With an safc II or a NEO AFC 210-220 will be a reasonable target

Stan had 211rwkw with just an safc 2 on 11 psi of boost (this is correct stan???) Keep in mind it is an r34GTT Auto

Are you after pictures of the inside of the rear housing ? ie. of the turbine ?

yeah,,

eg...

hi guys,

ive been asked this a few times differences between safc and powerfc. they will both make very close to the same amount of power if both have been tuned correctly. but clearly the powerfc winds hands down if it has been tuned correctly and has a bulk of its load points tuned. if you have the IGN and INJ tuned in the low load / light load areas the car will feel much better to drive, response will be better and fuel economy better than safc + stock ecu.

the main difference is the powerfc will support more mods and if tuned correctly will feel like a new car to drive.

both are only as good as the tuner.

car 1 - rb25det with safc

car 2 - rb25det with powerfc

its not like car 2 is going to make twice the power as the ecu costs twice as much. it all comes down to tuning and how the car drives, average power is the key here. the engine should feel nice on throttle response (IGN timing), come on boost nice (IGN timing) and cuirse will with good economy (INJ tuning). i would expect the power difference to be 5 to 10rwkw at the most

also powerfc has the following advantages over safc

adjustable IDLE

configurable knock warning

configurable injector warning

configurable airflow meter warning

airflow meter change support

injector change support

complete ignition map control

complete fuel injection map control

no speed cut

no excess airflow cut

I would add that there comes a time when tuning with an SAFC where you want to lean it out a bit more. But you can't because that advances the ignition timing and it knocks. So you end up with richer than desirable A/F ratios and hence sacrifice power. Power that you could unleash with a Power FC by virtue of its independant control (mapping) of fuel and ignition.

:mellow: cheers :mellow:

Hmm damn i guess i gotta just drive the car more often. It take me about 3 weeks to reach 1,000 kms.

Weekend car only you see.

Hey Dan, just wondering if you got the exact turbo as Satanic has?

His one is customized for auto transmission. Exactly the same as mine because i also have auto tranny.

Do you have auto or manual Dan?

Yeah my car is an auto as well, same dealeo that Stan has.

I agree with Paul and SK, the SAFCs become a little bit redundant at higher levels of tuning as the ignition cannot be touched... those with the SITC, don't worry about my comment, you're very lucky to have that option :mellow:

As for my setup, the very last tune was done using all the basic modifications barr a full exhaust (cat back only). We hit 200rwkw at 10.5PSI, boost dropped off a bit at peak power due to something.

Did another power run with a full exhaust (split front/dump in 3", 3" hi-flow cat, centre resonator removed from cat-back), splitfire coilpacks, re-gapped plugs. No tuning was involved, just a straight power run and we got 217rwkw. Again there was the issue of the boost dropping off. Surprisingly (think someone knocked it), the run was done at 10psi instead of 11 so that may or may not mean something.

I have since wound the boost right down to 9psi as it is currently running VERY rich. SAFC will be coming out in a week or so, engine work will commence and next tune on the 22nd will be using a F-CON V PRO.

With that, I will be able to max this turbo out without dramas and hopefully get to 260-270rwkw (18-22psi)... that's if the gearbox doesn't blow up first :mellow:

Thanks

Stan

Dam you all. You all sound like old BiTChen grandmother. Just relax.

I belive that when you compare price versus gain, these turbos are great. I am going to be sorcing one soon myself, but from what i can see, if you have the bugdet go get HKS ect, and half of the cost is the name.

Anyway Slide. Did you get my PM i sent you. It was in regards to getting one of these for an R33 to get 250rwKw.

Saving money for some 550cc from Sard I think or if I'm gonna go absolutely stupid with the next turbo etc, I'll go for the 710cc I think.

Bass Junky in another thread said that the new injectors for the 350z are a direct drop in? Hope he's right.

So any one who believes that $1750 for a ball bearing high flow is better value for money is bitchin? :mellow:

Let me give you another example of why I never use plain bearing turbos, EVER.

Just before Xmas I was doing a suspension set up clinic for an aftermarket suspension manufacturer. There were quite a few guys there with turbo cars, an S14 being one of them. It had an off the shelf fairly new Garrett plain bearing GT25 for around 400 bhp (240 rwkw). About an hour into the day the alternator wiring died from the heat and shorted out. This killed the electrics and the engine simply stopped, instantly.

We towed it in, let it cool down till after lunch and I bodgied up the wiring so he could finish the day. Started it up and it wouldn’t make any boost, dead turbo due to the plain bearings seizing up from the heat soak and cooked oil trapped in the core. So the guy wasted $450 for his day and it cost him $600 to fix the turbo.

That makes his decision to buy a plain bearing turbo not so economical.

As I said in a previous post, it's your money, spend it how you like.

:mellow: cheers :mellow:

I have only seen a flow test on one set of standard 350Z injectors (300 cc's) and they flowed less than R34GTT injectors (370 cc's). They were more expensive as well.

