    Ok, have issues posting. Trying to update yesterdays outing but keep getting bumped off, maybe due to the length of the post. Is there a limit on words/characters.....? Seem to be ok with short post like this......?

    Lets try to break it up into 2 posts...............

    Update from outing yesterday.........<O></O>
    Well..............Glenn (VW-NUT) and I hit the waters yesterday...............<O</O
    <O</O
    Things didn't go to well yesterday. Could it have been worse, hell "YES", but lets just say it's back to the drawing board to deal with air/fuel issue, that's really not a big surprise, I sort of figured it would bite me in the a$$ right from the start.
    <O</O

    <O</OOk, what went down.............Major flat spots right off the trailer, tried numerous things, some helped in one area of the RPM range but failed in others. Seems there was very little to be had in the "Give and Take" senerio. <O</O
    <O</O
    ** With the MAD Intake alone: it was either idle which was good or W.O.T. at 42 psi of fuel, nothing in the middle.<O</O
    <O</O
    ** Upped the fuel pressure to 48 psi and it helped a little, but still very flat in the 1k to 4k RPM range, 5k up it was all out torque.<O></O>
    **The torque was unreal when you put your foot in it and motor was very happy at 5k + rpm<O</O
    <O
    Continued...............
    </O

    So bottom line on just the MAD intake alone, it ran like a true drag motor: Idles in gear: GOOD and WOT torque was unreal, but nothing in the middle......LOL !!!!!<O</O
    Knowingly, the problem with the MAD intake is the sudden rush of air (3 T/Bodies now vs. the 1 OEM w/the down draft). I knew that would be the issue from the git-go so............. I had already made a restrictor plate that mounted onto the front of the intake. I calculated the sq. in. opening of the OEM single T/Body for flow and placed holes in my restrictor plate closely equaling the same sq. in. opening of the OEM T/Body thereby restricting air flow close to OEM single T/Body.
    <O</O

    Results were dramatic to say the least.........so by restricting the air flow it ran much better, idle was still great in gear, faster (1500/1800 rpm) in gear idle was good, then flat from 2000 to2800 rpm, but 3k on up drove like a stocker.<O</O
    <O</O
    So during all this, I was fighting a dead alternator issue as well, so honestly at this point and time I can't condemn anything and my lack of voltage may or may not have played a part in the poor performance. So I'm leaving the setup alone for now until I can find another alternator to verify that electrical's weren't a contributing factor as we did see 11V on my digital voltage gauge and had to listen to the warning horn most of the day stating that motor went in Guardian Mode allot.<O</O
    Had hoped to post up a nice video clip, but frustration set in and all I got was a shorty when Glenn (VW-NUT) and I decided to just take a little cruise and head back to the trailer. I'll try to post it up later today, I will say the if you've got good stereo speakers on your PC, then you'll appreciate the sound at motor start up....it does sound "REAL GOOD"........ Top speed was not the issue for the day as it was all about tuning nothing more. Once it's running much better than we'll move onto the next step, I gotta be able to crawl before I can run on this project. <O</O
    <O</O
    On a positive note, it was still a great day on the water, nobody got hurt, nothing blew up and we didn't need a tow back in to the dock............. Life is good....<O</O

    Thanks Glenn for tagging along yesterday, appreciated the help.....<O</O

    Here's the short clip, if you've got a set of good stereo speakers w/a sub on your PC, you'll like to sound of the motor at the beginning of the clip. The run was with the restrictor plate on. You can here a little flat spot when we launched, but after that it was all good.

    Yeah I know, it kinda defeats the purpose of the intake, but just trying everything I can throw at it........

    I changed it to public and saved it.....don't know why you can't view. Try again and maybe I'll have to delete it and reload it. Let me know.

    I can't get the vid either Gary. Very nice work on the restrictor plate Tip: One hole over each opening instead of three with a real velocity stack. Something like this (built for a KTM 950 FCR setup, so the boss below the bell is for mounting an air filter):

    Whats withe horn going off? Does the ECU take a MAP signal from the intake? Bad signal at some throttle position's?
