Even yourself you confirmed once that the gains are +15hp. I don't know why you changed now your mind. I won't continue to argue with you and it doesn't make sense to dig up your old comment. Thanks for posting to my thread.
You do understand the two totally different types of HP being talked about right? The official rated HP is net and measured at the crank without the rest of the drivetrain. The lower number dyno numbers are Wheel HP and include the loss from the drive train. You are not going to get 200 or 205 at the wheels on a stock car. They are not "lower than expected" they are exactly what would be expected from any car when measuring WHP instead of the rated net HP. So, since you can expect about the same loss on a dyno if the 200 net HP cars read at between 170 and 175 then the 205 should dyno in between about 175 and 180. You are still not getting a huge bump from the cumulative 2017 additions and virtually zero from any single one of them. The situation has not changed and no matter how you look at it the gains on the 17 are minimal.

You started the thread it but is not "yours". It is public. I was just trying to help by pointing out something you seemed confused on but you just don't want to hear it. You are throwing away your money on a 17 manifold if you are expecting any gains from just bolting it on and not tuning for it. Even with a tune you will only get a fraction more than you would have got from a tune with the original manifold.
