Indeed. I was thinking that since stock Evo's are even less (like ~510's right?) that they should get your staged upgrades first, for the best results.

 

I saw this thread when it first came out and all I can say that BR finally got a product that I will be happy and glad to drop in my car. I will wait and see what happens but I am sure that this turbo will be great around the track.

2 questions for you CONFIRMING what you said:

1- Sending the stock turbo to you asking for the upgrade TI 20G 10.5 hot side will cost $300??

2- Buying the whole turbo from you shipped is ~$1500?

 

If he upgrades the hot side we will get back to point 1 which is lag again. Hope fully it wont surge.

David do you have the turbo maps?

 

Dave, the Turbo I have is a TD05-HRA-16G6-9.8t I have a 10.5t turbine housing and a 05MR compressor cover.. so I should arrange to send you the CHRA, does the compressor cover need any machining? Since I would only have to send you the few parts you need to modify. Oh, and my turbo is brand new so the worst it would need is a balance..

I can ship the stuff to you now so you can put it in a queue for me..

 

I think as long as the turbo has roughly the same mass, surge shouldn't be a huge factor, but then some attention to blowoff adjustments and whatnot need to be addressed..

I am aware that the actual profile of the impeller and whatnot is what has an effect on compressor surge, at higher pressures since there's more air.. but you have other options to help that.

I'd like to be one of the first to get a production unit since I already have the parts needed to do this that I can send out.. And I'm willing to take the risk.. In fact even though I don't normally do this, I can arrange to have one of the local shops do the install and dyno it to see.. (Save me some time) if one of the local shops (Tri-State, Long Island area) wants to PM me and let me know if they can help me out.

I don't mind waiting a bit to get the parts back, I just want to get the ball rolling.

 

We have ran the TD05H turbine wheels with the 20G compressor wheel for about 12 years now. I can't remember surging ever being an issue with them, so I don't see it being a problem now either. Also curious about your combination as I don't remember seeing a stock turbo no an EVO surge either. Kind of odd.

I believe the EVO injectors are rated at 560 cc.

This is awsome, cant wait to order mine. what kinda gains are we looking at from the tme 16g to this 20g hybrid?

 

If you want the 10.5 housing and such with this turbo you are going to pay $1540 for it. If you send me a good stock turbo I will give you $300 off of that price, so $1240.

I don't think the compressor wheel or the 10.5 housing are going to have that much effect on the spool up. I expect this turbo to be so close to stock in spool up.

Don't send in any turbo's yet! Let me make sure the parts even show up and we'll go from there on this. I am waiting myself. When you do send it I want the entire turbo so it doesn't get damaged in shipping. You can keep your wastegate actuators though as they get smashed sometimes.

It has been covered a couple times, you can send in your stock turbo to have upgraded.

Just got off the phone with the turbo shop. Compressor wheels have been shipped and will be in the shop (not our shop) on Thursday. I am having two units built, one with the 10.5 housing one from a stock EVO turbo and sent here for testing as soon as they are done.

Next, I asked about the shaft in the turbo, it is not titanium, says titanium won't work for the actual shaft, it is just the turbine wheel that is a titanium/aluminied mix.


Thanks,

What performance advantage does the titanium/aluminied compressor wheel have over the regular compressor wheel?

 

Lighter and stronger= faster spool and more reliable

 

It's def. lighter ... but is titanium really that strong in this situation?

jcnel.

 

Keep up the good work dave!!

 

Not the compressor wheel, the TURBINE wheel is made of titanium aluminide, this wheel is about 30% lighter than stock so it allows the turbo to spool much faster.

For anyone interested we have the Standard TDO5H-16G, 10.5 turbine housing with the lightweight turbine wheel for $975. This turbo can be upgraded to the 20G later if you want to or you can just have this much faster spooling turbo with more top end power now.

This turbine wheel is a factory built Mitsubishi part, so the strenght I am going to have to guess is no issue at all.

does the tubine wheels share the same specs
