My 5.3 dynoed 445rwhp on 6psi with the LS9 cam. No dyno numbers before but it probably was not impressive lol. I could see 150hp from a cammed 6.0 on 5psi.

 

Nice " after" !!!!!! Congrats!!!!!

Wheres the whistle at though????

 

Nice!!!!

 

Thats only 30hp per pound. Thats not hard to see with an efficient turbo on a good flowing engine. Your first video looks fairly close to how slow my **** is, gives me hope that a cam and some FI will get me closer to where I want to be.

 

I wish mine ran like the first video.

 

Yea.
Im not even close to pushin the turbo so its not gonna whistle yet.
Plus pullin air from the stock airbox kills the sounds im sure.
I can hear it start whistlin bout 2000-2500 but above that the other noises take over.

 

Oh that first one was shiftin at 6700
I just had to try it and see what it did.
Power fell off fast

 

pretty much took off 5 seconds 0-100
