I did'nt want to make a new thread so I'm askin here.
I had a compressiontest today before ordering my Vortech next week.. I drove the car for about 10 mins before i got to the dealer (B/C I had read that the engine should be warm) well it took him about 1 hour to get the spark plugs off, and by the time the engine was cold again.. is that a big problem?
my engine is at about 70K miles
but the reading were really good.. I think?
185-195psi all of them

If the crank pulley is smaller than the stock crank pulley (which i think it is) then you will produce less boost.
Truthfully that can be compesated for by a different pulley on the blower. What i would be concerned about is that most underdrive pulley's are cheap junk. They lighten them to "produce more power" but that also means more stress is transfered to the crank. I would use the stock one or a nice dampened one from ATI or fluidyne

With a supercharger your pulley size along with the restrictions (exhaust, intake, etc) will determine your boost. Adjust your pulley to adjust boost and power.

Under Boost!

umm, i wasn't too sure of the question myself..
what i meant actually is, bolting in the supercharger alone, ppl usually get 8-9psi (as a stock notion) or even stay at it just for the sake of being safe.
with my setup, how much should i be looking at? 11psi?
hope that makes sense now.
my setup:
tuner kit Sc-trim
600cc injectors
2.87 pulley
walbro
borla td exhaust
berk hfc

i have a very similar setup to yours and the max boost i've seen is 13.4 psi. during normal daily driving with some spirited runs I usually see 6-7psi not getting over 5k rpm. you'll start to see low vacuum / start building boost around 3300 rpm with the 2.87 pulley and the BPV adjusted down to 6-7 threads showing.

depending on what cams you have an how your tuner decides to use them the norm for a 3.33 pulley on vortech for our motor is low to mid 300hp range. Every dyno and every car is different though.

came back from rt tuning.. i got an 03 vortech z with full bolt ons plenum spacer and bc (264 cams) with walbro 255 and 600cc deatshwerks... i ran stock maf and ran out of voltage at 5800 rpm.. tuning with osiris.. at 5800 rpm.. i made 377whp.. and 310 torque on a dynojet. pretty strong numbers for a 3.33 pulley in a few weeks i will tune with maf.. and see what i maake at 7200... im hoping for 390!

no there not loopy.. no check engine.. there brian crower stage 2 cams.. they work amazing with the vortech .. when i go back to rt tuning in 2 weeks i will tune with bigger maf so i can rev to 7k... and make 390-400 whp.. i made 377 at 5800! and most of that power is because of the cams
