In the summer I still use methanol on top of my non-meth maps. Devils own and Boost Juice are good, but I am now mixing my own 50/50 mix VP M1 with distilled water. So much more cost effective!

Do you know how much it takes your torque up with the meth tune?

I'd have to take a look at my dyno sheet, but I want to say I didn't gain any torque from the meth.

It's not apples to apples, but I gained a ton of torque when I added meth on my last car. 40+ lb/ft. I didn't pick up any hp, but that turbo was pretty tiny. I could run an extra 4 pounds of boost on meth over straight 93.

If thats the case I guess I'm getting a new map!

It all depends on the tuner. If you just want to run it for cylinder cooling and IATs, you probably won't gain any torque. If you have the tuner add a bunch of timing since the octane will now support it, you'll pick up some power.

You can also run a leaner AFR with water injection since you can replace some of the unspent fuel that is used for cooling with water, which has a much better specific heat.

Snow Performance Boost Juice

I am assuming it is 1 gallon at $8.99? The product description doesn't even say how much you get.haha

If your just using it for its cooling effect and not bumping the timing for the hp advantage

It's like getting a nos kit and instead of going for the simple jet dry shot your getting the full 2stage fogger wet kit but then only doing a 50shot

Just my 2cents any way I will post a picture of my setup on my old Stillen kit

It was a nice clean look. And worked well.

That looks clean. What stage kit? The price range is big from stage 1 to 4. How much juice do you go through on average when it was on?

How much did it cost you to make a gallon? The boost juice linked above is $8.99 per gallon (it seems).

VP Racing fuels also sell meth in large 5 gallon drums for $40-50 IIRC. They have physical locations you can go purchase these drums. ^^

I'm planning on using around a 50/50 mixture just to be used for IATs. After doing some math from some Subaru forums and the Aquamist forum, I should go with a .7mm nozzle for the IC and a .9mm nozzle for the TP, does that sound about right? I'm not looking to run crazy boost or tune for it, just want some protection from summer heat.

I'll be running a GTM Basic fuel system with Denso 600cc Injectors and Walbro 255 Fuel Pump. I'm inly hoping for around ~500 whp with low boost.

With VP's M1 costing me $45 for a 5 gallon jug and distilled water being very cheap, I can make 10 gallons of a 50/50 mix for less than $50 vs $35-40 for 4 gallons of Boost Juice. When JEGS has free shipping on Boost Juice that is only way I could justify buying it. Shipping can easily add $10-15 to 4 heavy gallons being shipped.

How long with 1 gallon of juice last you?

A gallon will last me anywhere from 1 1/2- 2 months.

I should have asked clarified but how many driven miles is that? With the occasional boosted run.

Nissan370 01-31-2014 02:51 PM

I was using boost juice and I still have 5 gallons left
Driving like I have cents and just boosting it every now and then last me a month or so
Drag strip and boosting a lot maybe 2.5-3 weeks

Also I had mine set to only spray over 6psi I was making 9-10 psi max
With the Stillen kit

I drive my car about 10,000 miles per year. I don't track it, but get into boost at least 3 times a day. My methanol is set to come on at 3500K.
