Official HTA EVOGREEN thread by FP
Hello Everyone,
We have collected some pretty cool images from our testing phase of the new HTA EVOGreen model turbocharger. Many of you have been long speculating that something like this was brewing. I thought maybe you guys would like to see some of the behind the scenes R&D work that goes into making something that is really good even better
First off this is my own personal car, so nobody make fun of it or you will hurt my feelings. It is a 2006 EVO9 RS with about 19k miles, I drive it everyday. Got the
kid seat in the back and I drop my sons off at school everymorning (awesome kids 5 and 7, the older already races karts
) Stock engine, head never been off. FP4R EVO9 cams (if you don't know about these you will before much longer) Motec 800 ECU, Buschur FMIC, the Garrett core one (this peice is awesome), Full 3" catless exhaust and DP, Delphi 850cc injectors, 342 pump, exedy twin clutch, lots of stock parts too like stock TB stock upper IC pipes, stock BOV, stock inlet pipe etc. Pretty basic car really, I bet it is a lot like most of you guys with EVO9 with the exception of the overpriced ECU. I can't skip the ECU, it is the only way to record the 8-9 aux input channels of data required to perform this R&D work. Full house pressure and temperature at the compressor inlet and outlet, TB temp, turbo tach, Turbine inlet pressure, lab quality certified mass airflow meter, linear position sensor for the wastegate actuator to name what comes to mind off the top of my head. Practically a rolling hot gas test stand for turbos, but has the added feature of integrating actual on car performance to the tires.
The first pic shows how you install the pressure test rig at the compressor inlet. To get valid data you sample mutiple location around the inelt and "melt" the signals together. That is what those 3 taps do, just as specified in the SAE paper on how to build a hot gas test stand with the exepction that we can only fit 3 sample tubes into the inlet and the SAE spec calls for 4. Oh well goes to show no test is perfect.
You can also see what the inside of the inlet air tube looks like where the sample tubes come thru into the inlet air tract in the next pic. You cannot connect a guage to the stock vacuum port at the bottom side of the intake tube, you end up with a venturi that actually draws lots of vacuum as the airflow gets high and get erroneous data. Without this type of sampling setup it is not possible to collect accurate inlet air pressure/vacuum.
The lab meter pic shows the tiny microsecond response time temp sensor at the bottom side of the meter. Tiny little .010" tip thermocouiples with very low mass bodies had to be made by hand in order to get the speed and sensitivity that we need to collect data with.
Same true in the next pic of the test HTA green installed on my car. You can make of the 1/16 brass temp sensor near the outlet of the compressor housing. You can also see the turbo tachometer sensor sticking out of the side of the compressor inlet. What is really hard to see is the linear position sensor on the wastegate. This is one of the more "trick" data streams, really opens the eyes to what the f$&K is going on with the car. Honestly with this combination of data, Turbo RPM, WG position, etc it is no longer necessary to specualte as to what is happening, the facts are right in front of you. This is awesome becasue it lets us focus on the facts, focus on the data.
Count up the hours in fitting all this equipment, the cost of the various sensors, tachs, meters, data acquisistion system, ECU and you will know how much we have spent to make FP turbos the best, but dont tell me what it comes to because I don't want to know .
Anyway, we am almost done, so don't give up on us yet.
BTW if anyone wants to buy any of these sensor setups let me know, we made tons of spares
Also, in case it isnt completely obvious already by the way I post here I will come out and say it. If you want to argue, go somewhere else besides my thread. If you want to disrepect me, save it for the day we meet and do it to my face. If you want to talk about how great something is and that something is not my car or my turbo, take it somewhere else please, start your own thread and keep it off my wave.
BOOST ON!

Awesome test setup! I love shops that do the scientific testing like this. Data like this is invaluable and oviously why you guys make some great turbos.
Are you guys going to post up the collected data or is that going to be kept to FP? Are you also doing turbine backpressure testing or is what you did for the normal green enough, since this is just changing the compressor side? With all of this data pre and post compressor, I would imagine you could build your own compressor map. I would love to see the data when you are done testing.

what are you initial impressions over the standard green?
Another question: will it surge?
