The ASP pulley was shown to increase Buellwinkle's hp by 29 and torque by 35. With the stock air filter he lost 5.9hp and 2.0 ft-lb torque. Note, this was with base settings, therefore lean.
I have not seen the dyno results from Stage II and base ignition, but I am extremely happy with my performance gains for the $369 spent (includes pulley, $7 s/h and $12 belt).

THANKS A MILLION
This is all I need to take the plunge.
I am waiting to complete my self imposed 6 month breakin period. Just to make sure I would not have any nasty surprises.
Then the pulley it is.
220 HP & 230 Ft-LB WOW
for less than 400 bucks. WOWWWWW
THANKS ALL

BlackC230Coupe, all you need other than tools to install if you are doing it yourself.
Benzer, allow yourself a month lead time to order the pulley so you won't be dissapointed when you are ready.

Sorry, but I forgot to add the cost of new rear tires to the pulley upgrade total. ha ha

Im probably going to take it to a shop so I dont have to worry about Belt Sizes & Tools. Does anyone have a website or phone # for ASP? Also does the pulley void any warranties?

Call Lee at ASPRacing.com at 1-877-928-8678. Don't try to order from their website, it's not there.
Don't know how an aftermarket pulley affects warranties in foreign countries. In the U.S. there are laws to protect consumers against manufacturers' denying warrantties because of aftermarket parts.

I just installed the ASP pulley and want to share some notes on Buellwinkle's installation guide:
On Step 8: Remove intake hose on right side of air filter box by pressing on clip that sticks out and [turn it to the left; then] pull hose away from air filter box and pull straight up.
I also needed to pry off the factory pulley, but I was able to slide the ASP pulley a little bit onto the crack shaft, then use the bolt to guide it in place. Total installation time was about 1.5 hours and I was going super slow.
From the test drive experience: very noticeable power increase from gears 1 through 4 at base ECU and ignition settings. But also because of that I was hestitated to floor the gas so I did not notice any significant gain at higher gears. Anyway, all I wanted was more lower band power, and I barely floor the gas, so I am happy with this
Thank all of you who provided helpful inputs and opinions related to the pulley. I love this forum!

i think you're pretty much screwed if something goes wrong. that act is nice on paper, but unless you're willing to take legal action (and how many of us are?), in reality, you don't have much choice.
luckily, there is a german car specialist nearby... i wonder how much they'd charge for swaybar installation? 1 hour labor?

Hello VaDIM - Been Nearly 3 months since the install
Hello vaDim - I think this is a good time to ask
Can you give up one more update on the pulley peroformance and any side effects (good or bad)??? I will be off the 6 months "test drive" period in January and the addition of a pulley is on my schedule.
Thanks
Benzer

The engine is noticeably louder, especially at idle and at WOT, otherwise the same or close. I like it better this way, as the increased S/C whine/growl masks the notorious clickety-clack sound that many detest so much (myself included). As a matter of fact, I wouldn't mind having a deeper bass note in the exhaust sound.
So - I'd say go for it! The day you put it in your face will look like this ->

When installing any pulley or gear such as this, and the new pulley is too tight on the shaft to install without force, a time-honored trick is to heat the pulley gradually, up to a reasonable operating temperature as it would see in regular use.
For something as small as the pulley, a toaster oven will do.
The pulley should slip right on the shaft after that, particularly if the shaft is cold (and therefore at its smallest).
Don't forget to use a glove or potholder, or the pulley install will be the last thing on your mind as you undergo skin grafts.

Now, the car feels a little rougher (my settings are "Base" ignition and "Stage 2" fuel), and I seem to feel this even through the shifter knob. No fault codes have been thrown, though. Not sure what this means, maybe I should try different fuel/ignition settings and compare? Or maybe it's the tires - they tend to roughen the ride as they wear off.

A few thousand miles with the pulley - no side effects (that can be easily noticed, that is). Same strong performance as on day 1; no oil leaks; no additional vibrations; no rough idle; no torque peaks or dips.

It's the latter... The first quote reflected my being worried - I guess I was too concerned about the results at the time. Or maybe the ECU was still adjusting to the pulley.

I can definately become "oversensitized" when concerned, so I understand that Part throttle operation the ECU will most certainly have a "learning curve" for the extra airflow, but WOT fuel/spark values are usually mapped into lookup tables (this is what the "stage 2" or "base" settings alter) with an active knock sensor being able to pull spark out. Systems I am familiar with have multiple spark tables for the knock sensor to use (i.e. -short term and long term knock) so it pulls a small amount of spark initially and if it still sees knock it goes to the next table and pulls a lot of spark out.
MB products are calibrated for 91 r+m octane (95ron) so if you can get 93 r+m (97-98 ron) you have some cushion (which probably evaporates with the extra boost and may end up being close to "just right")
The engine will have more roughness at WOT for sure (you eliminated the torsional damper) but that does not mean you will feel it in the car. These vehicles have a lot of effort put into NVH so that vibrations won't make to us.
Good Luck and enjoy the extra power. These cars should have more power for the cost in my view. I think MB would sell many more if they ever figure this out
But don't anyone hold their breath...it gets worse in a few years from what I'm hearing.sorry for the rambling, hope some of it helps.
