    Speed mod season 2019 has begun!

    Working on getting an update on the website for 2018, but in the meantime Andy did a podcast with EAA.

    Edit: got the website stuff cleared up and updated. Andy's write up for 2018 is here.

    Looks like the new 0401 model turbos.

    I think that wouldn't be searching for micro knots but maximum problems. But considering the day it was sent I have to and say you didn't even fool me once.

    Hah! "model 0401 turbos"

    Searching for more speed always causes more problems.
    Seriously the progression has been: we need more boost, now we need more air to the turbo, now we need more fuel flow, now we can make all this power but we need a new piston design and lots and lots of cooling of cooling to keep up....And so the cycle repeats

    And to prove we really are working on stuff here's some baffling that we're going to test in the next couple weeks.
    This has been on the to-do list since the gold race.
    If you go back and watch laps 1 and 2 again, you'll notice Andy's right hand quickly go to the SDS panel. The SDS enables him to program fuel flow levels for each cylinder, and #6 temps started to run away. The air comes into the plenum so fast it doesn't have time to slow down (despite our best plenum efforts) and ends up "jumping" over the first cylinders. We had already put a similar baffle on #5 in VA, which had previously been the hottest cylinder during test runs.

    Good grief those turbos must generate a crazy amount of heat. It's a science unto itself how that heat is managed. Thank you CubersWrist for the updates.

    Been negligent about this. This is our latest integration project...
