i ended up cutting off the tailpipe (I know, i cut off a piece of art) to only having it turned down over the rear end now bc the drone was so horrible. From my experience, doing so significantly lowers the amount of drone and resonation in the cab, and it did just that so I am happy. here is a quick inside cab exhaust clip of a burnout.

 

How much boost are you seeing with the stock pulley and the longtubes? Stock pulley is 3.30" correct? Im gonna have a near identical setup but I have a small cam as well...I was gonna pulley down to 3.10" immediately and grab some ID850's as well, Im hoping for 7+ PSI and 550+ RWHP on 93...

 

stock pulley that came with my set up is 3.1 and gave me around 6-7 psi completely stock. after lts it dropped about 1psi. I see around 5-6psi now. I just picked up some 83lb injectors and plan to drop down to 2.8 pulley. hoping for around 8-9psi. I want to go cam later on with the ultimate goal over 600+ hp reliable daily.

 

cool...thanks for the info, my kit should be here tomorrow so ill see what pulley it comes with....what injectors did you go with? Im looking at Injector Dynamics, Fuel Injector Connection or Fuel Injector Clinic injectors...

 

found a deal on here on some used Fuel Injector Connection I couldn't pass up. I was originally looking at fuel injector clinic though if I was going to buy new.

 

Kit came today...it came with a 3.30" pulley which it say is supposed to be for 6PSI...gonna order a 3.10" and then see where Im at boost wise...I don't really wanna have to add a methanol setup

 

weird that mine came with a 3.1. is yours a tvs1900 or 2300?

 

Definitely a 1900 kit, I just verified, you had me excited for a second they screwed up and sent me a 2300 kit lol....yah thats really weird...its part number 01-19-60-019-BL which comes up as 11-13 GM SUV 6.0/6.2....

The part number for the truck kit is different 01-19-60-015-BL which comes up as 09-10 GM TRUCK 6.0/6.2 but I would think the kits would be identical, the engine bays are pretty much identical part for part

 

Mine was the MAG011960007 for 07.5-08 Silverado/Sierra with 6.0/6.2. not sure why the pulley size would be different though. your kit may have came with different injectors than mine also since yours is probably flex fuel.

 

When you did the install did you have to splice 2 of the MAF wires to the 2 wires coming out of the supercharger? Also, before you added your boost gauge did you just have the vacuum line at the back of the blower capped off? Any pics of where you mounted the relay for the intercooler pump?

I decided to order a 3.00 pulley and some ID850s...hopefully those injectors are enough to run E85...
