Installed Meth in 335i...!!!

Just finished installing the meth kit from BMS along with their charge pipe and connected everything to my already installed JB4. If anyone has any questions on doing this let me know. I also installed a custom made steal charge pipe that has the methanol line fittings. I saved the old one for warranty service times and was surprised to see how much oil dripped out of that thing when I removed it. Hence, I ordered the oil catch can and will install that next.
I did a trunk mount pump and meth tank and ran the lines from the trunk through the firewall. I do NOT need any more power for this car as I'm sure I would need a new rear end at some point. Cool thing is you can turn the methanol flow off via the JB4 controls to conserve or only use it when you want (I might turn it on here and there now but usually conserve the methanol). The car literally hops when I step on it and jumps forward at low speeds. At high speeds it now has that high end power you seem to lose after 3rd's last good good pull and going into 4th's low pull cruising gear.
Wasn't the hardest thing to install but for a first timer, wasn't the easiest. Could now do it in 2-3 hours I think.

Regards,

SP

Mein Auto: 2007 335i
Being a relative newbie to the BMW world, I have questions about these performance mods.

Does adding JB4 (or equivalent) and a tune shorten the lifespan of either the engine, the turbos, or both? What about other drivetrain components? I am curious about whether BMW conservatively tuned the engine at the moderate amount of boost a stock 335i provides and adding another 5 or so psi is something the car is easily capable of handling. I see lots of positive comments regarding the performance of mods, but little information on long term effects. I bought my car a few weeks ago (2007) with 64K on the clock and would like to see at least 100K without major issues. I understand that things break, but I don't want to exacerbate things unnecessarily.

I'll let you know when I get to 100k! I have had car into dealer for engine issues with JB4 installed and they took care of everything. I just turned the tuner off. For the meth, I'll simply pull it out before going in.
I'm at 48k right now and just drained/refilled my zf tranny fluid.

Im not the expert here but i dont believe it will shorten your cars life as long as u take care of your car by doing your regular maintenance, making sure u warm up the car all that little stuff plus JB4 has a map that can detect if something is wrong with your car and it will switch back to stock by itself

I just installed it a couple weeks ago still tryna play with it.

It can definitely increase part wear. But as long as you maintain the car properly, you won't see this wear affecting your car anytime soon.

If you're like most people, you will probably be in a new car before this wear catches up with you.

I also installed a new charge pipe (from BMS) that has a meth line nozzle fitting on the top and bottom in place of the original charge pipe. You don't need to do this but the original does not come with a hole (and is plastic) but you can easily take it off. There is a flat side on the original pipe that you can drill and tap and thread the spray nozzle into if you want. You can also buy an elbow that attaches to the original that has a fitting for around $60.00. I saved the original in case I have any issues (and can quickly resintall) since I'm under CPO and may have to take in for warranty. It looks like it may be hard to put in once it's in there but it was probably the easiest part of the job. I don't have a pic of the line running to the pipe as I did that later because feeding the power line and meth line thru the firewall had me perplexed at first. Once I figured it out, it only took me about 20 minutes and the line is ran through the inside of the car from the trunk thru the firewall and is all hidden.

Yes you don't have to take it off. You can turn it off whenever you want i believe even when your driving. It wont void your warranty if you still have it

Simply having something in or on your car does not void any warranty. You could drop a nitrous oxide system under the hood and wheelie bars on the back and it does not void anything.
However, and this is crystal clear, if you have an issue and there is any way that the dealer can associate your problem with your modification...bang, the warranty is over in regard to that issue (only).
So...in regard to the OP...if the dealer is aware he has meth, and somewhere down the road he blows oil, burns a valve, or cracks a piston, or his turbos start to rattle...guess what value the warranty will have? Zippo.
Those who modify their cars need to man up and know that if they want to play, they gotta pay.

The law (federal and state) is quite clear on this. The dealership would have to be able to prove that your modification resulted in the subsequent problem. They would then have grounds to deny your claim that a repair should be covered under the warranty.
For instance, let's say that you install nitrous oxide and on your third run that day at the dragstrip you throw a rod. Your engine is toast. Don't expect the warranty to cover the new engine. Let's also say that at the end of the day you noticed that your driver's seat seemed loose. If the dealer claims that was caused by excessive G-force that would seem unsupportable, but maybe not. Let's also say that your radio stopped working. Doesn't seem likely they can say you caused that to happen by adding nitrous.
The thing is, the dealer can deny your claim and say it's voided by your mod. You would have to take them to court where the burden of proof would be on them to show that your mod caused the problem. That's a heavy burden and if it gets that far they might find it cheaper to settle. Meanwhile you have substantial legal costs which the settlement may not cover. Is it worth it? Depends.

To answer your specific question (If) u put aftermarket exhaust to your car? Now thats something you cant hide to the dealership would that void your warranty right away? No, it voids absolutely NOTHING. If later you burned out the bearings in a turbo, could they claim that it was a result of your new exhaust? Yeah, they probably would. Are you prepared to pay thousands of dollars in legal fees, and wait maybe years, to make them prove it in court?

One other thing. When you bought your car did you read the fine print? Almost all contracts now read that any dispute MUST be settled through arbitration. Good luck with that.

Correctomundo. It is not right to trifle with the engineering and then expect the manufacturer to cover the damage probably resulting from your mod's.
Other than that, have fun!

Meh. Only if the law of the state where the car was sold provides for arbitration of disputes. CA generally does not recognize contractual circumvention of its Business and Professions Code. There are some sections of the B&PC where arbitration of disputes is provided for. But all other (non-excepted) issues can not be compelled to arbitration by contract. This matter has gone up on appeal (published opinion) and the CA Supreme Court declined to hear the appeal from the Appeals Court decision.