Part numbers as follows;

JECS # 166005L700

Bosch # 166002Y915

:mellow: cheers :mellow:

That was my point. If you have the money, go for it. But for those who don't race, and simply want something that will put a grin on their face, evertime they step on the loud pedal, then this is a very good option.

Thats all. No offence to anyone.

I was referring to the aftermarket injectors for the 350z, sorry for not being more specific.

If you punch in the R34GTT into Nengun as your car, it will come up with a whole set of injectors that are larger than the Nismo 480cc. There is no mention of aftermarket fuel rails/collars being required so I believe they are "drop-in"

I'm just relying on information I've read, so there is every chance that I'm mistaken.

S

Yeah 350Z and R34 use the same injector size, thinking of maybe contacting APS as they have 500cc jobbies for the 350Z, but I'd be happy with anything ~440cc at the moment. The R34 is almost finished as far asI'm going with it, the 350Z/V35 TT is on the cards for next year.

If what Dan (and I) is saying is true then the potential is limitless :) Especially good since all the tuning shops are now focussing on 350z/v35 over in Japan.

New GTR is the next frontier... company lease car here I come :nyaanyaa:

Especially good since all the tuning shops are now focussing on 350z/v35 over in Japan.

dont know if i'd go that far little buddy. :nyaanyaa: unless we are talking about different japans'? last time i was there sure V35 and Z33 were growing in popularity, but they are still no where near being focussed on by all tuning shops. many places are still building lots of 34, 33, 32 demo cars and of course plenty of toyotas too.

We have received our shipment of cartridges for the T3 Highflows so for all the people that wanted them late last week they are ready to be made again.

Only brand new Garrett cores will be used now for all Highflows.

We hould also have results on a 300zx set of highflows very soon.

We use GTIR Compressor covers. fit larger compressor wheels and slightly larger but better flowing turbines aswell. :P

:) Aaron

Ummm no...

I have had quite a few worthwhile discussions with both Gary and Paul, who are both knowledgeable.

I am referring to the sheep...so re-read my post and build a bridge...

Don't turn a good thread into your own self promotion... :thumbsup:

Sorry to bring this up, but in the interests of my own self promotion I can't hold back.

Your quote was:

'P.S. No one should discount this product until proven otherwise, the KKR turbo's were mocked repeatedly, now they have partly proven themselves, some keyboard mechanics should shut the f**k up'

And this was in a location where preceeding it there were 3-4 pages of posts where there wereno bad comments written about these turbos, infact the only comments written which were not relating to the product being good were posts from paulr33 and SK discussing the merits of examining all your options (BB turbos etc) before making your choice.

So you could see how I misunderstood you as meaning they were the 'keyboard' mechanics discounting the product as, as far as I could see there was no other comments relating negatively to the product in anyway.

I apologise to everyone in this post for bringing this up here in this thread as it is off topic, I just wanted the chance to explain myself.

I'm sorry for any misunderstanding this may have caused between us Bobjones, my previous post obviously came out the wrong way, I wasn't trying to discount anything you had said at all, I was mearly trying to point out that there were healthy arguments on both sides about the issue of types of bearings used in turbos (Which from my own fault, as I posted above, misunderstood you to be refering to posts made by paul and gary)

Consider the bridge built and used. :banana:

How can you ensure that shite-loads of oil is able to go thru this turbo (so it doesnt fail), ie what exactly needs to be done? Worried about that factor!

Also, how long should the car idle prior to turn-off after a normal street drive?

cheers.

    • What blows me away, is watching some of the US guys, like Tony Angelo at Stay Tuned. LS1, buys a set of heads for $1200, drops a mild cam in, pulls all the electrics, drops a basic inlet manifold with a carb, MSD thing for spark, and roll it out to make 550hp.
    • God I love shiny engine parts 🥰 Are you looking for more horsetorques in the mid range? (Smaller cam) Or just more horsetorques every where? (Big heads and bigger revs) Assumption: they were not bought late night shopping on the interwebs after drinking too many beers, which is typically how I pull pins on things......🤣 The evolution of your car is coming along nicely, I sometimes wish I didn't get bored with my cars and keep flipping them, maybe the MX5 will be different  
    • I got the hazards working! Turned out it was disconnected! Indicator stock still isn’t working. I took the steering shroud off and there seems to be a third connection missing I see two small white connectors but they don’t fit the indicator switch unless they need a short lead to convert the connector type. Can someone point me in the direction of the wiring diagram for the indicator switch?   https://share.icloud.com/photos/0e8ReiFSLBVJsTPUKKfA_1IdQ  
    • All of your suspension bushes/bolts etc, should also only ever be tightened when the car is sitting with full weight too.   IE, jack it back up, shove a heap of stuff down so you can lower the wheels onto so the car is "on the ground" but you have room to get under it.   It's why when properly done, you should be able to remove the shock and spring, but the arms won't go to 100% droop. If you don't do the above, you'll destroy your bushes.
