On my old mk2 I could hit 1200 no problem, but....
I had tons of fuel. I build pumps as well that one would about droun the engine if I wasn't careful. Used injector tips off a CASE backhoe.
Was also running a huge front mount and a hybrid kkk24/26, full 3" turbo back.

Anyway, I ran the ARP's in the first post with a MLS gasket and hit 40psi several times, oftin ran it at 30psi sustained. I detuned that engine quite a bit when I sold it so it would be easier to drive. It's still on the road blowing smoke today...

He actually has it for sale I think.

isnt the 24/26 an agreed upon performance restriction? the hot side being too restrictive for the massive K26 cold scroll?
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

Not that I'm aware of.

Have the 24 hot side machined as I did and your set. 

Drive pressure was about 1.1:1 and less most of the time. So 25psi on the cold side and 30psi on the hot side.

The problem is (at least at my elevation) it takes to damn long to spool for normal driving. I swapped on a 24 when I sold it again so it was easier to drive.

Did you ever run that engine on a dyno or drag strip? How quick would it be, say compared to a good running stock VR?  ;)

enough boost is when you have 3 dimple marks in the hood from the valve cover nuts..  ;D

Even a mildly tuned vr would be seen in the rear view mirror, never tracked it but I did run out up against a couple 318's and several hondas. the only car that ever really challenged me was a really built WRX. We ran out of road and bothh of us have the other thumbs up...
