Perrin crank pulley with vortech, new tune?

You then link to a smaller supercharger pulley. For a supercharger the OP doesn't have.

But i do have the Vortech SC kit

Downshift

You will realize that when you need power, downshifting is the way to do it with a centrifugal.

A 3.125" supercharger pulley will also help the midrange

I have the Vortech with a Perrin pulley and a CF driveshaft. The engine / drive-train feels peppier specially on the track.
You say that with the Vortech, the car is not fast?? My car feels pretty damn quick. I guess it is relative.

I don't understand why people always state that a lighter crank pulley will do nothing for a supercharger. By placing a smaller pulley, you are reducing the mass moment of inertia at the crank and the crank is the main component that drives the supercharger.

It may be negligible at high RPMs, but when you don't see that much boost at low RPMs, I believe it can help increase the angular acceleration at the crank. It works similar to a flywheel.

I have a light weight flywheel and crank pulley.... but on a innovate.... Now to get a 70mm charger pulley.... P.s You WILL see a increase in torque n some slight hp with a flywheel.

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.

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

Again, refer my signature.

Umm???? I was talking about a smaller super charger pulley this WHOLE time mate - please learn to read before spouting your shit towards me - why the hell would you get a smaller crank pulley whilst on a super-charged application? That's fkn ridiculous as you said in your argument it will under-drive the supercharger.

Where in my two posts did i mention anything about a CRANK pulley? I just stated to OP to get a smaller diameter pulley (FOR THE SUPERCHARGER). Jesus, I thought you would've taken that as a given mate considering how long you've been on this forum and the number of posts you've made.

You did not specify what type of pulley you were talking about. OP asked about a crank pulley. Without specifying that you are referring to a supercharger pulley, one can only assume since you are replying to the OP and that you are referring to the pulley he is asking about.

Your initial post is not clear enough.

You keep referring to your signature, which I believe makes you think you sound smart, however it doesn't work that well when you incorrectly spell "you're

OP, changing your crank pulley is not going to make an appreciable difference. Some people might disagree, but when we're talking forced induction, any sort of gain to be had from changing the crank pulley is completely insignificant to what can be gained by changing your supercharger pulley.

By decreasing the diameter of the supercharger pulley, and making sure that your tune is either compatible or updated is going to increase the amount of boost the supercharger will create. More boost can equal a lot more power, if it's tuned correctly of course.

IMO with the added rotating mass of a centrifugal, shaving a small amount of weight off the crank pulley will not be cost effective... the money is better spent on a smaller SC pulley which is less than $100.... another 20-30 for the belt

Just my opinion though

That's actually an inside joke. Willie is a friend with a lot of knowledge that is easily wound up. One thing that sets him off is when you point out that he's used your/you're incorrectly.
