PTE 680cc Injectors??

[TTA89]

Is there a certain number located on PTE's 680cc injectors to verify that they are 680cc? My friend ordered a set from Ebay & he is wanting to make sure that they verify to be 680cc injectors before he puts them in.

Thanks

 

[prostreetdsmx1]

just food for thought....

PTE does not back any product purchased on ebay.

Aside from that, each set of PTE injectors comes with a flow sheet saying what they are and i just checked the different sizes i have hear and there isnt anything showing specific ID info on the injector itself.

 

[TTA89]

Thanks for the fast responce. He did mention it came with the flow sheet saying 680cc @ 43.5lbs of fuel psi @ 80% duty cycle.

he should be allright.

he'll know when he installs them.

Mine also came in individual bubble wrap bags that had 680 written on them.

 

[prostreetdsmx1]

yeah thats how they all come.

 

[anconover]

mine came crammed together in bubblewrap bag, my friends came in seperate, both had totally diff numbers all over them. sometimes ive seen them have 680cc etched in the side of em, sometimes not hehe. Once theyre in youll know, shouldnt have a problem with em.

I got a set of 880's off ebay and sold my old 680's, they were exactly what theyre suppose to be.

I ordered mine from dejon tool to be on the safe side, and I got the same as everyone else. Also, slowboy claims that they are selling injector clinic injectors, and they are identical to the ones I got - w/ the same meaningless numbers etched on the inj. body. I ordered 680's - and run my maft at the 680 setting, and I've had great results, at the track and driveability.

I believe dejon's are Precision Turbo's. I have a set fom him also. Mark

We sell Fuel Injector Clinic Injectors.

Only time i buy PTE injectors is when i need 1000 cc injectors or something for a grand national

Just putting this on for clarification.

the injectors have numbers on the top of them. call pte and give those numbers to them and they can verify the size for you.

The only differnece in FIC and PTE injectors is the way they machine the lower part to fit the head. The FIC are unmodified on the bottom and they found some crappy rubber piece that halfway fits the head. The PTEs are actually machined down and have a nice little plastic tip to mimic the size of the stock injector so you can use a set of brand new, proper fitting stock lower seals. Why do you think the FICs are cheaper? You get what you pay for, less work and more rigging to make fit.

The injectors will have a # written in small gray boxy text. Post that # here and I will look at our injector sheet and verify which ones they are tomorrow.

We have sold 1000's of FIC injectors with no fitment issues or leaking what so ever. We could buy PTE's cheaper than FIC, however FIC have always worked great for us, and Frank is one heck of a nice guy

I thought that PTEs and FICs were made by the same manufacturer. Is that not the case?

ummmmmm, look two posts above yours.

Ummm, I saw that but it doesn't answer the question. Just because two things are alike doesn't mean they come from the same factory. Especially when Mike's post seemed to imply that they may be different somehow.

They start out being the exact same injector. PTE modifies the bottom of the injector by machining it down and adding a plastic sleeve "that is easily replacable btw" so that they fit perfectly into an OEM lower injector seal. The FICs are unmodified at the bottom and they sourced some kind of seal that works. It does just that, work. Every time I've had to deal with one, it makes instalation and fitment that much more of a pain in the ass over the PTEs. Either way you go, theyre still a hell of a deal compared to Denso style or RC style injectors.

We even go as far as to include a brand new set of OEM lower seals every time we sell a set of injectors. There's nothing that makes you madder than getting ready to throw your new injectors in and finding out your 12 yr old lower seals are cracked up worse than Marion Barry and sucking more air than George Bush trying to BS his way thru an open question forum.

 

[sweet97]

I've used RC's and PTE's, both nice. Nowi have a set from Buschur racingthat i always thought were Denso's.Howcan i tell? There is what looks like an RP script near theelectrical clip on the top. HELP! Mark

 

[Maestr0]

So do the fic injectors come with the seal already installed on the bottom?

 

[daren_p]

I have FIC's and they come with the all the seals/orings your need. Yes FIC's & PTE's come from the same spot. I went with the FIC's because the seal they use is supposed to be better then the factory ones that tend to dry out all the time. Also PTE's are more expensive then FIC's? Every place I checked it was the other way around, but I paid the extra for the FIC's because I heard better things about them compared to the PTE's which are also rated at a higher pressure then the industry standard of 43, ie their 780's flow less then the FIC 750's.

This is confusing since it was mentioned earlier that FICs and PTEs are made at the same factory and PTE machines the nozzle to fit the stock seals. If PTE 680s come from the same place that FIC 650s, then PTE "re-flows" them at their place at a higher than standard psi and then sells them? I have PTEs from Dejon Tool and they were tested in their car and supposed to have matched a 650 cc adjustment made to their maf translator but they are definately less than 650 on my translator. I can see PTE selling 650s as 680s if they use 47.5 psi as a base pressure. But i was told by guys who emailed PTE about the issure that PTE said that they use 43.5 as base.

All this confusion leads my to believe that it is really an issue w/ injector deadtime... PTEs have way more dead time the stockers or denso like 2-3 micro-seconds. This has been confirmed with my dsmlink. This also explains why i had some wacky settings with my maft. but when i zeroed it out and used dsmlink to tune deadtime and flow everything went to the "correct" correction factors.

This is confusing bein that they are made by the same company, maybe their made in different locations? Ive just heard many times that PTE's don't flow near what they are supposed to, this could also verify that they are tested from the factory at a higher pressure. But you would think that even if the PTE's are slightly overrated (according to standard pressure) that their 780's will flow the same as FIC's 750's but I've heard otherwise & the manual that comes with dsmlink has some base settings that alot of guys have found to be good & it too lists the PTE 780's with less of a correction factor compared to the FIC 750's, which should be opposite if they are rated the same way.

 

[dsm-onster]

You know looking back at the manual, that's true. PTE 680s need to be corrected to -29% which comes to around 634cc. FIC 650s need to be corrected to -31% which comes to around 650cc. Nevertheless, i was able to dial them in correctly w/ dsmlink and i havn't had any trouble with them since.

It seams that the more expensive injectors have less deeadtime (you get what you pay for). My suggestion is if you're going to get a cheaper fuel control setup (SAFC, MAFt) you'll need more expensive injectors to dial them in correctly.

 

[doug]

I have my PTE 780s set to -39%, which is right about what it should be for 750s, and my fuel trims are right on. I'm using a dead time of 270.

 

[vr4play]

For those running the MAFT setup, what size injectors are you running and what is your MAFT setting? I am running PTE 680s, and I am set at 750 on the MAFT.
