Left the dealership lot with the first 2018 in Kansas City...
Drove home to install ProCharger (that I pulled off friends GT350, since we didn't make a kit yet)
On the 10-rib, it's really not necessary unless you are really cranking some boost. I'm running the 3.25 pulley and made 793 on MS109. I'm switching to E85 now and should be right around there, maybe a tad more. That was at 15psi before I removed the cats. Now I'm at about 14psi. If I want to run more boost, I'll switch to an OD damper to reduce potential belt slip as I spin the blower up more. Still won't be switching to the 10-rib unless I find one dirt cheap.
I had 1800 miles on my car in August 2018 when I dropped it off to Vortech for their V3-JT smog legal kit. This morning the car turned 26k miles and has been flawless and I beat it like a rental car.
My 2019 had 22km on the clock, I hadnt even seen it. Off the boat and got a Roush Supercharger put on it. Took delivery just over 3 weeks ago and still running it in.
I have a 2019 Premium PP2 that I put a Whipple G5 Stage 1 on my car with 5 miles on it. I now have 1800 miles on the car after picking it up last week.
