Gearing/Weight

So what is the difference between a turbo inline four making 300 lb ft between 3,500 rpm and 7,000 rpm and a v8 making 300 lb ft between 2,500 rpm and 5,000 rpm? Not very much with the difference in gearing to suite each engines working speeds..

So the comment "my engine makes more torque at 2,500 than yours does" is pretty much completely useless when the two engines you are comparing have COMPLETELY different powerbands and gearing to match..

Weight, most v8 cars weigh more, probably why they have v8's, and vice versa, common sense. So car X has 150 lb ft more torque but weighs 1000 lbs more.. Sure it looks great on a dyno and posted on the net, but you really have little to no advantage on the street because of a heavy ass car in the first place..

Not directing towards anyone, but I thought I would throw the obvious out there!
Low end torque is exceptional at moving big weight and is why diesel engines are prefered to move heavy loads. The more torque you have the less the engine will slow when you drop the clutch and when you weigh close to 4000lbs big torque helps. Gearing changes help some by moving the wheel torque by icreasing rev speed at the sacrifice of wheel turn but it does not completely make up for the torque difference. And remember, when you lower your rearend gear, you can also increase the number of times you have to shift. And once more I can go back and ask "where does the car make its peak power?" Supra’s are always a great example. A mid to high 10 sec. Supra will usually trap about 10mph higher (140+) than a bigger displacement car such as a mustang or camaro (130+). Go look at some timeslips, I'm not making this up. Judging by the mph the Supra obviously made more peak power but the bigger v8 car had a more usable powerband. Thus the Supra guy brags that his car made 700hp and the Mustang guy brags that his 500hp car stayed beside a 700hp car. And also I believe turbo supras weigh around 3600lbs – not very light for a non-v8 car.

Gearing can and does make the difference. You have to have a much "lower" gear to make a high rpm car even have the same shifting points as a lower rpm car.. just think of it all relative to mph, not rpm.. thats why I sometimes love to see MPH axis dyno's

Sorry, but mid 10 second supra's trap higher with similar times compared to other cars not because of the torque curve, but because not many Supra owners want to butcher their street sports cars to make them dragstrip specific, like many muscle car owners do. So they still go the the strip, but with 6 spds, and DOT slicks or street tires.. compared to high stall auto muscle cars with suspension work for launching. Kinda hard to compare the two...

Compare Supra's that have been drag prepared and its completely different.

On a turbo car, also, the whole "torque off the line" ordeal can pretty much be thrown out the window because of anti-lag or full throttle launch/2-step/etc etc.. Boost off the line helps

Full throttle launch doesn't work well on drag radials and slicks are a bit hard on the car when trying to keep it unbutchered. And your right there aren't any unbutchered mustangs running 10s with things like IRS, 6spd, full weight, ect. And 9s with those things would be unheard of. And I am well aware of the relationship between gearing, rpm, and mph. You didn't seem to understand the simple relationship between weight and torque. I'm done.

Tell those things to Ryan Woon. Is the fastest manually shifted 6-speed car a Mustang? A Camaro? A Corvette? A Viper? Nope. Its a Supra. That even amazes me. IRS with the Toyota 6-speed and everything that was on the car from the factory. Supras trap so high because they are hard to drag race, and most of these times you see are from 6-speeds. Supras are now pulling the front tires off the ground.

Torque does mean a lot, its gets the car moving. But saying you have torque down low doesn't mean anything as long as the other car knows how to use his torque even if its at 5000 RPM. From a roll brake boosting it key, and from a stop 2-step/Anti-lag is the shit.

Torque= How hard you bang your head against a wall argueing on the net.
Horsepower= How fast you bang your head against a wall argueing on the net.

Well I can imagine.. I know its difficult on street tires lol..

I completely understand the relationship of weight and torque. A car with more torque is less effected by extra weight, I understand this.

Hahaha, I like this..

The key is, banging your head as hard and as fast as possible, throughout the entire argument, correct?

Depends on the weight of your head but generally speaking youre correct .

Not too often I hear something new on the boards, but this is funny.
