So i have a ported supercharger with a 2.7 pulley but the needle bearings are going bad and im about to buy a replacement. the new blower is also ported and im switching snouts to keep my pulley size the same. do i need to tune it for the new blower? its basically the same thing as i have on it now....im just a little worried because each hand port is different. I asked ZZP and they said i would be good without a tune. do you guys agree?

 

If ZZP says you're good, then you're good.

 

yep. thats what im thinking too. i was kind of hoping i would run into somebody who had done this before. lol.

 

I would never wing it and not log it. I would at least log it.

 

what do you mean by log it?

 

data log.

 

ok. so just log that i put on a new supercharger for future tune purposes?

 

not what I mean... I mean with hptuners...

 

You should be fine, maf housing size isnt changing so it wont be a problem.

 

Before you go replacing the blower, pull the snot off and make sure the coupler is good first.

But I agree if all you're doing is replacing the blower pack you should need a new tune. I assume you have a wideband gauge? Watch that after you replace the blower just to check.
