Im glad you and David stepped in to explain your thoughts about the HTAT4Z compared to the first version of the HTA37r that AMS reviewed in the beginning of this thread.
My car is down at Pruven now with a new BR HTAT4Z kit....adding more fuel/double pumper, etc. as well. Interested to see what John and Dan can pull out of the car with this turbo.

The main difference between the T67 P trim and the HTA88 with P trim is that the HTA can make a lot more boost
They both spool up about the same and make nearly identical power to 28 psi
After 28 psi the HTA starts to pick up and the non HTA cant really bost over 37 or 38 psi
In my expereinece my modified back wheel gave me about 600 - 700 rpms faster spool up and the same peak power
My big problem with the so called T67 P trim of Gt37 is that its just as laggy as a Gt42 70 mm and it is about 250 whp less potent - the Gt27 is just not a good turbo
Now with the 62/62 frankly, I think there is no reason to get a Gt37
A 62/62 will be loads more fun to drive and just as fast if not faster in the 1/4 mile
I have heard from PT that they are comming out with a billet 66 wheel and that may match up well with the 65 or 62 turbine wheel
in the mean time the FP HTA88 front wheel is really good as an upgrade to the T67 wheel - its the P trim back wheel which is the hold back

I believe someone already flipped out last time someone (maybe you) claimed that in this thread.
I dont really believe that supposed data anyways.
Anyways, this test clearly showed both turbos making the same peak boost and both dropping off over 9000 rpms.
The only difference i see here is that the new wheel is a bit more efficient at those boost levels (41ish) because i assume it has a larger exducer.

No offense here, I am not saying this as a slam of any kind, so don't anyone start any crap.
I THINK if you go do some looking around you will find most of AMS's dyno sheets falling off before 9,000 rpm.
I will look at this turbo on our car and see how it did but I don't think it has much or any drop off in power at 9,000 rpm.
There's more to making the power climb than the turbo charger.

Is the P trim back wheel (that your commenting on) still current on the FPHTA88 with the .82 back housing. Im hoping the back wheel your referring to is the one AMS ran in the beginning of this test with the .63.
PM me if im not making sense or if you can tell me your thoughts. This HTA88 is on my car now so before I have Dan tune the car the info would be hugely appreciated.

Rather than cluttering this thread more, I started this one for discussion on power drop off and such on this turbo.
