Stock is 200hp
If I put supercharger in it with everything else stock how much hp increase?
What is the best HP area for performance and also reliability. 260-300?
there are some superchargers that make more than 250 hp and wont void warranty, google them
About tree fiddy.
The Jackson Racing supercharger with the CARB legal tune is supposed to be very reliable, and that'll put you at ~280whp.
Beyond 300whp reliability of the engine and transmission gets iffy.
>12:1 compression ratio
>If I put supercharger in it with everything else stock
>>14026168
The car makes 177 whp, how the fuck is a super charger going to make 123 whp? No just no. Maybe 250 whp
>>14026173
Dude it's all about the tune, learned that in the last thread. A sick stage 3 tune can defy the laws of physics no problem
>>14026173
You're right dude he needs an engine with at least 2.5:1 compression ratio to supercharge it XDD
>>14026191
what is better is like 8:1 compression.
>>14026191
nice hyperbole, slut.
>>14026198
Yeah, and you definitely shouldn't supercharge any engine that isn't 8:1.
>>14026173
anon you are going to trigger that dumb amerikek trip..
>>14026187
oh no
>>14026191
>not understanding how high compression negatively affects forced induction
I'd like to see a dyno of this car stock making 200. Most sit around ~165-175
>>14026133
God dammit you got my hopes up with that title and image you faggot
>>14026224
Not trolling, but if you add a thicker head gasket, wouldn't that increase piston travel and thus, reduce the compression?
>>14026309
It wouldn't increase piston travel/stroke, but it would increase the space between the piston and head, slightly lowering the compression.
>>14026338
This is correct.
>>14026198
Holy fuck you guys are ignorant. You want as much compression as you can get that's still within a reasonable (let's say 20%) detonation margin. Going from a motor with 12:1 compression to 8:1 would only make sense if you were running like 18 - 24 lbs of boost. I mean seriously just go do the math. If he will only be getting 8psi from that supercharger them I bet he could just pull some timing, running higher octane/e85 if he really wanted to. It's amazing what you can get by with running aftermarket ECU these days.
JUST
>>14026338
Don't do that. You will change your quench zones in the combustion chamber and could possibly create even more detonation.
Unless you absolutely have to, don't run a thicker head gasket.
>>14026417
you cant just run more aggressive timing and put higher octane when you are doing forced induction dude
You just have to retard the timing in the tune bro. Timing already retarded beyond TDC? Just retard it more. Getting pre-ignition? Don't worry retarding the timing will fix it.
>>14026442
He's saying to drop the timing, not increase it. And yes, putting as little as 7-8 lbs of boost is easy to do with his steps, though it would be highly recommended to get an intercooler.
>>14026466
stop posting anytime
>>14026469
Exactly. Superchargers like the Jackson systems aren't some monster of a compressor. If he were going turbo, I would say sure crack open the block and lower the compression just so he has room to play with for the future without having to open the block again, but dropping 4 whole numbers of compression for a supercharger is crazy lol, your just wasting your time. I don't even think they make superchargers that could fill that compression void on a DC-45 motor.
>>14026503
I doubt you could make enough boost to fill in that huge octane void from the lowered compression. I'm not much of a supercharger kind of guy due to how difficult it is to make more power than you already have out of it, while a turbo's waste gate can be easily adjusted. Though supercharging is usually much cheaper and fills most people's needs for power gainz.
>>14026180
It depends on the fuel and dyno. I've seen high 180's to the wheel so 200 @ the crank (where the OEM dyno tests the engine) is legit. You can lose a whole ten hp just by using 89 octane.
>>14026173
>not knowing about the edlebrock supercharger for the twins
Vortech supercharger with a conservative tune is what you want. Only requirement is aftermarket oil cooler, stock clutch holds up well. You can expect about 250whp reliably
>>14026734
>clutch
mines an automatic
got it for 7000 lol so im not gonna complain
will a supercharger in an auto be less reliable then a manual
>>14027122
The Aisin box in the twins is the same as the IS250, and those don't have much more power. Not sure what else it's been used in, or how many people have bothered to FI their automatic GT86.
>>14027122
should have sold it for double what you got it for and got a real (i.e. not underpowered) car
>>14027122
>automatic
>7 grand
did you buy a salvage title?
>>14026570
So why is it that all the stock dynos of the FR-S show mid 160s?
>>14026417
>Going from a motor with 12:1 compression to 8:1 would only make sense if you were running like 18 - 24 lbs of boost.
More like 30+.
A stage IV tune will get it to 360+
>>14026157
No there aren't. Go show me where on the Toyota / Subaru site they list them as not voiding your warranty.
>>14028121

The Edlebrock supercharger is completely bolt-on, 50 state CARB legal, and makes roughly 250rwhp.
It also provides a 3 year, 30,000 power train warranty from edlebrock.
