2007 Yukon Denali Build (This got outta hand really quick...)

More snout/blower porting... a few pics of stock blower and my ported blower.

More porting, Brick reinforcement and AN Lid fittings... Swapped the -12AN black fittings out for blue ones you will see in later pictures.




Also, abrasive heaven lol... Don't see too many places like this that carry so much inventory. Was very distracted in this store

Finally got my own HP Tuners cable (3 days before they stopped selling them for the newer unit) Glad I got it when I did since Pro features aren't available on the new one yet... More blower porting pics:

Wow, nice job. Looks to be a huge difference. What do you think will be the net hp difference with the port work?

So this is where things started going sideways... I was finished porting the blower, pressed on new Weapon X hub and 2.5" pulley, completely rebuilt blower with new bearings and fresh oil, reinforced the intercooler brick, assembled the entire motor and reinstalled the entire powertrain (Front diff was out and rebuilt, Transmission was out and rebuilt again due to a bad 3-5-R clutch pack, Transmission reinstalled with the new Circle D triple disc torque convertor, TCI Flex plate and new custom driveshafts installed with the original transfer case)... All that work didn't take too long believe it or not. My issue was with my new 8 Rib LSSimple accessory drive kit. It should have been a direct bolt on and I was truly impressed with he way it LOOKED. It should have bolted on in 15 minutes but it's function however was terrible. I can't recommend anyone uses the LSSimple kits. They had a bad batch of laser cut plates in my case and shipped me a system that they knew was bad but tried to salvage. He elongated holes and used washers/spacers instead of solid mounts. It was terrible and out of alignment from every aspect. It wouldn't track a belt properly even during cranking. I wasted over 6 days trying to make this kit work. I had access to a Bridgeport and a lathe and still couldn't get belts to track properly even after machining new spacers and tweaking things. Murphy @ LSSimple was very apologetic and refunding my money without even asking for the kit back (which is garbage!). That 6 days cost me weeks in the long run.


Looks pretty but doesn't fit or work for shit... Bracket was contacting bottom of snout, had to take out 1/4" of material on the bracket just to start test fitting this turd:




Idlers not lining up at all, the alternator and tension on the opposite side were also canted back in different directions... Still couldn't get it right even after taking the spacers down in the lathe.




Luckily I found a guy locally in Michigan that is very big in the LS Swap stuff... Here is a pic of one of his garages, lets just say he has a few blowers laying around if anyone needs parts ;-)



He hooked me up with a Holley alternator/power steering mount kit and I used an LSA Water pump and factory LSA accessory drive parts for everything else. Came out a hell of a lot nicer in the end and I know I'm running something factory proven and the blower is on it's own 8 Rib belt. Only thing left to do is relocate my factory A/C compressor backwards 1.5" on the LSA A/C bracket so I don't have to cobble together custom LSA to truck A/C lines and electrical. Pics of that to come in the next few days.

Starting to fab up an intake... Originally I was going to relocate the intake to the drivers side and use 5" tube. Unfortunately, the truck fan shroud is freaking HUGE and the bend would have been ridiculous and there just simply isn't a lot of air flow on the side. I opted to keep my passenger side air box ($300+ AirAid) and run my 6" filter to a 5" MAF tube and downsized to a 4" bend into the 4.25" NW TB. Came out really nice in my opinion. (added a new Ice box in the drivers side and relocated the heat exchanger pump as well)
