HKS SRI Intake Kit

[rabbito]

i had Simota SRI which had heat shield looking thing...sound like a boat when im on full throttle and gain was alright..i also lost slight low torque and the sound was horriffic...sounds like a boat crusing by..so i changed them back to K&N drop in...

im giving chance to HKS mushroom intake which also has inner velocity stack(when you take out the filter, you will see it)..i also like the fact that filter is facing towards opposite of the engine..

im going to give HKS a chance..just got it delivered so we will see what happens..🤔🤔🤔🤔🤔🤔🤔

the intake pipings custom made from the local shop..

btw im in asia, we use brand like HKS, Blitz more often here...http://uploads.tapatalk-cdn.com/20160914/d120d56480ab64a7e4ae2ee530a70a47.jpghttp://uploads.tapatalk-cdn.com/20160914/01f2c27696a311d76a723635bf2dcbf6.jpg

HKS makes some balling stuff. The couplers and the tube look high quality, but the HKS filters have a really really bad rep. I've had terrible experiences with them, I would switch it out for a higher quality cone filter if space permits.

i remember that hype(im from cali actually and remember that hks hype about filter sucked in or being dirty)...it was while ago(decade)..
they actually improved a lot after that incident where they lost shit load of money..theyre quality start getting better...in asia, majority of the shops use HKS...

the piping is not from HKS, its custom made...right now i got engine light turnt on...FML!!!! 😭😭😭😭😭😭
i got to check again in the morning...i will update....smh

i would go Apexi or Blitz for a good quality SRI. Apexi i believe has one of the best filtering cones.

I love my blitz SUS power core.

update: just finish reinstalling them...took off the battery and put them back on..start the engine for about 5 min..ecu automatically correct itself..its running 700-800rpm now...i dont know why but current intake and simota intake i had before have sluggish throttle response..(maybe due to sound)..?
i can notice the hp and tq gain but not a huge gain...maybe 4-5hp...i will test them on the highway tomorrow...

All in your head, you will be lucky to gain any gains but just cool sound.

Update: last night i test drove them and it was pretty good, great mid to high range...😎😎😎😎😎😎
morning i started the car and drove to coffee shop...i didnt notice any power gain, sound loud and heard some hissing noise..i just found out that stock vacum hose clamp was lose....fml...stock clamp cannot hold on to the hose during full throttle...because intake part is a fxxxing metal and it slips out...went to a shop and purchased myself couple intake clamps and zip ties...😣😣😣😣😣😣😣

[rabbito]

Update: finally comepleted...i bought the clamp and put them on tight(vacum hose..fml)...unplug the battery cable and put them back on...waited about 5 minutes for ecu to adjust rpms, running 700-800rpm...http://uploads.tapatalk-cdn.com/20160915/134ed866c1e148472e805f90933ac535.jpghttp://uploads.tapatalk-cdn.com/20160915/0d676b179dfbe6db8a8e3b931bb132b2.jpg

shop gave me 3 choices; hks, apexi or k&n....honestly....hks stands out in asia, theyre like the top brand out here..watch those jap GT Channels doing touge..lol

i used blitz sus power before on my rx7, lovely, easy to clean and easy to put them back on..

if its only a sound, whats the point of purchasing them?

Sound....louder "seems" to mean faster to a certain niche of people

It possibly could increase power somewhere on the powerband but doesn't necessarily mean that it will be usable or really beneficial.

Even in the GTR there isn't an OEM open filter setup...(http://www.driving.co.uk/s3/st-driving-prod/uploads/2014/10/nissan-gt-r-nismo-engine.jpg)

right now i have a full exhaust set up with polished TB with spacer...i think the intake is doing the job 😎
i dont know about just having intake though.. 🤔🤔

I'm not an expert by any stretch of the imagination, but my understanding (which makes sense to me) is that if you don't do the entire system the way you did - intake, manifold, cat, piping, muffler, etc. - then there really are no gains to be had. There's going to be a bottleneck somewhere.

I've been thinking about an intake for a long time, but I think I'm going to wait until I can do the entire system in one shot. I could be totally wrong, but it seems logical.

right now the intake sound is confusing me...i dont like it at all...i dont like vroom sound coming from engine bay...lol...😣😣😣😣
i see the gauge and its doing its job......
im seeing an issue though...a lot of air in and out..i need ecu with fuel control...i only have timing advance ecu...i bet pumping a little more fuel will solve this issue..

Do you have your own shop, or have a family member with a shop where you do all this work? You've mentioned doing your build on a budget, but I've seen you go through parts like people go through underwear lol. You've talked about piston work and I'm no mechanic, but messing with internals can't be cheap, eh?

more shops in asia...parts flies in from japan like crazy...labors cheaper(usually charge you with the parts)..cars expensive due to tax(my yaris was $22,000, suppose to have cheapest tax in the country due to engine being 1.5) but parts are affordable...in southeast asia, everybody comes to thailand to get the parts..
i buy 2nd hand parts shipped from japan or buy local brands because custom made are slightly cheaper..

As I said in my previous post, you won't be making much power with an intake. It is more of a noise thing than anything else. I understand that you have mods to your car, but I find it hard to believe that you are actually pushing more air in/out of your engine. What you are most likely doing with your current intake/exhaust mods are freeing up air flow by reducing back pressure in your exhaust system and maybe reducing any "bottlenecks" in the intake but even that doesn't mean much.

The most air that you can suck into the engine N/A is just what the engine is willing to take in the amount of time it can when the valves are open. Mathematically the theoretical amount of efficiency you can get is 100% which could theoretically be obtained by a stroker kit and free flowing intake/exhaust tuned to a desired RPM.

Realistically without F/I you will never break the 100% volumetric efficiency or even come close.

Update: took it off and put it on sale board...back to K&N...just oiled them and wait for to dry....lol 😂😂😂😂http://uploads.tapatalk-cdn.com/20160916/91d60873292b9afa780dc656bb0b0cf5.jpg

I respectfully disagree on that.

You are correct in saying that the theoretical amount of air that can be drawn in the engine is 100%. But, that's only THEORETICAL! In reality it's probably more along the lines of 80%-85%, but that's besides the point.

On a naturally aspirated engine, with a well designed induction system, you can definitly break that 100% mark without forced induction, using a process called pressure wave tuning. Definitly look it up if you don't believe me. I'm not making this up.

[ern-diz]

Given that one of the first things people do to improve performance on just about any car is intake/exhaust system to let the car "breathe", gaining power from it makes sense to me.

A lot of people have seen the F&F movie series and believe everything that see, stickers don't add HP

Don't get me wrong, a well designed intake/exhaust setup will increase power. But blindly adding parts because everyone else does is stupid.

I am not sure what you are trying to disagree with here. I said theoretical, not practical. Yes in reality your engine is only 80-85% as effective sucking in air without any other factors.

You must also skipped over the part where I said "tuning for a certain RPM" even with pressure wave tuning it is only tuned for a specific RPM that is why there are different length headers which move the powerband up or down depending on the design. The engine itself can't achieve 100% VE at all RPMs, it can be considered a narrow powerband when compared to a FI engine where a compressor is used to force air in and increase VE of the cylinders.

How's the power gain vs gas efficiency ?

you will gain some hp and some sucking sound...i already put it on sale for $60..+$20 shipping..lol 😅😅😅
if you live in a hot ass country like me(40c with 100% humidity)..sri or cai will be same as drop in with slight gain...i really recommand sri or cai in cool country...
