LT1 with LT4 SC making a weird sound once you let go off gas
Helo,
Im hoping you guys here can help me identify what the problem is? The car never made this before, with 1k miles on this install.. what is going on? If you accelerate and left off it makes this weird screetching sound. I have added a video on youtube.

I dont head a screech I hear more of a rattle. Or am I not hearing what you're referring to?

Honestly it sounds like my car did when I broke the high pressure fuel pump. Was that replaced when the blower was put on?

Hmmm... ok was it measured for clearance properly? Or just slapped on.
Have a look at this thread:

Not like that, if i recall correctly. But it never did this sound, 1k miles no issues.. now i swapped blowers and issue came to light.. swapped to the previous blower and issue still there. So its not the blowers.

To me it sounds like you're misfiring or have an exhaust leak? If not that, then the bypass valve??
Don't assume it's the blower. Could be coincidental too.
