A little birdy told me that BMS is going to start working on a meth kit for the 335d in the coming weeks.

Possible release date? Cost?

Stupid question, but with more power at our disposal won't this meth addition run the risk of blowing the transmission? I mean with the JBD we are already at approx. 520 lb/ft torque right?

[DSB335d]

The only safe way to do this would probably have to be in conjunction with a custom tune.

That is a valid concern. Certainly this will not be for everyone just as running a tune is not, although this does take it to the next level. Personally I have been dieing to see a meth kit come out for the d, diesels respond very well to a water/meth injection or even just distilled water.

I suspect the transmission can handle well in excess of what ZF has it rated at. There are countless 335i's running around putting out hp and torque numbers far in excess of what their car's tranmissions are rated for and their tranmissions are rated much lower than our d's. Another example although more extreme, take a look at the new Vishnu 335 rated at 627hp, it still has the OEM transmission.

How is that?

Running a water/meth injection can be done in reasonably safe manner so long as the mixture ratios are right. Meth is like nitrous for diesels. Water/meth kits are quite popular among the diesel truck crowd for not only producing a few extra ponies but to reduce EGT's.

I understand how it works. the jbd and software tunes are already close to the claimed limits of the d's transmission torque rating adding meth could possibly run the risk of breaking something.

Thanks. That Vishnu must be a beast!

A beast is an understatement.

Nobody is claiming tuning does not come without risk, quite the contrary.

Given what I have seen and more specfically what these ZF transmissions can handle I am not concerned about a few extra ft lbs of torque. The water/meth kit will likely add more hp's and it can be delivered in such a manner that we might be able to add more hp up top where the d could stand to use a few extra to compensate for the taller gearing. Shoot I would be happy with the benefits of running just washer fluid.

Interesting development. I was wondering how long this would take.

Here's an article on water/meth injection systems for diesels.

I'd be interested

Chris, thank you for finding this information and keeping our education up to speed!

This article makes it sound like adding injection would be all that is necessary to boost our engines, rendering a tune unnecessary.

Something that didn't appear to be addressed is what the EGT's did at the various enhanced performance levels. Also, it doesn't appear that the truck had our level of emissions system; I would be curious to know if there would be anything in the injection fluid and its results that would affect our emissions gear, either positively or negatively.

Thanks again for your research, we all benefit from your efforts.

Hey no problem Joseph, it's fun for me! Just trying to do my part to progress the "cause." Water/meth actually works quite well in conjuction with a tune, but you are right, one should see some decent gains (engine size dependent) even without a tune.

I guess this would have been the better article to post first.

You may find this interesting as well.

I reached out to Snow Performance as well. Arguably one of the leadering manufacturers in this segment.

Dam.......I'm really at a loss for words right now. Simply amazing!

BMS meth kits are the best! I'd love to own a 35d with meth.

[Julesandtrish]

. I'd like to know as well.

[cssnms]

Take a breath guys! This news was hot off the presses. R&D isn't going to start for a couple of weeks, so it will take some time.

Snow Peformance believes their meth kit would work on our cars too. They are looking into it and will get back to me.

I never heard of a gearbox failure in our cars due to power increase. My car has the ZF 6HP26 (600nm limit) and put down in the last dyno 404hp and 833nm on a MAHA LPS3000 considered by the experts as the most accurate dyno. After that, the IC piping was improved (complete 60mm stainless steel piping with EGR and butterfly housing bypass) followed with a little ecu tweaking.

The gearbox is just a bit sluggish on upshifting at wot because it revs pretty quick and hits the redline a lot stronger than stock, but at manual/sequential shifting it is normal.

The gearbox has over 100k miles with the torque above the manufacturer limit and never had a problem but the oil and filter is religious changed every 30k miles.

It is insane the potencial of these engines. My turbos is still stock and i can keep up already with very fast cars like a stock Porsche 996 turbo. I'm curious to see your results with the WMI.
