No offence man, but honestly - don't open it. Send it back for a refund and if you must spend that $180 USD, try and get a lambda sensor for one side and then down the line buy another and install them together. There is zero chance of any gain whatsoever with these spacers. By all means, do the charcoal delete though. If you do the charcoal delete and spacers together, you'll think the spacers aided a little with the slight power gains, but I'm telling you - they won't contribute to anything positive. You'll benefit from more response and power down the line with brand new Bosch lambda sensors, than these spacers.

We miss you Celica

Dont listen to this guy, take another 180 and buy another set and double stack them. I'm telling you the added volume will free up about 13whp.

and send my that o2 sensor.

Seriously though whomever is trolling as Dustin Thomas - good work bringing back this thread, I have missed it for a while!

Me too man. The cars that I have are all 20-27 years old now....there's no fun forum community for them. Nobody innovates anymore and I can't possibly achieve anything new or exciting, because it's already all been done. It was fun chasing that 600hp M156 over here....but gosh, what a waste of effort doing it on a heavy W212

Funnily enough, I saw my old car on eBay recently and it sold for way more than I'd sold it for. No mention of the Kleemann cams or the custom tune that I had put in. I'll bet he has no idea of the tribulations that the car achieved in a previous life...hehe.

I heard you also lighten up the car by draining all the oil as well. Throttle response really improves but the engine is a little more noisy...

Well look at it this way weed is legal. Maybe you shouldn’t drive while your high or post things
While high either. I have a thought maybe grab some jack and the box and think about the S
Your posting.

This is the funniest threaf ive read in awhile...

still....was hoping for some ryno results. I was kinda rooting for the Moron to have some mild gains.

Logically though intake spacers in that car is a joke of a purchase. 20 hp is a joke. Maybe 1-3 with 5 peak at most

Old thread!
Just read it for my own amusement, forumheroes with a lot of posts can post whatever they want and be trusted as the bible.
Won´t mention any names but the guys i´m talking about is often seen in performance upgrade threads talking down newcomers.

However!
Three basic rules to allow more power beeing produced:

First rule of engine breething, get rid of restrictions!
Second rule: Raise air density into cylinders!
Third rule: Engine doesn't suck air in, it creates lowpressure that atmospherepressure is equalizing.

Get rid of restrictions?
Yes anywhere in inductionsystem there might be restrictions, there is always gains from either removing the restrictions or optimizing to get lower restrictions.

Raise Air Density?
This goes hand in hand with removing restrictions but has the other hand grabbed to temperature,moisture,pressure.
Make sure your engine grabs as cold dense air as possible, and try not to heat it up when going into engine.
As engine always pumps it´s volume no matter what angle the throttles are in, the throttles only restricts the air and gives less density to fill the cylinder with.
We need to make sure we fill the plenum with as dense air we can when on full throttle, this by larger throttlebodies, optimize air passages going into the throttlebodies.

Air sucked in?
No! or yes the guy that are unaware of physics is getting away with that statement, but in a group of more well educated people they´re just a fool.
Engine uses it´s power to draw lowpressure through the intakesystem that the atmosphere pressure tries to equalize, thereby air is pushed into the engine.
Can we lower the losses for both (power consumption and less restictive system for mother nature) there is always a gain.

The spacers won´t give you 20whp, but for the price and possible gains(say 2-5whp) they are worth having a go.

And the guys reading air grams going through the air mass meters, you should not trust this 100%
To get correct reading of airdensity one need a far more advanced metering system, the airmeters are 'good enough' to get almost correct mixture(oxygensensor does the final touch).
Why you might think?
It is because the airmeters actually reads a little bit wrong with moisture in air, more moisture = less oxygen, but more moisture cools the tempsensor in airmeters and airmeter is reporting more dense air going into engine.
But no harm done, as the oxygensensors will pick this up and send info to ecu so the ecu can correct it.
So an engines 'airdemand' if reading the air grams will alter from day to day, and where you are located.
I would actually give LTFT(long term fueltrim) more focus, as this is the result of what has been going into the engine and how much fuel needed to burn it correct.

Lastly, air filters are NOT the restriction if having a good proven filter like K&N among a few others i can´t remember the name of when typing this.

And bonusquestion, where does the engine consume most air per cycle?
Bahhh i´ll answer it as i figure there are actually really few that will get this correct.:
The most air consumption per enginecycle is at peak torque(actually sliiiiighly above, say 50-100rpms, this due to frictionlosses)
But in the region of where torque peak is, there where it´s at.
This is interesting as due to effiency of intake system you can get lower air grams running into engine at 7000rpm than at peak torque rpm, say 4500rpm.
And if having this phenomena there is always gains from optimizing intake system.

Thank you!

I agree with most of that.....but you say that the engine does not suck in ... then describe how air is pushed into the engine by atmospheric pressure trying to equalise the pressures....which is the very definition of suction.....!

I just bought the lower airbox housing for the hammer supercharger kit(larger than stock). Hopefully the larger boxes do something other than take up more space in my engine. But, for the price(less than the spacers) It doesn't really worry me if they don't do anything.

swedepat

Every project i´ve been involved with has always made some gain when opening up the restrictions

swedepat

It alters the way of thinking when you are trying to undertand movement of air.
This and eddies, bernoullis, and coanda are important things to have back in the head trying to understand.
And it also becomes more visible how and engine breathes and how efficient the world can fill the cylinders(atmospheric pressure, 1bar absolute at sealevel)

BLKROKT

How does a gallon of gas in your cylinders, because you didn’t keep up with basic maintenance, affect the eddies, bernoullis, and coanda genius.

LOL

swedepat

You are one of the people i´m aiming at with my posts in this thread.
Feel threatened that your high horses are just some shetlandponnys?
So porting and airflow theories are totally wrong as i had the bad luck of having an injector got stuck?
And please tell me how to tell if injectors are going bad in advance, so i can dodge the bullet next time =)

Worst of luck getting your shïtty car running again. And yeah, injectors are a standard maintenance item.

LOL this thread literally saved me $200. I was on the fence.
