So big nig, did you get your boost issues fixed?
Ya man.
Been lagging updating here, but Im almost ready to add more fuel to it (Nozzles CP3 later) It pulls NICELY. Just about to send datalogs off for tweaking.. Tax time Ill throw nozzles and a 10mm Stroker at it and make people angry.
Crossposted updates. FUCK YOU:Had a couple issues been trying to iron out... But got it worked out
Ditched the Holley pump for a FASS 150 adjustable pump (Pump only) with the .625 gear... Holley Billet pump just cant hang up top.
Put a derale atomic cooler with fan in it too
And am going to be putting a Wicked Wheel 2 in the Holset I bought today due to inducer wear (I didnt get the damn C clip in all the way evidently and the cover came off a bit ed to one side and hit the inducer of the wheel). The tips of the compressor wheel have notable damage to them ( enough to where the tips of the fins are rolled back and theres too much clearance to the housing, but the housing is fine) and im SURE are making the turbo a good deal inneficieant... Otherwise everything else is good
Ive taken the entire kit off to inspect everything and everything looks great. Changed all filters and oil... Truck sounds amazing
I got off my and built me a mount for the trans cooler that puts it between the tank and transfer case above the skid plate to protect it. Built it out of angle iron then boxed it in... bolted the cooler to it and welded the assembly to the skid plate crossmember. Ended up welding the bolt heads to the mount to make it easier to remove it without pulling the crossmember and painted it. Came out good. Changed the oil and fuel filters in the truck too.
Bypassed heat exchanger, but left engine coolsant running through it for additional cooling, No trans fluid passres through at all anymore though.
Final install
Got the Fass in, things a beast... Makes the Holley feel and perform like a toy, Very happy I went this route.
Slopilly welded a bracket out of some plate I had laying around to mount the pump. bought JUST the pump with .635 gear since I already have a 2 Micron spin on setup I fabbed, and am running a Baldwin PF7977 in the OEM location, Also already have a sumped tank and 100 micron pre filter for the setup, Just welded my mount to the frame, swapped the plumbing over and viola. MUCH better. This thing does like 150 gallons at 30 PSI or something... The holley would start at 15 and when fuel warmed up fall to around 10 at idle. I didint like it, so traded up for this thing (Summits the best, only had to come over the top of the exchange 75 bucks for it).
Pump came out of the box at 30 PSI, I turned it down to 18... Figured that was fine :0
Final install :
So she goes in to get the new cooler, yoke and U-joint Tuesday, the Wicked wheel will be here Thursday... and I need to get the Vanjen and boost brace on it, so Saturday Ill pull the Holset center out, install new wheel... Take off the intercooler and put the vanjen on it and weld the boost brace legs to the charge pipe and compressor housing while the turbos apart, install my home brewed spring gate and let the eat FINALLY
Heres what I got for my spring gate setup worked out. Built it n the lathe at work on my lunch hour and 1 break
:
Keep in mind what I have hasn't been all smoothed out and polished up and whatnot yet. Only thing left to do though now is to cut a circle with a holesaw to mimic the Holsets wastegate bottom, drill a hole in the center for the rod to travel through, and two holes to mount the assembly to the compressor, then weld it to the bottom race (I wanted these to be removable and serviceable as a unit).
Theres a short video at the bottom... Im taking the holset off to put my wicked wheel in this weekend so Im hoping to have this thing done, when Im installing it ill post a video of how im doing the rod extension
Installed height leaves plenty of travel for gate actuation, and adjustment form about 16 to 20 pounds initial pressure, with 25 to 30 on the top when fully compressed depending on how tight its base height is set at. I think it should work well.. based on the specs you guys gave me for your tweaked springate settings
https://www.facebook.com/video.php?v=10152266348550378&set=vb.639350377&type=2&theaterPut this shit in it last weekend:
Got off my but and put the billet wheel in the holset too. The old wheel was a bit hammered from when the compressor was hitting the housing when the ring wasnt seated properly.
Also welded the wastegate spring assy and put the boost brace on it... still need to put the vanjen on the bottom of the tube but ill get to that in a week or so.
Broke the bolt in the vband that holds the center section to the hotside. So had to get creative. Lol. Welded that thing (Ill go get a new one from cummins during the week). EDIT got one... I dont like how the fucking paint had that blue hue to it so Im pulling the compressor off anyway to paint it Silver like it was...
Progress.
Wheel feels good off the hit, not more notable in initial spool but I can tell it comes in harder than the old cast wheel for sure. I could definitely see the transient response being a nice addition to a stick shifted setup.
Next update will be some vids after the tune touch up, a dyno session, then nozzles
Oh, and a pic of your mom...
