"When people start modifying their cars, one of the hardest things to convince them of is that the manufacturer isn't stupid. Everything in your car is there for a reason and not there just to reduce noise and rob you of power. The most often removed and least understood "mystery piece" found on a motor would have to be the humble inlet resonator. Normally formed from unattractive black plastic and bulbous in design, the inlet offends the ignorant for a couple of reasons. firstly the shape and size of the resonator makes people believe that its just a tacked on afterthought to make your engine bay look fuller than it really is. The second myth is that the inlet resonator is there to quite your engine by reducing induction roar. In fact, the inlet resonator is a carefully designed pert of the induction system, match to the particular characteristics of the engine it is mated to.

They come is several different designs, such as side branched, inline (inside the induction tubing) and mounted top and bottom. Rather than affecting the peak power output, they can have a dramatic effect on the smoothness of power delivery and bottom end torque of the engine. This is why fitting an aftermarket inlet system can often make your car perform worse than it did originally.

Those beautiful looking stainless induction hoses with a pod filter at one end invariably replace the engines inlet resonators, which may offset the power gain the pod filter offers. It doesn't have to be this way. The really switched on aftermarket players like ARC in Japan now offer inlet systems that feature their own side branch resonators to optimize inlet tuning and not waste any free power...I mean for ****s sake, isn't it worth keeping an un attractive piece of plastic for those hand full of free kilowatts? By all means go for a pod filter, just make sure its suited for your air flow sensor (Mitsubishi vehicles MUST use a K&N oval/round 360 degree filter, for details click [HERE] for details.)"

Thanks for the info!resenator1.jpg

PVA-Glue,

Its true these things affect power on N/A engines! The resonators allow the flow of air to be increased. They do this by literaly creating a mini atmosphere where a reserve of air can be stored for the engine to use!(virtually making the inlet pipe shorter) But because these resonators work on acoustics it needs to be tuned to the engine!(only works on N/A engines because these engines need to suck the air that they need.)

This link might better explain it.

Its a Soarer site, but they use a flow chart to explain the principle of these resonators. (very interesting for N/A owners that want to remove that ugly piece of plastic that actually helps it run better!)

    • Once you go non OEM DBW e-throttle, you'll never go back to a cable throttle. Just so good in every single way.
    • Feels like most tend to keep it under 8000rpm for hydraulic lifters. Quick search on the net and those on Rennlist like to keep theirs under 7500rpm, Speed Talk under 8000rpm. Perhaps start to take timing out for 7250rpm and soft cut it by 8000rpm.
    • Ok, so I just had a chat with my mechanic. He said there is no real source of lead in the engine, the bearings and pistons are aluminium and the rings I think he said are steel. He doesn't recall what additive he used but that along with the thicker 20w50 he used could be a source of lead. It's put me at ease a little bit and I guess I'll just have to wait 5000 k's to do another change and see if anything is different.  I appreciate you guys chiming in. I have a habit of immediately thinking worst case with things like this.
    • Finished street tuning it to 20psi with WMI. Haltech really makes it easy for you with those 4D maps. I have 17psi springs in my gates but they seem to only start cracking around 17 and taper off around 19/20psi. I was originally on 14psi springs but I'm expecting to need ~35-38psi to hit my goal and I was worried It wouldn't make it. Dyno's booked for next Friday. All I have left is to replace my el cheapo amazon special type k connectors on my EGT's. They have no strain relief and well are just all around cheap compared to what I use at work. I had the wires in one get lose and I don't want a repeat of that on the Dyno. I also want to figure out why I have 4 cylinders that are perfectly identical, one that's 30C over and another that's 30C under. I'm chocking this up to EGT position in the runners not being identical and will verify that as well. Wish me luck! Hopefully I make all the power with no bang. Question for the group, I have my rev limiter set to 8000rpm. I have a fully built head and new lifters but I stuck with hydro's. Is 8000 fair or am I being to cautious? 
    • Anyone used A to Z Imports in Goldcoast?  I was referred to them for engineering and RWC? However besides a few one off bad google reviews it all seems pretty legit?   https://www.atozimports.com.au/
