purpose of torque dip

[Porsche]

I suspect the dip is not so much purposeful as it is an unavoidable consequence of a series of compromises required to meet their goals.

You may wish to examine the dyno curves of the Porsche flat-six in the Boxster/Cayman models. Those curves look very similar to our Subaru engine's curves.

Maybe the torque dip is to hold the sweet spot when drifting no sudden kick/acceleration when sliding.

Honestly, I don't mind that this car has more spunk at the upper RPM range rather than running out of juice at the end

Do you guys drive a different car than me? What is all this "low end torque" you keep talking about?

[humfrz]

Oh, well, ...... I just do 90% of my driving below or in the "torque dip", so I just got used to it ....

So, the other 10% of the time, when I crank er up past 5,000 RPM's, it's like the 2nd two barrels of the carburetor kicked it .... or VTEC or turbo or a supercharger kicked it (sort of.....) ..... which makes me a happy FR-S driver .....

It would be better if it was not there, but is it really that hard to learn to drive around it? See what happens when people don't learn to drive/ride on two fifty two strokes? It never it even crossed my mind as being a problem after about a week with the car. Those with MT's have even less room to complain.

It is this very torque dip that leads me to believe that I may end up getting t-boned in traffic, if I'm not careful. I'd prefer not to have it. As a biker, my mindset is, on is on and off is off (the throttle). There's no middle ground! Scary, I tell you, scary!

^^^ this. The way the engine is sandwiched and routing of the exhaust.

LOL I don't want to be a grammar nazi either, but this is kind of funny.

So just for the record, and for future reference:


THIS is a BRAKE PEDAL:



However, THIS is a "break"

And this is to "peddle":

For one, the dip is no longer an issue for me because I installed my FT86SF Catted UEL header last week.

The problem I had with the dip was during everyday normal driving I didn't want to have to drop the car down 2 gears and Rev it up to 5k just to pass someone or merge into fast moving traffic.

That makes perfect sense to me.

BTW does that header give the car a better engine note? Does it sound more like the STI now?

Yeah it has a nice little rumble. I have it paired with a Motiv catted front pipe and the rest of my exhaust is stock. Gives off a stock WRX sound. I'm very pleased with it.

Edit: Here's a short clip of some revving right after I installed it.
