i need more air on my truck but im not rich .... iv heard of compuonding the stock with a S400. has anyone tried it or have some thots on it?

 

Yep lots of people have done it and it works good.

Here is a pretty informative thread about the setup Ryan did.

thanx man. im gona try it before i spend 4k on a kit. do you have any idea what kind of boost i will get?

 

Id think 55 to 60 would be a good range

 

thats whati was looking for. got to do head studs too. is that a hard task? no timing bull or any of that is there?

 

Nope no timing cuz we are electronic controlled. And for head studs they are just time consuming to do. You just need to follow the torque sequence and do one at a time and do several torques on them and a hot torgue as well

 

cool. i work in a machine shop so i can handle that. thanx for the info man. im gona go buy me some more air

 

Hell Yeah

 

What are you running for fuel?? hx35/s475 should be good to 550-600hp. maybe a little more. 35/472 will be a little less and offer quicker spool up. should be able to get the s475 and piping for around $1900. Studs will be another $400. Depending on your fueling you'll see anywhere from 55-75psi of boost. I'd also be thinking about oringing the head and getting 110# valve springs. Just remember you need to tune twins after you install them!!

 

iv got a offroad vp-44 thats 275hp and a superchip(i know iknow) the super chip suck but i get so much fuel right now that its blacking out car behind me. i realy dont have the money to do orings.
what do you mean by tuning twins?
