89 c1500 goes 10.6 w/stock long block LQ4 Well guys, I'm more than happy with my first time out in the new setup!!! I love this current setup, only thing I want to change yet is my 3" down pipe, gonna go either 3.5" or 4", it's gotta be holding me back since my turbine exducer is 77.4mm. First pass was street setup with 4" air filter and going through full exhaust out to the bumper on 7-8 psi, I didn't 2step it very hard because it was my first pass and I didn't know how my 2 yr old 30x9 slicks would hook. DA was about 2300ft temps were around 55-60 degrees.
My setup for those who dont know is:
-03 LQ4 with 203k stock long block (bolts and all! just 216/220 .525 lift cam & LS9 springs)
-CX Racing GT45 76mm home made turbo kit
-4L80e w/TransGo shift kit
-PTC custom spec'd 3000 10" converter
-3.42 rear with Detoit Tru-Trac
-4130 pounds with driver
Then I took the filter off and opened my cut-out and turned it upto 12 psi and did this:
MPH is a little down from where it should be but thats because it actually over boosted in third lol, to 15psi, but thats ok I had the tune setup to pull the timing to 10 degrees and go pig rich @ 14+ psi because I'm still on stock head bolts and gaskets LOL First gear never went over 11 psi and second was 12-13 psi. I gotta find a way to fix my boost creep!!! I was running high 10 AFR and 17 degrees to 13 PSI.
Thanks goes out to my bro Jake (Jake99, who BTW also ran a 10.79@125.9 that night
http://www.performancetrucks.net/for...-night-515543/ ) for helping me with all the work of putting this thing together(I started this thing as a roller!!), Kyle @ KB Racing for helping me with getting some parts and some advice, and ESPECIALLY Dusty @ PTC for a kick *** torque converter!!!
