I made 6 whp and 13lb-tq adding a drive shaft shop carbon fiber driveshaft (1 piece) and putting a 1.4lbs lightweight pulley on a 2015 STI. Total weight saving was 19 lbs(rotational drivetrain weight ). I posted the results on IWSTI 10 years ago. At the time drive shaft shop only sold one prior to mine and no one knew if the driveshaft would fit because it was for the previous model STI. We drilled the 4 holes and put thicker bolts to make it fit on the rear diff. Boston line, those 19 lbs weight reduction on the drivetrain on a mustang Dyno to all 4 wheels translated in a greater output of 6whp/13lb-tq with no changes on the tune, just a straight bolt on (prior to a custom tune). The engine revved faster and the drivetrain was very smooth (no vibrations).
So basically moral of the story here is to just leave the car alone and just enjoy it. Software, tune, fuel, and above all time is money lost for not a quality end result. Just track the shit out of this car as is. Love the car and the blacked out theme👌🏻
If you just want to have fun I would agree with you 100 percent! Good tires good brakes and done. I’m trying to race in a few different classes and need all I can get to be competitive. 😂
For the street, yes....but if you track the car. For such a low power car, gaining nearly 10% through the entire power band is worth while. Especially considering that you can also adjust throttle behavior etc.
Intake filter removed + Tomei non-appearing manifold + HKs Regamax Sports + no catalyst 57c 18 9.5j 38 mapped today. dynojet 216hp. Why is it so different from you? Octane rating is 94 or higher.
Well done on the video. A little bit off topic but what Recaro seats do you have and can you do a measurement from the seat cushion vertically to the roof liner? A bunch of us taller people are looking for seating that will give us more Headroom for our helmets at the track. Thank you in advance
Am I missing something. Stock was 208whp pump gas. 217whp pump gas tuned. 224whp e85. +7? Biggest gang was tune on pump. +9. On good e85 maybe +9, but what’s the cost to go to e85 vs just tune?
@@phelpsgarage4202 Lol. You think that UEL is what boxer engines sound like. That’s cute. I bet you think the WRC Imprezas had the “Subie rumble”. 😂 Literally nobody in the know has run UEL for twenty five years.
Wrong, the UEL's generally perfom better than the EL headers on this platform for whatever reason, just look at some dyno charts. Plus, sound is subjective. You might think its average, I think it sounds great.
