    Talking And you all thought it wasn't possible!

    A number of you may remember me mentioning the fact that adding a throttle body to the list of upgrades could be a valuable option. Many said it couldn't be done because our intake is on the other side. Many said there's nothing to be gained. Well... I at least proved the first one wrong! IT DOESN'T MATTER! do you really think Ford would spend the $$$ to redesign that TB? No... They just flipped it! So, with that, I set out to get a Twin 62MM BBK TB on my car. I finally found a new one on eBay for the right price, and it came today. I just got done mounting and test driving it today. A stiffer pedal and a more touchy throttle is the results. As for seat of the pants, I think it's there, and judging by how fast that MPH needle was moving, I think there is some sort of gain here. Do I know for sure? No... Am I going to go on a dyno and find out? Umm... got $125?

    Now, be forewarned... This thing hasn't been on the car long enoph to throw a light or blow up my motor yet (knock on wood...), and like I said, I have no dyno results to see what exactly everything's doing. When I mounted it, I left all the adjustments in their current positions. When I started the car, it reved up and died. I had to adjust the lil screw in a tad before she'd idle again. She idle's great now, and doesn't dip hardly at all when A/C's on, or when I flutter the gas. Everything seems to be going great, so we shall see... Now, on with the pics, eh?

    And my entire intake system:


    The drooling may comence...

    I think the OEM is twin 57mm.

    Bravo, Rick! Keep us posted on the performance gains/fuel economy? I love the sneaky undercover mods.

    Hey Rick...

    I thought you belonged to the "I-won't-mod-my-car-'til-the-warranty's-up" crowd...?



    Anyroad, that mod sounds like a good one, especially for the price...definitely keep us informed with dyno results...

    Okay, I don't hate you anymore, please change my vote on your poll yesterday. IMHO, this kind of tinkering may be where we need to head for that elusive few extra ponies after other mods get done. Glad to know it's basically a bolt on, small tweaking kind of conversion. Thanx for doing the work first.

    When in doubt, GAS IT! This will either fix the problem, or end the suspense.

    on my old lt1 350, the throttle was dual 48 mm while the intake manifold was 52 MM openings. is the intake on our MM 62 mm, or do we need to dremmel it open from the 57mm?

    Larger throttle bodies can render the throttle response more sensitive, or 'digital' as some refer to it. In other words, harder to modulate as with the stocker. This may mislead one into thinking there is more power, but only a dyno/ quarter-mile report will tell the true story.

    Incidentally, it's really hard to 'over throttle' a multi-port fuel injected... there's no mixture velocity to worry about. As long as the intake manifold ports / runners sizes are kept in check, there will be no problem for the injectors atomizing the fuel and mixture velocities being satisfactory, especially since the fuel is atomized so close to the intake port! Not like the old days of over-carbing an engine!

    The Single blade TB's are worth 5-7 and a few ft/lbs on the Lightning... Throttle response is greatly improved though and they look cool.

    Yup, that's the one. Like I said, if anyone can hook me up with a dyno run, I'll be there. Right now, I have zero moola... So far so good!
