FA20CLUB: Unequal Length Header NA & Turbo Compatable - Page 7 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

looks awesome, but i have to wonder how many people are going to want an unequal length header if they're going turbo. doesn't that have quite an adverse effect vs. equal length? i would think the turbo guys would be more interested in performance, since all you can hear is the turbo anyway lol.

you still get the the sound even with the turbo. i can hear it avo kits. its not as dominant as when the engine is NA but its still there

sounds nice

. i wonder what the actual difference between equal and unequal length is on a turbo car performance-wise. maybe now that fa20club makes this we can find out eventually. i think it'll be 5-10whp peak at most.

Yeah, it depends on power level. I've seen STI's on the 400+ whp range be between 10-20.

I've seen 300+ whp cars to be more on the 10 or less range. We should find out soon enough!

Won't it also affect turbo spooling characteristics?

FA20Club.com · 07-05-2013, 12:26 AM

pretty much. i prefer not to speculate just build it install it dyno test it end of discussion.

Jtymay92 · 07-05-2013, 04:52 PM

Is this going on the dyno today?

jflogerzi · 07-05-2013, 05:36 PM

I can't wait for results. I have narrowed my choices down between 3 option for a header:

JDL UEL
FA20Club UEL
FAC20Club EL

i got the baseline on my auto since its stock again will be on the dyno monday plan was yesterday but we had a walk-in that i had to take care of. but we will have the stock vs header only results monday. i will not be tuning it on the stock setup. i will only be tuning on the manual with our muffler delete , over pipe, cai intake and front pipe. those will be 93 octane results if i can run the fuel down over the week ill test e85 later.
