yea you can say laggy but im used to big cams in these motors where they dont make power till 4k anyways so its roughly the same but im not used to something like this. if this motor is like this, i cant imagine what the larger one would do. maybe ill stay with this motor or lease cubic inch

 

You got to get that AFR in check, I'm really surprised there wasn't a big KR spike in there. I bet if your exhaust wasn't so loud you would have heard some pretty good rattling.

 

once its running right. theres a few cobras that want a piece

 

possibly, i cant hear **** besides the exhaust. thats why i want to quiet it down. didnt htink it would be as loud as it is

 

The 4.8's are LOUD with turbo no muffler. When I took the cats off with only the STS, it was way to loud for me, had to put a muffler after the turbo. Plus that cam probable opens the exhaust valve while there's still some fire in there. In boost, they get quieter, cuz the turbo spinning at high speed brakes up a lot of the sound waves.

 

i wish i could say this thing gets quiet. only time its ever quiet is off. once it gets into boost the exhuast note chages and just gets louder and louder. and it lopes almost as hard as my other motor did which i didnt htink it would with 3* of overlap

 

video!

 

Ya Really.
