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

[randeez]

havent done much....been getting home late, any days ive snuck out early its rained

got the trans cooler mounted, lines ran to it - had to grab a few fittings to convert the factory cooler block to an but hopefully its done. still kinda close to the driveshaft will throw a strap on the lines, has a full finger away as much has the shift linkage.

grabbed a different coolant reservoir, need to make a quick little mounting bracket for it and extend the hoses to it.

Tune should be ready to load up to get it moving atleast, did the 2bar os, changed to the zl1 map sensor...will still be on stock injectors and pump (ran pressure up to teh fpcm) should be able to drive it around atleast.

 

[randeez]

Well...uh I'm out of injector

50% throttle, 5000rpm, 97% idc ....a little rich just wanted safe tune to start data logging
134kpa roughly? 4lbs of boost
if you look at the purple line second row, its rolling into boost about 3500rpm (105kpa being atmosphere- max on the graph) audibly you hear it start whistling about 2500rpm.
ive still got a few things to button up (power for trans cooler fans) may need to re-rtv the goddamn oil pan gasket, seems to be leaking a little. throw on a few hose clamps for relocated coolant tank

 

[swathdiver]

What are your options regarding the injector? How are you controlling the boost pressure?

 

[randeez]

not much.... its done, thats 58psi and 14v to the fpcm on 93oct too I need to correct the AFR a little bit (shown as 10.7...supposed to be about 11.5 under boost but i just winged the ve tables to make sure it ran safe so it may go a little further.
guess im ordering injectors this week, the stock flex pump should flow a little more at lower pressure from what ive read but it'll need more fuel pump also to get it rockin

6lb wastegate spring, i figured i would start tuning there and add manual boost controller (which would let me run up to 12psi) and that would "hold me over" for a while and hopefully not blow bottom end apart.

 

[randeez]

Coolant tank from a 07ish mustang, same size fitting on the bottom 1". A size off on the small hose to radiator but made it work

 

[randeez]

Took it for a little rip last night ^ that log. Made a few changes will load tune in a bit.
Jump up this morning dropped pan, ultra black rtv on the corners, pan is cleaned and back up already.
Had to use some compression fittings on the trans cooler lines, which leak. Try to tighten those up more and hook up power to the fans cause trans ain't happy
Should be ready for the road after that. May try and plumb the stock radiator cooler back in line if I can find fitting to replace the quick connect
Will prob go grab lunch , let rtv dry up, before I put oil in

 

[randeez]

No more leaks so far...got the tranny cooler fans goin but they can hardly keep the temp down. A little pull shoots temps up 10-15* and it stays where ever it ends up and wont drop tempo down even after a long steady cruise.
Sooo back thru radiator or should I try and remount the 40k in the front grill somewhere?
And 115% duty cycle on injectors should be good right?

What's the worst that could happen, they get stuck open? Then you can just go full booooooosssssst!

Can you remove the caps on your injectors for more flow? Maybe even just for further tuning under boost?

Might burn a hole in a piston if you don’t get bigger injectors. I was running 100% and Justin said no more boost for me or else. Are you running flex fuel injectors? They flow more.

 

[swathdiver]

Hook up the tranny coolers and lines back like stock with the external out in front of everything if possible. Can you put the fan(s) for the trans cooler behind it instead of in front?

 

[randeez]

They are flex fuel injectors, with 93. Was hoping they'd flow a little more so I could have a little fun with it, but 50% isnt even a pull and its wayyyy max'd out.

isnt much room up front james intercooler takes up a bit of real estate, thats why i grabbed a remote mount with fans supposed to be rated "37k" whatever that means. im hoping with plumbing in the radiator cooler that will do enough to knock down some of the heat and the fanned cooler will atleast be able to drop temp while cruising. not trying to auto cross the thing but if temp will never come down after giving it to it thats no bueno

and looks like i'll be checking over the wiring harness tomorrow
throttle position sensor was a little erratic after i updated tune today, drove fine, but its normal pretty smooth on the logs. tried it engine off and it would jump between 0 and about 20%, checked over the tune, compared to old, figured it was something in the tune - couldnt find anything.
key on engine off, when you press pedal it goes up to 100% but still erratic the whole time, unplugged the throttle body all together and it still bounces from 0-20% probably pinched something

Was wondering about that. I saw a build on tv once where they put the trans cooler under the body and didn't even bother to run it up front. They put a fan on it and a duct to protect it from rocks and vent air to it.

 

[crazycrew]

Holy shit, now this is a ******* build thread. Nice work man. Anxious to see once you get those few kinks worked out and larger injectors. Should rip!! I had a 1.32 a/r T6 475 on my dmax, lol

I put a TruCool Max 30k behind the lower opening in the front bumper due to the intercooler needed for the Whipple and it works good. That’s on an 02 though.

I see a lot of diesels do it also with smaller coolers than what I have now so I dont know, I'll keep adding them till it drops temp

The 30k is a few rows less that the 40k right? I have the 40k now and it wont fit there (on the nnbs the opening is blocked off) I cut out to let some more air in that lines up with the bottom of my intercooler tho, big air to air. The 30k may fit there though.

Hoping to have injectors this week, will need to do more in tank pump but should be able to turn it up some. Hoping I'm missing something obvious woth tps issue, unplugged position still spikes, I pulled the pins out of the harness at the pcm to hopefully identify the wiring as problem, still does it!
And it's stupid fast right now, the log of that 50% just sits on the stall, at 4000rpm , and runs thru the gears and wants so much more. I'm real happy with it, the 4.10s may have to come back out if it just rips to redline every gear

 

[randeez]

all the transmission coolers....all of them

@Rocket Man i went ahead and shoved the 40k in front of the bottom grill opening, screwed off the top to the crash bar, let it angle the bottom back and it sits right up against the intercooler i'll find something to put between them to keep then from rubbing but i can get all the bumper hardware back in it's all ****** if i ever rear end someone though

with all the hardlines out i cut down the shortest 90 i could to use on the top radiator fitting that will still clear the intake elbow, will change it over to -6AN fittings and make a hose for it.
ordered all the fittings and enough hose to hook it all back up. at the transmission the fittings that go onto/into the block are a little "delicate" so i dont really want to undo them and will just take one of the lines off of the derale cooler under truck (leave the other to transmission)

so it's going to leave transmission (top hose at transmission) > to bottom of radiator> top of radiator > to 40k trucool in> 40k out to derale under truck in > out of derale to bottom hose of transmission

the fans on the derale I have ran into the cab in the little pocket next to headlight/dimmer switch. I hopefully wont even need to run the fans that much with all of those coolers but it'll be there if i need to mid summer heavy slow traffic i could need it tho.otherwise it gets barely any air flow with out the fans on

Yeah we’re both screwed if we ever rear end someone. I have my radiator, oil cooler, intercooler and trans cooler there and there would be 4 different fluids squirting everywhere.

There were two versions of the WW2 Essex class carriers, one was referred to as the "long nose" because they were lengthened for anti-aircraft guns. You guys could do the same and market a "long nose" version of your trucks to make extra room and ducting for all the coolers and fans.

Ummmm.no. Lmao.
