I installed my Gatorback belt last Friday, and since then I have noticed a high pitched "whistle". Today I raised the hood, started the engine, and have it narrowed down to the blower snout area. I thought maybe it was being caused by my JLP ramair, but it is coming from the blower snout.

Has anyone else noticed this?

I am not complaining, I kinda like it! Sounds cool...

What pulleys are you using?? Mine has a high pitched whine at idle, kinda like a whistle but I believe its the combination of the tight belt, idlers, and 2.70 upper with a 8# lower....Its a great sound....

 

I am running a 4# lower, and only noticed this particular sound after installing the Gatorback.

 

I think its just the belt, is it more like a high pitched whine??

 

Not a whine, more like a high-pitched whistle. I am 99% sure the sound is NOT coming from the blower iteself.

 

Is it just at idle or can you hear it throughout the RPM band?? Mine whistles/whines at idle but isnt so noticable while driving. I mean it is a definate blower whine while accelarating. But at idle or stop light sounds like a high pitched whine/whistle...


Is the belt the correct length??
Is the belt seated right on all the pulleys??

 

The belt it the correct belt and seated correctly. I only notice the whistle when gently accelerating, like through a parking lot. It is NOT blower whine. Almost sounds like a whistle being created by air flow, but I have pretty much ruled that out.

 

wife's Mach 1 sounded like it had an S/C after we put a gatorback on it, also my '01 Lightning had a whistle with the gatorback belts

 

maybe its kinda like a cog belt setup, air gets trapped under the belt and makes a whistling type noise

 

Rick, I gotta tell you, that sig kicks a$$! I had to do a triple take to finally figure that one out hahaha!

Sounds like it's my belt... makes me like it even more!

 

Do you have an Accufab or Billetflow TB on there??? I only ask because my TB whistles under slight throttle....

 

Nope... stock TB.

 

Then I wouldnt worry about a thing....Sounds like normal Gb belt sound to me.....If it gets louder then worry....

 

Thanks for the help 400HPHD

 

...not a prob!!
