Is there anything I can do to a 2004 TSX 6sp manual to increase the low-end torque?

 

Not a whole lot at this point. Most of the mods that are currently available bring increases at 4000+ rpm.

Supercharger is the way to go to get low down grunt, but they won't be available until some sort of fuel management package is on the market.

 

So until then, we have to face the fact that we have a sporty Acura
that most honda's can easily beat in the race at get go? damn

 

exactly! our car looks fast, just cruise, dont race, then nobody knows how fast you are

 

If you were looking for a drag car you bought the wrong vehicle. The TSX's strength is in its handling, not straight line speed.

 

Not if you race most stock Hondas because they probably have even lower torque with their smaller motor.

Btw, the stock TSX has more torque than my supercharged Civic with the 1.6L motor.

 

you have a supercharged civic?

 

I still have the car but sold the SC and used the money as part of the TSX payment. Can you tell I haven't changed?

 

 

 

You can put ANY amount of torque you want to the ground by changing the gear ratios. The drawback is that you will lose top speed and have worse fuel economy on the highway. I don't think aftermarket gears are available for the TSX, but someone could probably do a custom swap for you.

One simple way to effectively shorten the gears is to run smaller diameter tires, ie. 215/35/17. It will look ghey and your ABS/speedometer will be screwed up, but you'll put over 10% more torque to the road in every gear at every RPM.

 

Changing gearing doesn't make more torque it will only shifts the curves. This will put torque to the ground sooner but not put "ANY" amount to the ground. It will only apply whatever the maximum amount of torque the engine can make. Check out this spreadsheet I have hosted at my site.

(I could add a 6th gear if needed)

The only thing that will make more torque is actual changes to the engine.

 

A 10:1 reduction has 10x more torque than a 1:1.

 

So if I make 100 ft-lbs of tq your saying by changing gears I can make 1000 ft-lbs without modifying the engine?

Engines make troque, transmissions (Gearing) affect how/when it is applied to the ground.

 

If the input gear is spinning 10x faster than the output gear, the output is 10x more torque than what is going in. The horsepower is the same but the torque is changed.

I'm with you now Dan. I was thinking about it wrong. My point of reference was at the engine where no more torque is actually made but I should have been looking at the wheels.

A freind just asked if this wasn't a moot point due to the lack of gearing options. Doesn't the RSX have a more aggressive 1-6 than the TSX and then allow you to use a TSX FD?

 

I'm sure you could find the ratios on Google. I don't know if the gears are compatible however.

 

How much torque will be too much for FWD to deal with??

 

You might not be able yet to do much to increase the engine's torque output, but you can do some things to help it feel it has more torque. Weight reduction for example, especially reduction in the weight of rotating masses between the engine and the road.

Damnit... does anyone know how to submit TABLE tags in this board? Otherwise the table looks really garbled.

 

I appreciate all the input and healthy debate

It looks like for now, I will have to say "sorry, I don't race" LOL

 

Oh, I don't know, you can still out corner them. This morning a Mazda5 was annoying me, tailgating me as we headed into a sweeping overpass (Austin: NB Mo Pac onto NB 183). I just held my speed as we headed into the turn rather than slowing down. It turns out his balls shrank to the size of peas , and he couldn't keep up.

 

Mazda5 as in the mini-minivan?

Anyway, good story! I myself love to out corner annoying drivers like that. Especially when that can usually be done not too much over the speed limit

 

You're right, the 5 is the new minivan.

I guess it was a Protege' 5 or whatever they're calling it. The hatchback. Come to think of it it might have been a 3-door...

Whatever it was, it was light on testicles. I actually enjoy out-corning just about any kind of vehicle that will let me. I'm not ashamed to say I felt good one time watching an Expedition freak out mid-corner because it couldn't keep up.

I really like doing this stuff in my wife's V70 because it's so soccer-mom. Nobody expects it to go flying around corners . It's a little drifty compared to the TSX, but that's fun too.

 

LOL.... Who in the right mind would try to "corner" in an Expedition?!? That guy needs his wires checked!

I hear you on the V70 man! The under-dog look adds to the fun
