I'm about a month away (May 10th ) from having the coldside on the car for a year.
As of right now, I'm burning oil quite a bit. I actually look like a crown vic going down the street instead of a Miata...
I have the perpetual blue cloud following me.
I think it might be because when I got the car (way back a few years ago) I found the car was running over 25 degrees advanced timing. So I imagine the fact that it was running that lean and pinging for who knows how long, that it did some sort of engine damage.
The cars only got about 136k miles on the chassis and motor. I drove the **** out of it for years, and even more so when I got the supercharger on it.
I'd highly recommend getting the bigger throttle body for the supercharger, along with a nice flowing exhaust system at 2.5" .
And a little further down the road when your done using bandaids, get a megasquirt and get rid of the AFM and run a cone directly off the supercharger
Good luck, it was an easy one day install for me to do.
