Must be dud fuel and tune is close to the edge so very little difference made it ping

If 100 octane e10 made it not ping

[jet_r31]

I think its not a bad result for a auto considering its usually 20kws behind a manual box. What does a locked convert do? I'm thinking of working out my Kia's auto.

its not a bad result, before we used wmi, it made 258rwkw, and at that time they said they have done 5 3076 56T .82 setups

on stageas and that the good ones got into the 250's on same boost and all 5 where out of puff the same, even the ones they owned personally... i woudn't run that timing though, id pull 2 degrees out if it was a 98 tune, and it was on the knife edge

In all truth, the wmi let me run 12 degrees more timing when you take that into account...lol

..theres a few thing i can check, and a few things that happened that i'll keep to myself and see if the theorys workout,I'll revisit the dyno in a month or so one night.

Im happy with the turbo and everything, just want to make sure its all working as well as it can

out of interest stao, is there anything you can build into a T25G exhaust housing?

cheers

[hypergear]

Yes the atr28g4 is a of a .64 ended t25 turbine housing and that makes 300rwkws on a ca18det. Just abit laggy.

[4bidn1]

converter locked, not letting cool down really, 2 massive transcoolers, one has a thermo, total overkill..lol

yeh its fast,it would be deceptively quick but even my mates vl that runs 10.3@133 doesn't feel quick to me either, thats linear to in its delivery

my mates brother has a car that we use for a guidepost..R34 270rwkw on 17-18psi, 12.00@117mph. ill see how it goes against that, my mates 338rwkw stagea flogs it

cheers

Hey Daz was actually looking at that r34s dyno sheet when we got back from the dynoing your stag, it has a very progressive curve makes 281rwkw on 21 psi . It's also more sluggish in spool than yours .

haha..my bad, thats a huge bitch. And i wasn't thinking. I meant to say a Ca18 T25 housing, the .48 ones

Something that would fit in that housing, but give greater flow than standard turbo and good response still

for a 1.5L non crossflow motor on 20-25psi..talking 150-170rwkw. i guess.

Be good if it could still bolt in a .64 housing later for testing purposes

Something that would make 210rwkw ish on a sr20 on 98 with best response may be in the ballpark ish

even a standard Sr20 T28 would be decent, just wondered if you had something better..

Probably the 64mm billet SS1 in a CA T25 turbine housing should be some thing nice for doing that.

[GTScotT]

Darren just put a T28 on it and it will do well.

[hy_rpm]

Just installed my hiflow atr28g2 with new .64 rear housing and fnt mod on my sr20det

Feels more responsive already untuned than my td05h18g and its only on 1bar for now till I get it tuned in a few weeks

Giving it 3/4 throttle comes on quite smoothly from 3500rpm on where as my previous turbo had nothing till after 4000rpm also has a slight whistle to it as it boosting up from 2000rpm on.

Is this normal as it has fnt ?

Sound very similar to the semi trailer trucks

Hoping its makes similar power that I had before but better response previously had 264rwkw with a td05g18g 24psi dropping to 21psi by 4000rpm on eflex

I'm going to run 22psi response wise I can feel its definately going to be better just hoping it makes the power

[hypergear]

Could be induction sound？Just make sure it has plenty of clean oil supply and none restrictive oil feeding line, it should be fine. Make sure it has 3inch free flow induction and exhaust before going to the dyno. Preload actuator as you go if more boost is required.

Darren just buy my HKS 2535.no more lag than a 2530. And on a ca18det would be crazy fun alround. Comes with dump oil water lines. $950ono. .64 rear. I had one on my s13 ca18det 8-9 years ago and was mental fun. Done 15,000km in 5-6yrs, bought néw from created in Melbourne. Just a thought. Perfect condition. Come off my r33. It's still on there matter a fact. Could even put it in the .48 housing as you mentioned above and sell the HKS rear. ???

But I'd leave .64 cos.48 would choke it wouldn't it Darren ?? Anyway just a offer mate. Sorry to pinch the thread.

Cheers Josh.

used a t28 before and a hks 2530. But yeh a standard style T28 modified to fit a .48 housing would be around the

mark in my eyes

lol, its not for a ca18, and i have used a hks 2530 on these motors 12ish yrs ago..was just wondering what stao had. its not for me, i just sold a mint 2530 for $600 last month as i had it sitting in a box for 7 yrs

Also depending on the compression ratio of the motor its going to fit. For a modern 10.5 : 1 motor, a slightly larger turbine end is helpful on stopping it from pining on higher boost level. Like a 1.5L engine on that sort of compression ratio should be pretty responsive with a .64 turbine end with a 68mm compressor if the goal is about 24psi.

[jet_r31]

no stao, 8.5.1 comp, 2 valve , non crossflow, poor flowing head toyota k motor head.

can you fit a larger turbine than standard T28 spec stuff in the .48 T25 housing out of interest?

cheers

darren

[GTScotT]

Lol @ Toyota K series. Come on daz just 4A the poor thing and put it out of its misery.

[jet_r31]

lol, its not me, was just asking for someone and out of general interest, as Stao might have something in his

bag of tricks i went 4A a long time ago,(although i havn't finished it..ffs)

yes I have made couple of turbine wheels that goes into the T28's bearing housings. This is mine personal CA18det turbocharger out of my Sil180 few years ago. I've made this after been defected to pass EPA with (it worked). lol

It has a small 52 76mm comp wheel with a massive 65mm turbine.
