well i really wanna get tuned asap for 5-6psi and was wondering if the stock injectors will be fine for this

 

depends on turbo to be honest with ya...ill bet no matter what youll be running a very high duty cycle on em..

look at it like this, peeps are running 550cc injectors on t3/t4 turbos (various trims) and are running into problems fuel wise at around 9-11psi (depending on trim).

if i were to place a bet i would bet on you maxing out the stockers easy on 6psi with similar turbo.

16g is small enough that the overall air flow that it can produce at that low of boost will not be as much of a strain on your fuel system as say t3/t4 that most are running. even still im pretty sure its still very taxing on the stock injectors.

 

I have 630cc's for sale if you're interested. Also a Unichip which is tuned for the 630cc's for up to 8-9psi. PM me.

 

sorry i have an 08

 

Yeah that would be an issue.. lol

I'll have an FIC with the same injectors for sale in about a month or so too. You'll need an '08 harness tho

 

FIC sounds good ummm i dont need a pnp harness im good with wiring

 

you can run race gas on stock injectors, target wot afr 12.4.. im sure you can run around 9 psi

 

my stocks maxed out at 8 psi on a 54 trim turbo

 

oh wow....thats not bad at all...i really wouldnt have thought that you could get away with stockers and a 54trim at 8psi...

 

like i said they were maxing out there......at 8 psi and around 4500 rpm it would start leaning out to 13-14afr

 

sorry for bringing back this thread.
im going to run the 16g turbo and probly not go more than the 6psi. i have the emanage and want to install this kit but i wanted to upgrade injectors would it be better to leave the stock ones and get a intercooler since the stock ones r good untill 8psi?

 

upgrade the injectors. do you plan on running a 16g forever?

 

im going to keep the 16g forever!!!! i want a 215-220hp range thats enough to have fun and still autox. i just dont want my car to explode!
i thought the intercooler would be better than the injectors.

 

i was at 225 hp nearly maxing my 440 injectors..... im at 240 and now my injectors are over maxed out.... sooo moral is stock injectors wont keep for 220 hp just get trd injectors atleast

 

so all this stuff about the size of turbo and type doesnt matter?
arnt you using a pretty big turbo?
i just want to make sure of all this stuff before i buy things i dont need.
i checked the rc website and they have a calculator for injector size but i doubt i did it right....lol it said i needed huge injectors for the 220hp i want.

 

size of turbo matter only for psi wiase so liek 16g on 6psi = decent with stock injectors and 601-1 = very lean with stock injectors at 6psi this is all due to the fact that one makes more power than other


injectors are usually rated with hp... and stock injectors are good for maybe 200-210 wheel

 

Can't be rated by hp alone.
How much will the trds hold then?

 

Here are some conservative ballpark figures from RCE's calculator using .60 BSFC:

OEM 370cc = 210bhp @90% IDC
TRD 410cc = 230bhp @90% IDC
440cc = 250bhp @90% IDC

Subtract 10hp for MT and 35hp for AT to get approx. WHP.

BTW, you're right. Injector sizing isn't based solely on HP. It's a combination of HP, fuel pressure, brake specific fuel consumption and IDC. Even injector type (saturated or peak & hold), resistance and response time factor in to some degree.

 

Hi,
stock ecu + piggyback type tune box, greddy emanage blue.
what is the max cc of the injector can choose? because due to limitation of tuning while idling to 0psi time, it may minus a lot on emanage setting, so anyone have any idea?
Thx

 

uhhhhh.......what?
