    That is an odd question. How hot is to hot... hmmm. Well, 1100 would be. The gurus say shoot for 400 to 500 ish. BUT, you can't be to lean or it will leave like a POS in a drag application anyway.
    What you got goin on?

    Well fired it off yesterday and according to the valli racing egt gauge it was running about 850. How accurate are those gauges?

    you are in the ballpark

    Horsepower determines how fast you hit the wall. Torque determines the size of the hole you make.

    I am no expert by any means. I got my info from this thread on insidetopalcohol.com. www.insidetopalcohol.com - Tuning Port and Hat Nozzles

    I started it for info. Page 2 (should be the link) Mike Cantor gives information. I honestly do not know one way or the other. Cantor seems to really know his stuff, though. I'm not slammin anyone. I was trying to get a handle on my setup.

    If I'm gonna error one way or the other I would rather be fat. It's not a race boat just for the lake.

    Alcohol is for drinking. Thats everything I know about alky.

    If your idling it on the trailer, odds are your going to find out its undrivable, or at the very least does take the throttle well. Alky MFI systems tend to need a fairly rich idle to take a throttle hit without stumbing.

    After looking at my dyno sheets the egt at 4000 is about 1000. Drops to 900 or so at 5100 and jumps back up to 1150
    At 6800. Kinda makes me wonder how accurate that valli racing gauge is
