      Sounds good to me. I'm working on a set of cams right now. When I get back and start test and tune for them I can kick you my data sheets if they help any.

      That would be nice. Any additional information couldn't hurt.

      arent there any issues? i was told that the crank on the 2.5 is on the heavy side, so at high RPMs it creates a lag cause of the rotating mass.

      The valve spring requirements increase exponentially- you need a hell of a lot more spring for 10k, then 9k for example.

      FWIW, the FSI springs are a cheap "junkyard" upgrade, not that you care. Interesting tidbit though.

      I don't doubt that at all, coming from a sprint car backround and working a lot with big block and small block applications I am very aware of what it can take to make a high revving engine and trust me you guys will be getting a call from me about the valvetrain components.

      just wondering... why not INA?
      they are forum sponsors, and my experience with them has been nothing but incredible.

      for issam.

      We are trying to work with INA on some parts as well but so far we have never had any luck.

      Im gonna suggest that if you plan on NASA and what ever endurance events that you use a AWIC.

      Along with the front mount setup we are also working on an awic setup.

      The parts for the AWD swap should be here next week and the drivetrain should be here from the UK in another 2 weeks.

      When do you guys plan on dynoing your NA setup? Im anxious to see how much power can be made with all those parts since thats most likely the direction Ill be going with my car.

      We are planning on dynoing the car before it gets torn apart but for now we are tearing apart the interior and removing all sorts of weight. I will post a pic soon of the parts that were removed but for now we removed an additional 200lbs today and we expect to be able to remove an additional 200 tomorrow which will bring the cars total weight according to the corner balance scales to around 2500lbs.

      That's awesome.
      I excited to see how gutted the car needs be to reach that weight.
      Our cars would feel a lot quicker if they weren't so portly.
      All for safety, so I suppose it's ok.

      In for the details of what 400lbs was removed.

      Yeah that is ALOT of weight to remove from that car. Id like to know what all came out of it, Im assuming the entire interior except the stuff that needs to stay.

      Yeah pretty much the entire interior except for the dash. We have removed a total of 260lbs in the interior but of course the cage weighs about 120lbs. The extra weight which hasnt been removed as of yet will be the entire HVAC system, additional wiring, glass (which will be replaced with polycarbonate), Emissions System, A/C Components, and much more. WE are hoping that the car will sit nicely around 2800lbs-2900lbs when it is all said and done with the big turbo and the AWD setup.

    24. 06-30-2011 10:45 AM #49
      2800-2900 awd would be perfect for a race rabbit. The good thing about this build is you can add weights wherever possible to make the car somewhat even at all 4 corners.
      As mentioned above please post your results on the NA setup, I've always been a big fan of the 2.5 and is considering doing an Audi b5 A4quattro with the 2.5 turbocharged in the near future.

    25. 06-30-2011 02:14 PM #50
      Thanks for all of the comments. We are working on getting the car put back together that way we can get it up on the dyno. So far we are at 260lbs of total removed weight. We still though have most of the HVAC system to remove, a couple of airbags, some sheet metal out of the doors, the glass (which will be replaced with lexan), wiring, and other small bits here and there.
