holley whistle
i put the new holley systamax on. got the car started up big improvement. but when i rev up around 4000-5000 it makes this crazy whistleing sound from inside the manifold area.so the first thing i checked was all my vacum lines they are in great shape hooked up right. i checked all my manifold bolts they were good. i cant find were its comeing from the car idels fine. anyone know?

You didn't notice the turbo that's on your car??
haha, just messin. I've heard of aftermarket TB's whistling sometimes, I think it's the BBKs. maybe there's a casting flaw inside the manifold or something?

Stock tb and egr but man did i clean them out.. the egr was caked in carbon dust same with the tb. my friend thinks its the manifold. He has a trickflow on his mustang and around a certian RPM he said it sounds like its burping. and no to the turbo thats my next project for the 408 stroker

sorry nno help on the holley but i have something similiar on my 306 with a edelbrock rpm 2 it is a whistle like right off idle and when u rev it up and it goes away around 3000
i thought it was my tb as my previous motor had a 65 mm bbk and it whistled not like this or like yours it sounds like it is the intake as you are describing too i thought it was my baffle ove rthe pcv hole but no. mine sounds like **** too wtf[8D]

What happens sometimes with the aftermarket TB and intakes you will get sharp edges where ports are drilled. For examplea sharp edge on the inside of a intake where a vacuum port is located. If you take a file to that sharp edge the noise will go away.

take the belt off see if it still does it... my car used to make a loud whistle noise around 4000rpm all the way to 5500 rpms when i shifted and it was the A/C compressed pulley scraping on somthing
