That was my second guess. It was either that or Swedish since those Swedish chefs really have a dirty mouth on them.
I don't know how Sesame St. was able to air that guy without constant censoring.

Btw, I enjoy puns. Does that make me punsexual?

As long as you are mashed, baked, or scalloped next to that steak, we can be friends.

Edit: also love you as a steak fry.

Why can't you people stay on the damn topic ………

Ok, +25hp.

I'm talking about the steak fries.

I just love it when you talk cooking to me, really gets me hot.

If you compile weights and outer diameters of the parts you are changing (stock and aftermarket) here I can give you a decent estimate of straight line performance change based on weight/inertia sometime this weekend. The model isnt ready for prime time yet otherwise I'd just post that. Also that assumes you are relatively close to stock performance. If that's not the case, let me know and we can find a workaround.

The model won't account for vibration, but it seems the design of the fluidampr is more focused on protection than performance. From what I can tell, the vibration energy is transferred to the silicon and lost as heat for the most part.

Yes the Fluidampr is 5.8lbs but supposedly only 3.8lbs rotational (idk how that works) I saw a dyno comparing vs stock and light weight, and it actually lost about 1-2tq downlow and gained 1-2 top end.
Either way it seems to “protect” the engine from harmonics better then stock which seems beneficial if you are modded. Stock I think is 5.1lbs?

The DSS driveshaft is 2.75” diameter 12.1lbs, havnt found stock driveshaft specs from looking at it today (forgot to measure it...) it looks 2.75” for 2/3rds then the joint then 3” for 1/3rd of the driveshaft and 24.2lbs?

Assuming a 200 crank hp 170 whp 15% drivetrain loss. What % if any of that is the driveshaft and does lightening it reduce the loss?

That fork looks edible.

86TOYO2k17: mechanical losses are what is spend on friction in various parts of transmission. Driveshaft or lighter flywheel or lighter wheels won't change a bit any of those losses. If you get upto speed then power needed to keep driving at that is absolutely same. Only things a bit affected is acceleration or slowing down, to get to that speed, when one needs to overcome rotational inertia/spend energy on that. Not mechanical losses. And if they are "affected", then it's because some dyno miscalculates power from acceleration wrongly assuming that power is only thing that changed, not because "X hp-s have been freed up, mechanical losses are less by Y%". Also, there is not much rotational inertia to be reduced with lighter driveshaft (unlike eg. flywheel or lighter wheels). Rotational inertia may depend on mass, rpms, and mass distance from rotating center. Flywheel has more of a second, it & wheels have mass & distance from center, but driveshafts have too little of diameter to make much difference. Yes, some very slight difference will be there (as from lightening in general) but probably below butt-dyno detection treshold. Main reason why one should consider aftermarket drive shafts is to get one that handles more torque then stock one if going high-gains forced-induction.

The protection of a more harmonic crank pulley is probably good, but probably makes no performance difference. The rest would probably make the same performance difference as taking a big shit before driving.

I have a carbon drive shaft and I only noticed the smoothness difference from the 2 piece. I could feel the vibration with the 2 piece before it planed out.
