GTP = BEAST
so i installed the boost gauge on my 04 grind prix gtp and im gettin vaccume but when i floor it i hear my supercharger winnin but my boost gauge aint showin no boost i think i hooked it to the wrong place i hooked it up to what looks lk a vac source or something its on top the s/c
 


lower intake manifold.

look under the snout of the supercharger, there will be a vacuum T there, follow it and find a spot where you can T into that line.

ok so how to i T into that little ass line ?
Click to expand...

take the L nipple off your MAP sensor (it will be the final place the vacuum line goes at the rear of the supercharger), replace it with a T, and continue the line to the cabin of the car.
 


Do you have other mods done before you just slap on a pully??? better have a good amount for that size.


EDIT!!! On a 04!!! thats like dropping to a 3.0 on the 97-03 that would be insane without a ton of mods!!! plus a way to scan for that knock
 


You are going to need more like headers, intercooler/ cam, and a really good tune for that pulley
