    Brake Conversion Progress:

    Hawk Front Pads arrived. OEM Porsche hardware kits and bolts arrived. Front brackets have been cut.

    Still need to have custom SS lines made for the fronts. Still need bolts to hold the brackets to the knuckle. Going to measure them this afternoon. And possibly order if need be. Then they need to be test fitted onto the car. I'm thinking I may have to have the brackets grinded a little for axle clearance. Also looks like I may have to get the wheel spacers afterall. There is less than 5mm total clearance in the front. There is about 3-4mm clearance between the rotor and the knuckle, and maybe 1mm clearance between the caliper and the spokes of the wheel. Needless to say, this is going to be TIGHT!

    The fronts should be done in a couple weeks I'm hoping

    Front kit if you will

    Update: 6-15-2008

    been awhile without updates. The fronts are on and running. I had some clearance problems on the lca, but I just spaced the rotor out further which solved those issues. The rears are pretty far along, but I need to have the brackets shaved a small amount, and we still need to fashion and ebrake cable bracket. More updates/pics hopefully before TotD 08

      <cutting hypers info>
      We mocked the motor to see how far above the deck the pistons would sit, .130" above the deck is what we came up with.

      Head gasket crushed thickness is .050". So the pistons are .080" into the head if left uncut.
      I took down the volume of the head at a conservative 43cc's. To get my compression numbers(my goal is ~11.5:1) I just took my displacement and divided by my desired comp ration of 11.5 - 1. This tells us the volume needed for the combustion chamber. Since we already have 43cc from the head, we subtrack 43 from that number, and that tells us how much volume I needed between the top of the piston and the bottom of the head. Doing some geometry I came up with the following.

      .100" cut = piston protrusion of .030" = 11.64:1 Approx CR
      .110" cut = piston protrusion of .020" = 11.33:1 Approx CR
      .120" cut = piston protrusion of .010" = 11.04:1 Approx CR

      I wouldn't suggest cutting the piston any farther due to lack of material under the top of the piston. Once we get them cut we'll get more accurate measurements of what's left. I also wouldn't suggest cutting any less than .100" off of them. .100" puts the piston .020" from the bottom of the head, and I hear some bad things about running compression too high on pump gas.

      Based on the above data, I decided to go with a .105" cut on the pistons. That leaves me with .025" piston protrusion. Given the .050" HG thickness, I'm left with .025" clearance between the head and the top of the pistons. Hopefully that's plenty for expansion and such. I don't forsee any problems with this.

      BTW, if my calculations are correct, I should end up with approx. 11.5:1 Compression using $100 pistons, not cutting the head any, and not using flat-faced valves. This is also based upon my measurement of 43cc on the head. My head has been ported and polished, so I don't know how much material exactly has been removed, but I wouldn't think it to me much.

        So, how did you take off the needles off the vue cluster without breaking them? Do they come off like the older style clusters?
        I liked my black faces, but I like glowing needles and chrome trim.

          the needles popped right off, they were kinda hard to pry loose though. They were on there pretty good.

            Very interesting stuff on the cutting pistons thing. I'm interested to see how that turns out. Hopefully the thinner tops will hold up to the detonation I'm sure you're going to see until it's tuned in.

              Meh as long as he runs high octane I think he'll be okay. The PCM will just pull timing like a bitch anyway.

              Btw detonation is not the same as knock / "ping"

                welp, as soon as I get it running, we are gonna dial it in on the safc. Hopefully all goes well.

                  how much do you have invested in the brakes all together?

                        it wasn't cheap, but it would have cost a lot more if I hadn't traded two SSBC big brake kits for the work done and lots of the parts.

                          +1 on the porscha breaks! hmm... i doubt i'd find that at a salvage yard. might have to check out the other sections when i go from now one though.
