    Shout out to DeLand Dyno for accommodating me and letting me swap out the wheels. Their business info is in the description.

      @@CCAutoWorks no shame in real numbers. Your 60E doesn't eat up as much power. So that'll help. And per my test - obviously wheels don't matter much unless you have some Bubba tires.

    I agree that you can take that as a compliment that your exhaust flows as good as straight pipe, although it is fun hearing that good Ole American v8 make bald eagle sounds 🇺🇸🇺🇸🇺🇸😎

    See to me that does seem odd. I would have assumed a small power loss with the gear swap but i also would have thought the lighter wheels would have made it a wash. I haven't used a dyno much just track times but we all know the gear swap ratio usually offsets the power loss. Im just curious in the weight difference in the converters. The common wisdom tells us less rotating mass equals more applied power. Good video as always keep the education coming ✌️

      The FTI in the truck now and the TSI I took out were similar in weight. (37-39lb range) The factory converter was 50ish lbs - you can see the power numbers didn't change when I swapped it for that tight TSI - despite the weight difference and more efficient.

      @@bluecollarhotrods9781 i admit i was surprised. I didn't expect a 20 hp gain but i didn't expect to see a loss on the graph. Just goes to show its not what we think we know that the dyno tells us the truth. I had a similar finding when i swapped to an aluminum flywheel and stage 2 clutch. Made a bit more power but was slower at the track to the 330. Never completely understood it but it was explained to me as a spinning mass equation. Easier to keep the heavier mass spinning once its already moving. Revved like a motorcycle tho 😂
