Hi all, Would removing the mesh from inside my Hilborn 6A nozzles cause any flow issues, or have any negative effects? I’m assuming it’ll increase flow. Here’s a pic for reference. Many thanks. Sent from my iPhone using The H.A.M.B. mobile app
I believe the mesh helps atomize the fuel. if you want to increase the flow , raise the fuel pressure or go with a bigger nozzle.
Of course the mesh is meant to catch trash before it plugs the nozzle. If you want more flow, why don't you get bigger nozzles? Or if that's your thing, drill yours.
I’m trying to clean my nozzles and if I remove the mesh I’ll be able to clean them so much easier. I don’t want to increase or decrease flow, just wondering if I remove mesh (for cleaning purposes), will this effect anything? Sent from my iPhone using The H.A.M.B. mobile app
Enderle nozzles do not run screens, a lot of dirt track racers remove them for ease of maintence and to eliminate them plugging. most small trash just blows thru the orifice, anything bigger and plugging the nozzle, you need to up you maintence game. The deflector tip break up the stream enough for atomazion , straight thru would need screens
I can’t see how you’d replace the mesh without separating the 2 piece nozzle that’s been soldered. Sent from my iPhone using The H.A.M.B. mobile app
Do yourself a favor and switch to enderle nozzles and holders, the holders stay with the manifold and does not wear out the threads, The nozzles easily are removed for cleaning and/or changing the nozzle area and they are cheap @$7.00 ea, vs $30 for Hilborns. Hilborn plays with fuel pressure to tune, Enderle is a both nozzle area and pump pressure. FYI Holley Ind just bought Hilborn, how that's going to affect the racers IDK
If you have to run Hilborns with the screens, Harbor Freight sells a "sonic cleaner" that does a pretty good job of getting them real clean
That’s a massive difference in cost re nozzles. Definitely worth looking at indeed. I’ll get it running with the Hilborn nozzles first and look at swapping them out. I think I’ll remove the screens altogether. A nightmare to clean otherwise. Especially going forward. Interesting to see what happens to Hilborn with the acquisition of Holley. Thanks for your help.

It's not a big deal to unsolder the tips and then put them back. Propane torch works fine. When I was making the injection mainafold for my Dodge I decided I wanted to point the slot differently than they were. In that case I just heated them and rotated them without removing them. But then I decided to use brass JIC fittings. Drill them for the Hilborn tip and after that I could use regular AN fittings instead of the Hilborn thread. Worked OK. So I made some tips of my own. Never tried them. Looked good. Would have neede some time with a flow bench to see how I did.
A good filter will help a lot....with 80% the holes in the nozzles are big enough to let just about anything through them and you don't need any screens.....
When I have some spare time I’d like to separate one and have a look. A fun little excuse to loose some time Sent from my iPhone using The H.A.M.B. mobile app
