[LT280z]

Hey guys,
So im new to the methanol but not new to cars at all. Since this is my first post i will tell you about my current ride and my project car. The project car is a 36 Ford with a 396, heads, fast efi, TT, etc and is going to be one hell of a car when its all done so im looking to put a meth kit on my Datsun 280Z so i can get the learning curve under my belt before the 36 is finished.

280z: Turbocharged, Megasquirt efi, 7.8:1 compression, currently running 15 psi but after the meth i will crank it up some more (20-24)

Questions: What are the pros and cons of running straight meth on my 280z as far as cooling and fueling are concerned? Does running straight meth require different fittings or lines? any info on this would be appreciated. Also i like the idea of a direct port set up but im not sure D.O. has nozzles small enough for my application. The car will be making around 350-400rwhp with the boost around 20-22.

Any info on the straight meth, direct port pros and cons, etc would be appreciated.

Just ordered my Devils own kit yesterday! Found it on Ebay for a steal and its still new and in the box.

My ems runs off of a 3bar map daddy sensor so im still not sure if i will need an additional sensor or not?

Our kits are designed to 100% methanol all day long. Every car is different, some like a mix some like grand nationals like it strait. It all depends on the vehicle, You can start with 50/50 and work your way up or down from there.

we carry M1 nozzles for are smallest size, but direct port is really not needed on most vehicles especially anything under 700hp hp. Newer engines are computer designed so their intake tacks mix the air very well to get it to the cylinders equally.

If you got a progressive system and the map sensor is of a GM scale the the controller will function just fine with that.

Well i wouldnt consider the L series a "Newer engine" because it's been around for almost 40 years. Its a straight six design and has been known to run a little lean on 2 cylinders. I have seen many Meth kits with single nozzles on the L series motors and they all seem to do fine so maybe thats what i will do in the beginning just to get used to the kit.

On another note: My kit came in today and i need to order a few more parts for it. I already know i need the gmmap, nozzles (7 according to calculator), some line, tank, etc .... If i mount the tank in the trunk would you see any benefit to running a solenoid vs check valve? If there is an advantage to either i would like to go ahead and install the better part for my application. I will post pics of my kit later!

did it come with those hoses?

[LT280z]

Yeah it did, but you have to remember that i bought the kit off of ebay for a steal! I dont know if they came with them or not from Devils own though?

Can you run a 3 bar map with a 2 bar controller, 2 bar map with 2.5 bar controller etc. I dont even know which controller i have..Doesnt say anything on it so i have no clue..It looks older because the newer models seem to have knobs that protrude from the controller. Any info appreciated !

I can't see the photo on my PC its just blank, But if the controllers 3rd LED flashes then you can reset it to work as a 3 or 2 bar. You can use it actually on any map sensor the scale will just be off.

If you use the 2bar older not swithcable controller then your scale would look like this on a 3bar map sensor.

Now that I am at home I can see the photo, That is one of our very first kits, Almost 3 year old, That braided line looks like a extra. I would avoid using it with methanol because it could be steel at the ends not brass and will corrode rather quickly. I would replace with our current hose and just get the pump fitting and nozzle fitting.

That controller is not switchable. I would run a relay inline with that old controller for sure because it is not as beefed up as the new unit.
