twin fuel rail 7mgte

[24vtoy]

hi guys

has this ever been attempted

Twin feed fuel rail for the 7mgte

ive got 2 sets of 440cc injectors so im trying to figure out how i can use them :icon_razz

 

[bioskyline]

i have seen it done, but will require a custom intake manifold. a set of 880cc injectors would probably be cheaper though

 

[IJ.]

Not to mention if you lose 1 injector you have enough fuel to torch the top clean off a piston...

 

[Devin LeBlanc]

sell both sets for 60 a piece and put it towards a set of 850CC injectors

 

[24vtoy]

hey bioskyline where have u seen it ? id like to see what it looks like

 

[Devin LeBlanc]

I think you would burn up the stock ECU injector outputs anyways running dual coils of each of them. Unless you are stand alone and have an ability to run 8 injector circuits I wouldn't recommend doing it

 

[hvyman]

If your needing that much fuel should already have a standalone.

I wouldn't pay more than 40$ a set either.

 

[24vtoy]

yeah stand alone system

$40 a set for 440's hvyman ?

 

[hvyman]

ThAts what I would pay. If they were cleaned and flow tested 60-70.

But there 19-25 year old stock injectors so...

Also you can domestic 80/lb injectors from pre for like 360$. Much cheaper safer way of going about things.

i cant remember, but 6 were on top, and the other 6 were mounted underneith the manifold. ill look

You could use either Mosfets, Solid State relays or even Ign igniters to run the 2nd bath but the fact still remains if you lose an injector you have built a blowtorch....

There's a reason AIC's went the way of the Dodo, these days large injectors are cheap and reliable so there's no reason to run duals.

 

[Devin LeBlanc]

Yeah that could be done, Just half the people would not go through the trouble of doing so, they would probably just parallel off the harness and end up frying something.

Hvyman, Ill be using 780CC injectors on a stock ECU.

 

[hvyman]

Never said you couldn't. Your also using e85 which needs a lot more fuel for the same hp.

If I was you I would be investing into some kind of standalone to make better use if the fuel. Stock ecu is the limiting factor in your setup.

 

[Devin LeBlanc]

Thats where I have some advantages Wait untill its done

My Dodo Device is in the shed waiting for incorporation into my build... someday... maybe...


...and yes, I am old, not extinct, but working on it SLOWLY... and perhaps a bit "odd" so it's all okay.:biglaugh:


(Someone has to carry the torch for the yesteryear yahoo's among us!)

We use a dual fuel rail and dual set of injectors on the Malta dragster as a staged set up. 861 cc on the primary rail and 1200c on the secondary rail. Not really needed for a street car.

Fuel volume in EXCESS of many engine displacements! THAT's a LOT of fuel, Rich!:aigo:

wow...holy fuel..

 

[suprarich]

Need a bunch with 1400 rwhp and 10,000 rpm

oddly enough it is for sale here on the fourms.... http://www.supramania.com/forums/sh...e-ported-head-gm-trans-adaptor-etc..-for-sale.
