My friend let me give you some advice that works for me. If you talk about something to the point friends, girlfriend, family are tired of hearing about it. You will buy it.
Shoot, I have a build on Gran Turismo 7 with stage 3 weight reduction, race exhaust, headers, air intake, slotted rotors, 17" wheels and she weighs 2183lbs. With those bolts ons in addition to a custom mapped ECU, and a custom rear diff (currently close to stock settings), she's outputting 269HP to the crank @7500rpms and 205lbs of torque at 4600rpms. All with a completely stock motor! She already feels like a rocket ship 😆. Can't wait to see how me moves when I fine tune the gearing and rear diff. Adding engine upgrades is last on my list as I'll have to stiffen up the chassis to prevent twisting which will add more weight in addition to beefier tires. Will probably want to add a front splitter too. Ahhh, I love tweaking things. Can't wait for the day I can roll off the lot with one of my own. 🤩
@@787blah If I were to aim toward being that light I'd. Completely gut the car down to the chassis and weight that. Depending on what it weighed from there would determine if I wanted to go further than that, highly doubt it other than swapping out the exhaust. But since it'd be a dedicated track car at that point, might as well go ahead and strip the engine bay down while all of the wiring is exposed and remove all of the unnecessary bits (Windshield washer, A/C, Heating unit, wiring harness, wires) and rebuild the harness. Seats, light weight battery, engine components, pulleys, wheels/tires. Replace the windows with poly and if the budget allowed, lastly would be to start replacing body panels with carbon fiber. Realistically though I'd want to retain most of the cars base functionality so I'd just gut it, rebuild the wiring harness, replace the windows, throw an aero kit on it, add fully covered underbody panels and call it a day. From the manufacturing line the engineers already lightened up the materials of the roof of the car and the hood is made out of aluminum so there's not too much more weight to shave off unless you want to replace the roof entirely. As I performed engine upgrades overtime, I'd replace components with their counterparts.
Amen to that brother. Quite a few good companies make fantastic unequal length performance headers these days too. The difference between the two isn't nearly significant enough to justify not having that sweet boxer rumble.
Definitely considering this. Needs to have proven reliability for me to spend the roughly $9k when it's all said and done. Burnt Orange would be a beautiful on the manifold.
Yeah these motors are trash. Why would Toyota even partner with Subaru for a motor. They aren’t known for reliability. 9k for 300 wheel is crap even reliably.
@gsxMac24 no traction either unless much wider wheels are used with better differential and clutch, so fourth. Just more power would lead to a crash easily.
I will definitely consider one... after my powertrain warranty has expired and the reliability of the FA24 on boost has been determined from the data. ... but yes, I do want 300 whp please.
I will consider mine after you implement one on your engine and validate its capabilities with boost. Please leave a comment after and after. Thanks in advance. 😂
Had my 2023 BRZ back from HARROP for two weeks now. Given all the funds I've thrown at race engines and gear for various track cars over many years the money spent with HARROP for the S/C plus install is hands down the best investment yet. The enhancement is next level: fitment. looks and above all performance. These guys simply know their stuff. Very much appreciated.
My gr86 NEEDS this kind of boost. The tune alone costs over $1200 though. So it's hard to justify spending around 8 grand for the power. But, maybe in a year or two.
The only benefit to running that style of Intercooler is being able to sit on launch control and not heat-soak or run a killer chiller. A proper top-mount or FMI is just as good in ALMOST all cases without having to worry about the pump failing/malfunctioning, since it's not factory. Not saying it wouldn't be unique tho 👍
That supercharger looks good, fits in there nicely, makes good power, and sounds good to.. really nice job 👍 I wonder who will be the first to take the turbo 2.4 block out of a WRX. Could prob make 400 hp
Any plans to design a supercharger kit for an Evo 8/9 and an older STi 2008 - 2014? Would be cool to do something different in that supercharger setup is so clean.
Have you guys incorporated some of these improvements from the GR supercharger to the kit for the GT supercharger? Also, what is the weight of the kit? You guys do great work. Thank you.
@@Username-2 they eventually fixed those, I think, after a few years, except for when Subaru STI's became Toyota's in like 2010. The like 2010 -2014 models. You would think when you have a good 2.5 engine, just leave it alone.
What's the weight of it? Can we get some more videos of the track car running it please. Is the price in the AU site reduced (minus tax) for export orders?
@@mogulme6190 What are you talking about? The Supra 4cylinder 2.0 engine is rated at 255hp from the factory, and it usually dyno at 280hp on the same type of dynamometer as this BRZ, I am comparing them on the same field as far as horsepower rating goes.
In my opinion this is a necessary upgrade to make this car satisfactory. Yet that engine is not going to last long now. If your going to spend another 9k, and know you will be rebuilding your engine soon. Why not just buy a better car in the first place?
Modern tech is crazy. Look at Mazda's Skyactiv X, which can go into a "diesel" type mode that ignites the gasoline with no spark, just compression. In that configuration, the engine has a compression ratio of 16:1, on Regular octane gasoline.
@@bttawfiq Of course! To give a more precise reason, it’s mostly timing trickery for most new engines, among other improvements such as direct injection. The FA24 in the BRZ/GR86 specifically knocks constantly, by design. The computer relies on the knock sensors to pull timing through VVT in situations where you have bad fuel or it’s at the very top of the rev range. For this reason, you can actually run regular fuel in “premium only” vehicles without damaging anything, it’ll just cut 30% of the power or thereabouts. Mazda’s system is more advanced than Subaru, so the owner’s manual for the BRZ says that you may use 87 octane in an emergency, but do not rev it all the way out. Mazda on the other hand says that you may run 87, but expect a sizable decrease in power. If you’d like more power with forced induction on modern vehicles, you may run race fuel or more commonly E85 and tune for that, with an increase in power without changing compression ratio or boost, since the knock sensors won’t retard timing with those fuels.
@@haifai3916 I do understand how it works, but thanks for the explanation nonetheless. I used to own a 2013 Jeep Grand Cherokee SRT8, that engine knocked like crazy in very hot weather and 91 Octane fuel barely satisfied it, I used to add a few liters of 109 Octane race fuel to each tank fill up, worked like a charm. When I researched it it appears the engine management in Hemis aren't good in timing manipulation, and it had a 10.9:1 compression ratio.
You would need an oil cooler and catch cans at the bare minimum imo to be “reliable” on track. It’s not a turn key track car from the factory at $30K usd. Maybe even a 1L overfill on the oil., or an accusump if it would fit with the Supercharger on.
That pulley seems way too big? Is there an option for 80mm and 12psi. Along with injectors and valve springs, of course exhaust, should make significantly more power. This will still seem slow?? As in buy the Subaru ts model with all the chassis mods stock, then add this for power, albeit not enough still

