I raised the fuel preasure to 52psi, that puts the 550s to 610CC fuel flow level. I now have my AFC leaned out a lot more then before, actually it's at -26 through the powerband. It defenetly moved my AFC settings far from fuel cut, and my timming is much better do to the lower airflow numbers the ECU is seeing now.
Sorry to bring back an old thread nano, but do you happen to remember what boost levels you were running with this fuel set up with your pte 50 trim set up?

Reason I'm asking is that I just purchased an internally gated FP Green and I'm coming up from a FP ported Big28 as with you, and I'm still using 550's as well, but I do have a AFPR, just curious, thanks!
 
Yeah that was a while back. I remember that I didn't run more then 21psi on the 550s. Lowest I ran was 18 psi, but I'm pretty sure I was in the 19 to 20psi range. I actually didn't like it too much since the ECU kept trying to run 18 degrees of timing. I should have been running more like 14 degrees after looking at my knock with DSMlink. Just run it a little rich.

Hey thanks bro I really appreciate it. As of late, I was kinda following in your foot steps somewhat by running a Big28, cams, and a 75 zex wet shot and the car is extrememly strong with that set up, but I can't wait to get this green on to see what it can do. Thanks again for the help, and or info. :)
 
I'm just curious as to where some of you guys are tapping in at for a boost source for your boost controller, especially those that are running internally gated Greens, and other internally gated 50 trim variant type turbos?

When I ordered mine from FP they didn't put a nipple on the compressor housing like I had on my FP BIG28, so I have mine tapped into the BOV line, and the other line into the wastegate actuator.

For some reason I'm only able to run about 11lbs of boost on my Green even with the boost controller all the way maxed out.

Do you guys think I should shorten the wastegate actuator arm some or do you think there is something else wrong somewhere, because I don't even hear my Greddy Type-S blow off anymore?

Thanks for any help!! :)

They give you an adjustable wastegate actuator for a reason. ;)

I at one time ran mine internally gated but have since gated it externally. Has run 121mph on pump though.
Sounds good and promising bro! :)

Do you remember by any chance where you tapped in for a boost source?

I have mine tapped in on the bov line, and the other end to the actuator, but some people tell me not to tap into the bov line, and FP tells me it's OK to do so. :confused:
 
Haha that is my post and my turbo.

I'm not done with install yet though, oil feed leaks :|

Anyway, it's probably that if you do run it off bov line that it does open early. Depending on how much though influences your perceived effect that it has.

only way to really know is to use a different source and see if you can raise the boost.

Hee! Hee! yeah I don't mean to hijack your thread over there bro. I just didn't see any reason to start another one since you were basically on the same subject as me. :)

Anyways.... today I still left the boost controller tapped into the bov line, but since I was only seeing about 11lbs of boost, I decided to shorten the actuator arm down to where I could only see about 4 threads showing on it, and I'm still only running about 15lbs, where as IMO I should be seeing around 25 plus pounds of boost by shortening it that much. My boost controller does not work at all. I have tried to turn everyway that I possibly can, and it does nothing.

I guess maybe tomorrow I will drill and tap my lower IC pipe and try it there for another boost source, since my turbo is already installed. I will probably steal the nipple off of my old FP BIG28 and use it. I also have a dead EGT probe, and now my upstream 02 sensor isn't registering at all for some damn reason. It's not registering on my S-AFC or my logger, so I don't know if that might have anything to do with it either, the 02 sensor that is.

Sounds like you may need to use a little thread sealent on your oil leak that you have. I used some permatex thread sealer from Autozone on mine, and so far I haven't had any leaks other than what I forgot to tighten up.
 
For a while I thought I was insane to drill into my new turbo but eh, even though it's brand new there isn't really a warranty on it anyway.

Basically the extent of my ability is to bolt stuff up and maybe cut a little bit. I knew that tapping bov for wastegate was bad but the piping on my jpipe was also way too thin to securely hold a nipple. It would have had to have been welded.

It's a little difficult reaching in to tighen up the oil feed line since it's in between the comp and turbine housing. I am also a little concerned about thread sealant/teflon tape since i've read about turbo failures from having the passages clogged. I think that's what I may have to do though

Well... I would try to drill my turbo if I hadn't already installed it two times. I really can't get a drill down in there at the angle that I need to do it anyways, and trust me that thing isn't coming off again.

I had to take it right back off just because I forgot to tighten up the fitting that goes to the banjo bolt for the oil feed line, that goes to the turbo.

So... I guess I will tap my lower IC pipe tomorrow and see how that works for a boost source, and then try and find me a reasonably priced 02 sensor somewhere and install it.

As for the teflon tape, I would'nt use it. I would rather use thread sealant. You really don't have to go over board with it either, and you don't have to coat it all over it either.

I went by what the instructions said and I skipped the first thread, and then put a bead around a few of the threads after the first thread, and I made sure to wipe off any access, and all is well now. I was stressed a little about it though, but it came out just fine. :)
