I HAVE AN 03 COBRA, AND WAS RUNNING FINE....THEN YESTERDAY, IT SEEMS THE CAR IS NOT ACCELERATING LIKE IT SHOULD.....AS I FIRST APPLY THE GAS, I CAN HEAR A LOUD WHINE, THEN ILL PRESS IT MORE, IT WILL GO AWAY, AND I WILL HEAR THE NORMAL WHINE FROM SUPERCHARGER, IS MY BELT SLIPPING???? IF SO, HOW DO I FIX IT? I NEED HELP ASAP......ALSO, HAD NEW CLUTCH PUT IN YESTERDAY ALONG WITH 3.73 GEARS.....NOW IT SEEMS SLOWER WITH THAT LOUD WHINE......IT USED TO ONLY DO IT WHEN I WOULD FIRST START IT UP AND DRIVE FOR A MIN, THEN THE WHINE WENT AWAY.....ITS DEFINATELY 2 DIFF WHINES IM HEARING

...any video clips?? ....Time for the Auxilary Idler Pulley!?

no videos, as soon as i tap the gas, you can hear the whine, even when im at 2500 rpm's just cruising, and then tap the gas.....its a louder when then when i hear the supercharger whine at lets say 4,000 and beyond.....would that be the supercharger belt pulley slipping? def a loss of power

Timspony

Hard to really tell for sure unless heard....

03cobravenom

what would the auxilary idler pulley affect? and what does a slipping supercharger belt sound make?

MAD SVT

the slipping makes a slight squel if the belt is older, if its new, theres not squel at all, just a loss of power. i had this problem until i put an idler on it and it went away entirely.

an idler puts more tension on the belt, so it cant slip.

theres def a loss of power, it has a gatorback belt on it....does it not come with an aux idler pulley stock? what size would i need?

Timspony

Auxilary pulley can be seen in this pic of my engine bay just below the Eaton SC pulley to the right...Metco 90mm ....makes a big difference!

MAD SVT

heres a Billetflow.. 90mm although i had a 100mm on there prior to the blower swap.
