Unlimited vs Swamps

[Homesteader]

Well I'll be doing 300/200 on my build. It was between Unlimited and BDP (Cass fullforce)Havent really looked at Swamps maybe I should. I dont have any exrerience with these injectors so I need to read up more and talked to guys that have experience with these stick.

The rest is 100% tuning. You should have darn near complete smoke free driving with the small 200% nozzle.

Exactly.

GearHead Tuning on mine and it smokes like a stockish truck w/ say an 80hp chip that just happens to haul some serious ASS!

Also, I have no fast mods.

I lovvvvve the 200% nozzle...

have a set in my Excursion, and with a (very) slightly laggy 71mm billet wheel S300...it's crystal clear on my daily setting...cry-stal

and since I'm only running 200cc's of fuel (yes...a 200/200 LOL) the charger cleans every last drop up at WOT in a hot tune...

if every (inj) customer would do studs..I'd put a 200 nozzle on everything.

what cc of fuel do you think the 200% nozzle starts to become a restriction?

I'll be doing studs....Now to find who I'll be gettting those injectors from

what cc of fuel do you think the 200% nozzle starts to become a restriction?

at what duration? pressure? rpm? application, power level, etc, etc...

I hope that my tip is ALWAYS my restriction in the fuel flow on my injector - otherwise the fuel would just piss out the end and have no atomization. oke:

at what duration? pressure? rpm? application, power level, etc, etc...

Seriously - any app that would require more than say 215-230cc in a 2ms time window at 3kpsi requires a bigger tip. And I could argue those numbers are a touch on the high side, but more often than not most guys are in it for the drivability and will be just happy with the 200% power level.

I agree with Dave - the 200% nozzle is most likely the best balance between drivability and performance there is going right now. If I had a street truck and needed new sticks it would have 200% tips on it, no questions asked.

Well i guess i wasnt being specific enough, but i was just wondering how big of an injector you would "recommend" a 200% nozzle for. Your running a 200cc injector, is there danger of emptying that before it can refill or is it all in the tuning?
Would a 400cc injector with a 200% nozzle really be practical? Is the nozzle a good way to keep it daily driveable while still having lots of cc's on tap?

*I* wouldn't run a 400/200.

300/200 yes...350+/-/200 yes...400/200 no...

400/400 yes, 450/600...maybe.

the 700cc hybrid hybrids I built a couple of years ago (3?) were running a 4 digit nozzle.

And that is where we differ - I personally like the 400/200s for guys that are stepping up with plans to step up even farther later - cut out the machining step and just a tip change would be needed later on. The truck I just worked on is a prime example - it has 400/200s in it right now to get things dialed in and at some point in the future (this summer, or over the winter... don't really know) - they will be stepped up to 400/400s. Its a different approach to the same ultimate goal.

:whs: I Wish now I would have steped up to the 400cc over the 300cc injectors and just kept the 200% nozzles.. Then if I would ever want to i could got to 400% nozzles.. That way I would never have to worry about needing more fuel..

Was that mentioned anywhere before now?

if "a" consumer was going to stay WITH 400cc's...or a 200% nozzle...

would you really recommend that combination together long term?

Hey, WTF? You never told me that when I bought my chit

I wouldn't recommend that combination for long term - but there isn't any harm in running it long term either. The tip is limiting the fuel flow for the injection event and a there is a decent portion of the stroke of the injector not being used. I threw it out there because so many guys want to go up in steps (in fact I recommend that for anyone) - and someone might get the impression that the total volume of the injector actually has something to do with the amount of fuel that they get out - its simply an option for anyone buying injectors - and its one that I recommend to anyone even considering stepping up in the future after a lengthy discussion on their wants/needs/desires/goals/truck usage/etc... Hell it could be 5000cc of total volume on a 5:1 hybrid at 3kpsi with a 200% tip and the same volume of fuel will be spit out at 2ms as the 300/200 hybrid setup the same way.

LOL...sometimes...the customer is always right...

thank you for stating the obvious (for others' benefit)...

some people have no idea...

While I agree that there isn't any 'problem' with running x000cc inj with a 200% nozzle...from an injector durability standpoint...

there would much more likely be an issue related to the tuning asking for too much PW...which would be pissing a lot of fuel 'late' into the cylinder...creating higher than necessary EGT's, an a chit ton of smoke...without any real benefit as far as actual power increase.

but if the tuning was set up to not ask for >x_ms...(or whatever duration which was req'd for ~300cc's)..it would be hunky dory...since the tuning would electronically 'neuter' the 400/200...down to a 300/200 +/-

 

[BMac]

Just the Tip eh LOL

 

[TARM]

I know I went with more volume for the reason I am planning on jumping up nozzles. But if I was going to stay with a 200% for sure and it can only flow 200-230cc/2ms/3k icp not much need for more than 300c to still give a cushion. I started with the 200% as has been said because from everyone I talked to felt it was the best balance between flow and injection quality / performance and daily driving. Yet you could still as Dave put it to me " you can make some stupid power with them" "Stupid" may not be a positive in most things but I likes me some stupid power. Enough for me to do some real stupid things with

 

[Gearhead]

Tuning has come a long way. Just because you have 400cc of fuel available doesn't mean you have to call for it all. Same reason that the factory injectors have any room for a power increase with just a chip.
