Effective NA Power Mods

Thank you!

Well its a 2.3 liter stroker engine 13:1 compression and race cams

I believe the power band down low will be fine with the compression and larger stroke. I need it to breath up top

Anaconda 48mm is based on fairly specific parameters. If you are interested in that realm, we can have you fill out a form to identify whether or not the 48mm is good for you.

Shifts the powerband north the 250. The collector design shortens the "2" section and lengthens the "1" section in the 4-2-1 header. For reference, we have posted up a video of an owner in Korea running an A-150 doing 8k pulls on track.

All based on the type of scavenging characteristics and needs. While it can breathe to 9500RPM, what about usability and application? The Synergy V8 runs to 11000RPM, but it looks like a slug coming out of corners due to lack of torque. We'll discuss when you're ready to order. Thank you!

So I've read a few things on here in regards to drop-in K&N ( bolt on upgrades sticky thread) or TRD , vs going with a full out ($350+) CAI system.

So what is the consensus ? Is it possible to go K&N drop in, and rig up the snorkel air inlet system so it's sucking in colder air from outside the car ?

Thanks in advance

Most NA mods won't provide significant gains without a custom tune.

A drop-in filter is all you really need. It's already pulling air from the mouth of the bumper. The OEM intake is very very well optimized. Most of the CAIs "make" power by leaning out the AFR, which is bad. The one that doesn't is GrimmSpeed. They have a thread covering the development and testing of their intake, and they did a great job with it. If you really want an intake and you're not going to get a tune to address the AFR issue, get a GrimmSpeed intake. Otherwise, get a drop-in filter and call it a day.

Anyone know a drop in that fits the 2017 /w manual trans yet?

@Somerandom18 : it should be the same as '13-16 model years.

Thanks for the input you guys. I've done some research into this, but yeah sounds like a drop in is best overall cost/benefit ... ROI . Thanks again for cutting the crap out (filler) , and getting to the heart of the matter.

Here's some reading material for you, detailing testing of the OEM intake with factory and modified snorkels, aftermarket filters, and design of the GrimmSpeed intake.

Same drop in that fits the 2013-2016! Nothing special really

[Adam_L]

Next quick question, Intake related . On the new '17 red intake manifold (trying to find the thread on here that outlines the '17 changes) , has anyone done any tests to see what kind of (real world) bump in hp/torque changes there are by adding this to your FR-s /BRZ ?

It's not. The filter design was changed for 2017 manuals along with various other parts of the intake.

Same filter size though! So replacing it with the same aftermarket filter used for 2013-2016 should not be a problem.

Does the drop-in-filter filter as well as oem? Best of luck finding information on this. It may be the drop-in-filter is high tech and removes as much particles as oem but who knows? It is also possible that less filtration only makes itself known after 200,000 kilometers. I am suggesting filtration is inversely proportional to air flow. I am not saying you don't get a drop-in but you know, compromise.

You might like to get an used oil analysis done to see how the drop-in is working.

My car has only has 46,000 kms on the clock but has had 4 oem filter changes just because.

One can get more air flow even with same filtration, if eg. filter's filtering area is larger then that of stock (by eg. more and higher folds or bigger box/filter itself like in TRD intake). I've also heard that oiled filters can filter better if of same resistance then dry ones.
Of course it's also possible for some aftermarket filters to decide on different filtering/flow compromise sacrificing former for later.