The tune alone costs over $1200 though. So it's hard to justify spending around 8 grand for the power. But, maybe in a year or two.
That should be around 320hp to the crank. At 2835 lbs that gives it almost exactly the same power-to-weight ratio of the Nissan Z, nice 👍🏻
A car this light, supercharged must be a blast to drive!
If I ever have to replace my current Cosworth supercharged GT86, this will be the kit I will go for for the GR86. Very nicely done guys.
Yes.
Curious about an EJ manifold with the integrated intercoolers, is this a product that makes sense to prototype?

What's the total weight of this kit?
Did somebody say CARB EO???? 👀
cali boys rise up
Is this supercharger kit suitable for an auto
Did they underrate the GR86/BRZ's power?
If it's showing 215 at the wheels its more like 250 bhp at the crank rather than the advertised 231 bhp
Lets just agree to call these cars the GRZ. It just makes sense.
Great power. Can the internals take it reliably?
Considering they can barely take stock power reliably, I doubt it. It’s a Subaru engine.
My old FA20 ran 10 PSI of (turbo) boost for a decade, stock. Tune smart and treat it well; this much power will be fine.
The engine will be fine, but after 100,000mi the head gaskets will go, but that's practically every single NA Subaru engine

Whats the longevity of the engine when a supercharge is installed
Do you need to upgrade the stock clutch and pressure plate when installing this kit?
Lmao it just went from dying at 60k to 30k 😂
this looks amazing
YES FINALLY!!
Does it have rev hang issues when rev match down shifting?
The stock car doesn’t have that issue why would the tuned supercharger kit?
@tone3560 Neither does the Miata stock, but Supercharger installs have been known to create that issue on that platform. It's not a dumb question.
Can you guys make a SC for the 1MZ-FE. Plenty of us still around! haha
How much is the price ? And in what condition can I get my car to do this?
Man, when is this going to be available? It has been out of stock for months
Please can you provide details on the exhaust you have for this setup
They said exhaust is all stock.
Can this work with the PERRIN Cold Air Intake? Or will I have to put my stock air intake back on?
300whp in a small rwd car must be so fun
Is the racecar running on e-85 and or plus methanol. I can't imagine it possible on pump fuel alone even with a built block to turn it up....?
303HP at 2900lb, should be running with the 4cyl Supra, 4.8 0-60 and 13.5 quarter mile, for less cash.

Are custom colors an option?
Ok dumb question, why does this FA24 running 8psi make more power than the FA24 running 14 PSI in the WRX?
I would guess it has higher compression?
Much higher compression ratio on the FA24.
Old engine
Would you guys recommend a 2.5 inch or 3 inch exhaust for this on a road setup?
With a supercharger, bigger is always better
Unless you run dual 2.5 out of each bank of cylinders all yhe way. That would be amazing
I want one.
Have you tested the engine for its reliability beyond 50,000 kms of supercharger time. Boxers have a bad rep for engine life
50k km is about the longest I would expect the engine to last after this upgrade. Too many engines failing on stock power.
Call me old school, but how is it possible to supercharge an engine with 12.5:1 compression ratio? And without using race fuel?
