do you have a boost guage, if not its a good investment and a cheap wide band too if you can swing it.

the paxton charger is gear driven so youd probably hear noise if it was bad internally. so its either not spinning at the pulley or the belt is lose or old cracked etc. or you have a leak but i think you should hear it if its bad enough.if it was a small leak you would build boost but it would be low and trail off in power.

 

yeah i have a boost gauge and it is vacuum / boost gauge and it hit 0 and not a hair above it.

 

belts are fine how can you tell if the turbine itself is shot i odn't hear any werid noise from the charger then normal.

 

Does the car "feel" like has no boost? Maybe the boost gauge is the problem. If the blower is spinning and the intake path is sealed to the throttle body, It has an internal problem.

 

if it hit 0 the blower is moving air. it just wont push enough air to make boost at the intake manifold (im assuming thats where its taking its signal from. not before the t-body).is the t-body opening all the way?do you have a cooler?a quick test to check for good flow would be to pull off the boot at the tbody and rev the engine a little a good amout of air should come out.rev it with the boot on and listen for high pitched whistling.

Any NA motor will hit 0 on a boost gauge at WOT.

 

yeah i was kindof thinking that the charger might cause a little restriction,if not boosting.

 

i hit zero with out being WOT it just won't go over it. How much for a new turbine if this one is shot? Could not check it today to busy with my other cars to get to my S2K.

 

i was talking to a buddy of mine and we think it might be the MAP sensor I am going to ahead and buy the updated one from Hardtopguys.com


side note the air filter was SUPER DIRTY. Cleaned it all up and oiled it I will see the results tomorrow.
