i can't tell you anything about the CHRA BUT

i am running their 20g wheel and compressor housing and its been great so far (under 1000 miles)

 

wow when you drive 5000 miles please write to this topic for more info about this product

 

Any more pics? Looks legit...

 

and im not understand who made this???

 

No high mileage update yet. I am still only at 900 miles. My island is small so I might do 700-800 miles in a month.

It is still going strong though. I plan on increasing the boost from the 11psi it is at now to 20psi as soon as my new to me boost controller arrives.

 

Hi, any news on this ?

 

Any results? According to their website they are Japan made. I imagine they would perform just like any 20g upgrade. I just happened to notice them on Ebay so was curious if anyone used them.

I'm thinking about buying this turbo, but at their site written what "For application on EVO 4-8, EVO9 compressor outlet pipe is required."
So there is a question. Which difference between Evo 4 and Evo 9 outlet pipe? It's so necessary to have Evo 9 outlet pipe for it?

 

A few days ago installed Arashi t/c for Evo IX.


~600km flight normal. Boost under 0.9 bar.

 

any updates on these things?

I'm eyeing one for my Evo 7 because i'm only chasing about 400hp MAX.

I should just contact them and ask if they will sponsor me one lol

get the name out there a bit.

 

After ~1100km max boost is only 0.7 Bar, and it's bad
And if actuator was 1.2 Bar, then why after installation it was only 0.9 Bar max?
Problem with wastegate flap?

If I remove hose from actuator, it's boost over 1 Bar.

 

Its cause the metals they use are akin to particle board but in steel form....the flapper is not sealing good and the actuator probably is made of paper or something chessy. Not trying to slam just being real. Get a stock actuator and test it...or if you wanna get deep..take turbo off an look at the flapper sealing surface....youll see what im talking about.

 

did you check the actuator preload ??

 

BoostINurI, so, how I can fix it?
I'm checked actuator with hand pump and manometer for response on pressure - it really fully opens gate at 1.2 Bar.

todd6027, yep. It was good enought, and after increasing (1-2mm) preload, boost now is only 0.7 Bar. Before change was 0.6 Bar.

 

Yesterday was kinda funny. Boost was gone. Fully. Driven as 1.5L engine car or something like it.
After 1 hour in garage (don't touched engine) boost was returned O.o
I'm think, my bypass valve just freezed at -38°C and was always opened xD
But maybe actuator is working wrong too.

And lately, increased actuator preload. Forgot to connect hose to actuator. Boost was 1.5 Bar
Connected hose - under 0.9 Bar ^_^
