First off does anyone have the s400 over stocker setup in the denver area. I would love to take a live look at this kit and possibly take a ride to get an idea of the power gains. Also does anyone know the exact stats on the s400. I already know that it has a 74mm compressor wheel but was wondering about wich A/R ratio he is using ect. The reason I ask is I have a friend who has one of these turbos that I can get for a reasonable price and was thinking about seeing if MPI would sell me the kit minus the tubo. I just want to make sure this is the right turbo for the kit first.

 

I know there one guy in CO running that set up and he's in the 11's in the 1/4

 

Whoa thats haulin butt. Do you by chance know if I can get by with stock cp3 and injectors at 5,280 of elevation with these turbos. I guess I should probably just call MPI with these ?'s huh.

 

hes also has flux 5 or 6's.

 

You are about to go down a slippery slope like me. I have been procuring a few goodies, just need to get the time and a little more cash to put it all together. As for your question about the CP3, you will most likely need to upgrade depending on your goals. But most importantly you will need to upgrade to a FASS or an Air Dog fuel system. Where do you live at in Denver.

 

I live in thornton. Roughly I-25 and 136th Ave where did you dyno your truck?

 

Are you serious!??

 

Man for twins, I would think you would want to do fuel at the same time. Atleast some 50tips and a Fass or AD!

 

Thats what i was thinking those are huge stix for those turbos

 

I believe he is running a stage 3 cp3 as well. 11's in a full weight truck at 5300' takes a 725+hp sea level truck!

 

Who is he?

 

You guys are all smoking something, flux 6s are 1000+hp and that sure won't flow through a 9cm housing for long. He is running 3.5s with a stage 3 cp3. Out Of Sight is who your talking about. He ran high 11's with that set up and stock tires.

You can ask him about the rest of it. I don't want be stepping on his tows here.

 

Hopefully he will chime in eventually!

 

The stocker/S400 setup does great at elevation! When I was living in Utah I ran mine with the stock sticks and it was great with aftermarket programming. With stock programming you can still drive around fine, but there is some lag. You definitely don't need injectors to run those turbos though.

 

justutt67 do you have a built trans? If so what kind?
