Peter'O'Nell would you please be able to post a dyno graph?

I'm refering to stao's test car result in dynosheet section:

http://www.skylinesaustralia.com/forums/index.php?showtopic=55845&view=findpost&p=5988137

compare to the best 2835 pump 98 result based on the same dyno

http://www.skylinesaustralia.com/forums/index.php?showtopic=55845&view=findpost&p=4972815

the 2835 also had set of cam gears which stao's are stock.

Will finalise mine before end year.

[LANDSCRIBBLE]

Its just i havent seen anyone with that turbo come close to Stao's results. Its the same with the current SS2, ATR43G3 FNT, noone can seem to match Stao's graph's. Someone please correct me with a dyno sheet of their own car with one of Stao's current turbos.

G3 FNT:

On the same time I don't see another 2835 matching listed either.

The SS and FNT turbos are too new, not many been built. and most of them are not running at their full potentials. So give it abit more time, more results that are equivalent to control will shown.

That second one is running on e-flex mate.

They look remarkably similar rather one much better than the other. The exh cam gear might fatten it up a bit earlier but last time I checked Trent said it makes no difference on an RB25.

The 2835ProS costs more but comes with everything to bolt on exactly to the stock location (from dump, new intake, nuts, bolts etc) vs a turbo requiring some fabrication. Given the threads out with SAU'ers having issues with fitting Hypergear turbos it goes to show that some 'simple' fabrication to some is a lot more complicated and expensive for others. The guys that have had issues for several weeks/months probably wish the spent on the HKS unit (if they were still available) those that have had no problems are laughing all the way to the bank.

[methz]

go garrett u wont look back, or your gonna end up spending double your budget.

[Irwin123]

haha yeah, they are super expensive....

compared to the hyper gear ones, 1500 posted, oil feed, direct bolt on... no stuffing around with exhaust etc, plus cheap to rebuild!

i guess response would be nice, and 300rwkw also,but what would the most boost you can run safely with standard motor/manifolds?

Will it still roll on if its super responsive? i think it would be nice if it did,

petero'nell: what kind of power do you get with the ATR43ss1pu? at what boost? stock motor?

Cheers< Chris.

Guys correct me if I am wrong cause I am no expert, but am I the only one that notices that the HG units need more boost to make the same numbers as the 2835.

I'm not bagging the HG's, I had one for quite a while before I upgraded to the hks. It's just something I have noticed.

I appears the Joey, myself and others that are running the 2835 seem to be getting ~280 @ about 18-20psi (just generalizing/average) where the HG units seem to need 20-22 to get those figures.

Less boost less heat?? ?????

If you go hypergear, and you do it right, first go, you won't be disappointed.

I just finished another intake pipe for my car. Done it my self. Full 3" the whole way. As others have said, if you go hypergear, don't expect it to be bolt on. You need to modify things to fit, move things around, make things up. If you are willing to give it a go, you can do some, most of it by your self. These days most money goes into labor and time. I payed $15 for my first intake pipe parts. $15 for this one. Others can spend up to $400 getting one made. I'm not losing money, but I will be wasting time if my pipe doesn't work. I spent $700 on a tune, payed a little extra to have the cruical bits of my car looked over(like fueling setup for instance). Day after my fuel pump failed and threw out the tune and they wanted more money to fix it. They should have known because when I did pick up the car, they had to make some huge adjustments on my adjustable FPR just to get it stable and they even had some starting issues.

Save your money, then draw up a list of potential parts. I found my self buying turbo's and selling them off as was always changing my mind. I had 3 different garrett turbos with me but I knew if I went garrett it would have been longer that my car was off the road. Fitting the hypergear turbo got me(a DIY, all bolt on stuff already done). It was done in the morning and finished before I left for work at 3.

You could always just get a high flow. My old car would romp this one in terms of coming on to boost, but when on full song this one just goes and up top doesn't run out of juice.

Not true. Technically, for my turbo, I may see a spike to 21 - 22psi which should push it above 320rwkw then boost will taper down to 20psi.

Same turbo, running 10 - 11psi, I made 245rwkw. The turbo is still in its efficiency range so its not getting too hot at those levels.

[DVS JEZ]

Your turbo on 11 psi made 211kw. Post a pic of ur new intake pipe

[75coupe]

x3 for 2835 ProS...

the expense means nothing once you drive it, it performs great, no mucking around trying to make it put out the numbers

looks trick sounds boss...

/end

[zebra]

What is transient/part throttle response like though, not everyone spends all day at WOT,

I would bet my left nut the 2835 poo's all over the Hypergear stuff at normal street loads and rpm

[DaveO74]

I reckon the same Zebra, just didn't want to say it az it is an assumption because I haven't personally been in a car with an ss2 or g3. But I have been tips mine "feels" much better and quicker than similar setups running a HG.

As you said there is more to it than WOT comparisons.

[DVS JEZ]

2835 = full boost 3200rpm max 280kw so far.

(rounded up 3kw for u Dave, dont tell anyone )

[75coupe]

289rwkw for mine on full load.. rounded down 0.3

waiting on E85 though....

and to the OP, this whole 300rwkw thing that people want for a street car, its simply overkill, I reckon 270rwkw is a heap enough in rwd street setup

[scotty nm35]

I doubt you could pick the difference in top end, its much better having it more responsive imo.

Apparently 300atw just isnt enough anymore, I have a car here with a GT4094 and another coming to fit a gtx4508, both 2j's. Its just madness for the street. lol.

[DaveO74]

Agreed, unless you own a tyre factory.

[Irwin123]

sagerx8: regarding this

Same turbo, running 10 - 11psi, I made 245rwkw

Do you have the ATR43ss2?

this is the one i am leaning towards.

I also have been buying things and changing my setup, its been going on for too long now

The 2835s may be great all around, however this is still a budget build, for the price i have seen these turbos i could nearly have my car finished

i just want a nice car to drive on the street, reliable, power when you want it and if it rolls on it will be a plus

for around 1500 you can get a turbo, which bolts straight on. all i have left to get is some injectors and a tune, and a few parts to make an intake

however i do appreciate all the options, as i want to wait till after Christmas to do it i may, and probably will change my mind a few more times haha.

[75coupe]

245rwkw @ 11psi...???

I want to see the graph
