Newbie Forum - Beginner/newbie/general DSM modification questions. First mods, how to run 10's when you haven't run 12's yet, any tech question that doesn't fit in another tech forum.
www.alkycontrol.com his shop is right near me, and i would say it is the best out of any companys using the sureflow pump. it has a progressive controller, meaning it comes on at whatever boost setting you choose, then as boost rises, voltage to the pump also rises, causing more methanol to spray at higher boost, so you wont get a sudden dumping of methanol. it also has a pressure sensor built into the pump that will turn an led mounted in the car green when there is line pressure, and will turn red if there isnt. i have been using this kit, and its very good.
That's the kit I installed in the Spyder a couple weeks ago. Nice kit, but don't bother upgrading to an angled nozzle. It doesn't look anything like the one on their website. The thing is freakin' huge. I didn't even bother to install it, since it looked like it was going to eat up about 1/2 the area in my UICP. Waste of $14.
How often do you have to refill it? For a daily driver do you need to continuously fill it? I mean I know it has to be refilled but how frequently for daily driving? It comes on at a certain psi level right? So if you drive it normally for the most part but really get on it a few times a day when driving is it going to use up all the methanol really quickly?
Correct if you stay out of boost, you save meth. I have heard 1 gallon lasts about 1 tank of gas. But it really all depends on so many factors.
There are probably cheaper deals out there. Heres what a quick googal has provided:
ShurFlo Pump (adjustable peak flow pressure via allen screw)
Hobbs switch (controls activation via boost: Its adjustable!!!!!!!)
McMaster and Carr nozzles, Catalog page 1898 - 1901
#'s GPH@40psi GPH@100psi
3178K81 0.63 1.0
3178K82 1.26 2.0
3178K83 1.90 3.0
3178K84 2.53 4.0
3178K85 3.16 5.0
3178K86 6.32 10.0
3178K87 9.49 15.0
(nickle plated nozzles are best)
A few screwclamps and possibly a tank if you don't tap your existing windshield wiper reservoir
The key is activation point and choosing the proper nozzle flow. Activate the hobbs switch at a boost level that will allow the pump to flow enough injection yet will not bog the engine. This takes time to get down.
This homebrew system has gone thru 3 cars and 10-35 psi of boost for 6 years. Water injection, water/alky mix, pure meth injection.
$160 total including shipping. Add the cost of hose, clamps and fittings. You're still probably under $180. And the setup works for years. . .
For the longest time I didn't even run a solenoid valve, I just ran a check valve. It did good. But got clogged over time running meth (ate away at the rubber hose). A good fuel filter (that can handle the psi) just before the check valve really helped this. So you can subtract the cost of a $35 solenoid. the check valve I got was around 10 bones.
It allowd me to run 22 psi w/ stock 450s on a small 16G and stock intercooker(not a typo), stock fuel pump stock everything!!!) and I ran good and lean w/ lots of power on a hacked maf. . .
It says this is made for 100% meth so there is no mixing with water? If this is a dumb question then I apologize. I am just learning about meth injection.
