Thats one badass subie

[@HeidiFegles]

I bet this car is an absolute turd till 4400 rpm then light switch to monster.

[@colton251369]

I love the sound of that wastegate. Turbo smart?

[@yamahaSHO]

TiAL 44mm.

[@bm717252]

@@yamahaSHO do you also have a 3 or 4 port boost control solenoid for boost control? I hear your wastegate fluttering every time you get into boost?

[@yamahaSHO]

Probably a 3-port. This is a customer car.

[@jdm_jord0391]

@@bm717252 reason for the “wastegate flutter” is UEL headers on the Subarus! Gives them a pulsing sound! If you have a minute look up Subaru EL headers EWG and UEL headers EWG! You’ll hear a massive difference 😁

@@jdm_jord0391 ahhh ok 👍

When does boost come in?

[@yamahaSHO]

It's been a couple years since I tuned this car. Looking at the dyno graph, it was probably around 5,000 RPM to hit full boost.

[@JTRshuffleboy]

What are your mods for this wrx?

[@yamahaSHO]

I've posted this on my Facebook business page "jaz tuning". The owner has been tagged there and he can answer your questions.

[@chapmanmerchant]

dyno dyamic number lol

[@yamahaSHO]

At least get your dyno right if your going to ignore the racing results. Lulz...

[@aricgangar2512]

whats the exhaust set up from the header and downpipe

[@yamahaSHO]

You'll have to direct that question to "b_random_sti" on Instagram. It's been years since I tuned the car.

[@NathanElcoate]

32PSI. Is that a 2L and what rpm was redline set to? Fuelling?

[@yamahaSHO]

2.5L. Please look at the dyno graph in the video.

[@NathanElcoate]

@@yamahaSHO 8500 for a 2.5 very impressive.

[@HeidiFegles]

They are going to 9500 now. They have so much data now from 7k-12k now from testing that it’s totally doable with the right turbo and tune. With valve springs and cams to use that rpm up there. Stoc cams are pointless going that high in rpm.

[@NathanElcoate]

@@HeidiFegles My 2L used to rev to 8/8500 but I'm playing safe with stock rev limit on my new 2.5 (cams, heads, turbo, bearings, etc). Plenty of power and great for a daily driver. Cams, heads and the 2.5L bottom end make a huge difference over the revvy 2L.

[@HeidiFegles]

@@NathanElcoate I agree I run a 100mm bore 2.58 liter. Stock stroke, it’s a torque monster. 8.9:1 comp pure rally cross build for sure

[@renebarun1904]

How much boost?

[@yamahaSHO]

32 PSI on the dyno, 36 at the roll races.

[@renebarun1904]

@@yamahaSHO so it’s 664whp @ 36 psi of boost?

[@yamahaSHO]

No, it made 664whp @ 32 PSI.
