Hi all, I'm the lucky guy that bought SoCalc230K Kleeman pulley that was for sale. Now that the package is due in today, I'm hugely excited about getting it onto the car. I have an apt for Friday a.m. at House of Performance In Huntington Beach. I'm getting the K&N filter and getting the Kleeman kit installed with a colder Copper Spark plug to prevent detonation. I will have before and after dyno's to see the actual real numbers.

I know that you guys like pics, and what not, so I'm going to figure out how to get some up.

I am only going to do two runs on the Dyno. Should it be bone Stock, or K&N w/o pulley? Obviously the last one is the Pulley with the K&N. Realizing that I am only going to do two runs, is their any other way you think the runs should be done?

Next mod is likely AMG Sway Bars, an exhaust, then possibly something for the ECU.

Currently, I have H&R Cup kit & AMG Brake Kit

I'll let you know what the numbers are.

 

Sounds good. Just do a dyno run with the car engine stock, then another with pulley, filter, etc. The K&N filter won't make much difference in HP, but the pulley will.

Re: ECU software, you should just run stock software since most Powerchip & Speedtuning software don't show HP gains.

 

let us know

 

You should get a good 30HP to the wheels...so figure about 230+ at the crank.

 

congrats on the purchase.

 

Hey all, just an update. I don't know if this is going to happen today. I have been sitting out in front of HOP for half an hour and no one has shown up. I had an apt for 9 a.m.??

I mean last night, I made space in my bed for the pulley to sleep with me. This a.m., I sprang out of bed like Xmas morning, and well, minor let down.

So, I'll let you all know what happens.

In their defence, it is raining CATS and DOGS right now, so the guy could be stuck in traffic.

Can anyone PM me a number for the guy. Josh, Peter? I have the shop #, but not a way to directly get in touch with him.

 

Okay, Coordinated with Josh, and we are due to meet today for the install.

As I suspected its due to weather. I don't know what it is with bad weather and pulley installs, but like Eric, I may not be able to run the car through its paces safely today. The rain comes and goes. Worse, So Cal drivers don't know how to drive in rain.

Now I need to find a way to post pics and vid's. Thanks to whoever has the free wireless in the parking lot of HOB.

let us know dooood!~!

 

Detonation is not a problem, never even seen the ecu pull back timing. I wouldn't waste my time on the plugs and you can actually make it worse. This was a problem with the older C230's and SLK230's, not a problem with the 2002. They finally figured out that motor in one of it's last years. The K&N filter will give you zero gains without the pulley. With the pulley, figure on 3rwhp. Also, make sure they reset the ECU by disconnecting the battery for at least 20 minutes.

 

Wow, m111 engine has so much more gain with the Kleeman Pulley kit than the m271 engine. And the stock numbers they posted for the m271 are incorrect.

 

Okay, yes, I got it done. Yes, I have been acting like an absolute idiot on the 405 tonight. I promise to be better tomorrow. Really I will.


You can feel the differance. The car will pull, cleaner, and rev faster. It is quite a bit fun. HOWEVER, this is not a end all end all. I have alot of work to do on the car. I'm going to give you the increase numbers, and later in the weekend, I will get the video, and pics up. Best part of the install, was my girl dancing in front of the huge cooling fan during a pull .

I gained at the wheel SAE

18.X horse
14.x torque

total numbers at the wheel SAE
170 Horse
191 Torque


This is not without problems however. After the pulley install, during the dynos, you could see how the A/F was leaning, and the timing was cutting back. Buell, I know you have the experience to back up what you were saying about the engine. But mine was leaning out. I should mention that the K&N filter I ordered was not in stock, so that part has not been done. I thought this was an Octane issue so I got a bottle of LUCAS octane boost. So I made quite a few runs. This worked a bit, but after about 20 minutes of hard running, I find that the car is not powering up. I'm not sure of what is happening. But turning off the car and restaring quickly does nothing. HOwever, letting the car sit for 30 minutes brings back the power for another hard session of 20 minutes.

It was suggested that the power be unplugged. Hmmm. I don't konw that we unplugged the power. Before the meet tomorrow, I will unplug the power and reconnect as was mentioned.

Give me until Monday to put the video and dyno chart up.

Yes, when the car is going, it feels good. Cool bit of kick in the pants. Definite differance. According to Josh at HOP it could be possible to bring out 200 RWHP with headers and an exhaust. But I don't understand why my engine starts retarding the timing. Any ideas?


Ed

<---after my girl being patient with all of the install stuff and my bonzai runs & the meet and greet tomorrow, I'm banned from the board till Monday.

 

Sure it leans out, but it shouldn't be that bad, maybe 12.5:1 and it's only for a second. Your HP numbers look really low, could be the dyno you were on need calibration, I never got that low. Which pulley did you do, the add on ring or the aluminum pulley? Also, octane didn't make much of a difference, ran a dyno with 100 octane unleaded racing fuel, waste of money, zero gain.

 

100 octane didn't do anything because you don't have the ECU remap telling the car that the fuel can be different.

higher octane definitely helps in making more HP. Went to a open dyno run and 1 Supra ran 811rwhp with 100 octane mix and ran 7xx before he mixed it.

also, different dyno often yield different numbers.

