Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

[95escahoe]

Everything with the new trans and driveline parts seems to be holding up well so....ordered a 3.375 pulley for the Whipple today to replace the 3.75 that came with it. Boost should go from 6 to 9 psi. Woo-hoo. Justin at BB said I'll be at the limit of my PCM as far as airflow. Possibly could go to a 2-bar tune, whatever that is, if I want more. I'm thinking I'll be good. Thing is already a beast.

How much hp & tq are you looking at with the new pulley?

I honestly don't know. I plan on a dyno run but last time I checked with the one AWD dyno I found so far had a 2 month waiting list. I'll have to do some more looking or go ahead and book a run in December.

Lol... At first glance, I thought you were changing wheels...

Question, what fuel pump are you rolling with?

Stock. According to Whipple and BB it's fine. The 5.3's and pickups need bigger ones. Justin said I'll be ok with the pulley I ordered but if I go smaller I'll have to look into a couple things, fuel pump probably being one of them as well as injectors and then there's the airflow limit with the PCM. I probably wont do that since an injector swap means pulling the blower. There's this one bolt on the fuel rail I can't quite get with the blower on. If it wasn't a DD I might go farther but I need it to be reliable. Besides, my last tank of gas , which was mostly short trips around town and of course I was on it constantly, netted me 7.7 MPG. I did a highway run a couple weeks ago and got almost 11 but that was entirely highway.

The DJM bushings came so I fixed the rear swaybar. No more clunking. They sent the entire set so if I ever have a problem again Ill have the parts. I went ahead and lubed all the bushings while I was there.

Was your rig a flex fuel vehicle or no?
