait. It amazing how little room there is under there to mount stuff, Im going to sump it in the back. I mounted the pump on the welded crossmember that runs across in front of the tank at the bottom pre-filter going in line where the tank strap is (tucks up nicely there) the hose will stay below the bottom of the tank till it hits the pump. pump and post filter mounted back to back on the crossmember, then hose turns up to engine bay with check valve as close as i could get. will probably be wired to the lowest hobbs switch i can find (1-3psi hopefully)
putting a check valve on the stock pump feed after flex fuel sensor into the regulator. will run from regulator to stock fuel rail with 8an.
ordered new tensioner/pulley, ac belt, handful of ptfe fittings, fuel pressure gauge for at the regulator, small hose for the boost reference.

 

[randeez]

new ac stretch belt installed - installed with tool cause i tore up the other one doing it without it

i just bought an entire tensioner/pulley and threw it on with green belt, only pulley was bad but figured it couldnt hurt.

to deal with the turbo housing spinning: im not sure if this is really even an issue - i took the whole cover off to put turbo drain back on and it's possible i just didnt have the clamp to the center section completely tight. so i may make a couple indicating marks on it and keep an eye on it. if needed i may just get a small expansion pin to locate the cover to the center section.

fuel system - a little more done, fittings should be here in a couple of days, like 10" of crap from the stock fuel line>flex fuel sensor>QDC fitting>union>check valve>regulator. need to make a easy L bracket for the regulator to mount to, moving the catch can and remount it, the return line has a nice spot to leave a little extra hose so i have that entire hose made up with some slack. soon as fittings show up i can make up last feed hose and locate the sump - i know i should start at the sump and work my way out but it just worked out to where i could complete 10% of it and be short a fitting or do 90% and be short a fitting

 

[randeez]

And wire it up of course

 

[randeez]

Eh 5 min bracket should work fine lol

 

[randeez]

I'm pretty laid back, not many things get me shook, but drilling a 3"hole in my gas tank took a bit to get hyped up for lol
Secured the hoses to the outer shield (not shown) first pics look like they're close to driveshaft, second pic shows how much room there is between. will do something a little more permanent eventually. the "wet" looking around the sump is some petroleum jelly - wanted to make sure that o-ring could seat and not drag the tank, it is actually kinda rough.

bunch of boring theory i have for making this all work:

"integrating" an auxiliary fuel system isnt just going to hook up and work seamlessly. I will probably be messing with pressure in the fpcm and on the manual regulator for a while until i can find a happy place to set everything up.

with the fpcm base pressure is 43psi, when needed (high load) it ramps pressure up to 58psi and then does some tapering off as you get higher in the rpm. which is all programmable. I wanted to keep it this way cause i do intend to cruise this thing when all the bugs get worked out and dont want to hear a huge pump whining the whole time.

got everything plumbed in, took a short drive (needed to put gas in it anyway) using just the stock pump. with the regulator set above 43psi fpcm doesnt even know its there - good start

i just need to wire in a trigger for the aux fuel pump relay, so its not "finished" up just yet. it'll get a bypass switch anyway so i may throw that in to control it now. i have a hobbs switch on the way to trigger the relay low psi in boost. I think setting the fpcm slightly above the regulator pressure would work the best. ie- 55psi on the regulator and 58 on the fpcm or something like that.

im worried if i set the regulator pressure higher than the fpcm that it will overpower the stock pump (which now has a check valve) so i wouldnt log my fuel pressure accurately. (sensor is halfway down the truck on stock line)

Wow. This ***** is going to eat some fuel, and scoot. Sounds good man! I understand the theory, but yeah, you need some cajones to build that! Nice work!
