Popping Sound Shifting Under Acceleration

christian370z

Yep, but this happened before I filled with race gas and switched maps too. But the exhaust definitely pops more on race gas, just not as loud and those pops don't sound like it's coming directly from the footwell in the cabin. Thanks for helping, how do you like your Stillen SC btw? I was tempted to get a used kit with the 951 impeller

Yea will pop alot and you will feel it there it is actually travelling thought the exhaust, My buddies old GSX would shoot flames out the back when he shifted at WOT ,

The SC kit is good, Bad seal rigth now. we think car is at the dealer, But I just ordered a upgraded heat exchanger, and looking into swapping the pulleys, But overal I really like it ,412 WHP is pretty good for a AUTO. . See my thread "Starting steps" Cliff has been helping me alot,

Did you mean the 928 Impeller?
