Well the other day my airpump seized and I was searching on the forums and found out that with a shorter belt and stock pulleys you would be able to delete the airpump (I know it clogs the stock cat but I just wanted a temp fix). I bought a 300k4 belt and sure enough it started up, at first the belt was too loose so I tightened it. Now when I start it it works fine for a bit then smoke starts to come out either the alternator/pulley. What do you guys think I did wrong?

Thanks

 

could you take pics of how you have it hooked up. That may help us understand better what you may have done.

 

300k4?

I could have sworn the altenator pulley is a 5 rib...

 

Generally, the problem with only using a belt and not a pulley kit is that you need to over-tighten the belt too much for good contact. This can and will wear on the alternator and main bearings. Do it right by purchasing a Greddy or similar pulley kit for eliminating the airpump.

 

decided to put the aipump back on and just disconnect the electrical connector. Car works fine but under throttle I feel a loss of power and a loud deep whine sound. Does anyone know what could be wrong?

Thanks

 

sounds like the internal brgs are gone? causing your noise? if you need an air pump pm me i'll sell you 1
