Dual nozzle with an old smc non progressive kit?

Now before everyone tells me to change to a new progressive kit, I really don't want to for now because I have this kit since 2002 and has never given me one problem and has always run well. This is the old SMC kit with the round bottle and the pump on the inside. I run it on 95 % ethanol and I know if I would switch to a new kit that I could use methanol I would probably make some more power but I am satisfied with the results of ethanol for now.
What do you guys think about this? I want to get a dual fitting, and another braided line with a jet from smc and turn it into a dual nozzle kit. The reason I want to do this is because on my old set-up that I had my pump speed was maxed out, so I figured by doing this I wont have to run the pump at max speed and will have some room to play with it. Would like to know some opions about this and if there is anyone that has already tried this
with an old SMC kit

This is going to be my new set-up: T-Top 86 Grand Nationals 109 block with weisco forged pistons and 2 billet center main caps, M&A aluminum heads, roller rockers, port match lower intake ,te63 a.r .82, 214/214 cam, smc alky injection (95 % etanol), 25.5lbs boost, 94 octane, hooker cat back with dyno max ultra flow muffers, 60 lbs injectors, extender alky chip with 23/21 timing, with a gen 2 with a LS1 maf,thdp, mease 24 row IC, PTC 3200 stall 9 1/2 convertor, Ron Custom max boost brake module, MT drag radials (275/60/15) , rjc power plate, rjc boost controller, zeitronix wideband, HR motor mounts, Weld Drag Lites with skinnies up front, electric exhaust, hr rear sway bar, no front sway bar, 90/10 lakewood in the front and 50/50 lakewood shocks in the rear with energy suspension poly bushings all over, boxed rear lower control arms, Big mouth cold air with an AFE air filter.

I want to run in the mid tens and hopefully one day in the low tens.

Thanks alot for your opions, it will be greatly apreciated.
Marco.

It's easy to add the second nozzle as you mentioned.

If you want to stage them all you need is a Hobbs adjustable switch from NAPA, set it at 18-20 psi. and a solenoid from a Parker dealer or NOS alky. solenoid which is much more expensive, ss. version 1/8" NPT hose taps in it.

About $75 total and you won't notice a bump in the A/F while boosting up. :smile:

With that new setup however you may need/want more flow than just 2 with an EFI type pump.

You might want to consider Steve's newer progressive kit with larger pump, I'd surely ask him first. :cool:

evil666,you have a nice buildup there,do you really want to trust all those $$ to a 7 year old alky pump that is already maxed out?inmo you should at least upgrade the pump and run another nozzle.i like progressive alky personally but that is your choice, good luck

I did the exact same thing with my old SMC. Used a M10/M15 combo, and it definately flowed more alcohol than it did before. That being said, you will run out of room with it. My pump was cranked all the time, still couldn't get enough out of it.
Bought a new progressive kit from Razor, couldn't be happier. Now THAT flows some methanol! :eek:

Grumpy next time make that cell phone call before you post. :p

Controller may be on 10 for his setup but when you add nozzles you still get much more flow and slightly less overall pressure.

Basically the pumps are operating into a very small .050" hole in a nozzle instead of a fuel rail of 3/8" dia.

That's what builds up the pressure, it only drops slightly when you double the hole from .050" to twice that size, still nowhere near the 3/8" hose they normally operate into.

Try 3 nozzles with that system for alum. heads. :smile:

You can also hotwire the SMC EFI pump right off the battery and use the SMC pump output voltage as a trigger to the relay, that would get you max. battery volts to the pump with little loss over the short wires to it.

After that get the SMC progressive pump if you need more flow. :cool:

It ain't rocket science. ;)

hey salvage did ya read the post ??? we are talkin a mid to low 10 sec car.. not a high 11 12 sec car :rolleyes: I know I know .. your DIY alky system can do that with your eyes closed... right??!!:p

He's running the kit now and wants more flow, that's what I got from his first post and yeah I read it. :eek:

There's lots more to be had before going to a larger pump simply by adding nozzles.

He might make his goal of mid 10's that way. :smile:

Staging them is a very good way to make a non-progressive kit progressive. :cool:

If not he can move up in pump size, like many have suggested, after he maxes his system out.

Like I said it ain't rocket science. :rolleyes:

I also assumed he knows how to tune his own car, I guess that's a big assumption for some people using alky. :p

And the DIY system did it 8 years ago maybe 9 or 10. :p

I was talking about the SMC system in this thread however, maybe we should stay on topic. ;)

Your first post didn't add much since pump speed maxxed out certainly doesn't mean the flow is with that system.

Ok.

Your first post not only was a complete assumption, it was an incorrect one. :rolleyes:

At least I included some facts. :p

You can greatly increase the flow of the SMC kit with multiple staged nozzles which was direct to the point and in response to his question. :)

Reaching goals is for the track not the internet.

I think that is in some mis-informed gooroos signature, or maybe his alky. gooroos signature, or his tuners signature, or his engine builders signature, or his drivers signature..... :biggrin:

Nope not my engine, or my headgaskets, mine are still the GM stockers. :cool:

Others tune with them, I read that in the alky. section here long ago. :p

Hey someone's gotta push that envelope... :eek: :rolleyes:

Thanks everyone for your help and advice. I emailed Steve at SMC about the topic but still didn't get back to me yet. I still think I will add some nozzles to the kit and see how far it can bring me. I know low tens are out of the picture for now until I upgrade turbo and alky kit, and a lot of tunning. I will try for mid tens and keep a big eye on wb #, KR and see if I could bring the boost up a little at a time and play it safe.

Thanks,
Marco.

well be careful and watch for knock !! a low 10 sec car things happen FAST :eek: :biggrin:

Salvage.. ya you have stock head gaskets because ya don't race the car.:rolleyes: then when ya did ya ran high 11s with a 70 turbo?? :eek: and your giving advise on a LOW 10 sec car ?? :confused: :p

6 passes on the GN to the 11's with a PTE51 and the SMC kit.

Try some facts for a change Grumpy. ;)

And you the obvious "expert" on the SMC stuff when you couldn't break mid 12's with one. :eek: :biggrin:

Your words on the internet, remember? :rolleyes: :p

I gave advice that was actually totally true, not being negative like you about a subject you have no clue about, more nozzles with an SMC kit. :p

Staging the nozzles will more than double the flow with that kit, he knows how to tune his car, no cell phones necessary, if he can get 120mph out of a single nozzle, maybe he can get a "bit" more with more than DOUBLE the flow.

I never mentioned how to tune, or race, or what boost he's gonna run with his low 10 second car.

But I sure know how to more than double the flow from a single nozzle. :biggrin:

Best of luck with your car and goals Evil. :smile:

ahhh the net :cool: so 6 passes in the last 20 years?? I have NEVER used an SMC kit (I use those big $$$$ kits:p ) on any of "MY" cars BUT I knew people that did. Melissa's GN was one of them. Oh I ended up with thier cars and did the "Dan" thing.. Pieced out what I didn't like:eek: sooooo "Dont tell me what you can do Show me what you can do" :p
