Has anyone found the WH1C, and the stage IV kit to be a decent combo to support 400HP, with reasonable EGT's and smoke? I think by now most the gurus now know my intentions, im hunting down the 400HP mark w/o drugs. As some of u know, I need a compressor housing because of the whole flange issue, BUT, do I save my pennies for an HTT stage IV, or a whole nother turbo. I was thinking schwitzer S300, or a B1 or something. One I manage the 400 mark, its kind of all out warfare. I want to make a road map for the future of 1st gen hotrodders. once that is accomplished, Its full on twins, headstuds, firerings, NOS, Pane, EDM's. Its my drag/show truck.

 

A WH1C and Stage 4 won't support that much HP. Its too restrictive. I would say 350hp on #2 would be getting really toasty on EGT's. You'll need an S300 or B-1 etc.. something with a 4" turbo outlet.

 

I running a H1C/stage IV under a hard pull I saw 1600 and got out of it. I don't know for sure what I am doing for horesepower but will know June 30th.

When the truck is empty I can still hit 1400 now that I have properly shimmed the AFC pin.

 

It won't be big enough for 400 HP.

 

OK, I kind of thought perhaps not. So, at this point, obviously i am not fueled enough for twins, but whats it going to take in the respects of fueling enhancement to need a second turbo? I can get my hands on HX-50 and 55's all day long. I really dont want to get into massive dollar amounts to drop one turbo for another, to run a good single, but when a bottom turbo arrives, I could run the original top turbo. Get that?
I dont want to buy another turbo to run a single for a temp bandaid when the W will serve as a top turbo in twins. Whew!

At what point do I need to think about a second turbo? Well I suppose EGT's will answer that question for me in due time. ok so I answered my own question.

OK, for those who know, or have experience with this route, whats the biggest injector suitable or have ran with OK EGT's on the WH1C or the like on our trucks? (obviously with anything bigger, a different turbo or on the harry edge of needing twins)

 

You can run pretty much any injector if you're willing to turn the pump down.

 

HMMMM....... but will I loose the power im running, if I have to detune the pump, but have the same or better power to run some hot injectors thats no biggie. that'd acctually be quite nice, then I would have lots of room to play at the track.
