walk away

[Cody Forbes]

I have some input here that might confuse this even more. Jim Green gained something like 20hp (at the wheels, no corrections, on a dynojet) on his MC1'd 90tq when he switched from the MC1 to MC2 cam. The Blau 272 cam made less power and torque than both the MC1 and MC2 cam. I think the 272 had too much overlap for the turbo engine (turbos and overlap don't get along well).

That doesn't say which is "more aggressive", but it is interesting related data. 

I do think that you misread Tony a bit, but I could be wrong. I think the breakdown per Tony was:

1. MC1 is more aggressive than MC2
2. MC2 is the same as NG/NF
3. 272 is the most aggressive of this selection

I have MC1, MC2, and I think an NF cam (it's a 10v non turbo and I wrote the engine code on it, just forget right now). I could measure them up some day and provide empirical data.

      ==============================================

      Tony, 

      does this mean than that:

      1 MC1 cam is more aggressive than MC2 cam, which are both more aggressive than JT cam?

      2 NG/NF cams more aggressive than 272 cams?

      3 Is NG/NF also more aggressive than MC1 and MC2, respectively?

      Sure will.

      First, before doing a cam swap, do a good free flowing exhaust. If not,
      period tests (VW & Porsche) show a slight loss of torque with no gain in HP.
      Those were with the 272 cam, though.

      I have a 2.25" exhaust in mine. The cam swap doesn't seem to have negatively
      affected milage. In fact, I have seen a slight increase, probably 1mpg
      across the board. This is my DD, and I just put over 2500 road trip miles in
      it, so I check milage often. I don't know that there is a rev point that the
      difference is noticed, rather it's just more powerful ar higher RPM's. I am
      also working on a stock 84, and comparing the two, mine is slightly stronger
      from 3000 up. However, the 84 has better base settings, so the off idle is
      better. Mine is identical to when the stock cam was in it.

      The swap is straight forward. I just took the old one out, put the new one
      it. I needed to remove the old one anyhow to clean the lifters. And, I had
      the MC1 cam laying around. I would suggest replacing the WP/TB/idler/cam and
      crank seals when you do this as well. And, replace your VC gasket with the
      rubber one.

      I don't have specs for any of the cams, however. But, I've been told that
      the MC1 is slightly more aggressive, then the MC2 and NG/NF cams (which are
      the same) are even more aggressive. then, the 272 cams.

      HTH,
      Tony

        Dan,

        Just had a friend sell a 740 Turbo Manual with a bad clutch for $300. Pretty nice shape. But, Camden will get a non-turbo, for obvious reasons!! Although, it will be a manual.

        to add to Cody's info, the JT is non-interference, the 20V's all are, as are the NG/NF (100's and 80/90's). However, as I've added teh MC1 cam to one of my JT's it became an intereference engine. It has more lift, therefore interference is certain if the belt goes.

        A majority of newer engines are interference, while a lot of the older ones (not just VAG) were not.

        Tony

          I know first hand that the MC 10vt is interference on all 10 valves.
