Im looking to get a new pulley and was wondering what boost levels what pulley will net me. Like what size pulley will get me how much boost and what other supporting mods i need to do to achieve them.. I have the stock 2.8" pulley on my m45 right now.... thanks.

This has been previously discussed countless times...

It all depends on what mods have been done to your engine. With my ported head and HO cams I could only get 7.5 PSI with a 2.4" pulley.
i know its been discussed previously but i never saw a real answer and i dont have 23245436 hours to sit on this forum and look through all the posts to find out what i need to know. i have a stock engine 2.4 with a header and 2.25" piping header back and an intake. I also have the MSD coilpacks with the 2.2 coil conversion. i am currently running a .45 gap on my ac delco plugs that came with the kit. are these plugs any good or are there better plugs i should look into getting??? im also ordering meth injection when i get my tax return so i was thinking of going with the coolingmist kit..... any good?? and from what ive been reading u need to get a throttlebody spacer??? i also wanna put my 2.3 ho throttlebody on my blower, what modification do i have to do to it to get it to work???

From your setup I would guess and it would only be a guess.
2.7 =6psi
2.6 =8psi
Yes the coolingmist kit is good.
There are 2 threads already on this page about spark plugs for this kit.
Here is my response to your ? about the 2.3 tb

another thing that needs to be noted is the 2.3 TB only mounts with 2 bolts, a stock 2.4 uses 4. so you will not be using 2 of the holes used for mounting on the supercharger.
also, the gm sc was made to use the stock 2.4 TB, so anything that will work on the stock 2.4 manifold should work on the s/c. which the 2.3 HO TB can work on the 2.4 manifold, ive seen it done.
thanks man, thats the kind of answer i was lookin for....
