      Well considering Anthony Dowd's GTI VR6 (race car) ran 11.7 @ 116 ALL motor, and a few other guys have ran 12's all motor I think your goal may be attainable with a really low weight, and a good 60'. As long as you are serious about it you should get there. Good luck with the project [IMG]http://**********************/smile/emthup.gif[/IMG]

      Correct Dowd's car is not a street car by any means, although I thought he was still 2.8L, not sure. I hope you get there either way.

      Hi guys. This is my car: http://forums.vwvortex.com/zerothread?id=3016729
      I am an amateur drag racer from Bucharest, Romania, Europe.
      Dracula Country ! Well the ideea is that i have this project.
      It's a 1996 Polo Vr6.
      I replaced the old engine with a VR6. I have a 176 hp dyno run.
      I took out everything in the car. Only one seat is left. I don't really know how much it weighs but i guess i got rid of another 50-60kg so i would say about 900kg. What would be best for me... try a turbo setup or a NOS one.
      Can u explain me better how can i do a NOS setup cause i wasnt in contact with this until now.
      Thank u!!

      id like to find out what mine will do at the track this year as well. stock bottom end, all rebuilt though, home p+p head, mk4 gasket, matched manifolds, and a 75shot for now, single nozzle. hopefully going to find a set of wheels i can put the bfgoodrich drag radials on. i wont be running slicks unless i do a quaife.

      the kit came with a 100 & 125 shot jets. i put the 100shot jets in but it was slightly lean. i then put the 125 fuel jet with the 100 shot nitrous jet and it was much better. it made 273whp and 306wtq.

      with my single fogger dry kit i ran a 12.90 @ 106 spraying right off the line.
      i only ever made one pass with this setup, i took it easy on that pass.. i figured i'd spray it in second gear and see how it go's.
      i ran 12.95@ 111. i think there was potential for a 11 second pass. but i sold the car a month later.

      yea i cant find a direct port setup anywhere, nitrous is going to be fun. i think i can hit low 11's with a built head and 100 shot and slicks.

      all you need is to call nitrous express and they will set you up nice. i thought of going that route, but then found out i would need to be running only 15psi of fuel pressure for proper use, and wasnt looking into setting up a seperate fuel cell just for the nitrous.

      what do you mean by that? you have to have a different pressure for n20?

      thats what ive been told and read, but i dont know how much truth is behind it. im hoping someone else here knows. maybe mint gti knows since hes been down that road before. from the pic, it looks like his fuel line was tapped for the fuel, leading me to believe he went with the route i would have gone

      thats a bunch of BS 6 PSI is for carb applications, I run a direct port on my car and I have it jetted for fuel injection 42 psi, just call what ever manufactor you purchase your kit from tell them how many cyl's what your fuel psi is and what HP gain you want and they will give you the jet sizes

      yeah thats what i thought, well i got my 95 jets in now im going to test n tune a bit on the highway in 3rd gear.

      thats what i figured. a long time ago on this board, a man by the name of Jim, ran a 120shot on is vr, and ran a seperate fuel setup just for the nitrous, and according to him, our fuel pressure was too high for a direct port setup, therefore requiring 15-20psi of pressure instead. like i said, i contacted jon at NX, this is the reply i got so far:
      "Mike, Is this a stock motor and stock fuel system ? How much nitrous are you going to run ? Usually the stock fuel system will support 100 hp of nitrous with a single nozzle or direct port nozzle system. If your fuel system in not big enough you have 2 options 1 up grade your fuel pump or 2 run a separate fuel cell and fuel pump for your nitrous system. If you have any questions, give me a call 1-888-289-6261 "
      so, i shot him an email back about our fuel pressure and if it would be a concern...waiting on a reply.
      who knows, maybe ill go direct port over a single nozzle this year

      just got it now:
      "Mike, I don't think it will be a problem getting the fuel off your fuel rail, and the tune up will on a EFI Fuel Pressure at 60 psi for your motor.

      Jon"
      i know its a bit confusing sounding, but it works ni problem off our fuel lines. the flow is mainly regulated by the fuel fittings we install

      awesome. i always had mine tapped off the main feed line for my single nozzle setup that i have now, but lately ive been tempted to go with a direct port setup. i may do it, and end up using the piranha nozzles since they are smaller and would help with rad support and hood clearance
