ok mister running a large injector will put them out of sync with the valves lmfao

yea that was a brain fart..i'll admit it...but you try taking two calls, calling them in as impounded to PD, releasing a car over 6000lbs that was dollied and the people want to know why it was $250 and thinking about fuel system tech all at the same time. then do that 8-8 every day and see if you dont **** up...that actually came from my specific build. i'm having a problem with the cam cause it has no cam sensor pick up on it. so the injectors are firing all willy nilly.

but back to my original point running a 60# injector and only needing 42;s will not make it run lean or be inefficiant
i donno u but id rather have a big injector then not enough

:orlyflag: :dancinglock:

to an extent...if your duty cycle is to low they will spit, if its too high they will spit I worked mine out to run at 75-80% at stock fuel pressure.

the more you argue the dumber you look also

i realize this but i just don't give a *****

then what makes you think he does?
:threadsu:

not if the fp is right,and the only issue may be idle tunning if the injectors are to large u cant get the pulse width low enough.

if the injectors are to oversized u wont be able to open and close them fast enough,basically u will just crack them open resulting in poor idle and very hard tunability

an lt1 needs a 50# injector open 9.2 msec for 100% ve at wot add in the 1.1 msec opening timeand u have a 10.3 msec pulse width
thats without any enrichment running a 14.7 afr
now for 12.0 afr that would be closer to 12.3 msec or about 42% duty cycle on the na motor

bring that down to idle and ur looking around a 1.5 msec pw at idle + the 1.1msec opening time plenty of time to allow for idle tunning even though it is a lil on the low side by about .7 msec

idle pw shoudl be around 2.3 msec without opening time for ease of tunning the mixture,with low pw time the only thing that happens is an enrichment in the ve bin becomes exaggerated a 1% increase in the table could actually become a 4% increase in injector flow or decrease depending on which way ur going

but at idle ur already dropping fp when vacum is aplied to the regulator as long as u have an adjustable fpr its fine u can just take out an additional 1-3 psi of fp at idle

but 50's are well within the range of being tunable at idle something like say a 60 or 70 pound injector would make for hell trying to tune at idle with ultra short pulse widths

Nice job Dave....glad to see the car is finally starting to come together and put down the numbers.

OMG HE SAID SOMETHING NICE :willy:

42% is not much of a duty cycle and certainly not with in the range that an injector will be efficient. 60# at 42% is also not equal to 50# at 100% unless the fuel pressure referenced is massively different.

Sounds like you just decided to over complicate things with a Vafpr that you didn't need and the wrong sized injectors that you most likely picked up with all of the other second hand stuff you used in the super combo.

yea thats what i was trying to say...:moon:

lol hmmm who else did we say this to? it was a while back and i dont think its even running

funny funny....which one of your cars runs again?

Ron had his T/A at the Roadhouse.

this comes from somebody who demolished 2 of them! :nod: :lol:

correct, and that was a nice turnout too

both of them run and drive fine. one gets 32mpg, the other 26mpg and runs low 12s all day :)

1st off I wasn't driving the T/A and at least that car got some use and was turned into something better as opposed to rotting away in the weeds...

and the camaro being a bastard right now she'll be out to play soon enough

lol it wasnt "rotting away in the weeds." the car looked so much better before you got a hold of it. i remember cringing along with a few njfboa members at the track when we saw it there. i remember putting the car on the lift and showing you and you bought it. it wasnt like u bought it blindly. that camaro has been a bastard for a pretty long time now.

a yea and a few months, and I know what the car looked like when I got it, and when it was wrecked...your ****ing crazy if you think it was better the way it was

if its as bad as u say it is, then why on earth would you buy it? Only a complete idiot would do something like that... my trader feedback on every forum is 100% positive with nothing but good things to say, and people who know me (which would be quite a few) know i wouldnt make up stories.

internet fights!!! ....ducks....

What happened to the geometry guy and his 65 degree six banger?

i didn't say you were making **** up...but when I got the car it was faded black with ****ed up GFX

does that look "worse" to you?

that and it went from a high 15s car to a 13s car that doesn't consitute worse to me
