Yup, did it.

11.951 @ 112.35 1.646 short time.

Stock displacement 6.0L (lq9) in an AWD 03 Silverado SS with a Magnacharger Radix 112 (the little guy) with a 2.8" pulley (9psi). Best part is that it has more in her. I did minimal weight reduction (tailgate removed and no spare tire). I had the heavy ******* Speedstur bed cover ON and had a bunch of crap in the back seat. Better yet, there was a 20 MPH headwind at the track.

Atco raceway ~40*F 2/24/07.

Who is the fastest radix powered (112) ECSB 4x4?

 

I think you have the title! Congrads!!!
Do you mind listing your performance mods?

 

Nice runs. You've got that thing strollin. That just shows how hot the IAT's are with a radix and 2.8 pulley. I'm sure the outside temps were cold and it was liking it.
You better try to better that one soon before it warms up.

 

Very nice krambo!! Congrats!!

 

My IAT's were 92-118 (from start to finish). The ambient temps were 40*F for that run. In the hot summer (90*) they are still only 110's-130's (start to finish). The meth helps but not like a centrifugal or a turbo.

Mods as requested:

ASM headders, custom collectors, dual 3" metal substrate hi-flow cats, 3" X pipe, dual 3" 18"L Magnaflows side exit all 316 stainless, 160 thermo, custom CAI with Volant air box, FLT Level V 4l65E with billet output shaft and Sonnex servos, 40,000 Tru-cool tranny cooler, PI Vig tripple disk lock up 2800 stall converter, FAL 282 E-fans (PCM controlled with manual override), Magnacharger Radix Supercharger w/ 2.8" pulley, oversized heat exchanger, LS2 90MM TB conversion with home ported J-tube, Metco 100MM idler pulleys, 216/222 .559 .566 115 SLP cam, 918 springs - Ti retainers - locks, Gatorback belt, Taylor TV50's, NGK TR-6 plugs, Snow Performance Meth injection (60/40) converted windshield wiper reservoir, ARP rod bolts, Pinned Crank Pulley, clamped rear springs, HPTuners pro (with countless logging sessions and flashes), TA rear end girdle with bering cap studs, Autometer electric boost and FP phantom gauges, Aeroforce scan gauge, Pro-stop x drilled and slotted rotors, Hawk pads, painted calipers with graphics, Konig No-Road 20x10, BFG KDW 305/50's, Goodmark cowl induction hood, ******* Speedstur cover, BSER roll pan with hidden hitch, shopman SS bowtie, silverstars HI/LO and amber DRL's, tint, vent shades, auto trac T-case fluid, Mobil 1 10W30 with K&N HP2006 filter, Watter Wetter, custom plate -SSLEEPR-

I may be missing stuff, that's just a cut and copy.

For the track I use 99-02 silverado stock Al wheels (16") with Dunlop all season 255/50. The combo weighs in at just under 60# each. A set of 4 light DRs will give me a .1 easy as I slip and slid through the 60ft.

I ran a 12.2 in 85* temps over the summer at full weight. I can easily cut 200lbs if needed The ******* bed cover is 100lbs+ alone. Oh and I am not built like Pauley Shore either

 

Wow! those temps are low. My old setup on my 4.8 radix with 3.0 pulley, larger hx with cooling fan and lots of meth i'd still see 170-180* at the end of a run.

 

The highest IATs I have ever seen were in the 160's after hot laping in the 90* heat. A smaller pulley doesn't necessarily mean that you will be generating more heat. If your set-up makes the most power from 3-5K, then spinning the radix as fast as possible and shifting earlier is the ticket.

Trust me though, this thing is pumping beyond its power range. Having a bigger exhaust made a difference in IATs as well.

 

Congrats on the 11's!

 

Congrats on the nice run! Hoping I make it there someday.

 

HOLY ****! Awesome!!!! That is just plain awesome. under 12 in a regular radix kit. Hell yeah!!! Nice job krambo!!!

What kind of spark are you getting from launch to the end of the line? WHat is you afr with the meth? what are your "early" shift points? LOL
