Which Injectors should i get?

[Preluder77]

OK im going to get new injectors because ours are pissing all over the manifold. Turbo tweak has 42lb with the chip for a good price. My question is will the 42lb be good enough for low 14s to mid 13s or should i go bigger?

"Pissing"???

Try replacing the o'rings, before you start changing injectors.
Your stockers will get you further in your ET goals, thanyou may think. Certainly, better than 14's...

it is the o rings that are leaking.. but the car sat for a while and had some really bad gas in it and still has a small hard start problem which i believe is the injectors everything else seems fine. So e figured rather than guess with that and since we will have the injectors out we mine as well upgrade. So if the stockers will get me better than 14s the 42lbs should be good right ?

just get the high z 60's that fullthrottlespeed.com has for sale and be done with it. never have to upgrade again if you plan to do future mods. and with the chips available today they can burn a chip no problem.

 

[Preluder77]

Not alot of mods right now. Will these still be ok for now? 60 seems really big

If it stays a hotair setup. You'll not make enuf HP to need a 60# inj...

 

[Boost231]

that is true thus you will never need to upgrade again.

 

[Boost231]

if you dont want to go that big get the 50's

running the Mototron 60# in a damn stock hot air car with a TT chip .. works and drives awesome...

The MotoTron 60's seem to handle small pulse widths well, and therefore probably work on even a stock turbo car well - provided you have the right chip.

I would go with 50's atleast. make sure they are flow matched

 

[Boost231]

see now i have more people saying go with the 60's. i wouldnt lie to you thats what i would do. after almost 11 years of working on hotairs i wish the 60's where out when i started. now i have gone from stock to 40's to 55's and if i have to upgrade again im going bigger. you dont want to go threw all that just get the 60's and be done with it.

Chuck is one man that knows what he is talking about. Stock injectors will take you deep into the high 12's- low 13's in hot air trim with plenty of fuel left over. Get the new o rings clean the injectors and run it. It all depends on your goals spend money where it is needed and don't waste it where it is not.

Yes, but if your not making big hp why go so big on fuel.

55lbers (57's) - 60's was a waste, not worth the cost for the minimal amount of extra fuel. You would have never have maxed the 55's especially with the added fuel from alky. (always looking for the next biggest craze)

42 lbers are good to 11.50's without alky I dought it.

Not trying to flame anyone just trying to clear the air for the new guys.

i have not maxed out my 55's but i did max out my 40's thats why i need to step up to a bigger injector. if he is planning on doing injectors why not do it right the first time. Yes he can tune tune tune and get his car running awsome with stock injectors then put a bigger turbo on it tune tune tune then come to realize his injectors are to small. then he changes out injectors and has to start tunning all over again. thats why i say go with the 60's. there high z and you will never need to upgrade them again. but hell if you want go threw several sets like me thats cool to. I would like to know why its so bad going to a injector that you will never max out? is it hurting anything? NO its not.

Hey Chuck! Long time no see man...hell,I think the last time we bumped into each other it was on moparts... .

Anyway as far as injectors go my car went damn near 115mph on 42.5s and I have PLENTY of injector left.My vote goes to the good deal on 42s it's probably more than you'll ever need.Especially if you add alky injection(which you should )

I agree that gross over-injectoring seems to be the new trend...

For what you're asking if you dont' ever really plan to race it per say or go all out 42 # injectors are a great injector for the street. You'll have plenty of injector to get you into the low 12's high 11's. If you plan to do more I'd recommend the 60# injectors. Then like previously stated by a hot air owner you're covered. It's really your preference. As far as running out of injector 42's werent' enough once I started to get mid 11's I was running out of injector. My car likes fuel and it's properly tuned. I jumped to a larger injector and wished we had done that right from the onset. My duty cycle went from being over maxed to only 40%.

Hey Jamie,do you remember what MPH you were running when your 42's maxed out?

What are you running for fuel pressure?

Timing/octane?

Just trying to figure why my car doesn't seem to need as much fuel...
