... ok well some of you know of my dilemma with the intercooler on my supercharger and the loss of boost pressure, but i was thinking it over and maybe someone can step forward and help me out with this scenario.

I realize that with the length of piping and size of intercooler some boost loss will be present initially. However I was thinking the system is a closed loop system so why woulh there not be all 9psi after the system has had a chance to filk up. could it be possible my bpv is leaking or possible there is a boost leak in the system somewhere? Just because the piping is longer it would take longer to fill up but once its full why wouldnt it stay full? Im sorry if my explanation is not making sense but now im a little concerned I might have a boost leak somewhere...

If anyone has any input I would really appreciate it. I am running a bosch 110 should i consider upgrading again I am also currently running the ZPI 9lb pulley

 

Try calling Ross at RippMods he can give you a lot of info about intercooling a Vortech unit. Give it a try.

Hey man.. You should definately upgrade.. you know i have a 12lb pulley sitting here at home with the belt just waiting for a home. You should sit BEAUTIFUL with the 12lber and the IC...

 

it is about flow, not holding pressure. Your engine is sucking more air than the ic / pipe can flow so it will show you less boost. Not about filling anything up.

 

I think the prob is the volume of air you are trying to compress, not the fact that you are trying to compress it. You are in a system that is made to lose pressure to the motor. With a stock system you a trying to compress 2' of air in the pipe. the pully is designed at it's max based on that 2' of air to only make 9 psi as your engine is running. Now with your system with the intercooler and all you are running what 7' of pipe and cooler!?! (ahahaha) so now that 9lb pulley is trying to compress "7" feet worth of air while the engine is running. Due to the more volume you are trying to compress, the less pressure you will be able to create. Not sure but doesn't the intercooler make a little restriction too? not sure.

 

Pressure (P) is the force (F) which acts on a given area (A)


p=f/a i think that is the math behind it.

 

cool thanks for the info, thats all what i thought just a guy I work with and I were debating the subject at lunch today.

HM: I have a 14lb pulley on the way, hehe but thanks though

 

This just got more interesting.

 

running a 14lb pulley, to get you back to yer 9 lbs of boost. sounds good but your supercharger will still be working at 14psi

 

Interesting.. good luck bro!

 

Thats what I was thinking, that shaft is going to be spinning extremely fast. If this supercharger makes it with no oil leak then its obviously not the pulleys fault in 9psi setups.

I cant wait to see this. This should be an awesome setup.

 

What other upgrades are you going to be running with the 14lb pulley? I would suggest a bigger oil line for the SC just to be on the safer side of things. Personally I can't wait to see what the out come is.
