Compare spelling accuracy, and then compare grammar.

You would be unwise to completely disregard the answers that some very knowledgeable members are giving you.

"Like the topic say! Anyone running a mec feul system?Lay out,pics,do and donts .How well system works etc.Any input please!"

The system works terribly and is unreliable. That's why nobody runs it and doesn't know anything (except for maybe one person).

"it will be cheaper to buy a complete mec system than buying a stand alone system in my country.Mec system=+-180 us to a Stand alone=+-1400us dollar.Seen a 13bt drag ldv with set up .Best run was a 10.8 sec=1/4 mile.But car is not driveable on daily basis!Anyone with such a setup?
thanks for input!"

You sure it's only going to cost $180 to fully convert the system to mechanical fuel injection? A megasquirt standalone costs only $200 and you get to keep the inifinitely superior EFI system. And this car will be a fine daily driver. Going that route would be the wiser decision.

edit: Of course, it is completely within your right to disregard whatever advice I or anyone else gives you, but I highly doubt you will be able to find the info you want for the reasons I gave above and also because of your petulant attitude.

Ah I see, I missed that part right before you mentioning the 10.8 1/4 mile.

(1)Input yes from some members(but just remarks ect. from the new club)
(2)Make sense?-first ask then do if,if,if possible
(3)Maybe we all must go back to school again (test people test)
(4)Glad to hear your the president and not the founder!!!!!!!

gingenhagem

Nothing wrong with my attitude.I got answers on the topic+thread(person that did it)+a pm with very good info and people to ask about system(system had been done many moons ago,but is not street driveable)

HMMMM......are we going to continue or is this the END

UP TO THE CLUB

YOURS FAITHFULLY

1) this isn't a selective forum, you're open to whatever anybody wants to say
2) Making sense is relative, to me using outdated technology because you're misinformed about the new technology doesn't make sense.
3) It'd be a start.
4) Yeah, ignorance has been around a long time.

DIETER SCHELLE 07-24-05 05:23 AM

SonicRaT i now see why some are so stressed,they do not know when to stop,or they stop and the next pal continue.(brothers in arms)
THINK ITS TIME FOR PROMOTOIN

NZConvertible 07-24-05 06:25 AM

Dieter, you seem to be the only stressed person here. All your yelling (capitals) is giving me an e-headache. Calm down and listen to the advice you've been given, even if it's not what you wanted to hear. Mechanical FI is not worth the grief when EFI is so readily and cheaply available. You haven't yet given us a good reason not to use EFI.

Gonzales jr. and sr. run mech fuel injection. And they still run with the best of them. I would personally have no idea how to tune such a system. Basically the fuel system has a "distributor" that has a trigger device to tell it when to push fuel to certain injectors. Although, if you can make it work, it doesnt have too many advantages over EFI (not enough in my opinion) but i do belive they run quite a bit more fuel pressure. And if you can get a good price on it where you live, it would be pretty cool to see it done. No its not at all like a carburetor, (dont put a toilet on your intake). Because it provides much more equal fuel delivery in a sequential manner.

.

This is quite a generalization. I know that gonzales jr. and sr. have been running them for a while. However, i know they have also had problems when going into different elevations, because there is no ems to compensate for atmospheric pressure.

You know what, go fuck yourself.
If I was "rolling in dollars", I would have a MoTeC M800 fully-unlocked with a MoTeC ADL back-lit with it.
I just hate idiots like you who have false impressions on who I am.
You haven't even met me, and yet you think you got me all figured out.

I'm not "rolling in dollars" like you wrongly think.
I work hard for my money.
I work two full time jobs so that I can work on my car and modify it to my wants and needs.

I'm try not to getto rig shit like your sorry ass, so I work longer to and save my money to buy things properly.

Speed takes money.
It's a concept you don't seem to understand yet.
Maybe that's the problem - not the mechanical fuel injection - it's just you're a lazy bastard.

Good luck getto rigging your shit, cause it's either going to blow up on you or kill you...

RandomHero 07-24-05 03:59 PM

damn, hey dieter, this whole mech. fi thing is interesting to me. Yes, some people are simply shut down to the idea, but thats cuz in the end, all things considered, an EFI system is much more efficient. But theres no need to make enemies of them and talk all kinds of trash, who knows these people may be there when you need them.

SureShot 07-26-05 08:09 AM

So you want to see what mechanical FI on a 13B can do?

