You got it man You take the torque the engine is making at your observed HP level. This also helps calculate how much power your car really makes. Car companys won't underate torque (in most cases) but will HP. So throw out their rating and calculate the new one. That is why people get so excited about LT1's and LS1's. It is amazing how underrated those motors really are and the power curves they produce.


In defense of stu (I will dodge bullits for this) he claims he has no torque and only hp until he hits boost. Really, he does have a lot. It just arrives right when his HP does

EDIT: This why you will never see peak torque after peak HP.

actually that equation is right
at 3200 rpms the motor is only putting out 201hp
horsepower generally goes higher as rpms rise.
also if you look at the equation and flip it around you can figure torque

tq=(hp*5252)/rpms

so at 4400rpms when the motor is putting out 230hp you have 274lbs/ft of torque


again horsepower is nothing more then a number derived from math. it has it's uses but when taken to a dyno the dyno only calculated torque and then uses mat to figure out horsepower based on that

if you are curious go to howstuffworks.com and look up horsepower



as far as the lt1 and why it makes more horsepower and just a tad less torque is because the lt1 has a much broader torque curve and makes torque higher up in the rpm range ulike the l98 which falls flat on it's face at high rpms thereby giving a higher


like if you have a car that has a perfect flat torque curve from 1000rpms-10000rpms (theory I know cause it can't happen) the torque will stay the same but horsepower will rise in proportion to rpms for no other reason then that is how the math works

Thank the LORD. I think you are the first to say that.

There seems to be a lot of confusion about this equation, everyone seems to know that math is involved, but not why. Let me see if I can break it down for those who don't quite grasp the idea here.

Torque = work.
Horsepower = how fast you can do the work.

It's the difference between being able to lift a weight at all, and being able to lift that same weight in a certain amount of time. In fact, the actual quantity of what one horsepower is, is moving 550 lbs, 1 foot, in 1 second.

So, you can move 550 lbs 1 foot and have it take all day long. As long as you move the same amount of weight the same distance, you will have achieved the same amount of work; which is torque. But you'd have to move that weight 1 foot in 1 second to have achieved 1 horsepower.

stu

Torque = work
Horsepower = work x time.

No, they are ugly compared to a thirdgen...they are as attractive as a honda civic..not to mention the interior room in them. i'd take my beaughtifully designed ,bigger thirdgen over a mustang, even though it is heavier- any and every day of the week!:hail:

25thmustang

I'll take my poorly designed, small interiored, smaller car over your LO3 (which I might add is slower than my well designed much larger Jeep)... See opinions are just that and are not valid when fighting facts!

nick418

i thought you loved everything about your car?

TBI92Camaro

Opinions are like @$$holes, everyones got one.

Even one for imports too but im not sharin it, though im sure youve all heard it Plus, I wouldnt wanna offend our good pal Stu, though he is light hearted about the Import hate on this board lol.

25thmustang

I was being sarcastic... I do love everything about my car, including the fact it has now been in a national Mustang mag!!! Theres a link in my sig too, the last line, click that!

Did i say it was fast???no, i didn't think so.As stated i was responding to the post saying 5.0s are ugly which they are,and nowhere di i mention my thirdgen having the edge performance wise.

25thmustang

Good, then you know that opinions mean nothing, its the solid facts we can use as comparisons...

mustangs are fairly attractive

but can you fit a 11 inch wide rim on the back with 315 series tires?

thirdgens can and with that and nice cowl hood, the look is evil!! LOL

25thmustang

No need, my car hooks on 245s (as shown by the 12.9 timeslips on street radials, with bolt ons )

With the right offset and no quad shocks I have seen 315s on Mustangs, on 10.5 rims. I had 275s on mine which looked good, but looks are subjective, power isnt!

rx7speed

yeah but can you guys 1g on the skidpad and a high 67 low 68 on the skidpad using stock street rubber



and only use 225 width tires?

25thmustang

Hmm, I have tried that with the skinnies and no sway bar. Lets say, it isnt pretty! (No I have NEVER tried this). I am the first to say Mustangs are a joke when it comes to handeling until you do a lot of suspension mods!

rx7speed

you guys started going off on "yeah but cna you do this" thing so I figured I would join in

wawawawawawa i still getting this thread in my user cp because i posted once here.
