So far, what is the highest recorded dyno sheet for an IDI VW diesel? What is the fastest quarter mile time or trap speed? I'm looking for a bar to keep in sight with my project and just wondering what the IDI Elite are making power wise.

you can do a reliable everyday low 16 second car. 15s or faster is not longer streetable.

Define not streetable.

i was doing low 16s with minimal mods in my car... i think low 15s to mid 14s would probably be do able with the right setup in the right car (a mk1 would be the lightest.) i forget what i ran but it was a 16.2 or a 16.3 and all i have is a gay cone filter, 25psi(stuck wastegate.) increased fueling, and the stock down pipe with a 2 1/4" tt gas exhaust with a resonator and muffler. once i get a 1.9 head, a pp down pipe, an intercooler, a clutch that doesn't slip, and more fueling than last time, i think i should be able to hit high 15's pretty easy. but i might join the over heating leaky and headgasket blowing club haha

my trap speed was 84 mph and i was running out of fuel in 3rd ( i had no pre pump with a 12mm)

So no one has found a way to get around the "blow-a-headgasket" syndrome yet? Even with lowered compreesion(18:1 or so)?

I really would like to go higher than 125-130 whp on a SUMMER daily driver. I have a MB 300td for winter, so I'm not worried about cold starting my 1.6TD. None of the hot rodder tricks work so far( O ringing, Copper head gaskets, Head Studs, reduced compression). Is it boost that causes the leaks or just a natural td power ceiling? If you had more airflow with the same amount of boost, would power go higher or just leads to leaks sooner?

not sure stuill experimenting. i ran 25 psi dail on a td with a very poor intercooler and a pump with the governor mod and the fuel turned way up (it wa sreliable). Now last year i ran 27 psi on a different engine with a ported and polished 1.6 head and a real good intercooler and i couldnt keep it together.

i did a 17sec Gtech-quarter with my fiat T2 1,25bar/18psi.
11mm plunger, Garrett T2, pretty smokey becouse of the feul quantity, lda adjusted (no governermod, alltuogh, i shimmed the intermediate but didnt adjusted the preload from the main spring)
the engine have about 19,2:1, intake exhaust etc was stock
the car weight is about 2000-2100pound (900-950kg) excl passengers.
the intercooler was about 1/2 than the stock (yes, it mean smaller than stock!)

My best with 1.6 is 15.06/150km/h
Best I´ve seen with 1.9 is 13.8/something.

What mods did you do to run a 15.06?
What was done to the 1.9 td that ran a 13.9?

Only dyno I've had done was 161whp 1 year ago The G-tech 2 years ago was 14.88 @ 98mph.I'm making more power now as I can easialy break the tires loose in the rain in fifth,Butt dyno :lol: problem is that while doing so I can see coolant exit between my hood and fender at a good rate.I removed the resivors deflector so I could see whats going on as I'm driving.I have fineally decided to not depend on my car for daily driving due to its reliablety.The copper HG with studs setup is only part of what needs to be done to keep compression in.I'm getting some work done to my head and lowering the CR to 17.5-18:1 and hopefully it will work.No doubt it will make over 200whp when tuned.

That's sweet, andy2!
I really would like to go higher than 125-130 whp on a SUMMER daily driver. I have a MB 300td for winter, so I'm not worried about cold starting my 1.6TD.
One good way to lower compression is the stage 4 head porting by Passenger, which includes deck modification:
http://vwdiesel.net/phpBB/viewtopic.php?t=7680(disclaimer: I don't make any money by his sales.. my head was done by him I couldn't believe the airflow gains). Simply using a thicker headgasket is not efficient. I also strongly recommend getting a 1.9TD head, which has larger prechambers than a 1.6TD head.
Upgrading the intake manifold to have more even airflow across 4 cylinders may reduce the chance of headgasket failure. You'll likely produce more efficient power before the headgasket fails. With the stock intake, if one cylinder has more pressure than the other, you're making inefficient power and the high pressure cylinder is more prone to leaking thru the headgasket.
http://vwdiesel.net/phpBB/viewtopic.php?t=7676 I used a OEM PD130 TDI intake manifold in my TD and while it is a big improvement, it wasn't perfect.
Does anyone know what cylinder PSI is 17:1 - 18:1 compression ratio? My guess is 375 PSI but I'm not sure that's correct.
