Lifted 2002 2500hd build.

I finally got around to doing my 8 rib pullies. With the 10% power bond crank and dropped from a 3.0 to a 2.8" blower pulley. Big change! If only we wouldn't get "used" to additional power! Making about 10 to 10.5 psi now. I may be slipping a little, still using my 6 rib belt. New 8 rib will be here today. Going to try to get a 92 mm tbody and air intake today also if possible. IAT's are about 99 to 104 cruising and quickly go to 130 on hard acceleration to about 75 mph. I have a varima to install and looking to add a second heat exchanger and larger resivour.

Haven't been on here for a while. I just did a set of Speed Engineering long tubes full 3" duals coming out on each side behind the tires. He did an x pipe and 2 3" in 3"out Flowmaster 50 series Delta Flow mufflers. Wow, what a difference! I'm certain the cats were getting plugged up on me. Love the sound too. Its louder outside and a lot quieter inside then the Magnaflow single muffler dual 3" in and dual 3" out. There is no drone. I also took my air filter box out and opened it up a little (maybe a lot). It picked up a lb of boost, just from the air filter box.

I just want to add a few comments. When I first installed my maggie and cam it really felt strong on bottom but lagging on top end. I figured it was the weight of the truck and how the boost comes on with the pd supercharger. I added more boost, injectors etc. It ran better but still really lacked top end. I suspected the converters might be an issue for a while. Then I lost more power. After I did long tubes and full exhaust this thing pulls hard from bottom to top. I should have checked the exhaust for excessive back pressure a long time ago! Same goes for the air intake. I spent a lot of money on this thing and a lot of work only to get mediocre results. I spent an additional $1,100 on my exhaust and and a couple hours on my air filter housing and it made all the difference in the world! Pay attention to the details and check everything!
