I had the supercharger and water pump replaced, and now its making a noise like its sucking in extra air somewhere. Its pretty loud and noticeable. any ideas?

 

Is it noisier on the inside of the cabin? What does it sound like?

 

outside. It sounds like i have a cold air intake (that kind of air sound but way louder than just intake). sounds like a vaccuum line wasnt hooked back up but its running fine and i have no idiot lights...

 

anyone?

 

Your on the right track, grey vac. line to the pcv/supercharger. A flipped Intercooler boot, etc...

Intercooler boot(s) may not be seated properly.

 

It sounds like its coming from the intercooler area. how can I fix it?

 

its under the intercooler i fixed that and the boots and gained 50fwhp on the dyno... its under the ic... look for it! grey vaccume line! cap it!

 

assuming it is the boots that are leaking the above job should take no more then 1/2 hour. You will need a TORX socket set, I don't know the size of the bit though all are the same. There are 4 TORX bolts holding the intercooler cover on, I believe the ones up front have no nuts beneath the intercooler though the back ones may have. Be careful and reach under while undoing the back bolts on the IC cover. These bolts attach the IC to the engine. The IC is now free of fasteners. The IC cover can come off now. Put the bolts in the IC cover so that you can remember where they go later.
There are 4 bolts on the clamps on either side of the IC, all are TORX of the same size as the ones on the IC cover. Undo the bolts and remove the clamps. Pull the IC to the right and reach under the left hand IC boot. Feel under there to determine if the boot is properly seated. If not, pull the IC further to the right. Lift the IC on the left side slightly, this should relax the boot enough so it will allow the boot to seat properly. Push down the IC on the left and pull the IC to the left. Repeat for the right side. The only problem I ever had with this is getting the clamps back on, be patient. I don't know the torque settings but I would use no more then 20 lbs/ft for all the TORX bolts.

There is a vacuum/pressure hose from the right side of the intake manifold that attaches to the fuel (pulse) regulator on the fuel rail. It may be disconnected at either point. Remove the intercooler, if it is off the intake manifold side it will take angled needle nose pliers to reattach, if it is disconnected at the fuel rail, you can put it back on with your fingers.

 

I took off the intercooler and adjusted the boots, and there are no hoses loose. Is it supposed to make the sound of air rushing normally and my supercharger was just shot?

 

hi, did they change the green seal that goes from the plastic runner (tube) between the TB and SC? It hardens up after time, if the shop didn't replace it, you should ask them to.

Sorry- should've specified that the seal goes between the runner and the SC.

 

long time no read! You beat me to it....

IT's hard to have a leak from the TB to the intake plenum that goes between the TB and the SC, but it's easy to have a leak at the SC, especially with hard gaskets. Also, the hoses that go into the plenum (at the red thinggies) should be in to the point that the raised edge is against the red ring. Sounds funny, but it makes sense when you look at the parts. They may not be seated well.

There is also a line that goes from the SC to the valve cover. To find the leak, use a length of vacuum hose or something to poke around while you listen to the other end. This is a poor mans mechanics stethescope. It will be very, very loud where the leak is.
