    Forced Induction High No Levels At E-check

    Correction: Proper three-way catalytic converters take NOx and convert it to oxygen and nitrogen (N2) gas along with the two-way standard of CO to CO2 and HCs to water and CO2. A working converter will reduce NOx although if the engine is producing excessive levels due to high chamber...

    Forced Induction High No Levels At E-check

    Cats and EGR deal with oxides of nitrogen. You said it passed in for the last number of years "set up this way." Is everything the same? Did you make any changes (e.g. delete the EGR) since the last emissions test? Does the car still have the factory midpipe? How far over the limit is your...

    Blower Gauges

    I caught a slipping belt on mine with my boost gauge. Besides, they look undeniably cool in a Speed Of Sound pillar pod :)

    Do Mustang Superchargers Hurt Mustang Engines With A Lot Of Miles?

    A blower increases cylinder pressures and thus increases thrust loads on the pistons and gas loads on the bearings. On a stock-internal engine it's pushing the components beyond what the engineers originally designed them to though not necessarily beyond what the parts will take (the so-called...

    T-45 Question

    OP, how much free play do you have in the clutch pedal? You can actually adjust the pedal play by pulling up on the pedal until it stops. It may require some force to go beyond the normal "up" position. Get your foot underneath the pedal and pull up on it, hard. That will allow the adjuster to...

    Switch To Conventional Oil?

    I run Shell Rotella T6 5W40 (yes, "diesel oil") in my 2010 STI and am tempted to run the stuff in my MGT on its next oil change. If you're burning oil and have cats though, this may not be a good idea as the elevated ZDDP in the Rotella may injure the cats over time... For tired valve guides...

    01 Blown Gt

    Personal opinion: PD/screw, 3.55s, centri, 3.73s. (And yes, I know I have 3.73s but they were installed before the KB and I can't be bothered to open the rear end and futz with them again...)

    Found Spark Plug On Road Help

    Pretty sure that's a weedeater or lawnmower spark plug. You're fine.

    Egr Delete Question

    Yep, though the EGR system is shut off at idle and at WOT so its presence or absence shouldn't reduce maximum output. But EGR reduces peak combustion temperatures and thus allows more spark advance at part throttle which increases efficiency. The PCM makes assumptions about EGR flow (which is...

    Curious: Why are you removing the EGR system?

    Agreed. Everyone should stick to the quotes they find on the web and their opinions and be done with it.

    Need Help! Need Advice For Super Charger On 03 Gt

    Not all cars utilize MAF meters. Speed density cars use throttle angle, RPM, VE tables, barometric pressure, intake air temperature to compute the amount of air entering the cylinders to come up with a BPW. And even with MAF meters, temperature, pressure and density do matter; the meter is...

    Sorry for the misunderstanding. My temps were displayed "25oC" not "250C", the difference being 'o' vs '0'. The former was intended to denote "degrees" as in "degrees C". And yes, the equations require working in Kelvin (where zero Kelvin is equal to -273.15oC). When dealing with gases like...

    The volume of the fenderwell or under the hood doesn't matter. For a given barometric pressure and humidity, temperature will define the density. For a given volume, what must change is mass. Air density is approximated by p = P/RT where p is the density, P is the absolute pressure, R is a...

    Need Help! Need Advice For Super Charger On 03 Gt

    You're not showing the snorkels that virtually all factory inlets have that pull air into those closed boxes from cooler locations such as the fender well or in front of the radiator. Even the GT500 intake is isolated from under-hood air directly by the elastomer seal around the top of the box...

    Interesting. That link shows KB part number F1016 for the 4" tube for 96-04 GT with the OE 80mm MAF. I didn't know they made a 3" version of this intake. As far as I know you can use the OE parts. The intake kit has a flange that bolts right up to the MAF. Just make sure you select the kit for...

    Need Help! Need Advice For Super Charger On 03 Gt

    That's basically my setup though I can't recall if the 3" pulley nets 9psi. That pulley might actually go higher... For mine, 9#s seems very safe. I'm running a KB tune (chip/module on the service port of the PCM) and it's pretty conservative. Never a hint of detonation, nice and fat AFR under...

    Diff Ratio

    In an LSD both wheels are mechanically connected via clutches (cone, plate or otherwise) or through a gear mechanism (Torsen). In any case, if the driveshaft is free to rotate, an LSD car will have both wheels turn in the same direction when one is turned by hand. An open-differential car may or...

    Well, a few have but it was decades ago... Studebaker installed a Paxton on the 1964 Avanti. Kaiser and Ford also had Paxton-equipped option packages I think. But this was quite literally 50 years ago. Nowadays, no one is using centrifugals as original equipment. Though a few OEs are sticking...
