Interesting Dyno Test On New Hypergear Turbo.

[DRD-00F]

Indeed I do...

I will still accept free items though

Is that the HyperTune in Spring valve? Owner's name's Yin?

Just can't help reading this thread over and over again. Making 260rwkws at 5000RPM on a CA this is just insane. Even SR20s on GT2871Rs can't even do that as in both response and power. really good work guys can't wait to see what can it do on my RB25.

ask and ye shall recieve

[Cartman]

so this is the same turbo as wat they are offering into standard housings for the bolt on rb turbo in the other thread?

and yes.. thats insane power and response for a ca18

S15 with GT2871R 56t (stock bootom end)

vs CA18det with hypergear turbo.

[Adriano]

Boost levels?

URAS - how much are the cams in the CA helping with this figure?

The more I read about CA's the more I want to try one as the next car.

I'm curious to know if this $900 ATR28 turbo is available as a bolt on to an RB20 and if so, what would it make.

[hypergear]

^^^^^

They are cheap re-grinded cams: 256/8.9 . I got done 3 years ago at wade which costed me $120 in total for 2x. I guess they didn't even know what a CA18 is back then. You can use Tomei Pon cams which will give better result.

ATR28 G3 will be available next year as in a direct bolt on form we are doing our modeling at moment. This CHAR is highflowable into Stock R3x Turbine housing. by calculation it should give similar result with lot faster response. We will make one for evaluation and should have the results by new year. But drop in an email if you are interested in evaluation.

good comparison. the CA makes a fair bit more power but the SR would definitely be punchier on the street. at 3500rpm the SR has 110kw vs 60 for the CA. and at 4000rpm it's 165kw vs 100kw. but at 5,000rpm you've got the SR with 220kw vs 260kw for the CA. so the CA would be a fairly exciting ride from 4,000 to 5,000 since it more than doubles it's power in 1,000rpm! fair bit of wheelspin in 1st and 2nd i'm guessing. it's still a kick ass budget set-up. now trent, try the same turbo, on an SR with built bottom end and some cams. should make the same if not more power and a bit more response too.

Rich, in my experience the trick is to never let the needle of the tacho get below 5000rpm. Problem solved. CA18DET FTMFW!

I want one of these engines in a little Datto ute so bad.

Yea the CA's gear ratio is different from the SR. If you’ve driven one you know, It needs 3000rpm just to keep the car moving but revs out very quickly. From daily driving the car operates from 3000 to 5000RPM, even compare to stock T25 turbo there isn't really any thing till after 3500rpm.

From actually driving it, it doesn’t feel any lag at all, pretty much just like factory turbo. But when you step it in. ha ha ha ha fun begins, wheel spin on 1st, 2nd and 3rd at 100KM/H jumping from 80km/H to 130KM/H in 2 secs grab on to your steering wheel , hear the loud whisper from the turbo and let your body sank into the seat

On SR probably get abit more power but should see heaps better turbo response and more torque.

Pretty much like the factory turbo? Right......

Looks good at 18psi, but the higher boost level curves start looking poor. Compressor is probably beginning to run out of flow.

try 23 psi the increase from 18 to 23psi yeilds great results, yet from 23-25 it definately hit the wall. i agree it doesnt drive much like the stock turbo but who would want that

[hypergear]

yea, the turbo got more responsive, It must've run in, It had 300kms before the tune. Also I found and fixed that electrical issue, it was in the bit of loom our friend made, Its running beautifully now. I’ll see you next week to dyno the new KAI turbo.

Ah yeah. It does look quite good through the over few runs in the middle.

It must have 'run in'? Doesn't quite work like that. Surprised a turbo 'manufacturer' would be under the impression that plain bearing turbos take a few thousand kilometers to 'run in.'

Ill be in for one of these, once the t3 housings are sorted, or possibly the atr43i, can anyone shed some light on what the specs will be?

my hi-flow is dieing and didn't make anywhere near the power it should have

LoL never you heard turbo run in? all brand new bush bearing turbos will need a run in time of 1000KMs. Boost curve will change once its run in. eg:

before run in:

After run in:

[TTT]

Equinox - whats your problem?

[Swiper the Fox]

Its good to see some guys finally giving the mighty CA a wrap...id love to build a tough one of these.

I think with the right headwork i could get it to match that SR down low.

Someone surely wants one built....2rismo...go and buy one.
