Kingers. Member 227 Member For: 14y 1m 30d Posted 12/11/10 07:58 AM Share Posted 12/11/10 07:58 AM hey guys tonight I noticed a screeching sound coming from the engine and also its was over boosting to around 6 ~ 8 psi will over boost in all gears but only noticed the screech in first and second. Happens if I plant my foot and will start screechin at around 4 ~ 5k. I can rev the car up in neutral and it wont screech. Only happens when foot is flat to the floor. Anyone know what the problem is or could be?? Car drives fine in all other areas. No power lose or anything like that. Car is a bf mkii only mods are a k&n air filter and center muffler removed over a month ago. Link to comment Share on other sites More sharing options...

Checked to make sure all your hoses and that are tight? Manual I'm guessing?What sort of screech (I know, silly question) pulley/band? Or metal/metallic sounding?

Mine maxes a bit of screeching noise high up in the rpm because it's maxed out. Link to comment Share on other sites More sharing options...

Its like a high pitched metalic sound. I know it shouldnt be over boosting with whats on there it only happened today, so somethin musnt be right somewhere :(had a quick look at the pipes and all seem fine but will have a closer look tomorrow. Yeah its a manual Edited 12/11/10 08:36 AM by Kingers. Link to comment Share on other sites More sharing options...
sexual harrassment panda I see a red door and I want to paint it black Donating Members 5,919 Member For: 14y 5m 25d Gender: Male Location: Far north queensland Posted 12/11/10 08:38 AM Share Posted 12/11/10 08:38 AM screeching sound from overboosting in first and second you say, but doesn't screech in the higher gears. Pretty sure I know the culprit for this one. Please check your rear wheel arches for a crumbly layer of a black sticky substance. Link to comment Share on other sites More sharing options...
