Coming up to a traffic light adjacent to an on-ramp to the freeway, I see an F-150 Lightning (maybe a 2001?) with a custom plate that reads (ALLUCIS..something)

I'm thinking, this outta be good....

Guy makes the 90 degree right reeeaaallly slow to the on-ramp like a grandma and then throttles it (prob half throttle), I follow suit. Seeing as I'm right on his rear bumber, he proceeds to bury it at about 50 mph...nice plume of blue smoke comes out of his incredibly LOUD exhaust, he definitely has some serious power under the hood and makes a quick lane shift to the far right lane to avoid a slower car and is speeding away

I take the far left lane gun it with about 14 psi...I'm even with him at the top of 3rd and pulling past in 4th, then he abruptly shuts down at 120, I look over at him and started laughing...he's looking straight ahead, couple of latino guys in the car who look like they work for the mob lol....anyway I put it in 5th and cruise to about 140 (moon roof is open, oops, ha....good thing I'm wearing ear plugs)

he's obviously extremely pissed and cuts through some traffic aggressively to try to catch up, but I end up taking the freeway north and he heads south

the FD is a never ending source of entertainment

 

mod list:

3mm engine built by RX-7 World, BNR stage IIs with custom Garfinkle manifold, M2 med IC, 3" Pettit exhaust with SR resonated mp, manual boost control (14 psi), ACT s/s, Roja 5 spoke 18s, Brembos/Hawk pads/braided lines, Bilsteins/Eibachs, all emission crap deleted, PWR rad, 850/1200 injectors, PFC tuned by BDC, braided fuel lines, Aeromotive FPR and fuel filter (mounted above differential), Supra pump

 

The Lightning can't fight from a roll or high speeds, it's weight and aero dynamics obviously are the problem. It's designed to go from a dig, that's where they shine. Expecting him to continue at 120mph is just dumb.

 

again, you don't understand basic physics and rolling resistance, if anywhere, the truck has maximum advantage at about a 50 mph roll, which is what we did...from a dig, the maximum advantage of power to weight is realized

granted, the poor aerodynamics of the truck kill it at triple digits, but supposedly he has 390 hp

Road load horsepower is the power required for a vehicle to maintain a constant speed on a level road. It is the sum of the powers required to overcome the car's rolling resistance, and aerodynamic drag.

Rolling Resistance
Rolling resistance includes power train losses, wheel bearing losses, and power losses in the tires. Of the three, tire rolling resistance is the greatest, and so dominant that the other losses may be disregarded for first-order approximations.

The force of tire rolling resistance in radial-ply tires for passenger cars tend to be about 1.2% of the car's weight at 30 mph (48 km/h), increasing to about 1.6% at 70 mph (113 km/h), when properly inflated. For a 3000 pound car these equate to roughly 35 and 50 pounds of force at 30 and 70 mph, respectively. Under inflation or excessive weight increase tire rolling resistance considerably.

Aerodynamic Drag
The force of aerodynamic drag is a function of a car's shape (Coefficient of Drag), size (frontal area), the square of it's speed, and (to a minor extent) its altitude. For a mid-size sedan this equates to about 20 and 90 pounds of force at 30 and 70 mph, respectively.

Modern cars have drag coefficients (Cd) ranging from 0.30 to 0.50 (with pickups and SUV's being somewhat higher). To give some idea of what these number mean, here are typical Cd's for some other objects: an airfoil, 0.05; a ball, 0.10; a narrow (30°) cone, 0.34; a wide (60°) cone, 0.51; a square flat plate, 1.17; a parachute, 1.35.

Road Load Horsepower
Horsepower is a measurement of a force applied at a speed. Both rolling resistance and aerodynamic drag are calculated in terms of force. At any chosen speed, these forces can be resolved into horsepower requirements. If the car can supply that amount of power to the wheels, then it can maintain that speed. Total road load horsepower for a typical mid-size sedan is about 15 hp (11 kW) at 50 mph (80km/h).

Since rolling resistance force is not a function of speed, then rolling resistance horsepower (a function of speed) increases proportionally with speed. Since aerodynamic drag force is proportional to the square of the car's speed, then aerodynamic drag horsepower increases proportionally to the cube of the car's road speed.

It is generally accepted that, on a typical car, its rolling resistance and aerodynamic drag become equal at about 50 mph. So at twice that speed the aerodynamic drag is about 4 times the rolling resistance.

 

I wasn't asking for a physics lesson...

 

Lightnings fall on their face at speed.....

