running without S/C belt?

[FoSHO99]

A turbo guy dynoed the stock l67 block with a blockoff plate on after removing the snout and rotors for the supercharger and it dynoed at 147whp I believe.

Wow... did I get some attention! lol

My car was hitting 10* of knock at times... it was slow as heck (due to timing being pulled) and about to chip a piston. My mods in my sig haven't changed... A stock pulley would just be a waste of money and time putting on... My mods easily support a 3.4, I just need to get it scanned and get the problem fixed (I'm guessing tune issue or lack of fuel).

I have the same knock/gutless problem, and similar mods. I have DTC P0134 (front 02 no activity) which is hopefully the cause. Thats probably a result of extending the 02 harness.

Will be fixing this when my life allows me.

I feel its still safe to drive without boost, with the SC belt on.

Yeah, that might be the problem... come to think of it I get a random P0133 every once in awhile....

OOOOOOOOOOOOOOOOOOO...can I borrow your motor and check it with a ?stethoscope??

I wanna look for chipped pistons

Whose? Mine? Sure, if you send me the money to ship it to you I'll be more than happy to send it your way....

It doesn't have any chipped pistons... I pulled the belt off it to prevent that. It runs like a champ without the belt, and pulls 20 inches of vacuum. Idles perfectly. And if by some small chance it did... who cares, still runs good for my DD.

dont run without it unless its a emergency and dont give it too much gas (activate boost)
