If I was already cruising a med RPM and then wanted to accelerate it would take for ever to get to my target boost, normally in time to shift. Makes 330 whp and sucks most of the time while driving != works to me.
I have a stroked ej205, so my build may be non-standard, but with my rotated Garrett gtx3071r, the drivability is night an day. I know it isn't exactly the same, but I provide it as a counter point. I have more power everywhere (+100 whp more on top, +20 lbs tq down low), get to peak boost several 100 RPM faster, and there is not much lag off of boost in cursing situations whereas sometime the FP sometimes would not hit the target boost. Making over 400+ whp and being responsive == works.
It's not non-precise. My turbo works great, excellent boost response (better than any other similar sized turbo i have tried) and it makes great power for it's size. I say it works because of my graph and results.
Besides, this thread is about the HTA71, not the HTA68. Many people have had sucess with the 68. I'm sorry that you had issues with getting it to work for your particular application. However, the HTA71 is an excellent turbo and my car is a stellar example of that.
FP turbos have been working well in this segment for years, the sucess of the Green, Red, Black, etc shows that they make good turbos that work well. Your experece with the HTA68 (arguably their most controversial turbo) shouldn't define them as a company or the products they build.
That was the basis of my statement. The HTA71 isn't hype. it really works.
