Yep, the LSA supercharger was hard on the 5.3 rings so I got a LY6 and built it myself.
Forged pistons and rods.
Long tube headers 3.5 inch exhaust
LSA blower at 12 psi.
32 inch tires 4x4
473hp @ 6000
Conservative tune for towing in the heat.
4.56 gears are next
My clearances are .0026 0029
Melling high flow high psi pump with 40 weight it idles at 35 -38 psi hot.
Still working on the tune to make it shift smoother.
What are you towing? Do you run premium fuel?
Towing with a supercharged gasoline engine in Arizona heat is about the last thing I would attempt.
How large is the intercooler radiator? It better be about as big as the main engine radiator, perhaps bigger.
