Dyno tune I'm hoping to be between 250 and 270 at 8psi
My buddy has a set of rc440s
Wi they big big enough

SiRCiviC94

Oh yeah. Even ur stock injectors will push that just not reccomended

DELshaneSOL

Ok I was reading somewhere and they said 250 was max they must have ment 350

SiRCiviC94

For stock injectors? I'm no expert but 440s probbly
Max around 350-400 range but you shouldn't go past 80% dc incase

Put that sir at 300hp with a ram mani 8-9lbs should see that easy

DELshaneSOL

It's on stock motor so don't wanna go to 300

Umm. No. not even close. you'll freeze them open. Not only is it not recommended, but not possible without serious failure.

Make sure your fuel injectors are sized appropriately for the power that you are trying to make. Below is a quick general guideline for injector to power rating given a base fuel pressure between 40-50psi:

240cc/min (stock): 170-180whp
310cc/min: 200-240whp
370cc/min: 250-275whp
440cc/min: 300-325whp
550cc/min:350-375whp
650cc/min: 400-425whp
750cc/min: 450-475whp
1000cc/min: 600whp
1200cc/min: 700whp
1600cc/min: 850whp

Thanks to Evans Tuning for this info.


youll be bored with your power after the 2nd week (if you dont blow it up by then) so buying larger then needed injectors is recommended.

Ok I'm going to go with the rc 440s then run 260 hp
Is that safe for a stock motor 260hp I'm talking to the wheels hp

your tuner will know whats safe and what numbers youll get according to your set up.

If it were me, id go for 550's


Edit: B16's have seen 300hp with your set up.. so youll be fine

DELshaneSOL

Well my friend owes me money so he prolly not gunna pay me do might as well just take his 440s for now

DELshaneSOL

I could always sell them for bigger ones later on

you should be okay just dont go past 80 percent duty cycle on the injectors.
my buddy has a gsr block with a b16 head and a turbonetics 60-1 using 450cc injectors at 9lbs and his duty cycle was just a little bit over 80. didnt have any problems but i heard anymore then that and you will be over working the injectors. Make sure you get the injectors clean and tested first though.Over here theres a dr.injector and he tested/cleaned all my injectors.

I had fuel to hit the 100 pills it seemed lol on all stock fuel system. Lmfao freeze them open moar fuel!

B series motors are raw as **** 300 at the wheel I wouldn't break a sweat. It's not like we're holding that power for 10 mins. More like 12.5 seconds

rich7777

Sometimes i get the impression you're on 100 ecstasy pills.

SiRCiviC94

It was basemaped for 100 so ran in the 10.9 afr range spraying 65. Works like magic lol but any more on stock fuel set up ull hve to be a lil crazy

rich7777

I think i need to be tripping to understand that. Sorry..

dantamparacer

What fuel, that well make a difference. Ethanol requires about 25-30% more fuel than 93oct

DELshaneSOL

93oct

I would run at least 450cc injectors and they will be close to the limit. 550 or 750cc injectors is much better and safer. The stock injectors will not cut it for any boost IMO.

DELshaneSOL

I'm going with the rc440 I'm getting them for 100 so why not I'm only trying to get around 260
