But I am not seeing real great results when compared to the HTA35R It does make more peak power , but not huge , and it is far more laggy than the 35 . The HTA35R power curve is just so much larger the the 37. In alot of areas of the graphs I have seen the 35 is up on the 37 by large numbers on most rpm areas of the graphs , until the very end peak power the 37 pulls past the 35 but usually not till the very end of the pull. Its a toss up. seriously the average power across the board on each turbo are real close. Just the 37 peaks a bit higher. --- _[View the full topic](https://forums.speedlife.net/t/evo-thread/197829)._
