I don't have a good picture of it on my car, so here is one of my old turbo altima

It's just nice as it keeps things tidy in the engine bay. Certainly not as cool looking as an aftermarket (persay Aeromotive or JG or similar) but it's ability to just mount and work really appeals to me.

That's REALLY interesting to see! Only thing that would concern me would be 'room' in the engine bay. Look like she'll be a tight fit, but the V band 44 gates are nice becuase you can position it anywhere.

Yeha i have an aeromotive, but the thing is massive. Its very big and I have to run additional lines and all this junk.... Sigh....

That's the only PITA for me. Silly gripe I know, but i like simple things.

I now run an AEROMOTIVE 13105 unit, it's not that big stop using your penis size for reference!

I inherited mine from a friend. Its one of those 3 port ones so I can install an on regulator gauge... Where did you mount yours? can I get a picture?

See that's what I don't get...the regulator mounts after the fuel injectors..so would you want hte gauge before or after? Would it make any difference? I mean I'd think that the FPR mounted gauge (like Aeromotive) would ive you 'end of the fuel rail' pressure, where one mounted before would give you before rail...but what is really best? I've never really 'worried' about this (i mean so many have them mounted pre rail, inluding myself) but I'd think it's not ideal.

Thoughts?

comparison shot the HTC Hermes is putting in work!

Code:

 This is really a temp install, because I knew it was going to snow soon!

I've taken pressure reading from the regulator and before the rail, they are the same. Atleast for right now! That's why I've chosen to mount the sensor on the regulator.

That little whore....! there she goes again!

and for you guys that wanted to know what the Special T25 EWG .72 a/r housing looked like in a real picture here it is!!!!!! side by side with the .64 and my GT3071 vs. GT2871 compressor housing for more flow. im shooting for 430+whp give or take. more details on my set up later but this is the sneak preview lol

If you go external waste gate let me know. I'll buy your actuator off of you

I have the big aeromotive (left side of pic on strut tower), mounts easily and works great.

Dude great setup... I have my ignitor mounted there.... You know whats most awesome about your setup??!!?! Cold pipe BOV. Freaking awesome...

Dude what ABS system is that?

Why are you impressed by a bov mounted on the cold pipe? The stock bov is mounted on the cold pipe on s14/s15 sr20det engines.

And its a s15 so the ABS components look a little different.

Csomme · 12-30-2009, 08:58 AM

Quick question guys. Can anyone post injector and ignition maps for their tune with their setups on the power FC?

The reason I ask is because my injector duty cycles are at 100%, and it's detonating like a mofo in boost. I'm just trying to be a dick and steal someones tune untill febuary when I can get it professionally tuned.

I bought the car and was told it was professionally tuned, but DAMN this tune sucks.

I'm running gt2871r, hks 256 cams, greaddy intake manifold, 550s, etc.

If not, thanks anyways guys. Just thought I'd ask.

Contact Steve Shadows, he can send them to you and probably has a map for a setup like that already....

Most people have it on the hotpipe not the coldpipe. Its better for relieving boost pressure than on the hotpipe. Even though people have s14 or s15 swaps.

Still that is a nice RHD S15.... Track only?

Csomme · 12-30-2009, 11:17 AM

ALRIGHTY then. Sent Steve a PM. Hopefully he's able to help me out.

The car was supposedly professionally tuned. lol.

How so? I would figure you want it nearest your turbocharger to prevent surge?

Compressor Surge I believe comes from reverse pressure flowing back into the turbo. This is cause when the throttle plate is closed, so the area of highest pressure flowing back through the system is at the cold pipe more correctly right in front of the throttle plate.

Correct me if I am wrong

steve shadows · 12-30-2009, 05:45 PM

Yes,

If any of you guys need your maps looked over or a new base map for your new turbo upgrade dont hesitate to hit me up.

My discounted rates will be ending at midnight on Dec 31st however, So if you are thinking about getting a map or will be needing one in Jan, you can send payment before Jan 1st and come back later in Jan for the actual map once you are sure you have the setup you are gonig to be using or I can send you a map for your setup and you can just save it until you get your EMS in 2010. My support for the map is good for up to 1 year after you order up your base map or remote tune.

See that's exactly how I understand it as well, but I would assume that being it's the turbo itself 'creating' the compressed air, that you'd want to vent it as near as the source as you can (much like how anti surge housings are done on the inlet). Either way, I'm not suare either, but would love to know 'proper' setups ya know?

I guess ultimately it shouldn't make much a difference so long as there is one. I think another 'ultimate' factor also boils down to 'placement' and the sort. For me, the hotpipe works perfect as for recirculate it's only a 4" distance to the intake

idahotuner · 01-01-2010, 10:55 PM

i would think that if your venting to the atmosphere that near the throttle plate would be best to keep the air from changing direction. close your throttle plate opens another path right next to it. but that being said i really dont think it matters. as long as you run one that is funtional

slider2828 · 01-02-2010, 12:23 AM

I sometimes don't really want the pressure to surge back through the intercooler setup. Yeah I think the point of highest impact when that plate closes is at the throttle body. Like that guy said, on stock S14 and S15 its on the cold pipe side....

S13 curtis · 01-05-2010, 12:04 AM

how high can the fuel pressure be set with this nismo FPR?

There a couple od schools of thought on this:

Firstly - placing the bov on the cold side means its closer to the vacuum signal and therefore the vacuum line is shorter ...making the bov more responsive to a closed throttle position.

Secondly - placing the BOV at the closest point to the throttle plate means the momentum of the air post the turbo and through the intercooler /piping system is not disturbed until the latest point.....at which point when the throttle plate is reopened the momentum repressurise the plenum at a faster rate as it doesn't require the turbo to repressurise the entire intercooler system in the case where the bov is located on the hot side.

2fast4y0u · 01-05-2010, 05:49 AM

my uncle is the crew chief for the worlds fastest drag radial car...car has set and broken its own records for awhile now.
last time he was up here visiting he saw my car and just look at me like WTF!?!?!
he asked me why the hell my BOV was on the hotside so close to the turbo and why i had vacuum lines all over the place.
i told him thats how the piping was made and i just put it where i was told...so sense then i have purchased a cold pipe with BOV flange on it because he said its retarded to run one on the hot side...i would take his word for it..one of the cars he watches over runs twin 90 trim turbos with twin 60mm wastegates. 5 1/2 inch charge pipes and 6 inch exhaust.
i know hw is on a COMPLETELY different level then us, but everything he has told/showed me on my car has made it run amazing!

Guys are running it on 4 bar base setups with 20 psi (60ish+20=80) so I'd assume it could probably handle 100 psi of fuel. Don't quote me on it though.

Hehe I re read my corkey bell book and he said the exact same thing. I've read maximum boost countless times, but seemingly forget such basic stuff haha. Good to know!

The only thing that would now concern me, is the long length of recirculation pipe/tube required if running it on the cold side, and recirculating it to the intake tract.

slider2828 · 01-05-2010, 09:48 AM

I would love to recirc too, but I for one never had any idle problems not recirculating..... maybe cause i am MAP based? no idea...
