Would it be safe to S/C a 60,000 mile old car? I'm thinking about doing this in the near future and I'll probably be right at 60k when I do it. Any input about supercharging a not-brand-new engine? Good idea or bad idea?

 

Perfectly fine. These 4.6's are great motors. If you feel paranoid about it, get a compression check to check the condition of the motor, and I'm sure you'll see you've got nothing to worry about!

 

What Hx said. likely fine - compression check if you are nervous.

 

Good maintenance record and you'll be fine

 

These cars likes compressed gas!!!

 

Your fine. What blower?

 

You're fine as long as the car was well maintained. Be careful when swapping the plugs when you do the blower.

 

Sorry, I've been super busy. I'm thinking an M90 or a KB. Not sure which one yet though. I haven't really done much research ATM.

 

I wanted an M90 for a while...now it's between a whipple or a KB. I've got a long time before that though, plan to build the engine as well

 

M90 is very safe with the low(er) boost. You'd be fine with that.
