No power after shifting and weird noises

[Monroe8822]

Hey guys I am having a problem with my motor here recently I changed superchargers on my car and added a 3.4 pulley to help my car out some because it is low on compression. Anyway when going WOT the car pulled hard all the way through first gear but as soon as it shifted to second it fell on its face and almost died had no power at all and when I would give the car any gas it made a weird rattling sound which almost sounded like a bad spark knock. And today the same thing only from 2nd to 3rd gear WOT Same weird noise wondering if you guys had any ideas. Thanks!

Edit: Also My buddy has scanned my car for Kr and I had none

Uhh supporting mods for the 3.4? Everyone knows what happens when you run an overdrive pulley without other supporting mods.

How do you know your car is low on compression?

Compression test

Well the loss of compression could be a chipped piston. The noise could be a chipped piston. Those few mods on that pulley could result in a chipped piston.

Sir have you not realized your car is possessed by demons. I figured you would realized 3 or however many motors ago.

If it was a chipped piston wouldn't I be hearing the noise constantly not right after it shifted? And since I have no Kr* wouldn't that mean I have sufficient mods? Not trying to sound like an ass just new to this stuff trying to learn

How would adding more boost help lost compression in a cylinder?

Do you understand how an engine works?




How are you seeing that you have no KR anyway, though that question is mute because how this thread as gone.
