Ok. So if in modern cars, you don't get any power gains from exhaust and intake anymore. How do you get easy(not necessarily cheap) power?
natural aspiration or boosted application?
>>27836697NA
SON WHAT YOU NEED IS A SUPERCHARGER
>>27836709Add boost
>>27836709like >>27836727 said, add boost. you’re going to spend copious amounts of money to get minimal gains while NA. what engine is it?
>>27836693>you don't get any power gains from exhaust and intake anymore.You can from exhaust, intake is very well optimized, exhaust is usually standardized to lower costs on a lineup of engines.
>>27836693have some nerd crank up the timing with his laptop.
>>27836693chiptuning doodalso stripping entire car for weight loss.>not necessarily cheaphave someone else tune the car for you
Remove the cat. It's the only option on most modern cars without boost or a tune.
Chip tuneBigger turbo
>>27836709CAI+cat-back exhaust+tuneUsually nets you about 10% to 15% through the rev range. If you're not a wrenchlet I would suggest bigger throttle body+porting the head.
>>27836727DIY turbocharging is anything but easy.
> +100 HP for changing out one partIt would appear my superiority has led to controversy
>>27836693Stage II weight reduction
>>27836828>How do you get easy(not necessarily cheap) power?>Just rebuild the top end of your car.
>>27836731also all the cats and smog shit designs like cats used as a merge collecter right next to the block.removing or relocating cats on a modern smog designed engine frees up a good chunk of power.
>>27836822Supercharging can be.
>>27836856Not everyone got suckered into timing belts and 4 camshafts. Are you upset 2 valves and a bump stick can make big power?
>>27836828>one part>several parts in picture
>>27836693False premise.
>>27836693buy a faster car
>>27836856Lmao fucking wrenchlets
>>27836816I wish this meme would die.No modern engine is getting 10% power from some pipes and a flash unless it is an intentionally downtuned manufacturer variant or in the case of decreasing reliability by turning up the turbo settings.Yes I said that last part for anyone dumb enough to think I dont know electronically controlled turbo engines can be slammed with +5-8PSI.
>>27837325>explicitly references good, basic, and relatively reliable upgrades for a naturally aspirated engine >starts sperging out about muh boost at least read the quote chain you moron. CAI, exhaust, high flow cats and a tune always produce a decent bump in power for us NA slowfags. my shitbox got a 10% bump from a tune alone
>>27836693>Ok. So if in modern cars, you don't get any power gains from exhaust and intake anymore.>bolt-on gen III coyote makes 500whpU wot?
>>27836693Buy electric
>>27837348You're a fucking idiot.
>>27836877Not really. Most engines don't like goint from NA to any form of forced induction.
>>27837325Never post again. Go read a book, touch some wrenches, work on your car.
>>27837609lmao that all you got?
>>27836693higher lift cams and intakes. a lot of intakes are selected for a balance of torque and horsepower, so if you just wanted top end you could actually change the intake. if it’s not already running premium gas you could add a few degrees of timing advance
>>27836828Putting a more aggressive cam won't do shit unless you throw in good headers, exhaust, etc. You're for sure not getting an extra 100hp unless the engine is very down tuned already and you throw in a cam that makes nothing under 3000rpm. The ls2 in my gto has an aggressive cam, upgraded lifters, longtube headers, no cats, etc and its definitely not making 500hp. You need head work and better pistons to get that compression ratio up before you can really push out good numbers n/a. A cam mostly changes your power curve vs actually adding a ton of power. The cam that makes the most power is gonna take away your bottom end and might not make your car much faster unless you don't need the torque
Get a non weeblet 4 cylinder shitbox car
>>27836693more power for what? another 2hp driving to the grocery store?
>>27837620Incorrect.>>27837914You do not prove me wrong.
>>27837325Those are the retards I share a board with.
>>27838139I gotta set a new record at the burger King drive-through
>>27836693>in modern cars, you don't get any power gains from exhaust and intake anymoreyou do lol, modern cars are very choked by emissions, on turbo engines you can get over 50hp by just installing performance downpipes, on na cars a decat exhaust is also worth a lot. You actually can get more than ever with exhaust mods on a modern car. And thats not to mention the weight savings, factory exhausts weigh a lot
>>27836828what >>27838024 saidcams just move the power band around, for a daily especially in heavy traffic, lots of low end torque is great
>>27838139Are you an ai or a npc?
