Finally found someone to make a pulley for my car it ups the boost from 5.5 to around 8.5-9 at 6000rpms.The guy made a dyno proven 20rwhp at 6000rpms.But the real kicker is 41rwhp and 38rwtq at 4100rpms.Now thats a kick in the pants:o .I am also going to get a WMS CAI Kit it is the only one that is calibrated to a Mass-air meter a ProM 95mm or 87mm meter and the whole tube is calibrated not just the meter it should be perfect for my up coming boost raise :o

 

Is the pulley pressed on?

 

The guy I talked to said mine isnt but the cobra's are.He said all I have to do is take the 18mm bolt off pull at the bottom of the pulley with my hand and tap the top with a rubber mallet.Ill find out soon enough!!I hope that all I have to do..

 

Does 2lbs of boost make that big of a difference because i have a smaller pulley that is supposed to raise my boost on my vortec from 6.5 to 8lbs but i have been to lazy to put it on.

 

yeah .. 2lbs can be a big difference depending on how it affects the tune....

2lbs with a good tune will be at least a solid 20hp .. for a pully swaps worth of work i'm sure you'll like it ......

hell some people spend hundreds to pick up 20 hp even 10hp

 

Right now the car is my daily driver and I dont wanna do anything to kill the life of the motor to much it has less than 30k miles on it now and I am scared that if i do that it wont make it to 30k is it going to be much harder on the motor?

 

Stangerang is almost right on the mark.

According to my calculations bumping from 6.5 PSI to 8 PSI should give you about 5% more power.

 

1 lb of boost is around 12rwhp on our cars if your tune is on.....

8lbs of boost is safe on any car if your tune is right.Make sure you have enough fuel and 93 octane and drive for along time..
