ohhh, ok, i see now. it refers to the torque at the HP peak. i though it meant torque peak and its rpm divide by 5252 and you get peak HP
what you get is hP at that Torques peak rpm of 3200. 201hp at 3200rpms

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.

and the Lt1 responds greatly to cam swap cuz the intake is designed to make power up to 6000rpms or higher. stock cam is barely any bigger than L98 cams which peak around 4500rpms-5000rpms. so put in a hot cam or bigger in a LT1 or Lt4 and you got mad power increase.

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

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.

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.

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.

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

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!

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?
