    Just got off the phone with with Diablo Sport...

    All the Diablos have limited authority. I think only 5% fuel and 2% timing - not a lot you can tune with on a modified engine.

    What's the deal with the revs?

    I did use defrost this morning - causing the A/C compressor to run. Closed loop idle picked up the RPM like normal.

    What's the deal with the revs?

    This is my first modular motor. I've had 3 LS motors since '98 - none of them did the idle hangup thing. I did drive a BMW last year that had worse RPM hangup between shifts than the Mustang. Back to the fix! Cold start fast idle works fine with the 5/16 inch orfice. The car noses over right...

    What's the deal with the revs?

    OK - this is what I have done, so far. I removed the entire IAC air supply hose assembly from the engine (hose from the intake duct, the little plenum, and the hose to the IAC). I then pulled the IAC side hose off the plenum. I pushed a 1/2 inch long piece of 3/4 inch OD hose midway into that...

    Winter snow brings GT woes...

    I'm with you! Snow or Ice on Road = Drive Escape.

    What's the deal with the revs?

    And, I assume, implemented through the IAC (an orfice on the inlet to the IAC can limit the airflow).

    F cam

    Rough idle has more to do with overlap - determined by the lobe serperation. Closer lobe sep = rougher idle.

    Are the 4.6's and 5.4's big blocks or small blocks?

    I'm with you! I keep asking why Ford would want 2 different deck height blocks. Seems dumb to me! Different bores or strokes on the same block makes more sense.

    What does pinging sound like?

    I think detonation sounds like shaking a piece of sheet metal. It can happen at higher manifold pressures whether WOT or not - a lot of throttle and low RPM. Air/Fuel ratio is affected by air density. Colder air, higher barometric pressure, or lower relative humidity all contribute to denser...

    What's the deal with the revs?

    I noticed the RPM hangup between shifts right away. I also don't like the freewheeling feeling (lack of engine braking) when decelerating in the lower gears. I have driven other cars that do the same thing. I suspect it is done for emission reasons. True Blue - how big a hole in the copper cap?

    How far will SLP go?

    I saw their display at the Performance Racing Industry trade show at Indianapolis last week. With the demise of the GM F body cars, look for them to do a lot more Mustang stuff.

    timing and dwell question

    You gotta do dwell first. It's really the rotational degrees that the points are CLOSED - when current is flowing through the coil. More dwell equals more coil saturation time. More dwell equals closer (less) point gap. More dwell is better for high RPM operation. The spark occurs when the...

    Supercharged 01 GT or Stock 04 Cobra?

    Like what? The motor comes complete with intake, supercharger, and throttle body.

    Supercharged 01 GT or Stock 04 Cobra?

    Another option you may not have thought of - Ford sells a crate 5.4 supercharged Lightening motor for $6700.

    Air Silencer Removel

    Mine is off - I like the increased intake sound for more PERCEIVED power. A friend with an '03 GT auto has an off idle hesitation with the snorkel off - my 5 speed runs fine.

    Ford Stuff at PRI

    I spent some time at the Ford booth at the Performance Racing Industry trade show at Indianapolis last week. I found it strange that they had very little for the SOHC motors - not even a block or crate motor on display. They were pushing the 5.0 Cammer DOHC 4-valve motor. It was interesting to...

    Programmable Engine Management System

    www.andersonfordmotorsport.com showed a new product at the Performance Racing Industry trade show last week. They have products for EEC-IV Mustangs and EEC-V Fords (all). The system is a piggy-back on the factory computer. It does not require a laptop to do the adjustments. An included control...

    SVT Focus @ PRI

    I just came back from the Performance Racing Industry trade show at Indianapolis. THE most impressive car that I saw there was a Focus SVT - looked like a stock silver car. ATI Motorsposts (www.atimotorsports.com) did a couple of small modifications; a 4 valve supercharged Cobra motor and rear...

    $1,000 down and tune still isn’t right!

    A full power reading that rich with detonation tells me that core temperature (a detonation pre-cursor) was attained some time prior in the accel. I would add fuel earlier in the RPM range. Make sure it's not leaner than 11.5 or 12.0 through peak torque - then lean to 12.7 1000 RPM above peak...
