I had the K2 with LSD put on my 2004 back in early Sept. I have been trying to get good numbers out the mods. I did my 4th dyno today and am getting 443 rwhp (uncorrected) which is 428 rwhp (corrected). Going with Kleemann's factor of 19% loss in the drive train that equates to 527 uncorrected at the crank and 509 corrected. This is after a second computer programing.

Can anyone who has done the K2, PLEASE post what numbers you are actually getting so I know where I am at?

I know there are posts out there but when I did a search for K2 hp is was all mixed with talk about getting K2.

Kleeman claims I should get about an 84 hp increase but I'm not seeing it. Oh, by the way the installer did not do a base line on the car before install. They said they had no time.

Thanks!

No time? I thought you were the customer. They should do whatever you want/wanted. They had the time to take your money, didn't they?

hydeaway

where did you go to get your Mods?

I got around 440 rwhp on mine but I have the EVO headers instead of the Kleemann. Also, my air inlet tubes were not fully connected so who really knows with my car. You should make more hp with the Kleemann stuff, just not sure if it's that much more. I think for the most part I've seen numbers around the 460 range.

quick question....have you tried another dyno? Sounds like this installer is shifty to be too busy to do the basics. Wow. Yeah,pretty low for K2 car.

Hate to say it bur perhaps car trouble. have you taken it in for service since then.....wondering if they reflashed the ECU back to stock. Other than that perhaps trying reset ECU by disconnecting negative terminal for 30 mins then beat it hard for 15 to 20 up and down shifts. Should set u up more aggressively timijg wise.


Good luck.

This is my Dyno before and after K2 plus LSD. This is not RWHP but it shows a 100+ increase in HP. I also confirmed this power increase at the track, my trap speed went from 114 to 123mph.

I assume you have contacted Cory? I am sure he will be of some help.

Willow Automotive in Chicago installed everyhting. This ended up being the WORST car related experience I have ever had. They were great before the sale and then offered sh*t for post service and support. They also caused $6200.00 worth of damage to the rear end of my car. I'll post that story another time.

When I brought the car for install I requested a dyno but they said the time frame I needed the car back in didn't allow for pre and post dynos. I now believe that to be BS.

I have had the car dynoed at three different locations and have had the Dealer check the car three times. I don't know if there is something to specifically look for. I don't even trust the install job now to even know if it was done right.

I have talked to Cory many times and he even suggested for a final repair to my rear end that if he were me he wouldn't bring it back to Willow.

For the gian in hp, right now I'm starting to regret doing this.

What you guys have said seems to support that I am not getting the hp I should. Any more suggestions?

Rock

Sorry for your misfortune. I hate to hear these type of stories. I wish I had good advise for you...................oh............ I do know a good gun shop (JK).

For others considering Kleemann modification, I strongly advise you to ship your car to Colorado Springs. For a few extra bucks you will sleep better at night, knowing that the masters have taken care of your $100,000 car.

Sorry for your problems. I had the Kleemann K4 installed just down the street from Willow and I was putting down really low numbers on the dyno. I have gone to the dyno 4 time with a total of 11 pulls and I still have the same results ~450rwhp. Both Kleemann and Knauz have been good to work with sofar and they just found out that the waterpump on the car was completely shot. Hopefulley that will make a big difference in power now. Send me a PM if you need in more info with Knauz, I may be able to help.

What type of dyno was this on? If a dyno jet then maybe possible, mustang dyno should be higher (1-3% in my experience).

I have a mix in mods -- see sig. but basically K2 w/ LSD + cutouts and I am laying it down. 700 crank torque and 600 hp

I have to agree with you Rock, I would without a doubt have taken it directly to Cory in Colorado. I got Willow's name from Kleemann's site and thought it would be nice to build a relationship with someone local. Next time I get mods done on any car it will be from the makers themselves. It wouls have been less expensive at this point to have shipped the car not to mention my car was in the shop an extra 30 days due to the damages. Rock, your numbers are a dream.

I had one dyno done on a Mustang and 3 done on 2 different Dynojets. The Dealer changed my water pump just to be safe to try & help me out. The dyno guys thought maybe I was leaking boost pressure. Has anyone ever tested before and after boost pressures? Would you be able to tell if you had a leak without putting a gauge on?

I almost took my old C320 to Willow for the KLEEMANN supercharger. I backed out coz they became somewhat defensive when I asked about their experiences. I believe people had a little better luck with Knauz though

It would be very helpful if you could post one of your dyno graphs. Also, from the sounds of it, this low power is either attributed to very high IATs or an Air/Fuel ratio that is out of whack.

Firstly, if you could post the graph of your latest dyno we could tell if Air/Fuel is an issue. Secondly, I would recommend you either purchase a datalogger (very handy to have) or get a friend to come with you and datalog a WOT run on the highway. If your IATs are over 140 I would suspect your intercooler fluid pump is bad.

Do you have the upgraded Kleemann fluid pump or just the stock one?

You know, I did call Knauz and I thought Willow seemed better. Boy, talk about a mistake in judgement! Live and learn.

i have talked to willow and knaus and was about to go get my K2 upgrade at willow also. Im not so sure if i would get them now. I might check Madison WI K dealer.....

Anyone have experience (good or bad) with this dealer?

I lived in Madison for 7 years and bought my C320 from Zimbrick European. John was my SA and he has always nice to me. However, they've only recently became a KLEEMANN dealer so I'm not sure how experienced they are with the mods.

I have the same problem. Did the k2 and lsd a few weeks ago. When I first got it the thing was a complete beast, but after about 25 miles the check engine light came on. So took it back to the installer and had the ecu sent to kleemann USA. Got it back no check engine light, but power seemed way down from the previous ecu. Took it to a dyno and had 452 rwhp and 464 rwtq. I know it wasnt a dyno error because my friends M5 dyno came in at exactly where it should have been.

hydeaway

After reading alot of post here it seems that alot of K2 upgrade has a check engine light. Is this normal if you do get the K2 upgrade?

Rock

I have never had a check engine light. I think it may have to do more with who completed the install as opposed to any inherent K2 problem.

dsc

I didn't have a check engine until after 300 miles when it was discovered that they speed sensor wasn't mounted properly and fell off into the wheel which resulted in it's destruction.

Vrus, thanks for the offer I'll post the Dyno sheet soon as I figure out how.

spectre55

I think people who had the newest version of the ECU had the check engine light problem. Not sure though.

MG0427

I totally agree with ROCK,

I just dropped of my CLS55 with Cory at Kleemann, to tune it properly in person, and get rid of the check engine light. He is also going to Dyno tune it while its there.

Cory is great and has been very helpful. I will put together a full report by the end of next week, when I get the car back with Dyno graphs and video.

hydeaway

Called John and left a vmail yesterday (early afternoon) and i didnt even get a call back yet. Sending my car to Colorado is looking better and better.

dsc

OK, if I did it right here is one of my current dynos done on March 3rd. Conditions were: Temp=50 degree, Humidity=39%, Bar. Pressure=29.26.

I have a brand new Mercedes replacement IC pump. The primary cats are removed so all I have are the secondary cats in place. Cory said that this should have given me even more power.

Can you tell me what is a good datalogger brand and where is a good place to it?

I'm looking forward to any comments, thanks.

Sorry, here it is.
