I got a little bang out of a K&N drop in filter
el butt dyno isn't very accurate. although a K&N cone filter will help, a OEM replacement won't do anything. air restriction difference is virtually nothing and offers no added surface area for air intake. cone filter and proper cold air intake will help however.
I am told that removing the intake resonators opens it up a little more, will try tomorrow.
those resonators are designed not to impact air flow and do that rather well.
Also plan to try a free-flow cat and muffler. No one makes a chip. Not much else you can do.
free flow cat and muffler will help, but gains will be much better getting a full cat back system installed. many of the restrictions are the bends in the pipe. as for the cat, gains there are small since modern cats aren't too bad for backpressure. also, emissions can sometimes be a concern if you have to get your car tested every now and then.
gains from chips are pretty small without doing other mods first. the chip should be to support mods and tune the engine to better use them - changing the ECU to provide better power usually yields minimal results. rationale: if there were major gains, why wouldn't hyundai do that from factory? doesn't make sense.
Synthetic oil might add a trifle.
wish it did. in the crankcase there are no noticeable gains, but it IS better for the engine. noticeable gains can be had from using synthetic in a manual gearbox however.
Weight removal also helps - leave the spare and tools at home and don't haul a lot of stuff in the back
yes weight reduction is always a help, just not much. it already has a hefty weight so removing items is a drop in the bucket.
Any other ideas, please LMK
- cold air intake, replace the entire intake up to the TB. if you want to go cheap, you can always use ABS drain pipe. PVC is a no go, the chlorine can cause engine damage over time.
- exhaust. best bang for the buck is a proper cat back with mandrel bends.
- a header would help if you can find one, but beware of the emissions thing again. some headers require removal of the o2 sensor. not too familiar with under the hood of a santa claus though. toss removal of sensor in the maybe pile.
- if you have steel wheels, lighter alloy wheels are an expensive but nice little upgrade. weight reduction on rotating mass does far more than stationary mass.
- how handy are you with making things? look up individual throttle bodies. fun stuff.
- head porting for the more adventurous.
- upgraded cams if you can find them.
- for the best gains, turbo or supercharger all the way. it'll cost you but will yield best results.
