Can someone help me figure out these two out? I'm just looking for desktop figures.

What follows is a standard relationship between power , weight, trap speed and 1/4 elaspsed time. Covers weights from 1250 to 5000 pounds, and from 75 hp SAE net to 750 hp SAE net.
Just some notes to you. Torque is really irrelenvent to this excersie. It is true, however, that Power is a torque (twisting force) per cyle of the engine, ie there is a speed factor involved. It doesn't matter if you use a Mazda rotary with next to no torque bellow 4000 rpm, or a 460 Ford with vitrually power and torque everywhere. If both have got 200 hp, it doesn't matter if the Madza has 185 lb-ft and the 460 has 430 lb-ft, and they are both in 2500 pound cars...they will both do 13.5 second quarter mile times potentially. But the Mazda will lag over the first 60 ft and 660 ft areas, and then catch up on the end part.
The chart below is based on a stock 1966 Falcon-size intermediate, with no slicks, full exhast, conservative barometric temperature and bad areodynamics. The following
-Hp verses over all drag factor times the frontal area,
-Low end torque
-Slicks, drive configuration, transmission type and weight tranfer
all change the results slightly, but no more than a couple of seconds at worst.
Formula for Elasped Time
Formula for net Horse power at the flywheel
Formula for Calculating Weight
Trap speed in mph
*Note: These are more conservative than the Moroso "dreamwheel" HP calculator because it is designed to baseline an optimised drag car with no major exhast and slicks and what not, not a real street car with softer springs and more of a compromised set up.

Just some notes to you. Torque is really irrelenvent to this excersie. It is true, however, that Power is a torque (twisting force) per cyle of the engine, ie there is a speed factor involved. It doesn't matter if you use a Mazda rotary with next to no torque bellow 4000 rpm, or a 460 Ford with vitrually power and torque everywhere. If both have got 200 hp, it doesn't matter if the Madza has 185 lb-ft and the 460 has 430 lb-ft, and they are both in 2500 pound cars...they will both do 13.5 second quarter mile times potentially. But the Mazda will lag over the first 60 ft and 660 ft areas, and then catch up on the end part.
The chart below is based on a stock 1966 Falcon-size intermediate, with no slicks, full exhast, conservative barometric temperature and bad areodynamics. The following
-Hp verses over all drag factor times the frontal area,
-Low end torque
-Slicks, drive configuration, transmission type and weight tranfer
all change the results slightly, but no more than a couple of seconds at worst.
Formula for Elasped Time
Formula for net Horse power at the flywheel
Formula for Calculating Weight
Trap speed in mph
*Note: These are more conservative than the Moroso "dreamwheel" HP calculator because it is designed to baseline an optimised drag car with no major exhast and slicks and what not, not a real street car with softer springs and more of a compromised set up.

Gee, I guess this means our 1966 Mustangs with an I-6 200, cutting the lights at ~70 mph in an 18 second quarter mile, were putting down a whopping 80 hp.
I WANT MY MONEY BACK!!!

From the table, an 18 second quarter mile would be needing in excess of 100 net flywheel ponies for a car that must weigh in at about 3000 pounds (horse and rider, remember?) 18 secs is about 75 mph trap speed. Don't knock your stead, Stan ma main man! (trying to do my best Yosimite Sam voice )

Haven't quite worked out the relevance of 60' times, the trap speed, and if it ties into vehicle weight.
Are they at all related?

60' times will usually give you a good idea of off-the-line traction. ET shows how your chassis (and traction) are doing. MPH shows how much HP you're making (if your gearing is setup correctly). Vehicle weight effects everything.

