Hey there. What is Doc Wilen Racing? Well, it is a hobby blown out of proportion. If it has to do with German automobiles, I am interested it in. I started in the business as the lead tech/shop manager and right hand for one of my best friends Stephen Kaspar (PorschePhD) for Imagine Auto here in Kansas City. For years we worked side by side and made it happen. The track and local business was my specialty along with 996/997 upgrade work. We built some crazy machines over the years that rivaled the best in the nation. Need 700hp out of your twin turbo? I can do that. Supercharge that 996 or 997? No problem. Suspension work? Corner Balancing? Yup, all easy. I don’t consider it a job anymore, but instead of hobby (though it seems like it at times) that is a good excuse to keep me busy around the house and at the track on the weekends, and allows me to do a little traveling around the Midwest during the season to some of the greatest race tracks around. Wow that was a long sentence. Based out of Olathe, KS, you can find me at tracks such as Heartland Park Topeka, Road America, Mid America Motorplex, Motorsports Park Hastings, Hallett Raceway, Brainerd International Raceway, and Gateway (RIP). I am also a nationally certified PCA instructor, so at the track I am usually out instructing with a student, or underneath a car 🙂

DOC WILEN RACING 
Karl,
It was a sad day when you guys closed the doors. You guys are still the best around. Are you still wrenching on 928’s hint, hint?
Thanks, Scott
Sure are 🙂 I’ll email you my contact information
nope, never heard of him.
Yo, Karl: Glad to see you are still workin on 944’s when you’re not doctoring. Like an idiot I just noticed your link when I was posting on kcws. Nice.
Wish I could make rentreffen this year, but no dice. I’m kinda afraid to drive my car very far from home knowing what you told me about T-belt replacement intervals. Thing doesn’t have more than 5 k on belt, but it has been almost 5 years.

As mentioned my 964 rear spoiler when in a down position just doesn’t look like its flush. The drive side appears to be higher then the passenger side when in the down position. I took it apart and nothing appears to be out of wack! Maybe thats to way its suppose to be? Also, my turn signal when making a right or left turn doesn’t automatically cancel after the turn. Can you fix that? If not I’ll just stop using my turn signals. Call me later this week.
Thanks

Hi Karl,
Long time since we spoke, but it sounds like Imagine Auto closed it’s doors. I am sorry to hear that and hope you are getting along ok. Looks like from your website you are having some fun workiing from home etcc.. …
I was wondering about a couple things I hope you can share your opinion on?
Has anyone every used Lucas oil treatment on our 951’s and or would you recommend it? I just thought it would be great to help the #2 rod bearing etc… I am using Vavoline 20w50 oil with ZDDPlus additive. I have looked around most of the forums and have never found anyone commenting on this.
I drive 4 -5 DE events at my local track and find myself having to replace my rear control arm bushing (castor block) currently it is the upgraded 968 version I am replacing and I am curious about the solid aluminum ones you can put in instead. A little more expensive but are they perminent? Also is the ride just way to harsh to enjoy street driving? Deutch nine has a nice one that enables you to put on a brace as well if ever wanted. Thnoughts?
Thank you and I enjoy your website Karl.

Doc,
Hello, I am a soon to become porsche 911 owner! I put a deposit down on a 1999 porsche 911 coupe. I specifically choose this car for 2 reasons. First even though it had 119K miles on the chassis it had a brand new M30 suspension 10K miles ago. The biggest reason though was because it had a porsche reman. engine put in it 23K miles ago. I read your article on IMS issues and the engine was put in in 05. Being that it is a new engine and put in, in 05 I shouldn’t have any issues with IMS catastrophic failure again right? Please, if there is any way I could call and ask you a couple questions it would be much appreciated. I’m really nervous over this purchase and I think it is b/c I have allowed the internet to scare me (like looking for a symptom you have when sick on Web MD or something, it will make you think your are dying). Anyway please email me if at all possible at cfiiman@hotmail.com and if you had just a couple of minutes to speak on the phone please just give me a number I could call. I really look forward to any advice you could give me, thanks so much!

Karl,
I live in NYC and I was wondering if you can recommend a very good Porsche tech like yourself?
TIA,
Diesel
Hi Diesel,
Sorry about the late reply, somehow this one slipped through the cracks. How close are you to Blauvelt, NY? Deman Motorsports is out there and is a pretty good shop.

Hi Doc, I have been reading your posts from 2009 on windows issues, I have a 97 boxster and my passenger window has stopped operating in full, when you open from inside or outside or roof lever nothing happens, any ideas??
Cheers Nick
Nick,
Not sure if I replied or not! If it doesn’t work with the switches at all (window switch), then I would look at the motor itself. If you can operate it with the window switches, just not with the door handles, I would look at your door latch assembly.
