My hopes were that this turbo would make more than a 67p trim t3.. I made 735whp on my 67p trim and all the way to redline it held power compared to how this runs out of breath up top.. im going to go back and compare spool, even though my motor is a 2.0L not a 2.3L..

 

Mike, isn't the 2.0 vs the 2.3 a major factor when comparing the 'running' out of breath issue? The 2.3 just doesn't spin like the 2.0 up top. I know you know that, but since I haven't had the 2.3, I'm asking as much as stateing a point.

 

We are going to do another test in the next couple of weeks on Martins personal car. with a 37R to HTA37R comparison. Martins car is also set to read back pressure and we can do extensive logging so you guys and see where the numbers are coming from

This test was something we had the opportunity to do while the car was here. The real reason its here is to get our drag plenum VSR, some better cams and make some more power... I will post those results when we get them as well

Eric, if this type of test had not been done, there would have been posts wondering why you 'changed' the settings, boost, timing, AFR's, etc. This was a great comparo for the first test results. Good job.

 

Yeah i realize the 2.3 doesnt spin up as high but i just want to see how broad the powerband is compared to my 67p graph.. even with the 2.3 not spinning as high it spools sooner so the powerband should be close..

 

Posted this info up on the vendor testing thread.

 

I think you guys are looking at it to deeply looking for gains/losses

I bet if you were to do two runs back to back with the same turbo, you will find very similar inconstancies.

 

Spot on! How many people complained about the cost of an EVO Green only to gain 20-40whp. Now there are hundreds of them out there! And that is $1000-$1500 for 20-40whp.

If I were in the market for 700+hp there is not question, I'd pick the HTA based on the results from this test. . .

 

Thanks for the info AMS!

 

20-40 HP on a motor that makes a total of 430ish is alot different than 20-40HP on a motor that makes 700+.

 

wait what? no it can't be true..lol!!1

 

but the results don't make sense..

 

Wow, very nice test. Nice to see variables minimized to demonstrate real world application/results. Thanks AMS!

 

i think there is a misconception about the HTA's. seems to me they def make more usable power but the spool is a tad slower. i mean as to be expected because it flows more air, but thats the whole talk about these HTA's.

 

Maybe the 37r. DB's initial test results with the HTA35r .82 showed that it picked up a lot more power in the mid range while showing minimal power gains up top over the normal 35r.
