i've got a question.. after 5500 im running 0 boost.. but from 0 to 5500 i have 17psi and then after 5500 0 psi

i've gotten this since i put my ZZP 3" header and DP and its been doing it since then

and when i get into boost since i got all my mods the supercharger kinda jumps on and off very quickly after 5500rpm

Denny told me to try this boost bypass mod to see if its not the internal wastegate in the SC to be sure that might just be the problem or it might be something in the tune turned on and my tuner cant see it..

Thanks

It goes straight to 0? Do you notice the whine of teh supercharger going away? DO you notice power loss?

Any funny noises?

 

well i hear the SC going on and off very very quickly.. but power loss i cant.. i'm already going fast but not to see me slowing dont.. like i've done 13.72 on the 1/4 miles with this thing going on andthe srt-4 came running beside me after me 2nd gear.. so i guess i cant see the power going away if i'm beside someone

in HP Tuners after 5500 it goes from 17psi to -3 ( Vac ) to 1psi then -3 then 1psi all the time..very very quickly like the SC sound is doing

for funny noise on idle the supercharger clacks.. like if almost the rotors would touch themself

 

I was thinking belt slip issues, but i dont thik thats the problem.

Clacking could be a coupler.. and when its being over spun (not that your doing it with a small pulley, but because its already worn) its not doing its job right.

They describe the sound as marbles.

 

that was my first thought switching the couplers for the ZZP's so i guess that the only solution to my problem.. swapping the couplers and regain my boost after 5500rpm..?

 

any other suggestion guys..?
