Damn, those turbos make me feel all tingly - really really keen to see results for some of these things. What I wouldn't do to get you sitting down with me and a few other people over a few drinks to pick your brain and experiences haha

Here is some quick pics of the new level of compressor wheels we test these days.
Its the thinner blade we have ever test. its 0.5mm.
Its extended tip 10blade wheels.
This unit on the pics its capable of flowing more than +1800-1900hp and its one of the large frame turbos of the test. I will upload today some more units of this test.
We prepare large line of sizes for the 10blade units.

Compressor wheels look fantastic, very well finished.
Have you done any testing with the strength of the wheels especially being so thin... high boost levels, shock loading, compressor surges, etc.
Good stuff!
Sweet.
The newest GTX wheels (GTX28 series) are also 10 blade, extended-tip designs and the compressor flow maps are pretty impressive on them. High P/R and fairly wide overall with surge lines of their little 6-blade counterparts.

Hi,
As I told to a previous post we decide to test all the most leading edge high performance turbo on the market, some of them will be on market during this year, and some custom untis also from us, power starting from 1400hp to 2200hp and be placed and tested to our 13cr 4G63 race engine. Some of them is the new Garrett Gtx55 and the new BorgWarner S500sx.
This will not be just a simple test as we don’t want to see just the power of its units but we will collect many data.
There are 3 general tests we want to do, performance tests (compressor performance test and turbine performance test), Mechanical run test that we cant calculate it as we like, as we cant measure the vibrations vs water and oil inlet and outlet conditions, and the Load line test that shows the thermodynamic stability of the turbocharger, also this possibly cant be as we like, because the flow volume of these turbos working in high p2c/p1c, are too high and we cant get our engine too high p2c/p1c to see the operating range of the compressor maps for some units.
Also our small 2ltr 4g63 engine possibly at some large units will "fall" at surge line in low boost tests.
As matter the efficiency calculations will be to determine the compressor and turbine efficiency at each of the test points. Since the turbocharger will not operate adiabatically, the heat transfer losses/gains in the calculations must be included.
To explain it, the isentropic or adiabatic eficiency of a compresor is the ratio between the power that would necessary to operate the compressor in an ideal adiabatic situation to the actual power that is necessary to operate the compressor. The constraint is that the inlet temperature and pressure, and the exit pressure are the same for the ideal adiabatic compressor and the real compressor.
As matter the turbine side also, the heat transfer rate from the turbine and compressor can be calculated by determining the heat rejection to the water and oil systems, and then calculating the heat transferred from the turbocharger casing. This combined with the backpressure gauge can show us the exhaust side.
Some of the units we will test.
And some of our measurements units we will use.

We also working for the stock frame units.
Just a spy info, we manage to fit an 80lbs/min 11blade comp wheel to an antisurge compressor housing and 10.5cm turbine housing with new billet high flow turbine wheel.
We will start accept preorders in 15days for the first 10units we have already start produce.
Prices will be from 1850-2400e and 2500-3000e with dual ballbearing and titanium compressor wheel options.

Can the turbine side keep up? Seems like the 67mm turbine wheel FP uses is about the biggest you could stuff into the Mitsh TD05H CHRA.
Would LOVE to see this billet turbine wheel though, sounds bad ***.
