This may seem like a dumb question but to those who know:
Would getting 33lbs injectors help my chances increasing HP/ Torque on my current stock setup?
If not is there anyway gaining more power with 33lbs injectors, new chip, intake?

 

bigger cam, bigger intake and/or bigger displacement then a new chip

 

I read an article in chp that indicated an increase in injector size equated to a small increase in horespower. However it was nothing you would feel in the seat of your pants.

33# You'll loose power man, wont atomize worth didly when you adjust the duty cycle enuff not to flood the car

Only way they'll work is to basicaly change the whole enigine around to one that needs that much fuel, AKA heads, cam, bigger displacment, ect ect ...

 

In other words, change a few main factors before dumping more fuel, thanks guys I wasnt 100% sure about that.
Thing is if the stock computer only tells it to dump so much fuel as a 22lbs wouldnt it just run the same until you programmed it to dump more?

 

It would be dumping in more fuel . Then the O2 would read it rich and , then cut back fuel , but it would still be baseing it on the 22lb injectors being in there.

So it would be a mess. Could even wash the rings out and fry'm up .

 

I can sum it up, would work very very badly

I'll try to break it down as understandable as posible, try to use english instead of tech talk

If your computer is set for 22# Injectors running at 85% of there max for a decent life span. then you pull te 22# and stick in 33# without adjusting the computer. It will still be trying to dump 85% of 22#, but 85% of 33# will be alot more fuel, thus washing out the car. Your O2 sensor will try to compensate but ... ever seee an ant try to take out a beehive on its own??

Then there come's atomization, lets use a garden hose as an example, with no nose on it the water just kinda falls out of the end, eh Put on a nose (smaller end) and it shoots out with nice volosity. now pretend thats gas and on fire, the droopy gas will burn but like crapola, but with the smaller end on it you got yourself a nice little flame thrower

 

and if you lower the constant(%) for a 33lb injector then it will just drip instead of spray..

 

Yup, hence my flame thrower comment

 

if you stick a bigger injector without changing the constant it will not drip..It will still spray.

 

Ok seem's my explainasion has confused even you, that means theres no way he'll get it, lol

So I'll try this again If he sticks them in without doing anything, its gunna flood the car with excessive fuel, if he turns them down to get the a/f ratio good then there gunna drip AKA no atomization

Easier to understand now, then what I had before?

 

thank you for clarifying yourself

question, have you actually tried changing the constant value of a chip? Or you just read about these things?

 

I have 412ci motor running under a TPI, u tell me

I know far from everything though, still learning quirks and asknig alot of questions to milk everything i can.

But I try to help when it gets to something I do know

 

I didnt ask about your motor that greeny is doing for you..

 

Not sure what your trying to insinuate but I never said I could assemble a motor myself, but I did design it myself, and John (Greeny) asks my advice on cam's and heads and such all the time, he's a personal friend that knows how to assemble a dam good motor

I have also designed quite a few friends street motors around my area all running 13's and 12's, and yes Greeny is the one that assembled them

 

Oh and John doesnt have chip burning equipment of any kind, he's a carb fan rmember

 

Stupid thing wont let me edit, but the point was, a 412ci motor will not run all that good on a stock 305ci chip, seems you missed that point

Now I remember why I normaly dont bother to help anyone on here

 

the reason I ask is that analogy of yours is weird IMO. I was just curious anyway.My question was never answered though

 

Yes actualy it was

so its a link..

didnt mean to hurt your feelings though.

 

transamice your best bet to get advice would be to sign up on one of the following forums and ask in the tech section, helps get away from the idiots on here.

They seem to get off on childish highschool game's and intensionaly try to push your botton's for no apparent reason

transamice,

watch for the experts here.Sometimes the advice that you get from here are not actual experiences just a passage that they read on some link.

 

I appreciate the replies, its all good.
I wont be going that route anyways, I could probably go with larger injectors later on, maby 24lbs. Im not thinking of going too crazy, I just had an option to get 33lbs from someone and thought I would ask if it would help.

 

Asuming you got a 350 then 24# injectors would work fine

 

Another spot to ask is in thirdgen's actual TPI tech section

https://www.thirdgen.org/forums/tpi/

That is actualy true on here, but there is alot of peeps on the TPI tech that do know what there talknig about and do have some good experience

 

Not an expert but I did do some injector upgrades and armed only with wishful thinking and good intentions found out the hard way (isn't that always the way?) to avoid stuff you don't know the intricate details about.

I installed 24s in an L98 they were mostly ok but the not ok stuff really started to bug me. In the end I had to

a) re tune the car (which I don't know much about) for the 24s
or
b) buy factory spec injectors

I opted for b) and also got a copy of tunercat and am reading everything I can from Moates and the DIY board.

If I was looking for extra power I wouldn't do it through injectors. Too many easier bolt ons available IMO.

I guess some car's react diferently, we put ford SVO 24# injectors in Tim's 1990 350 Iroc and they worked perfectly fine with no tuning, only mod's at the time were a few bolt on's

 

Yah I found out later there are alot better pieces on the market like SVOs.

This time around I got Bosche 22lb'ers. Back to stock hey I just want something that drives well...

By the way glad to hear your car is going to be back on the road again.

 

Thing about haveing the 24 lb SVO 's is . They are rated differently than the GM stuff. They flow more than a 24 lb Gm injector ( just stuff I read ...don't really know) I would reallllly recomend getting the constant changed if running ANY 24 lb injector
