Thread: Methanol install

Has anyone ever installed the tank and pump in the trunk of the car? And fed the line up to the engine bay? There is absolutely no room for the tank and pump in the bay so I'm brainstorming other ideas. Any suggestions?

im sure it has, have you tried looking in the front bumper? i got my ic res tank mounted up there.

GPs don't have any space to speak of there either. The biggest empty void nearby is ahead of the driver's front wheel, behind the bumper. Where the filter on a CAI setup sits, or near there.

if you take that plastic cover off i bet you find space in the front. my car came with some rubber flap crap over that area, it was removed 5 years ago.

you need to be able to refill his meth tank too, so lower side of the bumper wont cut it.

and most meth tanks are kinda small looking to me. smaller then the tank i got i think. mines like 6 tall 6 wide, 4 deep.

Maybe the right tank shape would fit up there then. GPs do have some extra ductwork in the way behind the tiny grilles. If he has a CAI already, theres some room over by the tower. Surely this has come up in previous threads and been neatly solved. In the hot rod shop, you start with a sheet of aluminum and just make it to fit the available space lol. A creative person might also look to the cowl area.

ive seen tanks on the firewall too. pass side may have room.

You can also move your battery to the trunk and free up that space to mount a tank

I have a cone intake but I put the PCM tray there so there is a bit of room but a tried to put it in and there isn't enough room. I thought of the firewall but it's a bit out of the way to fill. Is the trunk not a good idea? I was gonna put pump and tank in the trunk, run a line under the car and come up with fuel lines for the nozzle

I would consider that but I cannot get the pump to fit anywhere on the front side of the engine bay lol

Did you drill a hole in truck to run the tubing?

Also what nozzle do I use? I have 2 in the box, a 375ml/min and a 625ml/min. It says the 375ml nozzle is for 350whp but you can lower injection amount my lowering pump pressure. What's my ideal setup you think?

How do you wish to use the meth?

Do you want to use to combat the knock or as an extra fuel source??

That will kind of determine how far you can take it. Say you were running 93 pump gas and a 3.2 pulley and you were running out of injector, you could use the meth to basically add fuel and cool the temps down. Then you might get away with another 1-2º of timing. Figure on any small pulley if you can get away with 14-16º of timing you are doing pretty good, some cars may only like 12-13º. This was a bad crude example but sort of how it works.

I don't see the need for meth injections unless you plan to run down around a 3.0-3.2 pulley range because that point the supercharger is creating a ton of heat compressing that air and regular pump gas burns pretty hot and could create alot of knock.
