    Some serious work into this one, well thought out built. I especially like the attention to heat shielding everywhere and I might consider some of that in the future. I hear that lots of people manage to kill alternators and such maybe this would be a fix for that just shield the whole thing and everything. Looks like even all of the water pipes are shielded to some degree or another. What type of heat shielding tape is that?

    What TSP system and also whats with the tablet?

      well that's ballsy. I'm handy with a soldering iron and following circuits, I don't know that I would have even tried that but I'm really glad you did! also sketch af that they didn't regulate voltage to your USB devices.. thanks I think I'll order one up then.

      the bpr 7es ngk plugs your running, have you experimented with other temp plugs?
      Murdertalon, Jan 29, 2018

      I actually think it's a neat feature that they have a voltage regulator built in that can take a 12V source. Was a nice find.

      I haven't tried anything beyond the 7es since I started using them back in 1999 :) I try to keep things simple to minimize change... if it ain't broke, don't fix it. I hadn't heard of anyone else saying at these levels colder plugs were a good idea either. I have wondered if I should try something else but I have so much other stuff going on all the time that plugs are way down on the list of things to play with.

      Hey man, can I ask how you came across the widebody designed by Andrew Brilliant? I'm trying to get one myself, what was the cost on that?
      eclipsecrazy1989, Aug 14, 2015
    4. TSiAWD666
      Andrew posted here on tuners that he was selling a handful of replicas like 5 years ago.

      If you want one, it might still be possible. Contact Andrew via Facebook and see.

    What spoiler are you running in your profile picture? Looking to add one on my car and was curious.

      On my car I only run about 10 deg AOA to get the balance, where the recommended max is 14, so it's been enough with everything else to provide the match for the front.
      TSiAWD666, Mar 9, 2015
    3. TSiAWD666
      err get the balance I like

      Got it. Thanks for the info. Like I said, we'll be looking to add a new wing for next season. Getting all the input I can on making a decision on which way to go.
