Gen 5 Camaro Internal Engine Tech - What are stock injectors good until?

I have

644/614 230/238 111 Comp Cam
Ported TB/Intake Mani
Cold Air Intake
JBA Big Boy Headers (Stainless)
3" out the back
Underdrive Pulley

Should be over 500+ rwhp

Your stock injectors will work. I believe the same injectors are used in the LS7 and it has 505hp from the factory and they aren't maxed out. If this is in your 2010 Camaro SS, you could also upgrade to a ZL1 fuel pump.

If you are tuned, what was the duty cycle? If you aren't tuned, check the duty cycle during the tuning process.

500+ on what planet? You might see 460-470 out of that combo.

have seen it, and cam only they are making that plus im getting tb/mani and underdrive.. this isnt a little cam

Not on any legitimate dyno they aren't. Sorry to bust your bubble. This isn't a corvette, that cam isn't large, and although texas has nitrous air, it isn't going to happen.

Good-sized cam but 500rwhp I'd say only if the dyno operator sprays your car with a 50 shot at the same time.

I agree, thats a 470 to 480 setup on an m6, 450ish on an auto.

BTW, I run a 230/244 on a 111lsa. I put down 463 on 92 octane. 474 on e85.

whats your lift rhino? and cam with bolt ons (no underdrive or ported mani/tb *ls2portworks) hit 470-480 have called 2 places (texas speed, LMR) have seen many dyno's.. i guess underdrives and the porting does nothing... underdrive lets say is 5 and mani tb is 10 (which i think is low balling both..) iv built 5-6 500-1100 hp cars and have always hit my mark and the cars have ran out real hard

not saying yall are lying, but if it doesnt work guess ill port the heads then spray it for shits and giggles since money isnt a issue

Well it depends on the dyno...lol. .588/.607 lift on my cam. Ported tb and mani may be worth 7-10 and I dunno on underdrives. Is this an auto or stick car?

i agree; 460-465 would be my guess. Vettes see better numbers than Camaros- even if they have the exact same mods/cam. Theres also a discrepancy in numbers from one dyno to the next; some dynos tend to give happy numbers.

I agree, this will not hit 500 on stock cubes and that cam. Shit I had a 408 in a vette with a 236/244 @ .625 that made 49x....on a realistic dyno. That was with heads, cam, LTs, FAST intake/tb, etc etc....

So what are the 5 Gen Camaro injectors rated at 28lbs/hr?

No they are 42 lbers I believe.

LS3 Injectors are 41 lbs / Hr.

ok i understand yall have built some cars

my LS1 H/C Intake (5.3 heads) with a 228/230 598 lift cam made 455/412 on 3 different dyno's from Dallas to Houston explain that? Ls3 has better heads, 90mm intake and a bigger cam and im using better headers... is it drivetrain loss? please explain

my buddy hit 495 with a 383 2 dyno's just stating some hard facts i have

Yes. It's drivetrain loss.
You should see ~530 at the flywheel with that setup, but by the time it gets to the wheels you're only looking at 485-490ish with a VERY aggressive tune.

Ditto to what Aries said. The IRS seems to have more loss than a live axle for what ever reason.

so what did this put down?
