As per the title Im after a actuator for my Evo IX turbo that will hold 1.6bar to redline. I was looking to get a forge actuator with 1.6bar spring but i dont believe they do one for the Evo IX turbo as yet.

What are my options and where could i get one from?

 

FORGE but its not out yet. I'm getting the first 2 most likely so shoot me a PM if you'd like and i'll let you know when they come in

 

You have a couple of temporary options for now:

shorten the stock actuator rod
place a couple of spacers on the actual bracket assembly that holds the actuator this way it wil shorten the rod travel

Both methods should aim you to obatin more boost without having to spend the moeny for now. Try it, it is a free mods.

is that safe and reliable

 

as long as you don't overboost you are OK. You need a boost gauge though.

The actuator doesn't matter. You still won't hold 23.5psi to redline. It just doesn't work that way - the stock turbo can't sustain boost at that rpm, because it can't flow enough air.

 

Ive got a Evo IX 20G - surely that has enough flow for high rpm ???

 

That turbo might have enough flow to do it. I still don't think it will require a higher pressure actuator to make it happen though, but without having tried that turbo I can't say from experience whether or not it can blow the flapper open. Are you currently unable to hold 23 psi to redline? What pressure does it hold?

 

The BR 20G-9-5 already comes with the option for a stronger actuator. If you didn't get the 20g-9-5, then you made a mistake.

 

Playing the devils advocate here. Have you had first hand experience with the 6 blade and the 5 blade to make that conclusion? Have any of these turbo's been on your car? Just giving you a hard time since every time you have a chance to shoot down the 6 blade it's kind of funny.

 

This is incorrect. The stock IX turbo can hold up to 26psi to redline with an appropriate wastegate actuator. And before you question this, my source is an explicit e-mail from a Forced Performance engineer. This e-mail will be posted shortly.

You can source Forced Performance as well for an upgraded actuator.

 

Thanks Evo Police, fair comment

Warrtalon...I agee with Evo Police...have you had personal experience with both turbos? I have the tc.com 20G9-6 and I am very happy with it - thats all that counts. It was much better than the stock turbo. Ok i made mistake of asking for the 1bar actuator instead of the 1.5bar but thats my fault...not the turbo.

I should also add that the BR 5 blade is not actually a 20G wheel. It is a revised 16G wheel. Rumour has it that it is simply a WR compressor wheel.

Perhaps the problem is with my Profec B II boost controller...its not all that easy to set up.

 

How can the evo9 20g 5 be a revised 16G? 16G has 6 blades. 20G-5 has 5.

 

Funnier still is that all this downtalk of the 6blade wheel happened, "coincidentally," after BR's fallout with TC.com.

Before that, they were totally indiscernible to Buschur Racing's crew AND dyno.

 

Okay the vendor may call it a 20G wheel but it doesnt mean it is a real 20G wheel. You need to look at the size of the inducer, exducer, wheel style for it to be a real 20G.

The 20G9-6 wheel is a real 20G made in reverse rotation - this is quite clear even from BR's previous posts. The 5 blade is supposedly a WR, and the WR is not a 20G wheel, it doesnt have the inducer and exducer size to catergorise it as a real 20G.
