In the previous pages, I have posted a super40 map published by holset. There is 10-15 lbs/min difference between the super40 and the h1e map! The super 40 flows 67-68 lbs/min. I have no direct comparison of the 7 blade super40 and the 6 blade. Nor do I have measurements of the super40 inducer/exducer.
Oh yes, I think if he were running a bigger turbine wheel or bigger turbine housing he would have gotten more out of that compressor. It's a 58mm compressor wheel. It has the same inducer and exducer diameter as a gt3782 with MWE and more blades (higher efficiency). It should perform similarly. Given the proper turbine. Like I said, the small hx40 map really dupped me. I should have known better  . We should give the 8 blade a shot at least, right? I covered my a$$  .
Here's more speculation . . . Interestingly, the second highest flowing map we have flows *around* 60-61 lbs/min. Could this be the 60mm map? 2 mm difference inducer could dfinately yield that kind of difference in flow. Which is significant! up to 5 lbs/min difference is substancial. And is definately an upgrade to the 8 blade. |
Your speculations tend to have me spending $$ all over the place!
I perhaps would have just kept my hybrid and not bought the HX40 6 blade. But I have it now and intend on using it. The HX40 I have is brandnew and not used like the other one (someone recommended
) which was bought from ebay. Got rid of that thing and got my$$ back thank God.
Now you're telling me the 7 blade Holset flows more than the 6 blade but possibly by 5lbs?
Dude you're killin me!!
Never the less I'm learning.
Anyway,here is some interestng info about the turbine hsings I thought I'd post.
--------------------------------------------------------------------------------
After doing a bit more research and speaking with engineers everyone has come up with the 12cm being between a .58 and a .060.... The people I have spoke to knew a good bit about these turbos and I definately believe what they have to say and why they thought that.
That being said it is also a common conclusion that the 14cm is in the .67 to .70 and the 16cm is a .76 to .80...
With the amount of upgrades one can make to the hx35 it is my conclusion that the next logical housing for me to try on my car is the 16cm. I went ahead and a bought a new one as I couldn't find any used ones. The plan is to have it ported just like my 12cm is and then have it ceramic coated. Hoping to have it on the dyno shortly after but without having the car be done at the body shop it makes it hard to say when.
Thats it for the update on pretty solid info.
12cm--.58-.60
14cm--.67-.70
16cm--.77-.80
Best numbers I could get out of anyone hope that helps.

Makes me think I'll replace this custom 14cm^2 HX40 turbine hsing with a twin scroll 16cm^2,even though my HX40 should spool like a monster in the 14cm^2 housing. Just don't want the thing to choke uptop.
Any other thoughts about this?
