Undefeated got a reaction from Slow250XC in Efi 2barrel efi kits verse Holley carby.
Further Update: grew up in the States and have family there so im all sorted now..got a good deal!
2 barrel sniper master kit is sorted and on way.. I will do a thread on OZfalcon to show it’s fit up.
I could have gone the 4 barrel version, but for what I’m doing there’s no point.. the flow is around 500cfm from a 2 barrel Sniper and I suspect it may atomise better on a mild 4.0 or 4.1.
im keeping the Redline Tourqer manifold for the moment to compare against others at a latter date.

Yes it’s going well .. wonder what kens thinking? Think we went to school together? Or that yellow 302 Mazda from the older brother rings a bell from the 90s at saint patty’s blktwn? Great, but show us some insight on how these times were achieved with the Bonnet up,
either way.. single 4brl??

don't let BGDAV see it, he's already lost weight on the "car parts diet" (where you prioritise car parts over food)

LEGEND!! And that is what a good forum is all about, genuine blokes trying to help each other out. We are so lucky on this forum coz some other forums are all just negative crap and blokes having a pi$$ing competition to see who is better than the other ☹️ -

Exactly, the big filler hose gets a simple plumb into it ,and the return squirts in there.
(nothing to do with the tank venting /charcoal system)
the complex part for me atm is working out what air cleaner system to run, and how I’d like this motor to look, I like the idea of a blow thru style carb hat connected to a k&N pod or cold air box, but a nice air filter looks good too...and to be making sure I’ve got the right dizzy and Holley connector with plugs and leads to run programable ingnition.. it’s recomended to just do the 4 wire hook up first.. so a lot of guys don’t run the ignition side of Sniper EFi I noticed..( if not controlling timing, that’s a simple 4 wire hook up)
and whats up with everybody bagging REDLINE??! This is a good little Aussie company success story.. who has supported the crossflow motor and others, and I’m happy to have there products on my old car..changing to any manifold is not going to net much on a street motor, the efi should atomise better than a 40yo old carb.

I’m trying to figure all that atm..
which dissy to run.
(Side note: yes I’m aware of a std Barra that recently run 350hp with just a carb and cams here in QLD ..but im no drag racer, it’s intresting to see what may be out there for the future.)
Back on topic: for ignition control , it’s going to have to come latter.
here’s the video of the Holley tech rep showing Phasing and dwell.. atm I’m scratching my head TBH as to what Distributor to run.. EST , TFI.
I’m checking on Holley Sniper forums and seeing what USA Ford guys are doing, I will probably contact Holley directly and put it to them.
In years to come people can look at this...hindsight makes a expert.

Well finally that Walbro fuel pump arrived today with the mounting kit, so now it’s time to start working on the car.

Is that smart to do?
I know its same same but your not regulating pressure at the injector.
Im not rocket scientist but pressure loss at the injectors will not be rectified until its picked up at the pump end..... too much room for error for me.
Thats why its always in the fuel rail.
Never listen to the chev badge.... it is Evil I tells ya! Eeevvvviiiillllll......

It’s a Return line system.. same as normal EFI..the return line runs back to the tank. It runs a reg inside the Carb so no reg required to run it NA.
there is many instal vids on YouTube, as I do each part will link a video on that subject.

With my o2 sensor in closed loop my cruise driveabilty is poor. The ecu is constantly altering the a/f and varies quite abit depending on temps. I also have low comp and mildish na camshaft which doesnt help.
Before my current setup i changed from a redline 4bbl manifold to aussiespeed and they are definitely a better manifold. I agree that its the way to go but it can be made to work for now.

I think he means the filler tube, which I can't see a problem with. The breather should come off a tree of lines that screw into the top of the tank via a small manifold, off to the charcoal canister.

Undefeated reacted to ando76 in Holley Sniper EFI
My exact point. If you follow the guidelines and target 12.8 you could burn a cylinder with the Redline. Modify it to 12.0 and watch 1&6 in particular and you would be on a winner. But if your spending the coin to have a nice cruiser, why not spend the coin on a manifold with even flow-balance. It's not all about making hp&torque although that is good. It's about making a happy engine. Happy engines make more power and torque and use less fuel to do it. That makes for a good cruiser in my opinion.
The gain most experience when going to triples is largely due to even cylinder fill.

Undefeated reacted to ando76 in Holley Sniper EFI
Yeah. There are a lot of redline manifolds out there, because once upon a time, that's all you could get. Then blokes like Ian 'moo' Moody (ultraflow) and Ray Hall started to make manifolds that actually flowed close to even and weren't just a spot to put a carb on.
The new Aussiespeed 2 barrel manifold is an awesome bit of kit. Very even cylinder fill. Yes they are expensive, but hey quality costs and spending hours on a dyno chasing your tail is also expensive. If the budget isn't there I'd be searching for a second hand ultraflow.
I may be playing devils advocate here but I see problems ahead with getting the tune right with the Redline. Why? Because the ecu will be getting a read on the mixture and will then trim to suit and it may well trim to the point that it burns the lean (better flowing) cylinders. I've spent a considerable amount of time carb tuning these engines and doing plug reads and egt monitoring to try and get the best possible tune when you don't have ideal flow balance between runners.
Its not uncommon to run different plug heat ranges, richer afr target than you normally would go just to try and keep cylinders from running lean. I've known builders to run less comp on certain cylinders to address manifold imbalance. Of course I'm usually dealing with engines that spend most of their lives between 3500&6500. It sounds like this engine will not be given a hard time so it may all work out fine.
Id be keeping a close eye on plugs all the same. The algorithms and target afr's might just be too smart for their own good. Having said that if you can get into it and tell it to target 12.0 instead of 12.8 then it should all be fine.

So last piece of the puzzle before installing, I decided to do my own fuel system. I believe the fuel pump Holley normally supplied with Sniper are Walbro pumps..
Looking at what others have done, and for a good budget pump , I ordered the Walbro GSL392 ( 255) and in-line mounting kit.

After looking at some options I decided to go with the Holley Sniper EFI kit..
for those unfamiliar with these this is the new Holley Carb replacement system. There’s a bunch of Videos on YouTube about the sniper EFi, but a quick run down:
yes they can be boosted, they self learn, they can control ignition too, they are a touch screen like your IPhone.. for deeper tuning they plug into your laptop and once there can be tuned even more.
I spoke to Holley directly and the 2brl kit was the suggested option. It’s good for it’s 350hp and flows 500cfm.. ( they can go more boosted) , They also informed me that they havnt sent the 2barrel version to Australia yet.. so this is the 1st one!
In this thread I will try to go through my process of installing it.. some say it’s a 2 hour job to install and drive.. I never work that quick.
