Kinugawa Td06-20G 10Cm Vs Atr43Ss1

E85 can only help, at least you would pass the emissions test.

Even with a decat you reckon scotty?

Have an emissions cat at home for those 'test' days. It wont do any harm if your not on the loud pedal.

Std high flow makes 100kws at 3000RPMs and maxing out at 320rwkws on E85. Note this turbo hit 20psi at 3400RPMs, there isn't many turbos out there can do this without chocking the engine tho. Pump 98 fuel usually makes 40kws less. It is cheaper then what cost you to buy a TD06, after testing all this TD06 based turbos, I'm fairly sure it is far more responsive then any thing based in a 10cm turbine and makes more power internally gated.

Added 270214:

labeled dyno reading from 21U high flow internally gated on Stock manifold E85 (take 40kws off for P98 result)

How does the 2IU highflow compare to the atr43ss1PU?

Looks like they both get full boost at 3400, but the ss1pu has 30rwkw more in it? How much physically bigger is the front cover on the ss1pu compared to the highflow?

What's the difference between the two on the street in terms of driveability?

I think the SS2 or a OP6 high flow will suit your car better.

Reason is I've found out that your car is a AWD GTS4. By experience not only that they are 12% lake in power to the RWD Skylines, they also run the turbine end hotter. The end result will be more successful with a larger rear housing, that makes the engine much happier too.

Other thing need to be understood is turbocharger isn't magic, making 20psi by 3400rpms requires high exhaust gas velocity in low rpms, which does not satisfy the flow requirement in upper rev range or compensate for high boost. There for most 500HP rated turbochargers kicks in 20psi region around 4000RPMs mark using a larger turbine housing.

Solution on the extreme side is high temperature variable turbine geometry system, heat resistant silicon nitrate ball bearing system and high efficiency compressor wheel (ATR43SS-Alpha system). On this setup we can have 20psi by 3500RPMS, make good power while not chocking the engine. Sadly this turbocharger so far can only work on an externally gated system, complicated to build and expansive.

Is the cost of the op6 highflow the same as the cost of the 2IU highflow? I can't seem to find the 'high flows' on your website?

What's the op6 rated too on e85? Do you have an op6 e85 dyno sheet by any chance please?

[hypergear]

Cost to high flow is same.

All the results has been indexed on page one of my high flow thread. Along with many other.

Note 4WD systems usually creates a bit more drag, acts very similar to higher dyno ramp. Which usually ends up with better response and less power, probably because the combustion discharging temp is higher under greater load..

Have you done much testing with the addition of cams regarding boost response?

Can't wait to have an fresh highflow under the bonnet

[hypergear]

The cams I used was 264 dur / 9 Tomei from CJmotor, and only CJmotor has them. That was a waste of time and effort, made 3kws of power differences for 400RPMs of lag. For the HP level expected, standard cams works best.

Jeez.... Glad I spent $700 on tomei 256 poncams....

Stao was using cams that lost the vct, which explains the drop in response.

You will get a benifit using your cams

[boostn0199]

the 256 ones are fine they do give a nice gain in midrange and small increase in peak power.

Oh good. Will be good to see how it goes on the dyno

[ARTZ]

I like the way you just come in here fudging in whatever dyno results suit you at the time...

I guess it's easy to do when you have a book full of them..

[hypergear]

Unfortunately building turbochargers isn't just about turning lathe, people isn't just buying a turbo, they are buying their desired HP goal. Ensuring the outcome I must not only be an excellent engineer, the engineering must be closely related to the power generating subject which on SAU is a Rb25det motor along with all of its components.

Yes I have a book of dyno sheets contain 1806 pages. that recorded the behavior of a Rb25det in many different aspects, its very useful in directing the shortest path archiving certain performance goals.

[scotty nm35]

I think the issue he was mentioning is with VCT off it fudges the figures a fair bit. You can't say a certain set of cams is no good just because it din't work on your particular setup.

I am of the opinion the stock cams are usually the best option anyway... Upgrading cams is the last thing I would suggest, and only on well sorted high power setups. More important is keeping the gas speeds up.

[hy_rpm]

In saying that std cams will only be the best to a certain to a certain power level than they will become a restriction

[hy_rpm]

Yes they will have better low range power because nearly every aftermarket cam shift the powerband slighty up but makes more mid to top power

But with staos car setup it wasn't a fair comparison with stock vs tomei cams as the std had VCt and the tomei didn't

I don't know much about rbs but maybe cause the duration or lift VCt is incompatible but it would be better to compare a smaller aftermarket cam with VCt vs std cam then you can say if it's worth changing cams or not so his test was flawed

More boost should fix that.
