Default Slowly but surely

Slowly but surely the stang is getting some progress. Got a couple things done.

Pro 5.0 shifter
MSD cap and rotor
New tail light
New plugs
Cleaned up the headlights a little with some PlastX. Can't really tell but I'm buying a new complete set of headlights this weekend.

Picsssss

Nice ride.. I notice it the one with-out the Mass air flow meter. A good thing for need to speed...

That baby would look Great with a set of cobra rims and wheel. The car also look very clean. I bet it has No rust....

Mustang is a BAD boy in my book....and that's a good thing. Plus t-top is a hard find.

Nice.. the shifter upgrade is always a must!

an MAF would be nice in that car. its a wicked car... some cobra rims would make that car look bad ass.... are you gunna supercharge it? when you get the money of coarse... and what about exhaust

I'm keeping it speed density. Mass air would be better for cam upgrades and such but I wanna be a little different. There were less than 1000 t-top cars made in 88 so I got a rare one lol. My exhaust includes shorty headers, h-pipe with no cats, and MAC mufflers with no tailpipes

For now I'm keeping the wheels and I'm gonna put some 245's on the back. Rims are gonna be one of the last upgraes I do before paint lol

MAF is not the best for fast cars. A program fuel and timing curve is always best (speed density). If the car is making under 400hp, a MAF is wise for street and all-weather. This mustang use a MAP sensor instead of a MAF, which reference signal/voltage to the ECM/PCM software. The software is engineer design/written by Pros. A MAP sensor look at air pressure inside the engine. Air pressure will change at different sea level. So the software make the fuel/timing adjustments base on air pressure.
A maf is only use to measure the density of the air (molecule per sq.in). Base on the temp of the outside air. The HOT wire element inside the sensor changes voltage base on the air temp. The ECM will reference the signal/voltage from the MAF to input fuel and timing.
If the air flow is disrupted by making modification to the air stream, such has heavy camshaft and ported intake runner. The MAF will more likely send weak or faulty signal to the ecm. this will cause idling issues, A/F ratio and back-fire. A piston engine should not back fire on rapid deceleration. back fire is a sign of excessive fueling.

Excessive fueling is bad for piston rings. The excessive fuel, when it enter the cylinder. The fuel will wash the oil/lube off the cylinder walls and burn causing a blue smoke at the tail pipe. the washing away of the oil on the cylinder walls will increase piston ring wear and tear, which bring us to another problem....BLOW BY....the death of most engine. BLOW-BY will cause cylinder pressure to drop. Weak cylinder pressure will cause massive lose of HP.

Fuel and timing is what makes or breaks a engine...and the pros always knows what best.
If you look at most of the Hi-HP computer engine control race car you will notice NO MAF. more in favor for the peed density.

Here is a nice PUMP GASOLINE 93oct, flexing it massive muscle....


Wheelie baby.....All motor too

yea and its nice anyway... so if i were to get a mustang and i wanted to own someone when drag racing i would rather have a MAP than a MAF?

If you're putting down enough power, a little thing like that isn't gonna change the outcome.

A MAF is more fuel friendly (ECONOMY) , because the air/fuel ratio always try to stay around the 14.7:1 ratio most of the time. You can change the air/fuel ratio by using a MAF translator, but this is not a smart move if you start making hi-hp (400+hp).

Here is the reason why i am trying to steer you away from MAF. If you have a hi dollar motor ($10,000). you will hate to hurt the motor because of MAF issue. In my yrs of build fast car. I have experience many problem with MAF. sometime the HOT wire element will get damage. if this should happen during racing....You will detonate/blow the engine due to faulty fuel consumption.

Another thing. You do not want to run a MAF on a turbocharge or supercharge car with high boost. The SUCTION of air from the turbo compressor fan will create enough force to break the hot wire element.

I always use a climate scanner to record current air quality and condition. With a SPEED DENSITY you can enter all the data into the ECM/PCM software base on weather condition. You will need a climate scanner if you plan on running 800+hp and want consistent time run (bracket race). Once you know your sea level, humidity, and air temp. You have all the data to match you fuel requirement. The cell number in the Block learn can be change to rich en or lean out fuel during the RUN. The BEST part about speed density is, you can custom tune all the way through the power curve, by change fuel to quench detention at certain rpm, instead of running a rich mixture all the way through the run. Speed density required experience from the tuner. If you can tune a carb engine you will have a better understanding tuning speed density. You can also you a EGT or wide band O2. This EGT (exhaust gas temperature) probe, will record the exhaust gas burn RATE/temperture.

Just like a gas welding touch. if you had more oxygen to the welding gas. the flame will burn/cut/melt the metal. If you add less oxygen. the flame will burn at a lower rate, leaving a lot of black carbon after the flame is burn. Look at most of the so-call IMPORT racer. You will notice the awful Black carbon build up on the muffler tips. The EGT will let you fine a median in the burn rate. once you fine a median burn rate, then you can play around with the fuel and timing for best HP and 1/4 miles runs.

Speed density is a MUST in winning race.

An little more on this MAP/MAF topic.

The speed density also require a IAT (intake air temp) sensor like some MAF system. This sensor control ign timing base on air temp entering the motor.

Some import use a DOOR type maf sensor. Toyota use this type of sensor on the straight 6 cylinder engine. This type of maf is a NO,NO, for racing. The air flowing into the engine has to move the MAF sensor door. The open of the MAF door will determine fuel consumption. This is the worst type MAF sensor if you are looking for performance. The HOT wire ELEMENT is 10 time better than the door type maf..
