Yeah, the only way to significantly increase low end power is with Cubic Inches, or forced induction. Though lower gearing can get you "into the powerband" quicker, at the expense of increased cruising RPM.

He's talking about the Civic Type R. Take a Boxster to 8600 and BadThings™ will happen.

"What is an underdrive pulley? Any brand names? Common part or special order?"
You didn't ask for "a preferred version" or "parts based on experience." :confused:

The search function works great here. :)

No, I did not. Sorry I did not follow proper Internet protocol. I have to admit, I could not for the life of me figure out what that was and indeed, just started typing without doing a proper search first. Sometimes thesr questions get unsolicited replies about favorite brands or types. To be honest, it never even occurred to me to do a search for "underdrive pulley". I'll do the search from now on before I just type a question that comes to mind. Thanks for the links and info. Ordering one today.

Here is another bolt-on mod with time tested technology that should add LOADS of low-end torque. :)

Red Green ~ More Power with a porcelain carburator

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. ;)

According to the above link: chetah****

"Horsepower increases should be up to 15hp at the crank, and this estimate has been verified from dyno results with other similar pulleys. This pulley is intended to work with any Porsche that has a stock pulley number of 996.102.115.63. "


That's a tall order... Not sure I'm buying that?

bc

Yes and according to Porsche, no "discernable" difference in performance...;) 2002 S shows tested 0-60s ranging from 5.3 to 5.7secs. 2004 550 5.2 to 5.7secs. My 02 makes 85% of max torque by 2000rpm. Low end torque is not the issue with the 3.2s, however some additional top end poke would make the cars feel more Porsche like in my opinion.

I spoke to Jake Raby a few years ago regarding Flat6's underdrive pulley. He says that the pulley was good for 10hp above the standard item and after fitting mine I would tend to agree.
The improvement is felt in the lower to mid range revs, just were we drive most. Its not a difficult or expensive replacement and after 3 years of operation I still believe its the best cost effective mod I've invested in.....

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 .

Interesting. I may give it a try

Pup

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

The underdrive pulley doesn't give more power at the crank - not possible. It just means less of the original crank power is wasted on ancillaries like power steering etc therefore more at the wheels.
