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.
