First step to increase low-end torque?

Interesting. I have an 02 S, and I think it has one of the flattest power bands of any car I've driven. If anything, I would like more poke in the upper rev range. Yours becomes a rocket above 3k huh. Mine is flat from ~1800 all the way up with a very slight "step" at around 4500rpm. It's plenty fast, it just doesn't feel fast until you look at the speedo...

60-120 is WAY faster than 0-60. I would say it has twice the pickup over 3k than below. 1st does 45 or so, 2nd is like 75, and 3rd is well over 100. 2nd & 3rd are much faster than 1st.

Exhaust, exhaust, exhaust !!

Timco, while gear ratios are relevant to acceleration, it has nothing to do with HP/torque, only how at hp/torque is applied to the road. I don't see how you top speed in every gear is even relevant.

I understand this, but was saying that 2nd, 3rd, and so on feel much faster. Yes, top speed is irrelevant. Wrong way to say it. I'm talking 3k and under, or off the line power. Small add ons or upgrades are great, but I'm not swapping my exhaust quite yet!

Low end torque?? 4.0L motor.

I suspect most inexpensive bolt-on mods will leave you highly unsatisfied. Good luck in your search.

I was under the impression that it was not good for these motors to drive them at low RPMs. Keep it above 3000 is what I have read.

Agreed, but getting there is what I was wondering about.

Well, if it ain't there........

It ain't there......

you should at very least delete your secondary cats . that and a BMC air filter gave me a good boost in power and much more so in the upper revs. I did not notice much gain with the pulley. believe it or not but replacing my rear wheel bearings gave me a good boost .

Now, keep in mind I have NOT done a proper search, but is there a straight pipe that replaces the secondary cats? I was unaware that there were two sets. Easy job? I'll do the pulley soon enough, and de-snork or go big air filter, but this cat thing sounds doable!

My new bearings made my car feel slippery as it glides along the road. Just because they don't grind and howl doesn't mean they're not loud or stiff.

there are several brands of delete pipes out there. It is a fairly straight forward job. if bolts and clamps are not to rusted it is very easy.

There is no substitute for cubes if you are after torque. Everything else is miniscule and the costs can lead you to the poorhouse.

Some options

If I was a gambler, I'd bet big money here and now that this is wrong.

Let's say that your Boxster does 0-60 in 5.8, or 6 seconds or even 7 seconds.

According to a gps verifiable system, a stock Panamera TT does 10.14 in a 60 to 130 run.
Same car with an ecu tune does 60-130 in 8.28 seconds.

Even if you take into consideration the extra 10mph and the time required, do you think any Boxster will beat their 0-60 time going 60-120?

Oh, get the underdrive pulley for the best gain and it saves your power steering pump too.

Interesting. I'll time this tomorrow. I'm just going by feel.

What is an underdrive pulley? Any brand names? Common part or special order?

Thanks. Yes, google is my friend, but cannot offer a preferred version of the same part, assuming there are a few brands out there and dozens on this board have likely used this part and have a opinion based on experience. Google can't do that....yet.

That's why I asked.

If your not happy with the Boxster you should try my Civic Type R, nothing much happens until you get to 5400rpm. Red line is 8600rpm so if you keep it in this power band it is swift.

If you want more grunt lower down in the Boxster, supercharging is the way to go.

All spoken like a TRUE RACER! DFW02S SHOULD KNOW - he has been to every track around here testing!

BTW - Cold Air Intake was the cheapest bang for me! Less than $100 - built my own - there's a thread on it somewhere here (you can pay $200-$500 for one - so be aware).

UD Pulley (a good one like RSS) is $200. Be careful filing down the boss. And make sure to include a new crankshaft bolt, another $10.

For $250 you could have a nice-sounding exhaust with reasonable grunt in the low end. Combine that with a Cat Back system (around $150) and you are off!

Individual results may vary!

You forget he's rocking 264hp to your measley 250.
