1,7 is history. Con rod was broken and everything is junk now :?

sad to hear that

I´m still running my Scirocco almost daily. Broke the first 02A at weekend, but other one is coming. Still looking for more hp´s...

1,7 is history. Con rod was broken and everything is junk now :? The best 1/4 mile is 14,5/166kmh now, there could be a little more power than in dyno last year.

 :shock:  thats bad, how much kilometers did you drove with the gt23v?
what will you do now???

i wish you much luck mate!!!

With gt23v ~40kkm max, with that engine ~5-7kkm. 16-20vt gasser would be nice, Vw diesels just cannot handle/make enough power. 240hp at 900kg car is not much :lol:

16-20vt gasser would be nice,

almost all of my "diesel friends" (and me) want turbo gasser as their next project car

[andy2]

Its very hard to make reliable power (200+whp) on the vw diesels IDI or TDI and thats just the kind of challenge I'm still up for :wink: .

[Benjamin]

Well, if a Hbeam forged conrod bent, was this on very high rpm, or how did it happened, was it realy the conrod wich couldnt take the power becouse of the high compression ratio what you need to make it start, or was the problem wrong injection timing or so, just thinking what the cause is...

My friend got an Opel Speedster, 900kg and about +200whp now, including his driving skills, he kill most porsche's at the track, and not only the old one's  :wink:

So how does someone go about getting an iron cylinder head?  :twisted:

[andy2]

Mabye one could cast an iron head and machine it  :wink: .How about an ALH TDI head to be exact with no place for glow plugs  :wink:  :wink:

[gigaz2]

to keep on dreaming: 16v crossflow with central injector location

[MJF]

I know one who is going to try gasser 16 valve head :wink: Tdi though.

[gigaz2]

gasser heads are even more flimsy than diesels, hes doing it for the flow right?

I guess this is all about the maximum pressure inside the chamber

[rallydiesel]

Would a hx35 be alright as the high flow turbo on a compound set-up? I really think the small turbo needs the have an external wastegate to keep the exhaust manifold pressure from flexing the head.

Personally, although I have no proof, I would keep intake ports virtually untouched, precups as well, and port the crap out of the exhaust ports. I'd keep the IP pump less than 10mm. Then a compound could work.

I will do it. Mark my words. Now I have to learn to weld  :roll: .

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.

[rallydiesel]

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?

seat leon with 1.9 tdi 150hp engine:


many more of this kind in portugal and they seem to hold the head :?:
