The TL Diet Videos

Welcome to the "The TL Diet Videos". I will be adding more videos to this thread as the encounters occur. I will try to label each video as "No Race", "Partial Race", "Clean Race", etc, to quickly set your expectations before viewing. Here is one to get us rolling.

NO RACE

The Mustang obviously refused to race.

http://www.youtube.com/watch?v=UBLia...layer_embedded





I tried to entice him into the race by getting into the left lane after making that turn at the red light. I just slowly accelerated like a grandma until he rounded the turn too. I kept a close eye on him. He made a move to speed-up past me. He wanted to get past me (viewing me as a troublemaker) but obviously not to race as I later discovered.

Because of my camera getting the wrong exposure, you can barely see him in my rear-door window in the video (at 0:47). Below is a picture showing him at my rear door.



Please notice that this road is going uphill. It is interesting when racing uphill. The race and your "pull" on the other car occurs in slow motion than it would be on a level surface.

I suppose the Mustang heard and smelled those precat deletes and rolled-up his windows and shift into high gear quick. :surrender ...LOL !! joking

well because like you said, it was uphill, not a flat road. and if he would of got on it, then we would be able to tell how much of a difference the TL diet is vs the gt500. i know my tl-s vs gt500 was BAD. started at a 10mph roll, i jumped out barely, but then when he got traction he smoked me

u did a pretty damn good job of holding the camera good while driving lol.

i cant wait for some real races

greco9885,

Thanks for explainig. The video is just for fun. Like having you ride along with me. Except in this case, you weigh just 1-1/2 pounds. Virtual passengers add no weight you know.

Hope to have some better videos soon.

Just from seeing the driver very briefly thru my rearview mirror, I would guess he was in the high 40's or low 50's.

But, that doesn't mean that those old farts don't know how to floor-it when provoked.

If you look at the drivers of most high hp cars($) during rush hour, they all are older dudes in their mid-life crisis (at least around Houston).

Now, what does all of that say about me?

I see a lot of older guys up here in Z06's that won't drive faster than 60 on the highway.. It's always the Prius owners that try to zig zag through traffic..

I'm amazed at your static weight.. bravo

Innacurate, roughly how much weight have I shaved off with the catback, J pipe, race pipe, pulley and CAI? I'm guessing 40 lbs?

Your car sounds SICK man! You really took off there too. The way you were pulling through the gears shocked me in the 5AT . How much weight reduction would you say you have done altogether? I know you've mentioned it before but I forget

That coiled cord for your Passport is HEAVY. You need to hardwire with a phone cord.

Static weight is "weight on a scale". Dynamic weight takes into consideration if it rotates, such as a crankshaft or wheel. A reduction in rotating weight (for example, lighter wheels) has an increased effect on acceleration/braking as compared to an equal reduction in static (non rotating) weight.

Let's use lightweight wheels as an example. You have the weight reduction of the wheels themselves, such as weighing them on a scale. But in addition to that, the engine has a much easier time trying to get the wheels to spin (referred to a the flywheel effect).

Because it is easier for the engine to spin the wheels, this will free-up some HP. You gained that extra HP from the lighter rotating weight. So now, we must ask the following question. How much non-rotating weight reduction would had been needed to equal that same performance gain from that hp?

In my case with my lighter wheels (rims and tires), the scale shows that I reduced 62 lbs. But the improvement in the actual performance is the same as if I had removed 186 lbs of non-rotating weight. So, that weight reduction was 62 lbs Static and 186 lbs Dynamic.

Which number should we be concerned with? If this was a contest to see which car was lighter, then only the static weight would apply. If this is a contest to see which car can accelerate/brake better, then only the dynamic weight reduction applies.

The dynamic weight can only be used as a comparison tool against a reference point. You could *not* say to someone that your car has a Dynamic weight of 2748 lb. You can only state that your car weighs 2970 lbs (static).

You can say that your car has gained a performance improvement equal to removing 832 lbs (dynamic) from the car, although the scale shows you only removed 610 lbs (static).

So for me to describe my performance improvements that were gained from the weight reduction, I need to use the dynamic weight reduction. Remember that I said that dynamic can only be used for comparison. So, compared to my oem TL, my "TL Diet" car will brake/accelerate as if I had removed 832 lbs (dynamic) from the car.

In post #11, I stated the wrong numbers. I was looking at my notes that were out-of-date. Here is the correct info.


ESTIMATED WEIGHT

2970 Lbs. Static

Question on this:

Since the engine only drives two wheels (via the transmission), can you still claim "dynamic weight reduction" for the rear wheels, or should the dynamic change be only for the two fronts?

I realize you've reduced rotating mass on all 4 wheels, but only tow of those wheels are rotated by the drivetrain. The other 2 (rears) just spin freely.



Oh!! And if an airplane were on a treadmill .... ?

Even though you can't see much in the video I can tell it goes through the gears about twice as fast as mine. That thing has got to be fast. Keep the videos coming.

It still has to accelerate the rear wheels so removing mass from the rear will have the same effect. Maybe it's time to take the dremel to my stock rims lol.

It applies to all four wheels equally. Because all four wheels must increase their rotational speed (RPM) equally, all four wheels benefit equally from the performance gain of the reduced rotating mass.

It has nothing what-so-ever to do with if the wheel is a "driving wheel" (applying power to the ground). It is only the “flywheel effect” that matters, and all four wheels experience the same “flywheel effect”.

A brief definition of "flywheel effect" is rotating objects tend to resist acceleration and deceleration. The heavier that the rotating object is, the more it will resist any change in it's RPM (revolutions per minute).

To learn more on this topic, a person can Google these terms: "Angular Momentum" & "Polar Moment of Inertia"

Great insight.

I've explained this to some of the guys and some say they get it, but I don't think most do. The first mod I ever did was put some light weight wheels and tires on. With no other mods I ran 14.7s the first time at the track. I had the 2nd quickest time and beat the guys with headers and or CAI. I dropped over 9lbs per tire/wheel.

You need to get that thing to the track and get a timeslip. It's definitely the quickest N/A 5AT TL anywhere. Hell, it's probably quicker than a supercharged 5AT. Do you seriously think it's making 250 whp though? I'd guess more like 235, especially without a catback.

I just remembered I saved some info on sprung and unsprung weight. It really helps one to understand what is what and the effect has on it.

{{ Weight is the enemy of performance vehicles. As your vehicle tries to accelerate, negotiate a turn or simply drive over uneven pavement, the vehicle’s weight begins to limit its performance. Racers often do what they can to reduce weight by stripping the vehicles interior and replacing heavy steel body pieces with fiberglass or carbon fiber. This effectively reduces the “sprung” mass of a vehicle such as engine, body, interior and anything else supported by the suspension. “Unsprung” mass consists of the shocks, springs, wheels, tires, brakes and other components that move with the suspension. The heavier that “unsprung” mass is, the more force that is exerted on the sprung mass, which affects handling, ride comfort and the vehicle’s overall performance. One of the most effective ways to reduce “unsprung” mass is to reduce the weight of your wheels. }}

BTW, why've you not come to any of the big Texas meets we've had in the DFW area? Probably why I've only made a couple of trips to Austin.

Seriously, it would be great to hook-up . . and we can talk and compare mods.

Oh, the HP estimates seem good to me . . . I've estimated mine to be the equivalent of 320+ at the crank.
