SMC Kits.... no 3 bar MAP?

[BlackMetal]

I'm trying to compare the SMC kit to AlkyControl. I'm wondering why the AlkyControl kit includes a 3 Bar Sensor while the SMC doesn't, yet they both claim to be able to do the same thing.

I know everyone will say "just go with Razor and stop the guess work", but frankly I'm freakin poor right now, $530 would be a lot for me to spend.

You have "coming soon" new wheels, maf, etc... Spend that $$$ elsewhere.

Put the money on Razor's kit and dont think twice. It is built right, has the R&D behind it, and the best customer service to boot. If your poor you picked the wrong hot rod to own. Wait a minute...all hot rods make you poor

the SMC controller is boost sensative.. there is a vaccum/boost hose that comes from your engine to the controller

Ah, ok. Well in that case it seems like the SMC is nearly the same for $130 less. But everyone says Razor's is worth it, so I guess I have some deciding to do.

Razors! I have one on my TTA and bought another from him today for my GN. Like everyone else says. DAMN WORTH IT!!! EVERY PENNY!!

 

[BlackMetal]

Well unless someone can point to specific improvements over an SMC kit, I'd be inclined to save $130.

As far as all the other stuff I'm spending money on: I bought the 009s used, only because my stock injectors seem to be leaking a bit on the passenger side. The wheels I'm buying are cheap 15" wheels so I can get rid of my expensive 18s and hopefully make some money back. The MAF I'm only upgrading it because I think my stock one is on it's way to failure and OEM MAFs are expensive. Only doing the 3" exhaust system if I can sell the exhaust that I have now. So like I said, I'm poor.

Size matters . Just look at the pump size difference between the two.


Razor also has an "alkyway" plan set up. Just shoot him a few bucks when you can afford to. He'll put it towards the kit.

Well that's more like it, someone who actually gives me a reason besides just shouting RAZOR at me haha. I was unaware that there was any difference in the pumps.

The SMC says it's a 110PSI pump...what comes with the alky control kit?

 

[Roc87]

It's a shurflo pump. Not sure what it's rated, but I have a pressure gauge (also from Razor) that shows it's past 200.

Smc

My car came with a SMC kit, and when I upgraded Steve gave me a great deal on a new progressive kit. At the time I never heard of Razors kit. I am very happy with SMC. Steve makes a quality part. Of course Razors kit is widely used on this site, and I'm sure part of it is due to him being a supporting vendor. But the ability to share the knowledge he has on the site may just be worth the few extra dollars.
However, the SMC IS a quality piece, with MANY users out there. I have yet to read or see anyone post that their motor let go due to SMC kit.

Hope that Helps,

i have personally tried serveral kits
Razzors
SMC
Devils Own

all on my car at the dyno and they all made within 5-8 HP .
they all supressed knock etc..they all got the jod done.

it really comes down to preference,price, and customer serive.

I have had great dealings with all 3 vendors.

I have not tried any kit but Razors and I will say that upfront.

I would be kind of weary of using a pump from SMC mainly because it looks so small. I do not have any facts to back this up, but from pure looks, Razors pump wins. He also has made internal mods to it and really all it is, is a shurflo casing. Razors kit has many fail safe features, ie. pressure sensing led (red to green), low level, in dash low level, comes with a power injection bulb, a test button, and it is fully adjustable.

I have found that with my TTA, the kit works best coming on at 4 PSI and alky knob on just a hair below 5.

Razors alky kit+Erics chip=no knock hard running reliable car...

 

[Black Power]

SMC kit is wonderful, I am sure Razor's is just as great. My SMC was easy to install and fantastic results.

 

[BlackMetal]

Thanks for the replies everyone, glad that some SMC users spoke up. I guess I just have some deciding to do.

 

[XxDarkSidexX]

smc progressive just went low 10's again here on the west coast, many around the nation have been 9's with it
SMC is also proven alky and works hands down!
Easier to install and has duel nozzle progressive incar controller too.
They really are both good kits.

but i got a razors size does matter, at least thats wat the ladies say . if SMC small works hands down then bigger
hands down dominates. I feel safer dominating haha, my GN1r's also feel safer.

I went with SMC's progressive kit on my GN. Haven't been back to the track but I am running 24 psi with a Lubrant race chip(26 deg), no knock in third(a tickle in 1st ~ 1.0-1.7). Can probably lose that with a lower turn on point. I've been happy but razors larger,more reliable pump is very tempting:biggrin:

not trying to hijack this thread but im in the same boat you are i was really looking hard to find a reason not to buy the SMC kit...im kinda poor lol so the way i always understood.. the 3 bar map is rated up to something like 40 lbs of boost? the map sensor we have is only for 30 lbs? i dont plan on running anymore than 26 lbs with alky depending on knock why would i even need a 3 bar map? i guess i dont understand how one kit it is necessary but on another it is not...not trying to bash n e ones product just trying to make a good decision on what kit to buy also :smile:

 

[DavzGN]

Actually a 3bar map only goes up to about 30psi. Less than 1 bar is a vacuum reading.
1 bar is about 14.7psi (no boost)
2 bar is about 29.4psi (14.7psi boost)
3 bar is about 44.1psi (29.4psi boost)

A 3 bar, or any other, for that matter, has to have the atmos psi subtracted from it's coverage range.
3 bar has to cover atmos, thus it's fairly accurate to an added 2 bars of boost.
Same goes for a 2 bar, or even a 1 bar.....

At 26# boost, that's just short of 2 bars. Add the atmos psi in, and the 3 bar is getting close to the top of it's range...

My car came with Steve's (SMC) old kit, and when I sold the kit, the new owner complained that it had a leak....Steve sent him a new reapir part at no charge. Car ran great, except for the bog when the alky came on (non-progressive kit)

I now have Razor's kit, and have had no issues with it. I purchased based on the ongoing R&D that Julio does, the simplicity of the installation, and the proven performance.

Would I go SMC again? Sure.

Before you fret over the $130 difference, you'll want to research out a bit more. If you add the variable pump speed controller to the SMC kit ($100), it's only a $30 difference you're looking at; Alkycontrol has that control feature built in.
SMC Alcohol Injection

If you add that feature, you're looking to tap into the MAF signal; Alkycontrol does it via the MAP sensor.
