Advice needed for SMC ALKY Injection Install,previous users?

Code what?
I will be getting the complete SMC Alky Injection kit next week and was wondering if any body could shoot me some idea's or tips for intalling this system. I plan on mounting the spray nozzle under the IC infront of the trottle body so it hidden from above. Any suggestions or comments about the kit would be greatly appreciated.

Thanks
Erik

just my opinion but why bother hiding it so much if on your dash you have the huge control box that is easy to see

Don't hold your breath- mine took nearly 4 weeks to get here. Also, do what I did and connect the clear vacuum line to a regular vac. line before running into the engine compartment- the supplied clear hose get dangerously soft with our underhood temperatures, but it's glued at the control box so I got a vacuum line fitting and used rubber line under the hood.Put a drop of super glue on it as well- they have a tendency to pop off under boost. That and hold on. Oh- get some Uplon alc./methanol lube from Klotz. www.klotz.com put 1/2oz in the bottle with each fillup- the pump needs some lube.

I put my controller under the front dash tray so I didn't have to drill to many holes in the dash. Find a better way to mount it than the supplied velcro- it gets hot when parked and the glue goes soft.

It's SY/TY specific but that only means it has a 4' hose instead of the shorter one for the GN guys.
OBI- you need pics? I'm sure Weelr wants some to. Until my batt. relocate kit gets here I can only have the bottle in the truck w/ the air cleaner removed, so it's currently a track only deal, but the kit should be here in a day or two. Next track date is the 19th but if I put it in before I'll send you both some pics.

Mine is coming in next week, as of today i found out that the kit that was orderd for me was ment for a GN. Conley's here in Houston ordered it for me and gave me a realy good deal for $300. If the only differance between the GN kit and the Syclone/Typhoon kit is the longer hose i think i can deal with it, i'll just get some longer hose. Anyone have anymore info on this?

Thanks for the input guy's

I just ordered my kit directly from SMC for $354 shipped to my door. I'm sooooooooooo anxious to see how much it helps reduce KR with 91 octane! :D Steve said my kit was Sy/Ty specific and comes with the braided lines.

If your truck develops a fluctuating tach after the install with the pump running, a cheap modification will be in order. Go to Radio Shack and get a 220uF eletrolytic capacitor part number 272-1017 for about a buck. This type of capacitor is polarized meaning that it has a positive side and a negative one (most caps aren't). If you look on the side of the cap, there is a arrow showing which end is positive and which is negative. The "point" of the arrow is the negative side. You will need to attach the negative side of the cap to a good ground and the positve side to the power line on the controller. I soldered a wire lead on both sides of the cap when I installed it on my buddy's syclone. After this is done, your tach won't jump around with your alky pump running. Don't worry about the validity of this modification because that's what SMC told my buddy to do to fix his problem. HTH

hey you get what you pay for. the smc kit has special safety features that warn you when you are low, you can adjust the pressure with ease and a really nice dash mounted unit. if you want a cheaper kit go to autozone and but the parts and mimic their construction. just remember, most often. you get what you pay for. :wink:

Does the SMC Alky kit deliver increased flow proportional to boost or does it just come on at a certain level? Aquamist delivers proportional to boost level. Has anyone tried aquamist?

SMC kit really isn't expensive considering what you get

Parts included:
pump (EFI type, pretty tolerant of non-gasoline liquids) est $100-150
bottle (hd plastic) est $20-40
wiring etc
pressure switch $15-40
pump speed controller (pulsewidth modulated) $20-50
low alky sensor est $10-20
braided lines $20-30
jets/nozzles/checkvalves $20-50
enclosure/knobs/lights/sticker $20-40

Prices are just my estimates.. but you can see it adds up pretty quickly.

Output is not proportional to boost level, but IMO, that isn't a huge necessity unless you are running a LOT of boost (25-30) where the pump comes on at 15-18psi. You'd either need a sequential multi-jet system or a pump controlled proportionally to boost. If you are running 20psi, and you turn the pump on at 15psi... you will only be 'over alky'd' for a couple psi. At that point, your boost level is rising pretty fast, so it's not a big deal.

The Aquamist kits/components are *top-notch* IMO, but their alky amount delivered IS less than what most Buick guys are using to achieve there race gas calibration levels (aka running 20-25psi on a race chip, using 93 octane). Basically you'd need to use 2-3 Aquamist pumps, and 4-5 Aquamist jets to achieve the same output.

What we are doing on a local Syclone will be to run a custom kit, as a few Buick guys have done. A Shurflo pump, using 4 of the largest Aquamist nozzles, fired sequentially.

Also, I have pics up of the SMC kit install on my old Ty.

so bdubb, if my truck is totally stock except for k&n and 160 thermo & hot wired intercooler pump which set up should i use for driveability. the alky or aquamist? im having a pinging issue at normal driving say going up hills at 1500 rpm. we can only get 92 octane out here. :cry: [/code]

DON'T MISTAKE ME FOR BDUBB !

I am BG :eek:

If you are pinging at light throttle with 92 octane, alcohol isn't going to help, as you really want to trigger the alky at 10-15psi of boost. Light acceleration won't even trigger the alky. I'd exhaust other possible causes of knock if you haven't already.

it seems like someone should come up with a way to vary the voltage to the pump based on boost. not that i like them, but doesnt KB make something like this for the fuel pump. mabe it could be used on the SMC pump? just thinking out loud......

Well the one issue people keep overlooking is that varying pump speed varies pump pressure. This does alter the amount delivered, but also at the expense of atomization, which is crucial.

that is why I would use propane, as a gaseous chemical it is colder and has better atomization. but smc kit works, is proven, and is cheap. so i am stumped. for my purposes, smc. for more boost, like t323psi, propane.
