08 Vette Vortech V3si and Kooks
3.6 pulley on a v3s trim. Kooks longtubes with cats. Stock everything else power wise.
Was seeing about 8 psi at 6500. Crap 91 gas and a fair amount of 50/50 water/meth on top. My glory pull was 608 with 15 degrees and it only picked up a couple from the much safer feeling 13.5 I left it at. Didn't figure out until I got home one of my vacuum caps pushed off before or during the dyno session. Good news is a picked up about half a psi. Bad news is now my tune is off again. Oh well back to the dyno after I chase down my other gremlins. Hopefully see a few more ponies.
Don't beat me up on numbers. Yes there were some other little pieces involved. Yes my headers/clutch are not included in that cost. I've got under $2k in the kit. I wanted to hit 600rwhp and have a car that drives stock outside of boost.
08 LS3 - never had the valve covers off.
V3si with 3.6 pulley - used $750
A&A Bracket 6 rib - used $300
Intercooler - procharger used $200
HD Green Belt - ebay $25
60 Deka injectors - used $200
Filter - A&A $75
Air Bridget - A&A $109
Boost a pump - used $150
Hoses, couplers, all cold pipeing - ebay $150ish
For the people that are trying or considering building your own kit. This took me a year to source parts at these prices. For the cold side if I ever do another one off again I will by the A&A parts. The few dollars saved in the long run is nowhere near worth the trouble of piecing together Goodyear hoses and never getting the intercooler where you want it.
I definitely had a leak. The line on the intake just behind the TB came off. I now see maybe another .5psi. I would bet money my intercooler is more restrictive than the new A&A intercooler also.
50/50 because I wasn't crazy about putting something flammable in my WW tank. I will hit up the local distributor before going back to the dyno and see if there is a big difference.
Seems most safe tuned 3.8 pulley ls3 cars are making 550-560. I thought 600 was pretty decent for a bolt on car.

Silver... where in the world do you see 13.5 air/fuel?
I dialed it back in to 604/555 yesterday. Up half a psi and down 2 degrees. I made pulls and tuned on a bunch of cars yesterday so didn't have time to really abuse mine. I'm good at that point anyways. Don't want to be meth dependent.
Seems to be the sweet spot. More and you get into fuel systems and more driveline issues. Already having to deal with wheel/tire issues.
Sleeper vette? lol.
