Questions for Justin...

[okm12346]

Justin, I have a .55 BEP housing made for P-trim turbo. I had it machined to fit 8 blade hx-35. Now the exhaust wheel isnt as tight inside the housing diameter as shown on the picture. Theres a good 1/8'' between of wheel and housing.

My question is : do you think that will pose a problem with spinning the turbo and maybe slower spool.

and

Do you think the HX-40 8 blade exhaust wheel/shaft will have a tighter fit, or should I buy an exhaust housing for HX-35.

1/8 is huggggggggeeeeee that would cause lag. Usually the clearance is thousandths of an inch.

You do know that 6,7, and 8 blade holsets have nothing to do with the turbine right? Thats only compressor spec. Lol for instance,
My 7 blade hx40 has a 12 blade turbine, and a 12 blade turbine might e of different size than a 10 blade turbine.

That much "Tip Leakage Loss" will not only hurt spool, but impact efficiency a good bit as well.

Losses as much as 5% for every 1% channel height gap in some cases.

Thats some good reading right there.

Right because a P-Trim exducer is 64mm and the HX35 exducer is 60mm....and you can't add metal unless you get a sleeve welded into it.

My question is : do you think that will pose a problem with spinning the turbo and maybe slower spool.

Yup- you'll be lucky if it makes boost at all....if it does, it will be quite slow.

Either buy the correct housing, or buy a HX40 turbo and have the housing re-machined to work with a HX40 turbine. Don't use the HX40 turbine on your HX35.

I figure while i have the turbo apart, how much of a pain would it be to upgrade turbo from the stock 14b to the evo3 16g from Tradergreg

Here's some info for you:

Not to mention machining of the compressor cover and also the 6cm housing could potentially improve spooling but limit airflow, which might suck depending on what you want...

A huge pain. To do it properly, you'd be throwing away everything except the center housing...which would need machined.

Much cheaper and easier to just buy a used Evo III 16G and rebuild that.

not sure how that thread didnt come up in my search, but thnx c2
as far as what i want is a DD that can put the hondas in their place at the lights

thnx justin, got any for sale?

If I did I wouldn't be discussing it in the tech forums seeing as I'm not a Supporting Vendor.

I would assume that having a gap like that on the compressor side would have similar results?

 

[nfernotalon]

Now that I think about it I had that big of a gap on my h1c and my bep housing if not more. I bought my housing used I wonder if thats why I could only get 340hp at 27psi on e85. Do you think thats a possibility Justin? Maybe it was an hx40 housing?

 

[Archer Fabrications]

^thats horrid..... And likely

Yea I didnt think much of it though

 

[spadepro22]

Did Holset change from blue to black labels on there turbo's?

 

[Archer Fabrications]

They have a few different label colors, look on their website black, blue, silver

Hey Justin I would like your input on going internal vs external on my Hahn 16g in a Bolton housing pros and cons. Want to get the most out of the turbo with rock solid and steady boost till redline. Internal setup consist of fp8cm housing with evo3 o2 housing and Kinugawa Billet Adjustable Turbo Actuator Mitsubishi Starion TC05 TD05 TD05H if I could make it work or external fp housing with recirc o2 housing. pros going to internal is "stock look" still use heat shield, external= better boost control and easier when I upgrade the compressor over(fp green)

You're absolutely not going to have trouble with creep with a Small 16G. If anything, the boost is going to trail off in the higher RPM's....especially if you're running above 20psi. An external gate is not going to fix this.

Just make the best of it with an internal gate and save your money to go external when you jump to a much larger turbo as upgrading your existing 16G to something in the FP Green range is going to cost some serious money.

 

[T is for TURBO]

Justin, I just got my turbine housing (8cm) back from getting ceramic coated, and I'm about to reattach it to the CHRA. Do I torque the clamp until it's tight? Or do you suggest a specific torque value?

Thanks!

 

[JusMX141]

I'm sure there's an actual torque value, but I tighten it until it's pretty tight as having one of these come loose would be catastrophic. Don't over-tighten it to the point of breaking the bolt, but definitely don't leave it loose.

hey justin just throwin this out there ...i have im pretty sure a 70 ar s200 bep 47 trim turbo ...i have now an hx35 8 blade what im wondering is do you have or know of a bep internally gated housing for the hx35 because i have a stock manifold and its either get the new housing or custom make my tdo5 to t3..... if you know of anyone i will trade straight up and maybe a little to boot for you its in almost perfect condition no blade grinding or scuff marks ......thanks for your time

 

[Archer Fabrications]

.55ar internally gated
Bep for hx35...

They're no longer in production so if you find one it would either be used or old stock.

Also, this isn't the classifieds so no talk of buying / trading deals in here please.

 

[nfernotalon]

Justin does the hy35 exhaust housing bolt up to the chra with 6 bolts? I might get this bolt on housing from my turbonetics 50 trim machined to fit the hy35. That way ill have a bolt on hy35. What are your opinions?

 

[JusMX141]

Nope....v-band.