I think there were maybe 14 alcohol injectors after the monster turbo in this intake.
They were controlled by a progressive mechanical valve linkage.

It was all custom engineering and was nowhere near streetable.

locketine 07-27-05 01:21 AM

If you're willing to spend all the time fixing a mechanical system to work on your car, you would be better off buying a megasquirt for the $300 us they sell for. Sure it's slightly more than what you claim is the street value of a mechanical system, but it's better and easier to deal with once up and running. Atleast I would assume since the whole point of efi is that it can be changed via electronic input, something that a straight mechanical system simply can't compete with.

As for you people yelling at this guy. Don't do it, it's only pissing him off and you off as well. He may be ignorant of the virtues of efi and how shitty mechanical injection is, but let him know with constructive criticism. It pisses me off to no end when people put carbs on our cars but all I do is tell them that there's a damned good reason carbs were phased out in the 80's. There's also a good reason mechanical fuel injection never even became a mainstream system.

http://www.ronsfuel.com/ This is what Carlos Gonzales uses. It is a Rons Mechanical fuel injection system modified for a rotary. He is making upwards of 900rwhp and pushing well past 35+psi boost. If you call Rons Fuel Injection Systems they can give you Carlos Gonzales number he is in Florida. Or do a search for GNS Racing. This is a quote from one of his post "Hi this is Carlos if you are really interested on finding out how the mechanical fuel injection system works call me at my shop. The number is (352)-237-7955 and fax (352)237-5327. Thank you."

DIETER SCHELLE 07-27-05 01:36 PM

Thank you for all your info etc.(SureShot,locketine and 13btnos)

SGPguy-Thank you ,dont want to make enemies but if some one start giving me shit i will give him shit back.(shit remarks=shit remarks)was just asking thats all.Then answer,but did not even try to explain why or what!Think he could not give info ,why did he just shut up and kept it to him self?That answer he gave me is not surely input or may be i can not read?Thats all!

NZConvertible-Question is about mfi and not efi!Ihave seen rotaries running with efi systems.I am interested in how or if it could work-mfi!
And if i give you a headache stop reading, i am not forcing you to read or take a pill

RETed-Cowboys dont cry!!!!Dont get pissed off,i asked a question and you gave a shit answer.To me thats not a answer why did you just kept it to your self?And to your
Go fuck your self answer ,well bud,THE FEELING IS MUTUAL!!!!!!!!!!!!
And sorry to hear of your two jobs,maybe you suck at one,maybe- maybe not

TO ALL THAT GAVE ME INPUT ,WEB SITES ETC. THANK YOU !!!!!!!

PS:Good luck to the new club with its members!!!!!

Arvika 07-27-05 04:10 PM

Look at this video... (right clic and save as... it's 35Mb big) This is a Swedish 300hp PP ported N/A RX7 with mechanical Kügelfischer injection from an old Peugeot, racing against 700hp Corvettes and other big engine racecars!

Funny thing, Bosch got the rights to the system for very little.

What? You thought Bosch invented fuel injection?

Bosch bought the system from Rochester, who had been making it for Chevrolets since 1957. They tinkered here and there but it's the same system in a nutshell.

That is for airflow-metered FI. There have been several different flavors of TPS-RPM fuel injection (Hilborn, Enderle, etc), and I know they've been applied to rotaries before. TPS-RPM systems are generally race only, since they have a "flat" fuel curve, meaning you adjust the mixture for your powerband and it runs too rich elsewhere (your powerband is where VE is highest so you won't run lean anywhere). And minor annoyances like the fuel lines bleeding down into the engine after shutoff, causing a guaranteed flood-start, things like that.

I've got that setup sitting on the floor of my garage. Gotta love those old chevy's!

Ted, remember that cowboys don't cry ;).

DIETER SCHELLE 07-28-05 12:23 PM

NOW that is info.!!!!!!!!!!
So it can be done but you can not drive your car on the streets(feul,air mix does not stay the same all the time)
Thanks for info


RETed
maybe-maybe not????
Maybe you the only employee there?
(OK, will stop now!)

This is my Rx7 Runs mechanical injection i have a few cars that are on Hilborn injection. I’ve yet to see an EFI system that can match the throttle response mechanical injection. I feel the air bleed injectors on the mechanical systems are far better at atomizing the fuel. But to each his own so they say.

How much did all of that cost just to make about 200hp?
