PTE Injectors?

[daren_p]

I need to get some new injectors, I was looking at the FIC 750's, since I know alot of people run them and have had good results. I see that PTE makes a 780 injectors & it looks the same as FIC, except they are abit cheeper. Are they the same? if not who's running the PTE ones & what do you think of them?

pte is delphi. same as fic. delphi injectors suck. huge dead time. if you got aem, or something that can compensate for dead time,ok. if not, you should get something else. if you MUST have delphi's, get a chip with compensation for the whacked out dead time. also, the delphis are rated at much higher fuel pressure than the industry standard, which is 3 bar(43.5, about). i think they are rated at about 59 psi. lastly, even brand new delphi's have whacky flow rates. dont ask me how i know. oh, and the ones i had didnt fit well, they like hit the side of the cyl head. at 15 lbs, they(650's) flowed about as well as the stock 450's. hella knock, and 90+% duty cycles. replaced with denso's, knock gone, 18 lbs boost, injector duty cycle in the hi 60's, WAY better idle. bought brand new from fic, who couldnt care less, never responded to my inquires. they were sent out to be flowed, and they were way off.

i'm also nt happy with my FIC 650's. they seem to be very difficult to tune, and dnot seem to flow what they should just based upon people i know with similar setups to mine.

how about rc injectors?are they any good?

 

[daren_p]

Dead time won't be an issue for me as I will be using DSMLink. It seems alot of injector companies rate their injectors slightly higher then they actually flow. You said PTE is known for this? That would make sense since it looks like the FIC & PTE are the same but FIC has 750's & PTE are listed as 780's. What does everyone else think of these? I heard from a couple guys that had them & said they worked great (they were using dsmlink as well) What exactly are the Denso injectors? is that a brand name? I've also heard good things about these injectors but wasn't sure where to get them from. Every so often I see "Denso 660 injectors" listed on ebay (the pics have a blitz box in the background) are these what I should be looking for or are they a knock off?

I believe the RC 550's are great but I was told that their 750's aren't good because they don't idle very well.

Wow, you guys are getting way to technical for such basic setups. We've used FIC's, PTE's, and RC's. I've always had good luck w/ the PTE and FIC, its the RC's that have failed.

i was going to say the exact same thing.

 

[qtxdevilz]

ok...pte and fic are made by the same company...so what are the differences?i have read that one of the companies cut the ends of the injector differently and that they come with a different o-ring?

i am referring to my personal experience only. i expect BRAND NEW injectors to work properly out of the box. and if they dont, i expect the company i buy them from to stand behind them. i shouldnt have to send them out to get cleaned and flowed, and then find out they AINT flowing near what BRAND NEW injectors should be, and i shouldnt have to pay to have them cleaned and flowed. and, i expect at least a response to my emails/phone calls. i got the delphi's because supposedly the ball/disc type is superior to the single pintle. it is, but delphi's are made by rochester, not the sharpest knife in the drawer.
nippondenso is a huge japanese fuel injector manufacturer, the greddy 660's are made by nippondenso(dark blue tops). the denso(greddy) 660's have the same dead time as the stock 450's. i even had a 650 delphi chip in my ecu, and they still ran like crap. even with the delphi chip, the denso's worked WAY better. the only reason delphi's are so popular now is because they are cheap. and the bottom line(profit) is better than the denso's. think of it this way, you got a cheap motor, put in cheap injectors. you got a 50 dollar head, buy a 50 dollar motorcycle helmet.

Ahh... I have PTE 780's and they work perfectly fine. Yes with injectors this large you will need a chip to compensate for them. But there is absolutley nothing wrong with them. Very nice injectors. I would buy them again if I had to.

I have PTE 680's with dsmlink. Easy to tune but they flow more like 550's. My global is at -17% and the deadtime is 180. DSMlink has a "general" reference for what your global settings should be with various injectors. Check out page 16 of this:

I really wish I hadnt got the PTE injectors to be honest with you. Ill probably go bigger sometime soon.

Good luck

Hmmm, I was going to get a larger then I need injector right now, so I wouldn't have to upgrade if I get a larger turbo (currently running evoIII) So it looks like if I got FIC or PTE 750/780's they flow more like 650cc, which would be more then enough now but would that be big enough if I descide to go with a 50 trim?

 

[PSI2HI]

The FIC/PTE 750/780 flow plenty of fuel for well over 500whp. For a 50 trim there should be no way you need anything larger than a 650/680.

That should be fine for a 50 trim. I made a mistake in getting the 680's. Now I have an rs49 sitting in front of me along with a fmic. I will probably need to go bigger now...

If you have dsmlink or something that allows you to adjust deadtime, I would strongly suggest getting larger injectors. Going from 680's to 780's is only $10-30 more, so why not get them if you can tune them with dsmlink or equivalent.

I always screw myself in going to small...

 

[daren_p]

Sounds good, I'll go with the 750's or 780's, since I have dsmlink & controlling them is knot a problem. So now I've got one more question, if PTE & FIC are the same injector how come the FIC's are always around $40-$60 more a set compared to the PTE's?

 

[16g-95gsx]

I run PTE 880's without a hinch with DSMlink. If you have an issue with PTE overrating the injectors, which I dont believe to be true, then why not get a larger size than you want? If you have DSMLink 880's or 980's will flow like stock, so overrating wouldnt be an issue at all. As far as deadtime, I mean come on they are large injectors, there is going to be a deadtime increase.
