Methanol Injection pro's and con's
Hi Guys
I would just like to ask everyone. When is the right time too consider having a Methanol Injection Kit installed ? And what are the Real World benefits for everyday Driving What are the running cost's involved ? Does it pose any problems / dangers to your Engine ? Can it be a problem when you have to get the car serviced at BMW ? I am driving a 2006 BMW 335i coupé N54B30a with ECU 366 Bhp remap , Quaife LSD , Sports Catalysts , Birds B3 Suspension , Birds Anti Roll Bars , Alcon Front Brakes. Been thinking about getting the Birds upgrade Turbo s and 430 bhp Ecu remap and want to know if I should bother looking at getting the Methanol Injection Kit and who is the best Company / supplier to deal with in the UK for fitting it. Thanks Guys Ross |

When is the right time?
Before you consider upgrading the turbos. If you have a procede tuning device fitted by birds then you should get the Vishnu Meth kit to use in conjunction with it. If not you'll need a piggyback device to control the flow. Pro's: Chemical intercooler Boosts octane Allows you to run more boost safely (and reduces the likelyhoold of knock events) Steam cleans the engine (including intake valves) Meth is very cheap (I bought 100 litres for £30 - will last years!) Cons: Fire hazard (get a tank in the boot and decent lines/fittings) Insurance impact thats about it.. Best supplier - DIY (so you can problem solve the problems) alternatively Devils Own UK distributor.

Thanks for the quick reply. I had looked on the Vishnu website as I believe you are correct and it is most likely a procede tuning device. I take it the Vishnu kit will be sent from the USA ? I can definitely see a lot of good positive results from running the Meth/water kit and there are just a couple of more questions Phil. Did you buy any more after market parts / components too help the kit run smoother or indeed compliment the performance. And where exactly do you source you're Meth/water mix when running low ( devils own ? ) I'm guessing it's good for at least a few hundred miles ? Thanks again Phil your help is always appreciated mate. Ross |

Vishnu kit for the meth pump, integration equipment and failsafe (I use jb4 for this so not familiar with Vishnu kit). Jeff at topgearsolutions may be a good bet for advice..
Devils own uk for the tank, nozzles, SS lines and connectors. I got lucky and bought 99% methanol from a farmer relatively locally via eBay. He had the remainder of a 1000l carton to get rid of! I bought from bonnymans before this (£50 per 20l iirc).. With JB4 Meth only flows when you are on a meth map (map 3), over 2,500rpm and WOT. Hence if you drive sensibly most of the time 5litres of mixture would last a month easily enough. I run a 50:50 mix of meth to water (by weight) for safety. 80:20 would be better for max power but I still have a WW kit. Factor in clutch slip if you have a Manual. Even with stock turbos I made 512lb/ft of torque on the dyno (With a boost leak!)! My new clutch (spec stg 2+) is inbound. Ancillaries you'll need at a minimum: Chargepipe with meth bungs (avoid BMS cp). If considering new turbos go for a cp with two meth bungs. Forge diverter valves? To go with the above - a dump valve can be dangerous with meth. Stock DV's are liable to leak at high boost pressure but you can do without these until the stock ones leak..

Thanks a lot that is some fantastic information very much appreciated mate. I think nearer the time I will contact both Jeff at topgearsolutions and the guys at Devilsown uk for the advice they can give. The ancillaries I will source separately with a view to whom ever does the installation fitting them along with cheers Phil. I'm driving an automatic with paddle shift sports manual option so hopefully there won't be any issues regarding the clutch. You've got some seriously impressive figures on dyno and all that with a boost leak phenomenal. Thanks for all of your advice I'll keep you updated if I go ahead with the modifications.

if you get a trunk mount then the odds of a fire under the hood is alot less likely. But if your using your Windshield washer reservoir for the meth, then you will have to keep a closer eye on it to ensure you never have any leaks. My biggest inconvenience is going to the shop that is across town to buy my meth and making my own water/meth mixes... but to me its worth is. Plus meth helps keep things cooler and cleaner inside the engine and fights carbon build up i believe. And if you take your car into BMW for regular service/repairs they will work on your car but if anything major breaks don't look for them to honor any warranty that you may have. im pritty sure this will void your warranty and you would have to pay out of pocket for repairs...

American fuel has different ratings to the stuff we buy, they have 91 as you state but also 93. This isnt RON it is octane which is the same as the stuff we get ripped off for lol. 91 is equivalent to our 95 93 is equivalent to our 97

Even running race fuel, meth has a big impact on performance due to its ability to cool intake air temps. Cooler air = more safe and reliable power.
The more boost you want the more heat the turbos will generate. It's quite startling how well meth zaps the heat - better than any fmic on the market!!

Flip, makes me glad its only a driveshaft Im taking out rather than a gearbag! Still knocking away yep, no louder or quieter despite about 500 mile on it now. And the M3 Diff is in need of the friction modifier as its clutch plates haven't fully broken in yet or are too tight, and its making the common rubbing sound to a lot of M3's. Quicker we can get sorted then the quicker we can get meth!! |

Will now look for a meth kit as well although I may have to lose the dump valve?

You should get downpipes before meth..
Thats the biggest restriction at the moment, you could have the DP's swapped as you change the turbo vacuum hoses..!
