My intention is to give an objective review about my experience with Hahn RaceCraft and the installation of a prototype turbo for a 2.4 Chevrolet HHR. There are photos of my engine compartment and general performance numbers posted here and elsewhere.
For exact dates and details, please refer to my timeline and the pdf’s that I have posted. You will find more information than is needed for a simple review there.
I’ll address the system itself first.
Looks:
The quality appears to be outstanding. The piping and intercooler look great. Aaron did a very good job of polishing the front of the intercooler and the pipes really pop under the hood in the red. Based on looks alone, I am very pleased.
Performance:
This is a difficult area to address because of the tuning never being completed. I can tell you this, it compares very well to when I was running a 75 shot through my ZEX set-up. The difference is that the power is constant. There are some issues around 4000 rpm’s which will need to addressed, but I don’t see this as a major issue which can not be fixed. I do get an occasional CEL light. I originally had three; two related to the transmission, the other for running lean. Once I replaced the TCM and had it flashed to stock, those codes went away. So I’m just running lean once in a while.
The shift points will probably need adjusting too. Really I think all of the performance complaints I have will be addressed by a proper tune.
Customer Service:
This is the area where there is an almost complete failure. My car was in the possession of Hahn RaceCraft for 277 Days (39 Weeks and 4 Days). I understand that The Hahn family experienced great personal tragedy during the year and I was as patient and understanding as anyone could be. However, my primary complaint is that that should not have been used as a way to explain away a project which was originally to take three months and that after it was slightly scaled back was told would take 2-3 weeks once work began. Little, if any work was done for the first several months my cars was there.
If there had been frequent, honest, open communication much would have been forgiven. However, I was constantly told that work was progressing, given an expected delivery date; only to find out as the day approached that little had changed. Over the course of events I stressed several time how important communication was to me.
I won’t detail all of the instances of wasted time; those can be found in the other files I have posted. I will however give two blatant examples.
The ECU’s in my car had an aftermarket tune that Hahn RC knew about. I even made arrangements for Tune Time to put them back to stock. However, Hahn RC did not send them off until eight months had passed. The car sat for over two weeks waiting for them to be done so that tuning could start.
My car also has a custom bumper. In the original discussions this was a concern shared by Bill Hahn and myself. For that reason my wife and I drove both of our HHR’s when we were to drop mine off so that Bill could take measurements and photos of a stock HHR. The first thing to be done was too remove my bumper and test fit an intercooler to determine in my car would work. Hahn RC needed a configuration that would work on stock 2.4’s also. The bumper was not test fitted over an intercooler until the weekend before I picked up the car. Because of this the intercooler had to be repositioned and further modifications had to be done to make it work.
As for how I was treated personally……..Aaron was always very respectful. Bill Hahn was not. I was often made to feel that I was not allowed to express any frustrations because his personal issues trumped them. This happened on more than one occasion. I asked over and over for updates about what was being done. At different times, I was told by Bill Hahn that he would have to “train” me to understand all of the “nuances” and that he didn’t have time for that. He also told that because of all of the technical aspects that I wouldn’t understand, all he needed to tell me was when my car was ready to be picked up.
Overall reflection:
If I had to do this again, I wouldn’t. I place much of the blame on myself for not keeping accurate records of early phone and private message conversations about the project and never getting anything in writing. I will not make any conclusions on the project or about the people I had contact with. I am just stating what happened and how some of it made me feel. I will not do business with Hahn RaceCraft in the future.

In it, we'll also address why you and your friends are so interested in tearing me down that you'll suspend any benefit of the doubt for me in favor of taking the word of a complete stranger. A complete stranger tells one of you this story, and without hesitation, you all are ready to tear down a member of your fraternity (me) that's been supporting your car platform for years. There's something very wrong with that, and we're going to find out just what it is

Bill Hahn Jr. wrote:Not that you're going to catch me in here, no. Lying in public can have nasty repercussions, especially when it can affect one's livelihood. Even more so when it's a technical art that's been passed down over the generations. It may sound corny, but I would never risk bringing shame to the Hahn family name. My late father's memory, and dignity, mean far to much to me.
I need not lie about the technology I have devoted my life to. I have a lot at stake. If I lie here, I risk it all.
Nonetheless, you know what you have to do now. Prove that I am lying. And do yourself a favor... stop feeling like my expert status belittles you. It's not even ABOUT you, lol!

Edgy territory you're on there, sir. As with John, you've officially impugned my reputation now, accusing me of lying about my business in a public forum. You've offered no evidence to support your accusation.

Bill Hahn Jr. wrote:You miss the point. I am talking here only about my business. You've accused me of lying about it. Standards of libel are fairly straightforward in that you can say just about anything you want in public, so long as it's true. As you've accused me of lying about my research, and my product, you may well be called upon to back up that accusation. If you can prove its true, you are in the clear. In order to do so, you will have to prove these following points untrue:

Bill Hahn Jr. wrote:From now on, the record will be set straight, and the facts laid bare for all to see. Both sides will be represented, and if my greater skills mean my side is better represented, then all is as it should be. No matter whose feelings get hurt. If you don't like it, then I suggest you don't come looking for it.

Bill Hahn Jr. wrote:Mike's got a genuine beef with us, and for his trouble and inconvenience, I am truly sorry. I had, and still have, every intention of finishing this project. I have tried. Mike refused to bring it back to me when I asked him to, saying he feared losing it for more months. I tried...but it would appear that under the circumstances, I just didn't try hard enough. My latest trip back to Florida was delayed several times (I was going to stop and visit him and the HHR on my way) and I had been unable to go to
Mike's area until earlier this month. When we then made phone calls and emails to arrange to work on it, they went unreturned.

your banter is being ignored here buddy. Bill hahn is a stand up guy. I feel bad I've never purchased anything from him, but I will stand for his character and integrity.
