HyperGears Twin ATR25 Turbocharger VG30DETT Build up Thread

hot tank

the hole engine, its a fkn mess.

 

If this fits without modification why is the dump cut?

 

You sure its been cut? do you have a photo of stock dump pipe? Thats what its like when we pulled it apart, we never modified the dump.

Even if the dump pipe has that bit on the top Its not on the way of any bits of the turbo.

 

Since you have the engine out and all, can you please take pics of the turbos side by side and compare? Those are huge compressors and turbines if the housing is still the same size...will be interesting to see the difference.

btw FYI, you got the specs the other way around.

On your website:
Compressor wheel:
Inducer: 49.5 mm
Exducer: 60 mm

Turbine wheel:
Inducer: 46.2
Exducer: 53

It should be:
Compressor wheel:
Inducer: 49.5 mm
Exducer: 60 mm

Turbine wheel:
Inducer: 53
Exducer: 46.2

Remember the inducer on the turbine wheel is the overall measurement (like the exducer of the compressor wheel)

Will be great if you can post pics - both hot side and compressor side. The turbos you have are bigger than the discontinued sports 550's which were t28/t28 in manual z (.63) housing. Only concern I have would be lag, pretty sure you can reach the hp you are claiming. Dyno result afterwards will be interesting.

 

Of course its been cut. You can't make a cast part with a 90 degree cut in it. The tooling wouldn't allow it.

 

Your going to get shit all gain with the stock and restrictive dump pipes, chuck on some tune agent dumps good bang for buck for the price.

 

More updates. trail fitted both side turbo. How ever left hand comp inlet pattern angle is slightly different to stock.

The Inlet pattern angle of both stock turbos are actually different. will have to make custom inlet pipe for both turbos or just fibracate the left hand inlet pipe

Left hand turbo:


The actuator is awaiting to be fitted, and the dump pipe needs to be securied.


Right hand turbo:

 

This could be interesting to see. Comparing ATR2x and 3x Turbo cores.



Please note we have decided to use a smaller Turbine wheel and a different trimmed comp wheel for better responds and efficiency on the ATR25. The housing of the little suckers is just too small.

 

not this shit again............

 

I think you blokes are barking up the wrong tree. It looks uncut to me

 

Yer from that angle it looks uncut

It's been a very long time since i've seen stock dumps. Not to mention that angle sucked

 

Im gonna have to dig out my old dumps cos im sure they dont look like that

But then its been a while since i looked at them too

 

waiting for me? my test wont eb fair since i have done countless other mods since then. AS i said before there have been dyno sheets posted before showing little to no top end gain but quite a bit of midrange.

It has also been noted by other members that their cars were unable to boost over 15-16psi with the stock dumps where as with the PZP dumps they can boost more.

When i had a manual boost controller in mine, it could make 20 psi at under 3k RPM witht he PZP dumps.



But this is not the point of the thread. There have been 2 big threads in relation to you dislike of the PZP dumps, i think that is enough

 

Let me correct you.

Let me correct you there . Firstly there is a difference between statements and opinions . ALot of people have opinions on the pzp dumps and so pass comments on them . They are well within their rights to do so.

You are missing the point about proof. You were criticised for not providing proof when you were advertising THE BEST dumps on the market. It is an entirely different thing to make a comment on a product.

Nobody posts dyno sheets on a kakimoto exhaust for example but they still have the right to say that it is a good product without you coming in and mouthing off.

To correct you again i would like to make it clear again that yes i can post dyno sheets but there is no point as the car is running in an entirely different state than it was.

As i said before there have been some sheets posted but in 15mins of searching i couldnt find them so i gave up. please feel free to continue the search.

Id like to know if you have dyno sheets to support all the comments you make on products while pimping them for UAS? Have you got any for the famous king shit dump pipes yet? or are you being completely hipocritical?

Haha. I was actually refering to your dyno sheets. please re-read the replies in this thread and then tell me you still had a 0kw increase

 

ENOUGH!

This side argument is detracting from the thread. No more posts will be tolerated on the merits or otherwise of TA dumps.
