Have they fixed the "Torque Dip"? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

dammitcubs · 03-04-2013, 09:16 PM

as in they, I mean the People of this world.

Whether that's by

ECU Change
Intake/Exhaust
Magic Powers
Rituals
Other Awesome things that tuners do

I have been reading up on this Topic and it doesn't seem to come up as much, I don't know if people just got used to it or they found a way to tune it out.

Thanks.

Read the name. It's a dynplot of one of AVO's turbo cars.

I figured that much, but even the turbo cars I've seen seem to have that stupid dip!

AVOturboworld · 03-04-2013, 09:49 PM

it's the 8psi tuning we've been doing recently on the AVO turbo kit. That's on our shop/tester/daily driver, at about the 6000 mile mark on the turbo, so we are tuning up the wick a bit.

On these dynos. They never put stock. I always love seeing values against stock.

So the red and blue data points just different runs (but same setup)?

There is a technical sub-section on the forum where all the little details on this and other FI kits is available. And yes, that graph is two runs of the same setup.

Go over to the technical section FI sub-forum and you will see the baseline and every detail you may want to know.

AVOturboworld · 03-04-2013, 10:08 PM

Red and blue just two different runs, to verify it's not a "one off". You occasionally will get a run that just returns a fabulous number, but never actually shows up again. We don't think that's a valid selling point is all.

Here's an early run of the 5psi setup vs. the same car, stock.

The BRZ intake/exhaust aren't very restrictive and you won't see the torque dip fixed through NA mods.

If you are trying to avoid FI. The way to take out the Dip is headers, and a tune. Nameless and p&l tuning has post up great numbers

Any dynos to show the difference?

Look it up. In the engine,exhaust section

Weren't there some charts of an exhaust header from one of the developers that not only filled in the torque dip but created a rise there? Can't remember who the vendor was.
