supercharger spuddering at boost

[duffmanoyea]

after i get on it the car around 11 psi to 14 psi the super charger has like a spudder sound to it, my mods are cat back exhaust,cold air intake, 2.80 supercharger puller, diablo tuner and heat exchanger, now my brothers lighting did the same thing but worse and it ended up being coil, think its time to upgrade my ignition?

If you mean the engine starts to studer maybe its spark blowout?

If the blower sounds like its sputtering check the bypass valve, if the engine is acting up I agree check coils and plugs.

it sound like the supercharger the wine is like a spudder when at higher boost my brother lighting did it really bad and he had a bad coil. im thinking new plugs a coils

 

[duffmanoyea]