You could always uninstall the supercharger if you ever had to bring the car into the dealer
>>14026180
People will sometimes double the stock hp with superchargers. Its very possible to gain that much hp from a good supercharger.
>>14028760
You think a 3 year 30000 warranty from a third party is the same as not voiding your 5 year 100000 warranty from a manufacturer? You are also planning to remove the entire kit every time it goes to a dealer?
>>14028836
I'm not the the one who said that the supercharger retains the factory warranty, but honestly, I would prefer taking my car to edlebrock instead of some random Scion dealer.
>>14028989
Also, most people who modify their car don't really care about the factory warranty, especially those considering forced induction
>>14026187
>Quantifying a tune based on arbitrary "stages"
KEK
>>14028774
>Double
Yeah no, not gonna happen. You have the parastic drag first off, 2nd just fucking no.
Christ the jump in an ej impreza from na to fi is only 50 horse and 70 foot pounds with the td04
>>14029059
Subaru does have quantifiable stage levels though.
>>14029059
you didn't get the sarcasm in his post?
>>14026187
>Heartbreaker proving yet again he only kind of knows how things work
>>14028836
Dealers have to prove in court of law that your mod caused the failure if they want to dishonor their warranty. I don't think any factory warranties explicitly forbid mods.
>>14029116
Ok...
>>14029130
>>14029049
>>14028836
I'm pretty sure a $7000 brz doesn't have a warranty anymore
>>14029130
Not really, they can deny warranty on most parts for any aftermarket part reason. However, you are protected in that not all dealers are pieces of shit and won't try to claim that your intercooler caused your cv axle seals to start leaking.
Also, you can't just void your warranty by installing aftermarket parts as long as they don't directly cause the issue you're having. This is up to the dealerships discretion however...
>>14029135
Wow, you can run straight e85 without adding an additional injector?
>>14029130
>dealers have to prove
Stopped right there, you are spewing nonsense, Toyota provides the warranties, even for the used program, not the dealer.
>>14029116
what the fuck are you on about? cosworth offer a 270hp blower kit that you can wind up to 400hp on pump fuel if you lower the compression
>>14029178
no, that will have uprated injectors
>>14029116
>ej impreza from na to fi is only 50 horse and 70 foot pounds with the td04
And why does this mean a big supercharger couldnt add double? Because some small turbocharger that is 100% irrelevant to superchargers "only adds 50hp"? I dont think you fully understand how this works.
Why cant anybody on /o/ into forced induction? FI isnt 2 dimensional like people on/o/ think.
>>14029243
Op refers to putting on a supercharger.
This means bolt on, no fuel mods, no lower compression.
No fucking naturally aspirated engines can take mountains of boost on pump gas
>>14029394
from op:
>Stock is 200hp
>If I put supercharger in it with everything else stock how much hp increase?
>What is the best HP area for performance and also reliability. 260-300?
A stock frs with an e-force supercharger makes 250rwhp on 91 octane. Tuned with 93 octane will easily get you 260hp without any changes to the engine or fuel delivery system
>>14029557
That's not double.
>>14028121
different dynos read different
a stock frs on my local mustang dyno would be like 145-150whp. The dynojet a few cities over would say 180whp
>>14029998
I never said it was. Besides, who honestly bolts on a supercharger without changing things like fuel injectors or exhaust? It's not like those are major mods, and with bolt ons, the eforce and the right tune you will be close to doubling horsepower.
It's not like people throw on turbochargers with no supporting mods.
>>14030049
That was what I was arguing against, if you actually followed the posts.
See
>>14029116
Also like I said in>>14029394
No na engine with a high comp ratio is gonna take enough boost to do what half the fucks in this thread are taking about.
>>14030091
???
You don't need to lower compression to double hp in a 86 though
>>14030114
you do if you don't want your engine to be a ticking bomb
>>14026439
Quench is less of an issue with forced induction. Quench plays a much larger role in NA applications. Not saying having a proper quench isn't the right thing here but he's talking about adding a blower to a flat 4. Quench wont mean a damn thing.
>>14028736
No shit, but someone was claiming 180 at the wheels.
>>14028753
Yeah, they're dynos known for reporting high compared to Mustang and Dyno Dynamics.
>>14030136
Go visit the forums if you want proof. Plenty of good data there suggesting otherwise.
>>14030246
>done 10,000miles on my supercharger and only replaced head gaskets twice
>runs like a champ
>bilt not bawt
>>14030091
Tons can. F20C, KA24, B18, K20, LS, VQ37, 2JZ, VH45, UZ, VG30E, the list goes on. Its dumb to say so and so engine cant be turbo because of its CR. If you tune it right it will do fine. It may make it harder to turbo than a comparable lower compression engine, but far from impissible
>>14030256
It's obvious that you have no idea what you're talking about.
