Plenty of whipple cars go 100k
You try to make a ton of power and beat on it every day, you're going to break stuff but that goes for a non-supercharged car, too.
On the plus side, with the tune that comes with the supercharger the only tune available, at least you don't have to worry about it have some shitty tune from a hack tuner on it.
I'm just saying that's not uncommon to end up happening
In the old days guys were upgrading their superchargers as well. 2.3 to 2.9, VMP gen2 to gen3 etc
$15k for the initial install
Another $5-10,000 in random upgrades (headers clutch tires wheels suspension etc)
$10,000 in a new shortblock or built trans at some point
$1,000 for another tune
More misc shit down the road
Go 285/35. Why?
285/40-19 is a bit tall for the front at 28"
285/40-19 tire selection stinks. A couple decent tires and then mostly OEM SUV sizes (BMW/Porsche etc)
275/40-19 is a hair narrow on the 10" wide wheels. Works but just looks a little odd.