We need a Virtual Spectator Quarter Mile site on this website. You log in your default power/torque curve for your vehicle, and have Bench Racing sesssions like GT2.
Federation Against Rotaries and Turbosstrikes again!
:chill: The quarter mile calculations only need the net flywheel HP and the weight to do calcs. It assumes an optimised chassis, as Whittey says. (If you use the Moroso calculator, there is an extra half a second in it.)
Eg. 1 100 hp Stang, 3000 pounds with discokin6 and his 8" inch knife at the wheel verses Mr Bean in his 50 hp 1500 pound snot green Mini...both 30 pounds per hp cars.
The torque band (how torque is delivered) is of no relevance to a 1320 ft, 402 m, 1/4 mile standing start. Things all even out. The overall drag factor (cd times frontal area all over the total weight: power ) raises or lowers the quarter mile times and speed a little. Using a Mini with 30 lb's per hp, the quarter mile value would be 18.7@73mph, with 0.7 loss due to traction issues of a FWD car, and about 0.1 sec gain to the small frontal area which is like adding HP to the engine. The Stang would be about the 18.1@ 75. The Stang would hook up better because of the higher first gear ratio which transfers torque better, and it has a lack of weight transfer which takes weight off the driven wheels. This is what plagues the Mini and other front drive cars.
At the 60' mark, the Stang would be way ahead. At the 1/8 mile, 660 ft mark, the Mini would be gaining fast.
My friend has a 1973 Firebird with 455, it does 98 mph quarters at a best of 13.6 seconds. It creams all Ricers in his bracket at the start, even 4WD Evo's, VR4'S, Skyline GTS 2.5 R33's, every thing Jap just gets wissed on. But he gets taken to the cleaners at the 660 to 1320 foot mark. The Skylines were wicked at full wick, but didn't have the low end impulse to launch the cars hard. Thats because torque wins on the street. It's a measure of net impulse, which high-winding VTEC's and even Sierra Cosworths just can't touch. Miss a gearchange, and it's all over. His 'stupid' old Poncho just gets shoved in drive, and it cleans up the traffic. .
I6's are even better at the 0 to 60 foot mark than V8's if all else is equal. A Ford six doesn't spend a few split seconds trying to speed dead counterbalance weights on a V8 crank from the start line, the engine is instantly pushing a lot of air through smaller ports with less momnets of inertia holding it back. Then the V8 starts to produce power, and it pulls away. A four is always unable to make the lunge at the start like six with a similar weight to power and torque figure can. It's too busy making power through revs, as torque is always less proportionaly.
Now if only I could find the book which estimates 60 foot and 660 feet times. There are net impulse formulas which I have used before, but its a little bit of math to get into. You can take the overall Ist gear ratio, the tire patch and diameter, weight over the wheel, total weight of the car, the peak torque figure at its rpm, and then work it out on a time per 33 ft velocity/ time basis until you've plotted the whole acceleration curve. I did that with my Turbo Cortina, when I was planning to up the boost. But weight tranfer changes, and you end up making calulation stuff ups at the launch because a good six, even turbo'd , will slingshot itself off line even better than the formula suggest.

Yeah, you're right, XE. I was trying to make a joke about the low 'real world' power of the early 'Stangs, but I guess I didn't get the 'winkies' right...

XECUTE: How does your buddy manage to pwn off the line? Just for giggles I googled on a car you didn't mention (Talon TSI) and this is what I got:
http://ca.dsm.org/cgi/DSM-chart.cgi?cutoff=100
Take for example:
90. Norm Lachance - 1996 Eagle Talon Tsi AWD (60'=1.829)
13.694 @ 99.967 mph
Your bud can match a 1.829 with a 13 second pancho? I'm assuming fat slicks with chassis work and not much motor, am I close?

Pauls 455 is just such a funny thing. Cast pistons, 468 cubes, and a stock HO intake with a 750 cfm 4MV Rochester, water injection, redline is 4800 rpm(!) and diff is 3.31 with 10 bolts 8.2 inch and 265/50 15's.THM 400 with Stage 1 kit. Cam is 6H , as are the heads. Front has no sway bar, headers are dropped, and the axle is stock with the pinion angle changed, some slapper bars, and no fiber glass, battery or body mods. The SD 455 hood scoop is removed on the strip, and a huge velocity stack with two 3 X 10" K&N air cleaners stick up like a mushroom cloud!
I'll e-mail a photo copy of his car at the start line. It's 4080 pounds with him in it, and it launches like a slingshot. 98 mph is his best speed, and we think there is 330 hp net at the flywheel trying to get out. He's the only guy Iknow with a V8 he really uses who isn't broke, and he lives on a modest wage. It never brakes things on it....although the c-clip axle has been close to loosing its axles a couple of times!
He is now working on a fiber glass replica Trans Am 400 to weigh in at 2800 pounds, built on a GM Holden sedan chassis, and a 400 HO V8 with 428 Poncho crank. Has been looking at using three TBI throttle bodies off an EA Falcon. These are 32/36 Weber baseplate, and he has a modified 389 Tri-power manifold to go on. Bl**dy good bloke for a GM man...almost as much fun as Chevytown

man this calculator is damm near spot on!!worked out all my old drag racing times and they all worked out neatr right on the mark.my buick with 2400lb's (with me in it) and 255 rear wheel hp 12.6 yeah(best run was 12.68)spot on!!
It's really a lot of cool fun, eh?. Spliced out of a US drag racing book which I hand copied from a mate who had it. The thing is very good for sorting out flywheel HP. So many people can see that there is a lot more ponies lost to the ground than just the 17-26% from a diff and manual or auto trans...there is also drag loss due to the tires. This formua works it all out based on about 32% drive line and tire loss. The net figure is also based on headers and a stricter atmospheric correction than the Moroso. I'm sure there is plenty more there buickroadster...you haven't peaked yet!
Oh an Whittey, Paul says he hasn't cracked the 1.9 second 60' time. I think he has cracked a sub 2 second one though. Virtually no wheelspin on launch, either. The tailgate weighes about 200 pound for a start, so weight transfer is all on the back wheels despite the 650 pound mule at the front. Having tall, wide tires at the back helps.
That Talon is a machine.

Well, you can tell Paul "Gratz" for getting that beast hooked up with a motor that puts out that kind of low end.
