I need some advice on what would be the best mod to increase my low-end torque. I talked to some guy with a Mustang GT and he was telling me even with a Vortech Supercharger, which I was thinking about getting, still wouldn't matter. He could still take it with his stock engine. So anyway, I don't know much about engines, but I'm trying to learn so I would like to know what is the best thing to do?

 

Want torque?
Downshift!

 

What i meant was i wanted to know what i could do to get more low-end torque off the line. I'm sure you know what i meant, but thanks for your comment. It really helped!

 

The superchargers currently on the market will not improve low-end torque but a turbo will. The Speedcraft set up produces over 200 lb/ft. of torque at the wheels from around 4-4500 RPM's on up.

 

Speedcraft helps more from mid to high-end. Not a whole lot you can do right now for low-end.

 

Does your Mustang guy have really, really dark brown eyes? You know, from being so full of shit! (Or they're so full of their cars that they don't get out much) Go to any magazine and take a look at the performance summation near the back. Take a look at the numbers for a Mustang GT and an S2000. Oh hell, never mind, I'll save ya some page flipping:

Car and Driver, Nov./02, p.174.
0-60/14 mile:
Mustang GT (tested 09/02): 6.3 sec/15.1 sec.
Honda S2000 (tested 10/99): 5.8 sec/14.4 sec.

I'm sure you'll find some faster times for the Mustang but then, there's faster times for the S2000 too. Just compare the numbers in the same mag. There have been times as low as 13.8 sec reported in one mag (Motor Trend, I think). 13.7 sec timeslips have been posted on this board by a member.

You want low end grunt:

ps. I was a "Mustang" guy a long time ago and the Mustang was ALL THAT to me, too! (Don't tell anyone, but I'd buy an SVT Cobra today if I were in the market for a new car - "maybe". But for now, the gears and the upcoming Vortech S/C kit will keep me amuzed.)

 

Engine torque is only part of the story. You must calculate torque at the rear wheels to have a valid comparison. Even then, the Mustang is likely ahead of the S2000 initially. But because it has a rapid torque drop-off, will not out-accelerate a well-driven S2000.

 

...or more precisely, it's only part of the equation. The equation being:

HP = (torque x RPM)/ 5250

My emphasis is on the part that says "torque x RPM\"

Torque by itself doesn't do anything. It's all about power and as the equation shows there are 2 ways to increase it. So why is torque considered more valuable than RPM? I don't see a lot of posts on the SVT board that state "My car needs more RPM's" Yet that is the exact same argument as "the S2k needs more torque." You want more torque, you need more displacement or FI. I agree with xviper - go buy a Cobra. Not bashing Cobras - I would love one too! (Not instead of an S but in addition to )

There was a thread that linked to agreat article on this subject. I copied it into word and have read it many times. I will try to find the link and post it here.

One of the best articles I've read explain torque vs. horsepower.

Bottom line:
"It is better to make torque at high rpm than at low rpm, because you can take advantage of *gearing*."
