It's a blue 2002 jetta, 11 mm pump with 12 mm head, propane injection, hybrid vnt 17, FMIC, running 35 psi. Obviously it has head studs and aftermarket pistons.

Speaking of power, the most recent dyno numbers indicate 31 hp and 493 lb-ft of torque at the front wheels

only 31 hp!!! Wow, I knew that TDIs make more torque than horsepower, but what a typo!

Hehe, I am thinking that it's 231 hp. Maybe 310?

High 14 seconds isn't very good for that amount of modification though. 43 mpg is pretty good but he's already busted an engine! Makes any cost savings not add up.

Well it supposedly makes 318 hp according to : http://forums.vwvortex.com/zerothread?id=3589239

That seems too high, 231hp seems more reasonable with the mods listed....but

Well, I don't know what a VNT-17 or any VNT turbo for that matter is capable of boost-wise, but 35psi is nothing extraordinary for a highly modified diesel. My neighbor has a Cummins dodge with twin compound turbos and it will easily push 75-80 psi. He uses an oil pressure gauge for boost since no boost gauges go that high. And in the tractor pulling world, boost pressures nearing 200psi are not unheard of. Those guys dump an insane amount of water/meth into the intake to keep temps down.

Anyway, if this guy is spraying enough nitrous in this Jetta, it doesn't really matter what turbo is on it other than possibly from an exhaust restriction standpoint. Nitrous and turbocharging are both forms of artificial aspiration.

Wow, great job! Although I don't think I would want to blow my engine!

200 psi???

How can it withstand the pressure?

Is 35 psi a lot?
