    If we had entered three 6's for Daytona, at least one would have have been with a bone stock engine at stock power. I wonder what broke? I read at least one was a blowed up engine. Anxious to find our more post mortem if any inside info makes it to the web.

    Aside from their cost I never understood why people race them.

    At this point I'm not going to be too hard on Mazda/Speed Source, they had a lot to get done a short period of time. If by mid season they're still unreliable, then I'll let 'em have it.

    They really did seem to under-perform speed wise. There were several comments about how slow they were on track.

    Did I see an RX-8 in GT?

    As Rob said,at least test the cars for a few hours on the dyno or whatever.They have a track with their name,no excuses here.Slow,unreliable and expensive was just monumental.
    Yes,there was a single RX8 in GT.

    It might have made sense to run a new 6 with an MZR motor, just in case the diesels didn't show well.

    Two of them dropped cylinders. Not sure what happened to the 00.

    I'm sure they did as much testing as they could, but I think the actual engine in the car type of testing is pretty limited these days to keep costs down. Of course, it hurts new development, but that's the way it goes.

    I am sure that going to MRLS(just for example) or even renting BRP for a few days would be much cheaper than putting together a 3 car team for a 24 hour race.And less humiliating.

    The 00 lost a rear main seal I just discovered.

    Wonder why they burn so much fuel relative to both displacement and output? Is this related to their tendency to exhaust a lot of unburned fuel? Regardless, I kind of like their characteristic tailpipe flames.

    The testing limitations are imposed by the series, not the teams. AFAIK, you aren't allowed to test outside the "official" test days. Few pro series these days allow open testing (I'm sure there is one, but it's not Grand-Am, F1, Indycar, NASCAR, WTCC, BTCC, V8 Supercars, or DTM)

    Now, could they have tested the engine in some kind of mule? I don't know ... I am sure that Grand-Am does take a dim view of that kind of thing because it becomes a slippery slope.

    The Mazda and Speed Source engineers had 400 hours of dyno testing but limited track testing. Maybe Speed Source doesn't understand how to properly build piston engines.

    GRAND-AM Hosts Two-Day Open Test At Daytona

    I certainly dont believe that there are many GrandAm teams that could afford extensive testing,except for the Daytona 24.It was mentioned a few times that Ganassi Racing are almost not track or aerodynamic tunel testing.

    During the saturday Grand-Am race at COTA one of the commentators announced that part that was broken on all 3 diesel Mazdas at Daytona 24 was an aftermarket racing part.So,is it official that Skyactivs are made of aftermarket parts

    If it wasn't an aftermarket part then, it sure is now!