>>27838160>spews nonsense with no proof>specific nonsense about turbos when previously discussing na engines>no u when called outburden of proof is on you, my nigger. anyone with half a brain can go look up dyno runs on before/after tunes and other mods, so it's your turn to show how they actually don't do shit
>>27838776>dyno runsLmao. Try to find a non-fucked-with accurate before after dyno run. We got people claiming an intake pipe and 93 octane can make a stock Pentastar do 330 wheel. And you believe it.Fucking retarded you're not getting +55hp on a yote from pipes and timing advance maxxing.
>>27838904also depends on what kind of dyno it was.
>>27836693real answer incoming: ethanol plus a tune. you can run way more timing without knock, and you don't have to stress about high IATs. also allows you to go wild with cams. if you have the ability rebuild it you can throw diesel tier compression at it too. or if you already have a high comp engine that isn't inherently boost friendly, you can boost it with no worries.
>>27836693Depending on the vehicle, tuning. Some cars left power on the table just due to emissions programmed into the Fuel/Air ratios. Even better when you slap on the intake and exhaust and have it tuned afterwards.
>>27837394>bolt on>"bolt on">manufacturer upgraded intake manifold>a noted decrease in peak torque>requires a retune>bolt onYou kids are. Stupid.
>ya put the poop in the pipe
>>27838139>Trombone cope >Either a cuck or retard>Its probably bait.>Probably>4H20
>>27837614They don't have to
>>27839990They kinda do if you don't feel like rebuilding it every other pull.
>>27837325Modern turbo engines are 100% getting a 10% increase in power by replacing the restricted stock exhaust with a decat free flowing pipe. Cars made in the last couple of years in Europe / UK have to comply to harsh emissions standards which means loads of shit in the exhaust.
>>27840151you don't have to cram 60 psi into it yknow, a supercharger providing like 8 or 9 will already be a solid bump in power
>>27840151Modern turbocharging is easier than ever for most performance platforms. Pretty much everyone makes a boost friendly engine architecture at this point. And 20psi is enough to double hp in most cars anyway.
>>27841050What the fuck engine do you think can take 20 pounds of boost without needing any major work done?
>>27841037A supercharger running 8 psi is basically nothing and it still requires a lot of work to pull of. Zoomers been playing to much NFS and watching too many goytubers doing shitty builds for views.
>>27837325Isn't the biggest meme in the BMW community right now "it's got a downpipe and a tune"? They're getting almost double the horsepower.
>>27836693Remove the CAT for a free 5-15hp. You can even make money doing this depending on the car kek
>>27841443And shredding bearings by 45k miles doing so.Though my point was already made in the post
>>27841435Enjoy dead engine I guess
>>27839759>implying an intake manifold doesn't bolt on to the cylinder heads>implying plugging in a tuner is hard>implying either entails opening up the motorRetard, plz.
>>27836709cams. you need revs to make na power
>>27837325(You) can google dyno graphs of stock vs CAI + exhaust and see exactly thatYou're not gonna see any big gains on a 2L i4 from a CAI and exhaust but on engines where emissions cuck them more, ie V8s, you're gonna see the 10-15% gains.https://www.youtube.com/watch?v=Sy3PXAsnTL0>inb4 muh tuner shop fudging numbers so people will pay post proofs of the opposite then retard
What if there was a tiny windmill in the exhaust to generate some electricity?
>>27843457what if you hooked the axle of the tiny windmill to a vacuum on the intake that would suck in more air?
>>27843452>CAI +5% peak hp and +4% max tqthe headers and cat were the only thing that did anything significant, the CAI was marginal and literally everything else did nothing except maybe trade a little bit of low end power/tq for higher end power/tq if anything. it's also curious the throttle body graph starts at 3k. seems to give credence to the idea that too big of pipes can cause losses at lower RPMs. given that most of the time when people say their car has "exhaust" they're talking about a cat-back system, I'm gonna say the other anon was basically right. if you have a 5.0 mustang, don't bother with bolt ons and a tune unless you're getting headers.
