All-New 2022 Subaru BRZ Makes Global Debut

I want to see the new exhaust manifold. I can’t get over how different it sounds.

It'll be great for sure

The general rule of thumb is if you have full bolt on with a tune on pump gas, you can make the same whp as the stock bhp. E85 will add extra. People were making 215whp on the first gen on E85.This 2nd Gen will easily make 250whp on E85 with fbo.

People are even making 200 whp STOCK on E85.

That's all technical though, the experience and joy of doing it isn't worth the effort more than a couple times.

You could theoretically up the redline by a just a bit in the tune if it were important to get to 60 in 2nd.

Yeah, the autox guys seem to find a spare 400-600RPM useful, but then again they also need more frequent engine replacements. I'm just glad it's not like some cost-cutting designs where valve float starts just above redline. Makes me think the stock tune has padding for those of us who occasionally misjudge how close to redline their next downshift will put them

Other than that not much.

Ah. So might be zero change.

Yep depending on if they use their definition or the real one.

Probably more to do with the larger displacement than the header.
Bigger displacement = lower tone and rumble.

General rule of thumb? With these cars specifically? Because so many different cars have different drivetrain and pumping losses, it's near impossible to say something like that and have it encompass more than one engine/chassis combo.

From a logical standpoint, I think it's more accurate to suggest that you can gain 20% more power from bolts ons and a tune on pump gas. We don't know how well this engine will react to the properties of e85. You'd think that you have a significant amount of headroom, but sometimes headroom for knock isn't your bottleneck.

I'm excited to see, regardless; it'll be a cool new adventure and we won't already have the answers! People can buy frontpipes and intakes, who knows what mysteries they'll unravel. New intake manifold, header designs, ITBs, plenum spacers... It's like seeing the world for the first time all over again! Maybe.

I think to say 20% is even to0 specific when talking about these cars. The better term would probably be up to 20%.All depends on the bolt ons and how well it is tuned for them.
Some cars are really easy to bump up with some bolt ons. Back in my Lancer day you could easily get 30 or even 40% with a decent CAI and header with a tune to address them and run higher octane fuel.
The Twins (Quads?) already have many of the things that you would normally change out to get easy gains so it is a bit rougher to get even small increases. This is a true testament to how much work they put into the engine in the first place.

I think the 24 will rock people's worlds with just a flexfuel tune and some corn! Those that can't get E85 are going to have a harder time getting much out of it though no matter how many bolt ons they throw at it.

Once I figured it out, it was easy to remember: a Premium that isn't premium, and a Limited that isn't limited.

A lot of these cars are hitting 15-20% loss from crank, so in general they will gain towards their bhp at the wheels. I've followed enough platforms to see this and in general, full header back exhaust on pump gas will put you in gains to the wheel where stock BHP is for NA cars. a 5.0 Coyote will put you at 460whp with intake and exhaust mods and tunes. The VQ35HR will put you at 300whp. FA20 will put you at around 200whp. My buddy had a swapped k20 with 225whp in his civic. Another one had a bolt on K20 in his RSX Type S with the same power. The Camaro LT1 will make 450whp with a bolt on and tune. A FBO E92 M3 will make near 414whp with FBO and etc. So I think it's safe to say Gen 2 FRS will make ~250whp with e85.

That's mostly true with a short runner catted header and a circa 2010-2017 design where heavily rich mixtures are used to control EGT. You won't be able to find as much power if there aren't cats to delete, or with an integrated header that can't be replaced. Higher combustion speed for efficiency is also now a strong emphasis in design, and as a result there's much less power to pick up at the top end by leaning out AFR.

If you care about being smog legal, the FA20's main cats are the ones in the header, and can't be removed.

The good news about this 2.4 is that with a 13.5 compression ratio, you can probably safely bet that with a bit of E85 mixed in the tank, a bit of timing advance will pick up noticeable power. 240hp on 95 R+M/2 fuel is my guess.
