[pentaxshooter]

Yup, another of these threads. Awesome power

Here's a little teaser of Accelerated Performance's new turbo kit for the BRZ/FRS.
Stock Header, BRZ-400 Turbo Kit @ 20PSI, OMNI 4 BAR Map Sensor, DW65 Pump, DW900 Injectors, Exedy Clutch !

[Robski92]

Do want!

[TurboWraith]

That's pretty sweet. I hope this kind of thing really takes off, love the car. I would like to buy one in a few years.

[VikingVR6GTI]

Forgive my stupid question but how can it be the "stock header" if it wasn't turbo to begin with?

Turbo's are located on the 'up-pipe' on subaru's. Not on the 'header'.

[above8k]

Now they have ruined it with fking turbo...

[kevin FaKiN spLits]

In to see comments of how idiots would get a Mustang Boss now because its a "better option" for the money

This is very impressive. Wonder who will break the 500whp barrier first!

Do they mention internal work at all?

What are you talking about?

I'll take a fully warrantied and balanced Boss 302 over a ticking timebomb bottle rocket ****ty powerband 439WHP BRZ any day of the week. Thanks.

Stock internals.

Ah, I see. As I said...stupid question but now I know. Thanks!

Thanks, was wondering this too.

[kevin FaKiN spLits]

Balanced 302? Lol

[Shomegrown]

Balanced 302? Lol

Wanna know how I know you've never tried to drive a heavily boosted car on a racetrack?

TCL on a BRZ with previously-requested 'tons more power' - "ZOMG WHAT A POS IT WILL GUARANTEED ASPLODE!!!1one I WOULD MUCH RATHER HAVE ALL THE OTHER CARS!!!"

Sh*t powerband? Not sure if srs. This BRZ is faster in a straight line, isn't that all that matters?

So what's the new complaint about this car this time around? 8k rpm shift point too high, will dead?

[C4 A6]

Does 440whp @ 20 psi seem a little low to anyone?

[deucestudios]

When did you pick up the black beast?
That's a sexy machine right there...

[kevin FaKiN spLits]

Wanna know that I have. And it was fwd too. Will eat any Mustang you put in the pit with it.

Or dragstrip, where I've made a few passes in a buddies 600hp 1.8t.

[PowerDubs]

Does 440whp @ 20 psi seem a little low to anyone?

No.


In simplistic terms- 200hp at atmo + 15psi which roughly doubles atmo = 400 crank. Add another 5psi, roughly 70hp then subtract drivetrain loss from bhp to whp and 440whp sounds about right, if not a little optimistic.

[kevin FaKiN spLits]

Does 440whp @ 20 psi seem a little low to anyone?

No
It looks to be a GT3076, or something equivalent from a different company. I haven't even tried to look up the specs to this kit yet, I will soon

[SVTDanny]

Stock internals.

Not for long....

Boost pressure doesn't really mean much of anything without knowing other specifics.

I like the BRZ, I don't think boosting it to within an inch of meltdown will make the car better. You'll screw up much of what's good about the car. Goodbye to sharp throttle response and a linear powerband. It's already nose heavy, adding 50+ lbs of turbo hardware isn't going to help with that. And personally I can't imagine the powertrain of a lightweight 2700 lb car lasting too long with that kind of power.

Like I said, I'll take the car designed for 450 hp. And yes, I'm very sure the Boss's powerband is better for track duty.

[pentaxshooter]

I have my doubts Audi designed the S4 for ~500whp. Return your car back to stock or hush

Ok homeslice.

[AKADriver]

Not for long....

Yeah, not to be "that guy" but...

With the turbo hanging off the stock exhaust manifolds, and stock compression; this is dyno queen stuff, just to say they were first to do it. Not really usable; on a track it'd explode, and the turbo location to be compatible with the stock header is undoubtedly impeding boost response.

The newer turbo Subarus (starting with the current-gen Legacy GT and Forester diesel and eventually on the next WRX) don't use the old header/up-pipe configuration, they put the turbo down low and in front. Once people develop manifolds, this will be the desirable setup on this car too. There's just more room up there and shorter piping distances.

When I bought my S4 10 years ago, there weren't exactly many 500+ hp sedans on the market. So I built one instead.

But there's no doubt that a car with factory 500+ hp (CTS-V for example) is going to be an overall better vehicle in terms of balance and reliability than any tuner car with double the OEM power.

It most likely isn't an inch from meltdown. Noone has any idea of the failing point of the rods, or when the pistons will start to melt... Breaking limits need to be found. So far we're seeing close to 450hp out of a stock motor. 20 psi isn't absolutely crazy either...

Relocate the battery to the trunk, and there you go relieve some weight off that super heavy front end

What car is exactly designed for 450hp? With a good driver this BRZ would own the 302 on a road course you know that..

*yawn*

Let me know when someone runs that setup for 100k miles.

Subaru engines which are designed for boost are likely to pop at that power level. You expect one that's not designed for boost to fare better? LOL.

Said with the patented TCL Hyperbole..

Almost as idiotic as comparing a fully productionized vehicle to a one-off custom job

[6cylVWguy]

This sounds about right. The powerband on the dyno looks pretty smooth and linear until about 4500 rpms where things then start to go all over the place. This might be ok on a road course with a lot of straightaways without any sharp turns, but on anything really technical and tight, it wouldn't be all that fun.

Having said that, it's fun to see how much power people can get out of these cars, but personally, I think 250 whp would be perfect in a car like this.

[GiacGtiAgain]

Does 440whp @ 20 psi seem a little low to anyone?

um no, since psi is an arbitrary number if we don't have a flow chart for the turbo. i'd argue it sounds borderline high depending on the turbo they used. this is WELL over double the stock horsepower.

[SchnellFowVay]

Here we go again. The Toyobaru is ruining the Car Lounge.

Can we all just agree that if Subaru releases a naturally aspired 240-260hp version of the BRZ with a screaming redline, at a $30k-32k, that it will finally be a universally cool car?
