Dyno -- Stock vs Ace Header / Tune (oem everything else)
 

Just got done getting the Ace Header and EcuTek tune done on my BRZ

Have had this car for a year now...nothing but great things to say about it...mainly a track car for me and the ability to drive every second of every session vs ultimate power is important to me ...that is why the engine was left complete stock for so long.....finally pulled the trigger on the header and tune though

the rest of the engine is still stock, stock intake, stock front pipe / exhaust, etc....the car being quiet is important to me as well.

Happy with the results..midrange power is impressive.

heading to Sebring this weekend to see what the dyno #'s actually do for lap time difference on the track

Thanks to Real Street, Circuit Motorsports and CSG for their assistance

Only ~13HP gain? That doesn't sound right, but maybe I'm misreading the graph.

Look at the TQ dip area. IT'S GONE!!!!! :thumbup:

How much louder than stock with the headers now inside the cabin?

What version ace header is that? Looks like 25-30 hp/tq gained in the dip!

has an interesting sound with header on the rest of the stock exhaust...a bit raspy at lower rpm and partial throttle but sounds nice at wide open throttle...on a scale of 1-10 on how much louder than stock header it is I would give it a 3 ...a noticeable increase in noise but not out of control at all.

This is the Ace Type-A, 4-2-1, 350 collector

Sound clip?

Hey IPG,

Thanks for the information. I consider myself in the same boat as you in that this my daily which needs to keep the sound reasonable, but it is also my HPDE and autocross car that could use a little more oomph to go with the NA reliability.

Overall, the results you show are great gains in the midrange (TQ and HP) along with some decent HP gains on top which is very important at the track, especially without the use of E85.

Also in to see the results for lap times before and after (albeit with multiple variables here) :)

Thanks again,

Good to know I plan to get the 350 this winter and install it for spring.

Nice..now get some E85 in there and make 190whp

Impressive result, still looks like it's the best header on the market. Although result not as impressive as the "independent" dyno from the only vendor that sells it lol.

Nah...it is not prevalent around here and I am not going to chase it all the time or bring it with me when i go wherever i go to the track at....keep it simple...93 octane it is.

we may work on a custom front pipe with a nice resonator to free up some power from eliminating the next cat while still keeping it quiet...there is some left on the table there but max horsepower isn't what this car is about for me...tinkering with it is fun but on the track is where the excitement is really at.

Three stations in Orlando and a bunch in Tampa. It is a pain. I'm about 10-15 miles from a station as I'm near UCF. I do usually grab a tank plus 10 gallons at a time.

Been to the track yet? Before the ESC best I did was 14.3 @ 97. :thumbsup:

almost a 40ftlbs different in the dip area and a smooth torque curve

HP aside, header is worth its weight in that alone.

Racetrack station in Lantana has e85. Pump says 51percent minimum ethanol so im leery of using it without a flex fuel kit.

I bet the OP would get more power out of it if he invested some more time on the dyno, or purchased a Ace-specific tune.

The progress made in power is available for anyone to see; you're more than welcome to visit Church Automotive Testing yourself, to see how the power was achieved (and how many hours were spent on the dyno to achieve that repeatable result).

Time for a rematch!

Alright well let's put your money where your mouth is ....I have access to a dyno anytime and I have no invested interest towards anyone on any of these parts.....this isn't our first rodeo ..... You can't just say things like we need to spend more time on the dyno or buy your tune ....let's see you prove it

Are you asking for a free header? Or to become a dealer (I note you're a vendor of competing parts)?

I think the performance of this header is well established.

From what people with flex fuel kits in the car clubs use the e85 never really goes below 70% or above 83%. We don't get the "winter" blends down in the 50s.

I don't have flex fuel. I use map modes from RaceRom. I have a e65 map for fill up #1 and/or winter time. Then an e80 map for fill up #2+ and summer time. There on the lean side which is safer on e85. Rich can make you knock actually. Some don't know this.

Looks good! Can't wait to add this to mine soon. Was CSG selling the Ace header when they started the independent review thread?

Nope. That result is what convinced CSG to sell the header.

Correct. It's the result of approximately 80 flashes, with 4 maps per flash, for a soft total of about 300 iterations and nearly 500 pulls.

On Elite Performance's dyno, tuned by them.

Is the extra HP at the expense of the torque dip? I get HP would be more important on a racetrack but what about for autox? Couse dependant?

Wondering cuz I currently have Tomei but am highly considering Ace for a competative build.

I'm not exactly sure what you're asking...

The brief dip in the torque band is often caused by a cam timing anomaly. Different ramp times and/or different gears alter that false dip on a tuned Ace header car, because it's not "actually there"; its only there under a certain set of conditions.

This and a flex fuel kit would totally revive my love for this car lol
I need to start saving my pennies.

There's something like that on the Nameless dynos as well - I wonder if it's a similar cause.

Even if it's actually there, it's not something that's ever been obvious while driving.

I might have gone a different route if this setup had been available when I ordered parts... tough sell to switch now - though getting the car quieter may still push me along! It's a bit rough on the ears on road-trips right now. Need to get the suspension sorted first though.

Ok, thanks for the anomoly part. The other part doesnt really matter then but now is more out of curiousity

when I say more I don't mean raw numbers but mean sacraficing a smaller HP gain for more TQ or vice versa.
I guess what I was trying to say was what is a bigger benefit in terms of real world, more HP or more TQ?

From my understanding HP equals speed which is great on straights. But say a technical track (aka AutoX) where there is a lot of turns and decel/accel happening would more TQ equal faster times?

edit: I guess the simple way to word this would be am I correct in thinking of HP as how fast I could go and TQ as how fast I can reach that speed?

Yeah that's pretty much right.

Keep RPM's in the power band, 5k>

HP and TQ are forever intertwined. The two numbers relative to each other tell you a lil something about the power band but to get the full picture you need to look at the dyno graph. For autocross I would recommend the ACE350 or the 400/410.

The best advice I can give you is to run the stock muffler, or possibly the upcoming CSG "quiet" catback.

It depends purely on what part of the powerband you're in. Ultimately, Area Under the Curve (AUC) for the part of the powerband you use is what matters.

This is why a Turbo car with a torque spike that tapers hard, is faster than a linear powerband NA car with the same peak power; the turbo car has more AUC.

What is the quiet catback going to run?

I assume this is different than than the ACE 'quiet muffler' paired with the ACE header?

Not Sure, I have the ACE Header/ Front pipe combo now and with the 3" Perrin catback it was a bit too much:sigh:

Then how about one that is most mentioned when asked for quiet one - Q300?
Seeing how well ace header performed i have no doubts for their catback to be exemplary to reach it's design goals .. except that who knows when it will hit the market :/
