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.

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

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.

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

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.

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?
