View Full Version : HPF Methanol On/Off Switch Now Available

Many customers with our stage 2 or higher turbo kits have wanted the ability to turn methanol on/off with a switch rather than have their car automatically use it when it's needed. This allows a customer to drive full throttle without methanol being used and then flip a switch when they want more power. This conserves methanol and allows them to ensure they always have methanol in their tank.

We originally gave our customers a schematic that allowed them to wire in their own switch. This design turned the methanol pump off and told the EMS that methanol was not to be used. This wiring schematic did not turn off the methanol fogger however and ultimately when the customer would go to use methanol again it would sputter and the methanol line would need to be purged before a clean pull could be done. We also had several customers mis-wire something which resulted in HPF support to get their cars fixed.

After using and testing all the switches that customers put in their M3's and dealing with the wiring issues, we decided to create a switch that was entirely plug-n-play, durable, easy to see whether it was on or off and simple to install. One that was shielded, the right length, and had the switch labeled. This new switch also turns off the methanol fogger nozzle so no purging is required when the switch is turned back on.

Here's a link to the new part...

Chris,

While it would require an additional wired connection or two, you might want to consider offering a rocker switch that has a LED indicator. They allow the driver to determine the status of his methanol switch at a glance and in all lighting conditions.

I agree, a swtich which can be see at night that also matches the lights in the car would look perfect!

That's a great idea however it would require a 6 pin connector for us to get the power to it for the LED as well as all the other wires. Customers will easily be able to tell which way is on or off with our setup and the label. :)

Ordered mine today.. wondering where is everyone planning to locate the switch? I will probably put mine out of sight.

I dont have the actual HPF switch, but just one I made up and when I get my car back from HPF ill post some pics of where I put my switch. Its mounted in the ashtray so when the ashtray cover is down you dont see it for the stealthy look. I still need to do a little more work to get it to fit flush, but I think its the best solution.

Maybe Chris or someone at HPF can take a pic and post it here for the guys.

Just to be clear..... The schematics we sent out for the DIY switch will require you to purge your methanol quite often. This is because those wiring specs didn't also deactivate the methanol fogger closing it when methanol is not in use. You will need to get this pre-wired switch from us that does everything if you want to have full control of methanol without having to purge it.

Take care,
Chris.
