Alright fellas so I got my cm stage 3 kit with alum flywheel installed in my car this week. Shop calls me and said car barely idles and is running way rich. They go over all ic and vac hoses and say everything's on good no sign of boost vac leak. I go over there to reflash car thinking maybe ecu got reset or something. Reflash car try starting same outcome. They said they'll remove trans again and see if they can find anything wrong with install or flywheel. Get a call this evening and they said they found the problem. Apparently the trigger wheel is not set to the right position and timing was thrown off. My question is, is this the fault of cm not installing trigger wheel in proper position or is this something that should get checked normally from the installer/shop to make sure it's in proper position? I just don't want to be stuck paying for labor of removal/install of trans twice. Now this is a reputable Porsche shop I'm having work done at they work on race cars and street. Any input from DIY guys and shop owners/mechanics would be greatly appreciated! Thanks in advance!

 

Gotta pay if you wanna play!

 

^ your comment was of no help.

I haven't read any posts with this issue so I'd have to say the shop should be responsible with installing it correctly especially if they work on porsches for a living.

 

Sorry if you don't like the response. The reality with modfied cars is that you, as the owner, are resonponsible with the direction of the car within reason. You only provided your perspective of the ongoing modifications with blame in one direction. When you modify a car beyond its original intended design, you assume the risk. Getting into a battle with a shop making modifications that you request, on a platform not designed for your intentions, is absurd. Suck it up and deal with it, unless you can prove they are inept for their prescribed business.

 

I would think that any shop doing a flywheel replacement should make sure the trigger is aligned properly. I certainly had no such problem when Speed Gallery did my LWFW.

I did pay them to remove the LWFW a few months later because I hated the way the car drove.... but they didn't force me to get a LWFW so that's to be expected

 

Here is the pic with old and new. They marked dowel pin and trigger wheel angle as you can see how far off the cm flywheel is off from proper angle compared to oem. My question is should the flywheel have been set properly from cm or is it common practice for shops to check correct angle/degree of aftermarket flywheels?

 

Its a pretty simple thing really. Just bolts right in. I would bet that it wasnt miss aligned as much as they just forgot to re attach it.

 

How am I supposed to know the flywheel is not set at correct angle? This is my fault? I'm not the mechanic or manufacturer. See pic above. If you buy a part for a car you expect it to work properly for the intended model. This is not a case of me buying a set of aftermarket wheels and me putting on a wrong tire size that causes fitment issues on the car I understand something like that I would take responsibility for as it would be my fault for improper fitment/compatibility.

 

opps .. sorry disregard my post. i was thinking something else

 

Sounds like they assumed it was identical and did not ck the part prior to install.Pretty clear its a defective part.Anyone who does repair work daily knows new defective parts are out there,and with as big a job as a clutch/flywheel is-ck the part before installation-esp aftermarket.If the shop does try to stick you with additional labor,I would contact the flywheel manufacturer & see if they will step up for the addtional labor.Either way the shop and part man. made mistakes

 

If they are full time Porsche mechanics then I would say they made the mistake and should be responsible for the extra time it took to correct it, not you.

 

I don't know the step-by-step details of the LWFW install, but if the trigger wheel was touched at all during the installation, then it's the shop's fault. You paid the shop for their expertise so they need to fix the issue on their dime.

There is always risk involved when any shop does work...even oem. I would ask questions every step of the way. Even then it is hit or miss...good luck...

 

You said the shop that did the work was "reputable". I would only use that term if they stepped up and took responsibility for their work. You brought them a working car and asked them to install a part that was made specifically for your car. Once they accept the job, it is their responsibility to return the car in the same condition as it was when they accepted it. Obviously if something does not work after they mess with it - they need to fix it and return the car for the price originally quoted for the work that was done. I am self-employed also and that's how I deal with any issues.

 

Back when I had my race shop we did a nice 632" supercharged engine for a high dollar pleasure boat that was being made for the customer. We dynoed the motor, packed it and shipped it off. These motor are internally balanced and require a zero balance flywheel, this was noted on the invoice as well as the tag on the motor.
Well anyway they (a VERY reputable boat builder) install the engine with a improper flywheel for a externally balanced engine. Boat goes out the door, get run for 20 hours or so and the flywheel shears off its bolts, taking out the bearings and doing damage to the aluminium block.
Upon removal and inspection the error was easy to spot and the boat builder stepped up and paid in full for my rebuild of the engine, as well as shipping to and from the shop,dyno time and all other charges incurred.
When I ran my shop the tech was expected to check every part used and to make sure that part was correct for the application, and double check it if the part is brought in by the customer or something we do not normally use everyday. If we missed something we fixed it on us...period.
Now I will say that if you bring in a part that you want to use, and it fails, well then the "pay to play" applies of course, also if we are building any type of risky power level engine is on you as the customer to accept the risk.
IMHO in this case I would think the tech would always check the trigger position as a matter of course, first rule of high performance parts....never trust anything to be spot on, check everything no matter what.
