S400 74/74/AR1 / Stock , Twin setup?
 

Hey guys,

Im pretty new to all this AND Im from Sweden,,,
so I hope you understand what Im saying and can take a couple of dumb qestions...

I have a -06 cummins that I use 1/3 for daily driving,1/3 Towing and 1/3 Playing with it/Racing.

Still have the stock turbo on.

Im pretty shure I want twins... and now there is S400 74/74 AR1 ,none wg, for sale that planing to buy,, but then I got some second thoughts...

Will the s400 above be a good turbo under the stocker?
How much psi would I expect?
and Egt´s?

Is there a bettar second turbo alternative?
Or am I almost as good using a single 62 or 64 ?

I will use a smarty and 90-100hp nozzles together with the new turbo(s)

Im aim at 600-700whp.

Im really grateful for all help I can get from you,, Because I aint getting it here in Sweden..

A coworker of mine has a 12valve p-pump dodge, running a S400 and a stock HX35 turbo. He has 3K governor springs, I believe 370 marine injectors, and larger delivery valves. He can hit 65 PSI boost, and EGT's do not exceed 1300F. Honestly, I think he has a pyro issue, but thats all the gauge reads under full load. There is a little info.