 

100 octane would have helped for sure if there was any traces of pinging. If the car was pulling back timing because of the knock sensor, which it wasn't, 100 octane would have helped which it didn't. Back in the good old days of the 2002 c-coupe I tried everything and anything and backed it up on the dyno. Heck, even knocked off the muffler to see what that would do....

Now I'm lazy, happy with my completely stock M271 motor.

 

Haha, I know that feeling. Congrats on the install, good luck with the debugging.

Erik

 

Here is my dyno numbers

Buell, what mods did you have, just the pulley at the time? I have the whole aluminum pulley, not just the ring. I did a quick run to the grocery store this morning. Was running good. Now, to compare, I guess this is the best way I can say it. Feels like a Intake, Header and Exhaust add all at once. I used to have an 93 Integra that I did those adds to. I do like the increase supercharger whine.

So, after I disconnect the batter, and wait, isnt' their a restart procedure. Turn the wheel to the left all the way, then the right, then left again?

Ed

 

Yes, turn the steering wheel lock to lock until the message goes away, open and close the windows and sunroof and hold for a few seconds in the closed position. When that dyno was taken it was ASP alloy pulley and ITG filter. No chip, no headers, no exhaust, no 100 octane gas, no magic. Brandon from Kleemann got a comperable run on his alloy pulley although it was extrapolated based on altitude where mine was done at sea level. No reason any brand of pulley that is that diameter should produce different results unless you have something wrong somewhere. Also consider that if you do a few back to back runs without waiting 15-20 minutes to cool down the s/c and ic, it will get about 10-15hp less. Also wheels make a huge difference, throw some fat 19" wheels weighing 35+ lbs. and you'll probably lose 10-15HP.

 

Okay, now I'm also getting quite a bit of belt noise on startup. With some revs this goes away. I'm also getting TERRIBLE mileage. This is without me revving and getting on it.

SO, here is what I am going to try. I'm going back to a platinum stock plug. I'm going to check the tension on the belts. Try a dressing. I'll be ordering the K&N from Performance on Monday.

Again, when the power is working its quite noticeable, but I know things aren't right.

Ed

 

I never had a fuel mileage difference with the pulley kit. Never had belt noise of any kind and I removed and installed my pulley several times as the old timers here can attest to. Also, never, ever put belt dressing on a serpentine belt, really, never. My guess is that either they didn't put the belt on correctly over every pulley or they didn't put the crank pulley on right, didn't align the key and it didn't slide in all the way in and it's offset causing the belt to partially pop off. Definately remove the filter housing and take a very close look at it, driving it may cause more damage than your willing to pay for. Check my website if you need pulley installation instructions, it will have pictures of how to remove stuff.

 

Okay,

Spoke with Brandon at Kleeman. Great guy. He took the time to look at the dyno graph and do some thinking on why I'm down on power. Basically this likely comes down the an airmass sensor that is not right. The car is quite lean at higher RPMs.

From other dynos he has seen, people get somewhere around 200 horse, and 220 torque with that pulley. SOOOO back to the dealer to get that worked out. Once I get the car back, If I feel a differance I'll dyno again.

Ed

 

I thought I would just put in Brandon's followup email response.

Hello Edward-


Like I mentioned on the phone, baseline run looks lean as does the pulley run. I think you have a bad air mass sensor. Have your dealer check out the "actual values" of the MAF when attached to Star Diagnosis. Any drop outs of calculated air mass (example: going from 200 kg to 300 kg while smoothly raising revs) etc indicates a bad MAF.


Attached is a dyno from a 1.8 liter car, although this is not your engine, the bottom fuel line is what any MB should look like (we use lambda rather than air/fuel ratio). Note the drop in lambda from 3700 RPM and up:

Kind Regards-

Damn exciting graph for those of you with the 1.8 Liter engine!

 

This is a pretty simple install, take it off and do it yourself. Ive been running an ASP pulley for years, with no issues. Fuel mileage should be the same. The car should pull very hard, with a little more supercharger whine. 1st and 2nd pretty much disappear, you have to shift so quickly, its not until your in 3rd that you realize how much pulling power the engine has now.

 

Okay, I think I have the car debugged as far as power goes.

Here is what happened. The Supercharger seals were blown, putting oil back into the airmass and into the intercooler.

With only two days and 1,500 miles left on my 100k warranty, I took the car to the dealer for repair. The supercharger was replaced, as was the airmass sensor. The intercooler was flushed and cleaned out. The total of this work without warranty could have been as high as 4k!

I know what the pulley was suppossed to feel like. My mileage is unaffected, but their is quite a bit more power out of the car. I didn't quite get to put the car through the paces yestarday because of the rain here in So Cal.

The timing on getting the car fixed was unbeleivable. I was so used to the car, that I didn't know I had a problem. If not for the pulley install, I would have just continued to drive the car until the Supercharger gave up the ghost. Likely after my warranty period. Talk about good Kharma.

I do have to go back to the dealer. The alternator/Battery warning is coming on. I checked the tension on the belt, looks good, so who knows what it is.

I'm likely to get headers and and exhaust now. I'll prob get it before summer unless a great deal comes up quick. I'm probably going to wait to dyno until the exhaust install.
