Perrin crank pulley with vortech, new tune?
 

Just wondering if i decide to get the perrin crank pulley will make for better acceleration or make the car feel better, and if i need a new tune for this?

Mainly concerned if i need a new tune for this

To answer you question No, but the mod isn't worth it.

Why is that?

I seen people say its night and day and people say it wont make any difference.

Its the same people who say a catback made the car much faster too

My 2 cent though

I agree that it isn't worth it when you have a Vortech, and no your won't need a new tune for one. Changing pulleys is something naturally aspirated guys do when they are looking for one or two more ponies.

^^Agreed. I actually went back to the stock pulley, and went with a lighter flywheel. Much better results:thumbsup:

I see, well the acceleration is not the greatest sometimes, anything else i can do besides E85?

I think what OP is looking for is a smaller diameter pulley, rather than one that is lighter. A smaller diameter pulley will make the "night and day difference" you were looking for as it allows you to run more boost.

He wasn't asking about a smaller crank pulley.

And ileven if he was, you're wrong anyway. A smaller crank pulley would under drive the supercharger.

Then what's that? I don't know the exact dimensions of the stock pulley so I assume the ones that raceseng produced are smaller - smaller = more rotations = more boost

Also, vortech can provide you with options of purchasing smaller pulleys with their kit so you can run higher boost levels.. now please retract your statement and apologize.

A pulley for a supercharger, a supercharger the OP doesn't have.

Please refer to my signature.

I won't retract nor apologise, YOU are wrong.

OP is talking about a crank pulley.
You said a smaller crank pulley will increase boost, it won't, it will drive all accessories including a supercharger slower.
You then link to a smaller supercharger pulley. For a supercharger the OP doesn't have.

A smaller supercharger pulley will increase supercharger drive. But a smaller crank pulley will have the opposite effect.

Again, refer my signature.
