  1. This is a brand new 2.8 inch (71.12 mm) 6-rib pulley that I have to take a loss on. I installed it, turned on the engine, threw the belt, and realized that the offset was wrong for my blower (which meant this pulley stuck out too far and misaligned my belt). Oh well, can't dwell over it, just gotta sell it. So yes, this pulley has ZERO miles on it. If you don't know about GripTec pulleys, here is the link to the one I am selling. Basically, the ribs and grooves are roughed up like sandpaper so there is less belt slip, less knock, and more boost. Magnuson TVS Pulley 7075-T6 Ø 2.80" 6Rib Level 3 Black Ti bolts - Z-Industries, Inc. Store I'm located near Van Nuys, CA and will ship anywhere in the US for $110 total.
  2. Any used complete whipple or magnuson supercharger tvs1900 or tvs2300 kits for sale? Looking for a complete used kit for my 16 5.3. Not going to pay 1k less then retail for a used kit.
  3. Hello, I have a 2017 Sierra SLT Crew Cab 6.2L with a Magnuson TVS1900 on it. The pulley and boost are stock from Magnuson, so probably 8psi max boost. I want/need to replace the spark plugs because I get a little bit of ping when really engaging the supercharger. The ping is very short and goes away, but it even does it with around a 94 octane (mixed 91 with 100). It is much, much better with the 94 octane, but it is still detectable. My questions are: 1) Should I get a one or two step colder plug? 2) Should I lessen the gap to 0.028in or 0.03in? 3) Should I get projected or non-projected tips? 4) THE BIG QUESTION, do I need to get the exact same size plug as the stock ACDelco 41-114 (aka GM part number 12622441)? The REACH is what seems to be different. I believe the stock plug specs are: Heat range: 16 Gap size: 0.04in (1.02mm) Reach: 0.98in (25mm) THIS IS WHERE THE NGK PLUGS DIFFER Hex size: M16 Insulator height: 0.99in (25.3mm) Seat: Tapered The plugs I am considering are Brisk (which have the SAME reach) and NGK (which have a DIFFERENT reach). Eight of the Brisk plugs is way more expensive than NGK. Brisk RR14YS - two steps colder, projected tip, 0.028in gap, same REACH as stock Brisk RR14S - two steps colder, non-projected tip, 0.03in gap, same REACH as stock Brisk RR15YS - one step colder, projected tip, 0.028in gap, same REACH as stock Brisk RR15S - one step colder, non-projected tip, 0.028in gap, same REACH as stock NGK BR7EF 3346 - two steps colder, non-projected tip, 0.28in gap, 0.709in (18mm) REACH which is different than stock NGK BR6EF 3177 - same but one step colder
