    As you’re considering options, may not hurt to talk to Bruce at Modern Driveline. In addition to complete Tremec kits, they have a house brand of clutches/flywheels with many different options. I believe it’s the “Superior” branded clutches on... (see full post)

    From my experience on track, you're hitting those high oil temps a lot faster than I am, even on hot days with the AC on. So, using my Dark Horse as a baseline, there's room for improvement.Keep track of OAT while doing this, since that has a... (see full post)

    It's really about creating a pressure differential between underwood and above the hood, but I think we're saying the same thing. The gurney I agree should help with that. I do think there should be improved airflow out of the hood vs. the small... (see full post)

    Another avenue to look at is opening up the fender liner vents for the oil and trans coolers. Even on the 350/500's they seem small and restrictive compared to my wife's C8.example here (see full post)

    If you have not already, you will want to make the door hinges pinned for quick removal. Makes trailer loading, maintenance etc easier. Most gt* doors are. I'd consider moving components inside the cage/tub just for crash survivability. You... (see full post)

    Coming from my DIY vacuum forming experience, I would agree that some draft angle on the pocket walls and larger, softer, fillet angles on the inset door pocket edge would make your life easier when it comes to layup and mold separation. (see full post)

    Absolutely love where you are going with this.As another who plays with 2d cad all day, 3d design does my head in. I haven't got my brain thinking in the right process path. Anyway, you wanted feedback. Your initial design looks very similar to... (see full post)

    So for the last couple years I've been dreaming of a carbon door solution for the S550 chassis. And I mean a real race car carbon door - with integrated window frame so you can have a removable lexan window and a functional, but finished door...

  • The race car has all sorts of cooler ducting on the underside which feeds the exhaust and they have about a 1/2" gurney. It can't be smooth. I has to hurt flow to work.I'm not sure about the GTD street car. (see full post)

    So for me, it took about 1-2 laps before my (inferred) oil temp was reading 275+. After that I had to keep one eye on the temps and go less than full throttle. Agree with the 10R80, it looks like this will be my next battle. I think an additional... (see full post)

    So far I've been keeping everything in class for Tuner in SCCA Time Attack - next year who knows. I'm weighing Gridlife or NASA depending on schedules and what I can make. But definitely agree - unless I tear down to the frame I'm not trying to... (see full post)

    I use a Motive Products pressure bleeder and two liters of brake fluid. It's a little slow because I don't pump up the pressure too high, maybe 13 psi. I've been thinking about adding a more positive retention clamping thing so I can boost the... (see full post)

    Here's a few pictures, I got it installed yesterday. I thought about adding a Gurney flap in front of the vents, and that may be necessary. The pictures don't show it well, but there is a lip just ahead of the vents. Running my hand over it, I... (see full post)

  • I wonder how, I want to flush the brake/clutch fluid so planning to take to ford as they have the easy hook up to flush and replace in one set up? How do you do it ALL at your garage, I also have a quick jack I use all the time? Thanks (see full post)

    No Champale, I hadn't even pondered that. I'll find some reading on it here. But I've been eyeing the Magnum for so long.....and the swap is plug-n-play mostly with a well curated parts list that's been 1000x. Those kinds of solutions usually... (see full post)

    Yikes, I guess it's really been 10 months since I've posted here! For a long time I just haven't been putting in the time, and the longer this goes on, the harder it is to adjust my time and re-focus, but I've made some more progress lately. I... (see full post)

  • Can you post some pictures? You'll probably want to run some gurneys ahead of the openings to help the extraction. Having the open holes don't mean much if there's nothing to spoil the air going over it. (see full post)

  • The GT4 is a paddleshift Holinger box, No? That should be a 50 hour box, minimum, if you change the oil between events. The DH is a different story. (see full post)
