I would try blocking off the wastegate on the k14 and running a large external wg to bypass the k14 at higher flows. It seems that lately the people who have been getting the extreme power figures lately and even 935's black widow engine all had very aggressively ported exhausts and haven't really had head issues. :?:

What are the differences between the hx and hy holsets?

That sounds like a very good option

The HY35 has a small 9cm exhaust housing. I'm unsure what size the HX is but it's much larger especially if you consider in the 1.6 liters of air we are displacing compared to the 5.9 liters it's designed for.

dont know the specs but in portugal is very usual prepared tdi´s run more than 200hp.
they street race them all the time and they seems to hold many km at full rpm without many issues.at least that is known.

yes, also in Poland there are many tdis over 200hp... but 300hp is not this same as 200hp

well, check the you tube for videos in the ponte vasco da gama and you will see that they move good as well :twisted:
+300 is not the same as 200 but there is more and more going over that 300 mark :shock:

I think you would have better luck with the HY35 over the HX.

I like your thinking though.

Been thinking a small set of compounds would be better.

Like a k14 over a k27 or T3/t4 equivalent. Fast spooling of the 14 combined with the flow of the 27.

The k14 and the merc 3 litre diesel T3 would work very well I think.I ran the k14 with the hx30w and it worked well too.

The k14 wastegate is big enough even for small compounds.The k14 is small so I could run it to the point where the wastegate was fully open and it still just kept the turbo spinning where it need to be.A big wastegate or bypass valve is only neccesary for a sequential setup where the bigger turbo takes over from the small one.

The hy35 turbine (9cm) is plenty big enough our engines the hx35 turbine at (12cm) is way too big even for compound.The hx30 has a 6cm housing.keep in mind that each of the corresponding turbine housings are matched with a turbine wheel that flows accordingly :wink:

I can't get the pic links to work? I wanted to study the pics again. Does anyone have them saved?