Going from a slow roll or a dig (if he has traction) ......you would have been suprised....

and NO a lightnings strength is not from a faster roll....get real

I raced a mild modded 03 multiple times from a dig 2 years ago, I was back in the hybrid stage making right at 300 wheel..... it took me till about 80 mph to put 1 car on him, but after that it fell on its face very rapidly

and on upgraded twins at 14psi there is no way your much above 300 wheel... which is where my car was running at during that time


looked over at 120mph + and laughed huh??...... smart and cute

"put it in 5th and cruise to about 140"... also cute

noob

 

lol..

 

Damn, Mark. No matter what username or what subforum, people are always hating on you.

nice kill. Lightnings are nice trucks, a hell of a lot nicer than SRT-10s.

Maybe this summer the FD will be running and I can come down to do some highway pulls with you.

 

Were you really just looking over at 120mph? That's pretty dangerous :P

 

Why list all of the stuff that has nothing to do with HP??? Do we really need to know what fuel filter you have???

 

you can't argue with the Laws of Physics, ********....or, you can try, but I for one will laugh at you

assuming both parites can hook up, the maximum advantage of power to weight (which the FD has in spades) is realized from a dead stop...study the concept of rolling resistance and take a basic physics class before your next stupid post, ok?

I have more than 300...it isn't just BNR Stage 2s, it's a ported engine, ported y-pipe and manifold, and wide open 3" exhaust...heck, people have made 350 on a Pettit ECU with stock turbos running non-sequential

smart and humbling to the hicks in their pig truck with the custom plate

the funny part was when he tried to catch up for another run and I gave him a big thumbs down

thank you....happens just about every weekend

 

it's a world of many fools

 

ever heard of Drag Coefficient...?

obviously not.... or i guess the fd has worse drag coefficient than a lightning...

what a ***.......

must get off copy/pasting stuff in posts, make you feel more or less like a douche?

 

the lighting has relatively quicker lower speed acceleration, coefficient of drag takes over at higher speeds, simple as that.

same reason why Evo/STi's fall on their faces after 100mph, relative to their acceleration under 80mph.

with a crappy Cd u need sheer power to overcome it, which in turn keeps the low end acceleration faster than high speed acceleration.

i've personally witnessed a lightning off a rolling start. from 40-100mph he was flying, after 100 it seems like he hit a wall or somethin

 

id beg to differ.... he is probably around 350whp if tuned correctly. 14 psi on stock turbos and ports with an aem ems gave my friend 324whp on a mustang dyno..

 

yep

 

Yeah Mark....you're getting no love here buddy! Had this been someone else's post, there would have been 'ooohs' and 'aahhhs!' about what an awesome kill it was.

The Lightnings I have seen getting serious have always been pretty damned impressive.
I was cruising back from KC once about 85 or so, and suddenly these two Lightnings came out of NOWHERE and ******' FLEW by! I would say they had to be at 130 mph or more...the shockwave in the air from their passing literally rocked my car from side to side pretty violently.

And then a guy I work with who owned a Lightning raced another co-worker's '67 Camaro running a 350 hp 327 with a 100 shot of nitrous and just destroyed him. It wasn't even a race, I kid you not.

I guess I am just saying that in my opinion, Lightnings are not to be taken lightly, and....good kill.

 

thanks baja

 

Good kill, I just dont get why you are impressed with the fact that your car beat a truck at high speeds.... What did you expect, him to be able to go up to 140 with you. It is after all a truck. Good kill, just kind of expected once you reach high speeds.

 

not sure if you read the story, but he had the jump getting on the highway and I pulled even with him at the top of third, so basically I pulled on him in his "sweet spot" less than 100 mph...it wasn't just a 100+ race

 

nice ricer flybye at 120!

 

or, more accurately, F-150 destruction from 50 to 120

 

No, I do understand you pulled on him between the speeds where he should shine, and I congratulate you on that. It is no small task. My family has a 2003 harley davidson edition which is almost the same truck just heavier with a different pully, and its pulls well from those speeds. I am just saying that going by at 140 doesnt really mean anything. Sorry if you take it the wrong way, just saying that at a point its pointless to even race. Good kill though, they can be beasts.

 

That's exactly how they are. OP is a retard trying to race one at 120, may as well been a Hummer or school bus

Seeing how I owned a very modified FD for nearly 6 years, and now a Lightning, I think I can speak for the aerodynamics and acceleration differences of each at 120+ mph better than you..
