Methanol injection and Nitrous installed

[bcredliner]

Well, against advice, caution and reason I have added methanol injection and a 150 shot of nitrous to my X5 4.6 that already had Dinan cold air package, throttle body, air flow meter, stage 4 engine software,transmission software and free flow exhaust. I did decide to have Stett Performance, a local BMW specialist, do the install to eliminate some of the risk.

It was well worth it!!!! I am VERY pleased with performance!!! Launch is amazing with some tire spin and it just gets stronger and stronger through the gears. Will do dyno runs in the near future to document the gain with just methanol and then with nitrous boost. With methanol and nitrous I should get around 165 gain in HP and will have to see from dyno runs how much torque gain.

Control for the methanol injection is in the glove box as control is seldom used. Controls for the bottle heater and nitrous are in the center console where the CDs store. Methanol tank is in the right side panel in the back when the sub woofer used to be. Methanol pump is behind the trailer hitch cover plate. Nitrous bottle is exposed in the back cargo area unless the cargo cover is extended. Nitrous purges through vents in front of the windshield which are visible if you know what you are looking for under the hood. All else is pretty much hidden though stealth was not the goal. System is set up so that Nitrous won't fire unless there is appropriate methanol present. Methanol system is active on demand in daily driving. Demand can be adjusted with controller. Since methanol is there without the nitrous there should be some gain in mileage and performance without nitrous. So far it looks like I am getting about 2 more miles to a gallon though some of that cost reduction is lost due to cost of boost juice. Nitrous system is a NOS system. Methanol injection is from Snow performance. Engine sounds deeper under acceleration with or without Nitrous.

Will update when dyno runs are complete or if there are any problems that occur.

your missing one thing besides dyno...WHERE ARE THE PICTURES AND VIDEOS?!?!

[bcredliner]

I will take some pictures though haven't posted pictures before so will need to find how to do so.

Wow you are crazy. We need to see a vid of it hauling ass.

First picture shows Nitrous Express tank in back with Snow performance bottle in side compartment. Hatch cover fits in place as usual.

Second picture is of the console where the gauge, red purge button and toggle switches for activation of nitrous and bottle heater are located. LED lights when methanol is empty.

At the top of the third picture you can see the purge plumbling.

Fourth picture is the methanol controller in the glove box.

Fifth picture shows the metanol pump which is mounted behind the trailer hitch cover. Hatch cover fits in place as usual.

That is indeed awsome! Im just curious as to why you chose to mount the meth pump in that location??
