To be honest im just going by what i see, down here everyone does **** half ***. Like a buddy of mine had a LS3 T/A with a big cam in it and ported ls3 heads (done by who knows what, and not even flowbenched) untuned he had the OEM ls1 injectors maxed out and he would race randomly till it detonated and knocked a rod out the side of the block. I know...retarded..
Your buddy is a moron.

How old are you?

Yep i know, it was a dumbass move, all he needed was to spend $300 on some injectors and retune. He's throwing in an LQ bottom end and turboing it. Im 21.

It's not really the duty cycle you have to watch. It's the enrichment. It can only enrich up to 25%.

That's wild, in the honda world duty cycle is everything when your maxing out injectors its like a ticking time bomb. In the honda world ofcourse.

Duty cycle matters, but on a NA, not as much as on a turbo car, or spray.....or so I have heard. My **** blew due to spun bearing, I never had any fuel related issues on my set up. I WILL be doing fuel for my new set up though.

Duty cycle matters so you don't cook your injectors. If you drive the injectors to long for fueling they can fail.

Btw......I never said it didn't matter. So get your heads out of your *** and try to comprehend.

I know, yet somehow the motor managed to live from 08 till a few months ago, about 40k miles on the heads cam set up, and only went due to a bearing issue. No idea what was up with it, but it still managed to trap 118 in so so DA.

Glad you went there. I've been trapping 120 or more with the same motor since early 03. Ran for years with injectors @ 107......apparently you guys don't know what duty cycle means. But that's ok........all of you seem to be doin a better job than me .

Actually put the motor in around mid 02. Almost 80k on her now and the last 6 - 8 times to the track it has set either a new best in et and/or mph. Last time out it actually trapped 130 and change........but I know nothing.


Continue on gentlemen......lmao

If your engine is at an RPM where it takes 50 milliseconds to complete a cycle (that's two revolutions, because two revolutions = 1 engine cycle) than your injector is at 40% duty cycle because 20 milliseconds is 40% of 50 milliseconds. The injector's open time is 40% of the time it takes or the engine to complete 1 cycle. Once the rpm reaches a point where it takes 20 milliseconds to complete a cycle, you are at 100% duty cycle and the injector is staying open. If the engine spins any faster, obviously the calculation passes 100% because the engine is taking 15 milliseconds to complete a cycle, but the injector pulse width is 20 milliseconds. The injector is still static open at 100%, but the calculation can surpass 100% because the engine is spinning faster than the injector can open and close.

Rudimentary explanation, but it's simply because it's calculation of injector open time vs rpm

Nice that your stock motor has lived for so long, I don't see what the point in your post though is. I drove the **** out of my car, got it in jan 07 with 53k on it, now sitting at 114k I believe, cam went in around 70k I *think*, sometime in 08. You put 80k on your engine in 9 years? At least it still lives, and at least it's fast, but other then that I don't know what point you are really trying to make...And regarding my set up, fuel didn't kill my engine, some other factors did.

his friend had a bolt-on srt4...we ran and he actually asked me if the car was supercharged. i loled.

The problem is that duty cycle can be manipulated with other values in the pcm.
