I've seen some claims of 800+ rwhp over on tech, but pretty sure those are through 6 speed cars.

Like Vortech350ss and Team Kurt, I was estimating somewhere around 750 on mine as well with a trap of 126 mph at 4550 lbs. I was shifting at 7200, blower speed at shift was 106%. On mine at that blower speed the boost had flatlined but was not falling off yet.

I say turn that bitch up as hard and as high as it'll go. You got a bad *** truck for sure dude.

 

Thank you! Called procharger yesterday and they dont offer an 8rib setup for the 14+ trucks so I'm going to have to stick with a 6rib unfortunately, but they said a 3.47 pulley is gonna be the limit of the blower for me and they dont think it'll slip so I'm currently having a 3.47 griptec pulley made lol adding another meth nozzle as well and gonna max this d1 out lol. Might run out of lowside pump but we are going to do a bigger one if need be! Currently the truck makes 700rwhp/637tq in like 108 degree weather I think it was, and that was with a 3.7 pulley

 

And also pray thay the stock bottom end/stock trans lives, they havent skipped a beat yet (and I dont drive it nicely) so we'll see

 

I need to find a way to cut weight too.. Mine weighs 4860 with me in it =[

 

I don't recall your exact exhaust set up, but a 2" header at that point with cut outs is gonna be worth quiet a bit. If you can swing the cost of that mod along with the new pulley and extra nozzle I see big things in your future.

 

Right now it has 1 7/8 longtubes/catless y pipe/3 inch exhaust/muffler dumped in front of the axle, you think the 2" will be worth the money? The shop that does my work can make some pretty easily, they make 2" for the c7's. That might be something I do when I do the forged motor

 

I can say without a doubt the best bang for the buck right now will be going to a 4" over the single 3" you have now. That's a serious choke point.

 

So going to 4" after the y pipe will be good or should I ditch that y pipe and do something else? Hmm I need to get this stuff done soon, hoping to have it on the dyno in a month or so, they told me the pulley will take like 2 weeks. Gonna be purrty lol

 

4" should do the trick for now. Assuming it Y's from dual 3" directly to single 4" and doesnt neck down to a single 3" for any period.

That pulley is pretty!

 

what is your exhaust setup? this weekend i'm installing some ARH 2" with 3.5 collectors and have a dual mandrel 3.5" exhaust to install behind the headers. the pypes setup has an X pipe, and i'm debating losing the X and just running 3.5" exhaust straight to my bullets with no X.

don't know if it's even worth worrying about.
