Bargain week

gmfan24 · February 25, 2017

So... just got home about 15 minutes ago. First off, the injector data I got from the LS9 injectors in LS1 file that I downloaded from the HP Tuner Tune Repository was dead on, to say the least. I mean, I had to recalculate the IFR for 50psi, which is about 52.4lb/hr, but I did that months ago. By dead on, I mean the truck started right up cold, and ran like a sewing machine. THE FUEL TRIMS WERE LITERALLY +/-1 UNDER NORMAL DRIVING CONDITIONS. My mpg was up by .7, until I started pushing the loud(er) pedal. Lol. I didnt get as many pics of the supercharger install as I would have liked. I was thrown a few curve balls along the way. Number one was my broken oil fill extender, which half necessitated doing the valve cover gaskets. My oil fill cap now screws directly to the valve cover, with a new AC Delco o-ring on it. Curve ball number 2, and the other half of necessitating doing the valve cover gaskets was the driver's side cover itself. Apparently I missed the fact that I had no serviceable pcv fixed orifice from the factory. Oops. Kinda need a place for the boost resistant valve to go. Luckily we had an older engine with a removable pcv valve nearby, so I traded valve covers with it. So that added a couple of hours to the job. Yay. Darn those coil brackets... Next surprise was my valley cover leaking at both ends. Glad I never put the big steam pipe that connects to all 4 corners on. Next unplanned occurrence was breaking one of the knock sensor connectors during removal. Crap. Lucky for me, Autozone is open till midnight, and they had such a pigtail in stock. Naturally, I just used the connector part of it. Also replaced the oil pressure sensor while the intake was off. Just because. Yep I fell asleep in the middle of a post. Got home about 0415. So, my lack of pics is mostly due to the extremely nasty jobs of doing the valve cover gaskets and valley pan gasket. By the way, the coil brackets are just a little bit frustrating. Especially the passenger's side. Moving forward, after getting the intake manifold installed, parts transfer, and prudent modifications, we moved underneath and set about changing the oil and installing the pressure amd return oil lines. I used Mobil Clean 5000 High Mileage and a PF46E that I got at Wal-Mart. Next oil change, I believe that I will use PF61E, since I have the space to accommodate it. Blah blah blah blah blah. Used a 45° Push-Loc to -8 AN fitting at the oil pan for the drain, and a 1-8" NPT to -4 AN 90° fitting on a modified oil cooler delete to connect the pressure line. I'll compile and post a list of exactly what I used later this weekend. Y'all want pics I reckon. Here we go.

Forgot about the pics and missed the first few steps...

Ewwwwwww. That's yucky. Also detrimental to air control.

No more oil fill extender.

Oops.

Little parts transfer

Prudent modifications. Those are 3M mounting tape squares with the peel off paper left on the bottom one. The map sensor is not going anywhere.

Vacuum lines for bypass valve, and pcv inlet side in place, kinda. Also, 2 BAR connection at unused brake booster port.

AC Delco IAT sensor in modified discharge tube. Actually fits better than the aftermarket one O had...

Good enough to tune with, gotta go back and teim some things, put split loom on some wires, etc...

Got a couple of videos, taking a while for them to populate in Photo Bucket

gmfan24 · February 25, 2017

Ok, please someone help me spread the eargasms by getting my videos in a post. One is 7 seconds, the other is 23.

gmfan24 · February 26, 2017

This is all I can do for now...

Not sure if I mentioned that the supercharger moves a TON of air. When we first started it, coolant temp was about 75°, so it was in fast idle mode. MAF was showing 4500hz idling. Jumpin Jiminy! I may have to go to a 4" intake and a card style MAF, but that will be later.

Got the LED's put in. Yay! Both of them work! Totally different gauge appearance.

Illumination without projection. SCREAMS Autometer. Love it!

Been data logging on the way to work with HP Tuner last couple of days. Just normal driving. Fuel trims look great. Going to look over it some more and see if anything needs little adjustments. Punched it yesterday at lunchtime and it felt like something was holding it back at 2.5psi. I realize that's not very much, but it felt like it hit a wall there. Probably going to log some spirited driving at lunchtime today, maybe see what's going on there and if I can change it.

gmfan24 · March 1, 2017

That was a fun drive. Goes from 20 to 80mph pretty quick

Showed 6psi at 3500rpm. I'm sure that will be less in the summer.

gmfan24 · March 1, 2017

Must have been me being a wimp with it. No wall hitting today on the lunch time runs.

All the bargains, all the post, and all the pictures are WORTHLESS without some video at the track laying down some serious times and videos on the dynamometer showing something like 10,000 HP. I guess we would accept a video of the Suburban slaying a Hellcat in place of the dynamometer.

I haven't said anything, but have been following this one for a while...been enjoying the write up and pics. Looks great!!

Lol Muddkatt. Ever tried pulling the reins on 6000lb going 80mph in a 35 zone when the traffic light changed on you? I ran it because thw ticket would be less than replacing my laptop, had it flown off of the seat. If someone could guide me in posting a video, I will post several. I'd be happy with 450hp. I'm averaging 10.6-10.8mpg in town without boosting it. Not too bad considering that I was at 11mpg before the supercharger. I have a very "safe" tune at the moment, which combined with the wall wetting spray pattern of the LS9 injectors, the extra drag of the supercharger on the the FEAD, and the ability of said supercharger to move such a quantity of air at such low rpm as to drop intake vacuum to 0 at a mere 36% throttle, isn't too bad. I may experiment with rotating the injectors a bit and see if that helps fuel distribution any. Probably won't, as my fuel trims are still +/- 3 or less at idle and part throttle. I'm more concerned about scouring cylinders due to ring wash, or clogging my cats. Then again, I don't think .4mpg less is drastic enough to do that. Had a funny thought yesterday. Imagine how clean my intake manifold will be inside with fuel evaporating off of the port walls and breaking up the pcv gross after I shut the key off...lol. Like I said before, I have a local quarter carwash that does a darn good job for that. Speaking of which, here is my factory intake manifold, fuel rail, and injectors after a trip there.

That's water...

Much easier to remove it all together.

At Gas Monkey Garage the bearded wonder always says that bigger brakes are needed to whoa it down after giving it more power.

Try uploading your videos to youtube and posting the link instead of using photobucket.

gmfan24 · March 2, 2017

Indeed. PPV brakes have always been on my mind. Probably will when the fronts need replacing. I always make sure no one is within 3 blocks in front of me when I hit the loud(er) pedal. Good idea about the YouTube thing. Gonna try it.
