I was racing my 2000 lightning and after a few passes...I was going down the track and when I hit the gas at full throttle there was a weird machine gun like sound coming from the supercharger. It wasn't giving a solid wine like it normally does. It was spitting and sputtering like a machine gun. Has anyone had this problem before or maybe know what it might be? My only guess is that a gasket might be out, like it's not getting complete compression or pressure and its spitting part of it out. Any information would be a great help. Thanks.

Oh yeah... by the way....I smoked a new 6.0L GTO. Plus I'm completely stock. Those cars suck!! Later.

 

Where you icing the motor down by chance?

 

nope....why do you ask?

 

Myself, and a few others that I know have gotten a coil pack wet when icing down and it run it the same manner as you described. The only other time I have had my truck run like this is when I was getting unmetered air into the intake after the MAF. It would run the same way you describe. Bottom of the intake elbow worked its way off the throttle body. Slid the elbow back on and tightened it down, poor running condition gone when under boost. Just a few ideas, hope you figure it out!

 

Sounds like you blew the head gasket and the drivers side exhaust manifold gasket ( pretty common problem) ....I did the same thing and it sounded like a machine gun under part boost. When it cooled off the truck sounded OK so it resealed on its own. How does your truck sound today ? Did it clear up ? I bet its OK isnt it.

 

Perhaps a plug is getting ready to launch!

 

yeh im with either the plug theory or the gasket

 

It takes a decent driver to get good times out of a T-56 at the track. Those cars are definitely not dogs by any means. They are kind of ugly though. Still a good kill.

 

it shocked the hell outa me and my brother when we killed that gto and it wasnt even close...i didnt get it though...the car was like brand new he even had the temp plates on yet and it was even an auto...i thought it would kill a stock L. but it was still funny! i will try your guy's advice and thanks alot i may get back to you and let you know what we find!
thanks again.

By the way...it seems to still drive fine so we just didnt hammer it at all...is it still alright to drive until the fix?
