what turbo should I go with on a 09 silverado 4.8L. Already have 340rwhp, trying to get the most hp gains possible.

 

What are you doing to get 340 to the wheels, NA?? There is a bit more to it then the most HP possible, hell you can have a dyno queen that makes xxxx hp for the last part of he rpms, or something that pulls hard through out the whole rpm band..

 

Ls6 cam with a mp76. If you wanna bite the bullet PT76GTS... Look up foose on here. 4.8 with that turbo running 10.80's

 

PT88 will make a 1000+rwhp

You said the most HP possible

 

full bolt ons and a tune. Trying find a front mount turbo kit but no luck yet. What you recomend?

 

those numbers I like. But where can I find a good shop in dallas to work on my truck.

 

In a few weeks, you can bring it to me in North Houston.

Don't forget your bag of money jk

 

that is the highest n/a 4.8 # i've seen. what cam and heads you running? i think foose has probably just about maxed out a stock bottom end 4.8 and he is a little over 600rwhp. a mp70 will get you there.

 

how much we talking about?

 

beehive cam and stock heads for now.
