16g Injector Size

[spoolintsi97]

What is the recommended size injector for the evo III or are the stock fine

If you plan to go bigger down the road then 650's but have fun controling them with an AFC at that level. If you never plan to go more then a 16g then 550's are perfect.

You can get away w/ running 550's but a E III can max them out. You may be better off to go w/ 650 as the E III will not max those out, and are available if you ever decide to go to a larger turbo. IE a 50 trim. I'm not maxing out my 650's yet w/ my 50t.

And yes, 650's w/ an AFC will be hard to tune for, but not if you have a keydriver chip, or equivelent w/ injector compensation. Then tuning is a breeze.

If you want to go over 16psi, which I'm sure you do because you can't utilize the E16g's potential without going halfway through the 20's you're going to have to get rid of the stockers.

Yes, I forgot to add. You must get rid of the stock 450's. Shit, even the 14b at 16psi is too much boost for the stockers.

Hows that 50 trim compared to the evo3 project_tsi? I was under the impression that they were basically the same turbo but the 50trim is more pump friendly due to its larger compressor cover?

The 50t is a tad larger than the ol EIII. It does spool a tad bit slower, I can hit 25 psi by 4000 r's. But no, the 50t isn't really that much bigger than an evo III, but it is dif. and can take a bit more fuel too! I plan on upgrading after the winter to 750's or larger.

To really have fun with a B16G, get 650's or better. I've actually had a fairly decent time getting the tune within a good measure with the S-AFC.

The B16G doesn't really seem to be in it's element until around 20#'s or better. I've been sitting at 22#'s since the install and it pulls like a raped ape.

depends on what kind of fuel you'll be runnin. on 110 @ 27psi, 560cc off of an EVO 8 and with a right tune will be perfect. on pump gas, w/ 560cc, 20psi is safe. get the picture? hopefully, you will find this as useful info.

I have been wondering the same thing for when I get my fuel setup. I have the EvoIII and want to run it around 20psi, I have the MAFT (blowthru) and im getting an AFC. I would like to get 650's to be safe, will having the MAFT (and an AFC) make it an easier to tune than just having an AFC? This will be my first time tuning, I dont want to start off with 650's if 550's will be easier.

i'm running 510s with mine - no problems so far

With an EvoIII? At what psi?

Honestly, i can tell you right now most people are gonna say 650cc. They have a good reason to say that, seeing as how they'll take whatever the Evo will shoot at them.

It all depends on your goals really, if your looking for a mid/high 12 second car that will be significantly easier to tune, just get a set of 550cc. However i highly recommend if your shooting for more then 360ish horsepower you consider sucking it up and getting 650cc's and getting a good tune with it.

I have 650cc's, and i can tell you they are pretty difficult to tune with only an S-AFC/Datalogger combo, which is why i am looking into getting an EPROM Ecu / DSMLink at which point bigger injectors are welcome!

Whatever you choose for your setup, best of luck to ya!

EDIT: Spoolin98

In all honesty, i am also running an MAFT/SAFC combo to try and tune my car and i find it pretty difficult. You'd honestly be better off picking up a EPROM ECU / Keydiver chip or if you have rich blood DSMLink. Hardest part of tuning these injectors the fact you get abundance more timing then stock, and a smooth idle is hard to get without being pig rich. There are ways around it, but i feel the best way to compensate would be with a chip.

Thanks for the info man, thats exactly what i was looking for. I think im going to just get the 550's or 580's? Whats your thoughts on that? Im wondering how many lbs of boost i will be able to run before maxing out 550's/580's? I have a 255 and AFPR not installed yet.

 

[power=dsm]

i'm have the 510 injectors and running 18 psi and alot of room for more boost. I also have a huge fmic and 255 rewire. on my eg16

Is a 50 trim really only a 'tad' larger than an evo 3? Sure people have reportedly gotten them to some 40 lbs/min but that's probably not on a stock intake manifold or cams. More than likely a 50 trim will be a significant upgrade from an evo 3.

550's will be fine if you only pan on running around 20psi. i had 550's and a 190 pump and i was only running 89% duty cycle at 20psi with dsmlink on my evo16g.

though if you want to do more, say 25ish, you will need the 650's.

Thanks for the info, i planned on running 20psi, so i think 550's will be sufficient. Plus they will be easier to tune with.
