  1. The altezza flywheel is a dual-mass item so won't be suitable for the FWD setup. Earlier gen 3S flywheels work fine - I'm using the same one that was on my gen3 motor and there were no problems fitting it. The best idea is to go for an aftermarket light flywheel such as Cusco or Jun.

    You should be able to shorten the shafts fairly easily, but is this required?

  2. You're almost defnintely right^^

    xsspeed - You're still better off duction from the front of the car as it's the clean, cold air that gives you the advantage. The best way is to do it similar to the earlier BTCC cars, they had a big plenium and a big duct heading to the front of the car that was 5-6" in dia.

  3. Yeah, the facelift Silvertop engines go a lot better because the manifold is nicer, so it would make sense if the throttles were slightly different.

    Brendan from Garage Dori/Niteparts told me that the silvertop throttles are better when I was starting the Beams conversion because they are a better shape:

    I would def use silvertop 42mm throttles, these will flow 280ish hp with standard throttle shafts- so no restriction there really. Much better shape than blacktop with the kidney backs that stall flow.

    .....

    Standard cams & adj cam wheels are a good way to go, will be more forgiving wen it comes to extactor design too. A good friend of mine just made 240hp@wheels with exactly those mods & silvertop throttles!! Power was still going at 9000rpm! The dyno reads a little more than the one I use, but it still works out to about the same power as mine was.

  4. They aren't round. I only noticed it when we were modeling a pattern for the intake manifold flanges and round holes didn't work. Like I say though, its only ever so slightly not round, like 2 circles of the same diameter with the circle centre offset by 1mm or so. I’ll try to grab a picture of my sapre silvertop throttle if I can track it down.

    That's weird... I'm sure mine were perfectly round. We found used a 43mm drill bit and didn't even need to port match the flange.

    It's this one^^

    We should probably start a "Hansen TVR Chat" topic somewhere cause what I've heard he's doing is different to what has been speculated on here... And it's very unlikely he would have spend 1.2mil on 3xblocks - the whole car owes about that much AFAIK.

    /We need more TVR's on OS.
