Iv just got a new inlet manifold for my projects engine build and it has the 5th injector port, im thinking as im going to be running a syvecs ecu i can quite easily utilise this, but how, should i use a 5th fuel injector, use it as a mount for a single n20 jet or as a position for a water/meth jet.
What would be my best bet?.
Ill rig up the system myself what ever way i go but just unsure on what would be my best option.

Opinions are very welcome

Difficult to answer that without knowing what sort of project you're putting together. In general though it wouldn't be a huge amount of use for fuel given that, if you needed the extra flow, you'd be better off replacing the four main ones.

 

hello mate.
Im going for a built 2.0, worked v3 heads probably an sc50 billet turbo. I have a set of 850's so as you say the extra injector is probably pointless, I want to be able to run a fair amount of boost on race fuel so was thinking of using a water/meth injection set up to help keep charge temp's down, could i also do this with n2o?.
Im still learning the whole science behind all this mate so forgive my lack of knowledge.
I want to use the car as a road car, but, also want to be able to remove most of the interior, ie rear seats carpet etc (already stripped sound deadening etc) and use the car on the handeling circuits at sso and possibly totb.

 

Also to add i want to use the car on track and possibly time attack in the future.

 

I would go with water/meth for safety especially on a track car

 

would that work ok if was using a meth fuel mix?.

Cheers mate

Spoke to Pat and Simon regarding this and advised it would be fine

 

Thank fella, i think water/meth is the way ill go.
I want to make up the system myself as working on a tight budget so was wondering if it would be possible to use an oe injector to spray the water/meth mix into the inlet, any thought on this?.

Cheers again mate

Ok came up with this idea while bored at work.

I make an alloy tank to sit in the boot, fit an oe sti fuel pump, with mounting +plate etc to the tank, run a feed pipe + return pipe to an oe fuel rail, cut down to accommodate a single 380cc injector mounted into the 5th injector inlet on the inlet mani.
I could use the depth gauge on the oe pump setup to monitor fluid levels in the same way as the fuel gauge would.
Wire the single injector into the syvecs and get my mapper to set it to come in at pre-set boost pressure levels, or how-ever he advised best?.
I have most of the above bits laying around, plus i can do all the wiring & fab work myself so it could turn out to be a budget way of getting a decent water/meth setup.

How does the above sound? would it work?, if there anyone can foresee any prob`s let me know.
