TBI sucking sound
Well it's been awile. I got it running. I installed a 330hp Vortec 350 in my 91 RS convertible. I did everything rite. Well I spent alot of money anyhow. I had Sean build me a 46mm TBI to put on the GM performance intake which I had bored to 46mm. I havent got the EBL tuned rite yet. I still need exhaust. Open headers for now but I plan on 3" pipe w/no cat going to a Magnaflo muffler. I have a question. The TBI is really loud. You can hear it over the headers. How do I fix that?

Re: TBI sucking sound
You can't. Its the sucking sound of air rushing into the motor. At least thats what I think you're explaining.

Re: TBI sucking sound
Even my little 5.0 makes that sound especially in open-loop. With a open air/filter top element its even louder.Once it hits closed -loop it is not as bad.(air rushing in,no whistling)
