AMS Built 2.0, 850r, and all supporting mods 543@ 23psi pump 93 ONLY!. Can't wait to see his e85 and q16 dyno results should be a monster.

To answer some PM's in public and save me time I want to share some info.
The 3582HTA turbo was our standard issue turbo that had been on a car for months, not a hand picked ringer of any kind. It ran a .82 A/R turbine housing. The compressor cover on our 35HTA turbo is smooth inlet bell shape recirc type with the 360 degree gas vent all the way around.
The PTE 6265 turbo also had the same size .82 A/R housing but it did not have the full surge port style cover, it had the swiss cheese style cover on it.
The test was done recently so the temps were not cool, ambient was around 90F. Both sets of data were temp corrected using SAE correction (industry standard) however since the atmospheric conditions were the same for both tests, the CF was the same for both tests also. With or with out a CF the graphs appear the same, only the y scale on the chart changes very slightly.
Lots of guys asked for mods lists, but this test did not involve changing any of the mods on the car other than the turbo. The mods list was the same in both tests, and the car has a full bore race engine like I pointed out in the OP. Full bore means put a check in all the boxes, yes.

I have a car here with a hta 37r and i also have 6265 now in stock.. Im going to see if i can get the customer to let me test those 2 turbos against each other on the same car on our dyno.. It will be when i come back after the shootout so ill keep you guys posted as well.. Thanks for all the info Robert..
The 62/ 65 is not going to work nearly as well as the HTA88 a/k/a Gt37
The turbo we need to test is the 62/62
The 65 wheel is comprable to a "P trim" wheel its way to big IMHO for a 61 or 62 compressor wheel and the laggy results show
The HTA Gt37 will be the same lag as the 62/65 but make much more power as it has the much larger compressor wheel

if 6265 spooled a lot later and made little less on the dyno i really dont think that the 6262 will be even close to same power as the hta but we will see how it will spool.

You know, I honestly believe it will make more power than the HTA35r, how much not more than 45-50hp if that I would say, but here is the thing about that. I believe the HTA35r will whoop its *** all the way up to about 7k and that is where the 850r will take over. I'm a stroker guy and to me the power gained isn't enough to ofset the lag you get with it. My pwr ban is done "safley" at 8200rpm. I like the linear powerband that the HTA provides under the curve in normal driving conditions and make 45- 50 less whp than the next best laggier thing out. Eh I guess you know my answer to that!
