I think we can definitely do a water-injection system for less than $400. And Christian's right, intercooler pipe won't really add much, especially when you consider that the caved-in intercooler end-tank on one side is probably costing a psi or two.

hey danno did you release your intercooler pipes yet? ken

I've currently got a similar setup, minus the MAP kit (need one...) - do you think the Lindsey stage1 intercooler would help flow enough / cool enough to not need a water-injection kit? also, what about using N20 instead of water (in very small ammounts, in order to not lean out)?

Danno, would your water-kit involve putting a tank in the car/trunk? would it be possible to retain the functionality of the windscreen washer system or would it canibalize that?

finally, with what i've got on my car (in my sig, a lot like steve's, but w/ cat bypass, upg. intercooler, and adj. fuel pressure - granted, i think i'd still need better/newer injectors) that I could push closer toward that 300 mark? would I need the MAP kit to reach it?

Ideally / eventually I'd like to be capable of 350-400rwhp (yet typically setup for 300ish, just able to turn up the boost for track days, 1/4mi, etc)...

Danno,
Are you going to have to utilize an electronic boost controller on your 300 rwhp attempt? If so, what features will you be looking for when selecting such a unit from today's market?
Also, what is the efficiency of the K 26/6? At what point does it move out of its efficiency range? You wouldn't have some sort of graphic?

check out Danno's <a href="http://www.gururacing.net/" target="_blank">Guru</a> website. You should find some stock dyno comparisons there that can give you an indication where the k26/6 begins to peeter out.

wow, Danno!

Jon K at Zeil Motorsports had the brittish DTA system on an entirely stock motor w/ stock turbo and injectors that pulled 295 - 300 HP on a dyno. The Internals were lightened, Apexi AVC-R and of course, stand alone management, but stock turbo nonetheless. At this point, the injectors were the limiting factor, he said.

To get that kind of power he had to be running stupid boost.

What's stupid boost? Over 19-20 psi. At that level you can't be running pump gas (91 octane).

Even with good fuel, you're way out of the compressor map.

I'd like to see the dyno (Dynojet SAE corrected).

A realistic number for the stock turbo is 280HP, which is a lot for the small K26 compressor, flowing 390cfm.
