hey guys looks like we may have another source for injectors. If you go to google, look under modified injectors wrx. You will see the wrx guys are using modified nissan injectors. Also at perrin they are modding injectors for the wrx's for cheap. I wonder if they would mod nissan injectors? Here is another source to look into. Let me know what you think.

have you ever heard of reading the stickies at the top of the page especially the one about injectors

 

I've talked to Perrin about their injector modification option. They can only modify the 2004 STI injectors and they do not flow test them. He really didn't want to talk about injector flow variability after flow testing. He just said he didn't think it was an issue. From my experience, it is a big issue.

 

I saw the stickies at the top of the page, but the only thing i did not like is they were used injectors. I have seen plenty of injectors fail, while working at the dealer. The problem is if an injector fails at wide open throttle on boost you will cook that cylinder. Everyone should be checking the resistance on their injectors from time to time. When it gets excessive replace it. It may save you a motor.

 

Call me stupid but if a injector all out fails.. no fuel comes out.. no bang in the cyl.. no melt down. It's prity much impossible to melt somthing with no fire. If it's the only one "clogged" or somthing only spraying out a 1/3 of the fuel yea.. we got a problem but I can't see one not working at all and causing engine damage.
Thanks for all the advice in the e-mail you never sent me turboquack.

 

i was thinking the same thing i wouldnt understand how a cylinder could detonate with no fuel at all and i have had 1 injector fail on me and the car just lost performance with no side effects

 

It's the chemical reaction of the fuel in the cyl that cools the cyl down. I did not specify what type of failure. I also don't think most people would want to take that kind of chance with their motors. I suppose in your motor compressed air don't = heat. So go ahead and take the chance. You see i am usually very private about my set up. Just because you read something does not make it true. I was on the internet talking about my results and failures. Now i have a bunch of skeptics that don't sound like they know much about cars trying to discredit every post i make. You see i didn't have a digital camera thats why i never posted pics. Even the pics you have see were not posted by me. Someone put those up without my ok. I would have talked to you on the phone, and went through your set up with you step by step. Would have been easier than posting back and forth. But insted you choose to ridicule what you have not yet seen. What is so unbelivable about 16psi on pump gas and 25 on race gas with 370cc injectors with stock internals. There is allways a way to push the limit and i have. It's actually not a big deal to me anymore, cars been like this for a while now. So now i will post pics, and a live dyno, and live 16psi run. Later i will post a 25psi dyno run and this summer 30psi. I will also not be helping anyone who has mocked me.

yeah i said it!

 

Well, your idiocy has been confirmed. Cars turn off their injectors whenever you let off the gas at speed(coasting). If you haven't noticed your engine doesn't explode every time that happens. You probably have noticed a little waver as the engine speed falls below a certain rpm and the computer turns the injectors back on to keep the engine running. New engines like Hemis shut off one bank of injectors all the time to improve fuel efficiency. Compressing a bit of air 10:1 isn't enough to cause any form of detonation or any damage to the engine. Excess fuel will keep temperatures down but that's b/c it's preventing proper burn.

Your understanding of thermodynamic reactions and injector technology in general is quite simply ignorant and no one is willing to believe you b/c nothing you say is believable. The fear of undersized injectors at the limits are lean conditions which cause detonation/explosive cylinder pressure not sudden injector failure and the cylinder cooking off b/c there's nothing but air.

While race gas is able to reduce detonation by allowing for higher pressures before exploding uncontrollably...the horrendously lean condition you must see at 26psi and grossly undersized injectors would quickly destroy your stock engine. We're nearing max duty cycle on our 370's at 7psi according to our e-manage and the upper limit even w/ upped fuel pressure is ~10 psi safely.

Do yourself a favor and enter your setup into a fuel injector calculator and you'll understand that your current injector size even running past 100% locked open would not support the boost/hp levels you're claiming.

Wow, I didn't realize that a combustion reaction has somehow gone from exothermic to endothermic.


How ironic to hear this coming from you.


I pray for the poor soul who gets "help" from you.



You are an idiot.

 

 

In referance to that thread, all injectors are soncially cleaned, flow tested, and new seals put on. Can't get any safer than that.

 

since the injectors that supedave2 sells have been sonically cleaned, they are as good as new. they flow match as close as possible and are a great seller. the only reason that i have not gone with their injector is because it is a little large for my setup. i cant wait until we get mike's setup running with those injectors and will put quake to shame.

 

Now, I am saying it.... your post was down right stupid. I am not the smartest person here, but you might be the dumbest.

Anything I see you post that is not a dyno, dyno vids, in car vids, proof that you own a maxima,etc... will be locked or deleted.

And on USED injectors.. YOUR 100% correct. Used injectors may be bad. HOWEVER, when the person selling them has them flow tested and cleaned, they are as good as new.

MORE proof that you talk out of your a$$ more than your mouth
