Ace and Nameless header comparison

I will try to report after I do it (if I dont forget). I still have the original dyno plots laying around (and can probably ask for an overlay of both of them).

Unless the temperature and barometric pressures are identical from your first dyno, and on the same dynamometer, the comparisons will be moot.

Yes, it will not be a scientific test at all, a few horses of differences doesnt say much, except that the engine hasnt changed much. But what if I see -15whp? No changes in weather should show something like that, altho it shouldnt be the case.

Maybe you need clarification on what 10/10 means.

There's a few dyno sheets around that show the Tomei UEL performing just as well or better than some EL.

keep on drinking that kool aid

Stop arguing about UEL vs. EL. You don't even know the science between the debate, or why one header works better than another. If you did, you'd present evidence based on port volume, velocity and flow at specified RPM, where you want to make peak torque, and how and why you want to collect the header runners.
Arguing about UEL vs. EL without knowing how each header flows and how it's scavenging exhaust pulses is the same as arguing over snow tires vs. R compounds and not considering where the car is being driven.

Do you have the original picture that went with this post? Interested to see the dyno results.


Thanks,

I just switched from the Nameless header to the Ace and wanted to share my experience. This is on my STX prepped car, mods are identical between dynos other than the related front pipe/over pipe. Both tuned by Church via ecutek, same dynapack, runs are 2.5 years apart. CA 91 oct.

Mods:
TRD intake
Perrin 2.5" resonated CBE

Nameless setup:
Early release tri-y header w/3" outlet
Nameless 3" over/front pipe w/cat, resonator and helmholtz. Tapers to 2.5" at CBE.

Ace setup:
Type A 350 tri-y header and over pipe
JDL 2.5" front pipe w/cat and resonator (ultra quiet)

Green is Nameless, blue is Ace

Hey whats the story on the trailer with your BRZ? I would love to get a trailer but I would be afraid of towing in this car...has anyone else done it? I know it isnt related to this post but I saw the guys sig..

Why are you asking this of a person who hasn't posted on these forums since 06-01-2017?

[Lantanafrs2]

Usual progression here. Buy car, mod car, sell car, buy faster car. If I'm wrong, I apologize

I see the dyno graph. I attached the picture (as a zip, since the forum limits the size of jpeg's).

Ah, yes this thread. I forgot there is a torque dip with the Nameless headers. I guess I don't feel it much when I'm driving.

I notice it pretty much as it is shown on the dyno chart the OP posted. But I do not have a specific tune for this header.

I don't have much of a reference then. I do notice a nice zing in power past 4k rpm. So maybe I'm just accustomed to the torque dip? Either way, the dip has never really bothered me.
