StAndrew's Build

I'm still interested in hooking up and trying out a Nos wet shot fuel nozzle (minus the nitrous oxide) to fuel a turbo'd car. That seems WAYYYYY less expensive and way easier than messing with 6 injectors and a controller. Maybe hook up the valve solenoid to a hobbs pressure switch

 

Just 1 injector?

 

Basically yeah. Not really an injector but a nozzle made for fuel in wet nitrous oxide setups

 

You probably wouldn't get controllable FRs because you can't control how much goes into each piston. More important with gas than nitro or meth.

 

That's what I was thinking too. It wouldn't diffuse through the plenum propperly.

 

Depends on where you fire it and how its mounted

 

Exactly lol.

 

Thought I read somewhere that someone tried spraying fuel like that and it was a no go. Something about the manifold dividing the fuel. You are more knowledgeable than me though gio, I really don't know one way or another.

 

That was with the meth injection being too close to the throttle blade (that was me that said that). As long as either are more than 6" upstream from the TB, the fuel is evenly distributed.
I would honestly put it a foot away or more just to be safe.

 

You would also want a good nozzle that atomizes the fuel well.

 

Think idea is 6-8'' from TB really for meth/water anyways.

I still think it would be a PITA to tune

 

No way dude. Those kits come with a pack of different sized jets that let you dial in the perfect AFR. You can hook up the solenoid to a hobbs pressure switch and have it kick on at 4 psi or so. No tuning units to deal with. Watch an installation video of a wet shot Nos kit and just picture the turbo feeding the engine oxygen instead of the Nos... it's stupid simple to set up.

 

Yea but not ideal and not accurate.

At some point you have to realize that to REALLY get the best of the the turbo, you have to actually stop and be more precise with it. Especially if you want your moneys worth from it and it to be at least semi bulletproof reliable.

Sure it works..but at some point, the margin for error will catch up and become well...just and error.

Id rather do it right and hard than easy and cheap.

 

IIRC, no tuning is needed for wet shot . If you get a well made product, the nozzle will already be tuned to allow the proper NO2 and fuel mixture per shot. No tuning needed on the ECU side. Different story for a dry shot; you have to be nuts to run one of those.

 

Oh yeah for sure. No fine precision about it, but the average clown with a chubby for boost is only go a care about WOT pulls. As it is, our trucks can give us 11 AFR in open loop boost up to 5~ psi with the stock fueling and tune but with the exception of hooking up the FPR hose to a boost reference to drive up the fuel pressure parallel to the manifold pressure. That takes care of most of the potential lean spots within the powerband.
I never said it was a great idea, but it's definetely doable nontheless. The engine isn't going to know if it's getting it's fuel from 6 big injectors or 6 stock ones and a nozzle before the throttle blade... as long as the AFRs are good then it's cherry.
I didn't put a turbo on my truck to boost 1 or 2 psi, I put it on to floor it and go fast.

 

Not talking NOS. Talking about using nos style injector for more gas.

 

Oh. Got a little lost in the convo. A 7th injector mod is kind of silly. Just get new primaries.

 

Urd makes a 7th kit.....

At $895 you could get a piggyback and bigger injectors. Urd never ceases to amaze me with their crazy pricing

 

That's for the S/C'er but yeah, a little pricy. Cheaper than the TRD kit though. However IIRC, neither were able to completely eliminate the high load, low RPM ping associated with the TRD S/C.

 

I was thinking of something like that was what gio was thinking, of coarse with nos. Wouldn't it be similar? Nozzle vs injector?
