Induction k&n typhoon installed

big-kim · 11th September 2007, 16:37

last week i installed the typhoon kit on my civic
and yes it doenst fit perfect en the europe version (see pic)
the sound is nice, i dont know about the performance the car should go 205km/h top speed but i get only 199km/h out of it
anybody good advice for a good exhaust?

I don't think you're likely to get any huge performance gains from fitting this (personally)

especially as it remmoves the top of the airbox, allowing whatever air is being forced into the box to simply escape out of the top.

But there again, my experiance versus K&N is rather small, so what do I know!

what was the top speed before you fitted it, and is that real speed, or speedo speed?

I agree with TT, you were never going to get massive gain from it. Fitting a turbo (pretty much impossible due to the cramped engine bay) would give much better performance.

Guys, you can't tell if it's any gains in power until you have a dyno graphic .
In theory, short induction kit, should provide more power.
If you could isolate (for heat) that filter will be great .

How does it feel the car now, driving with this ?
Maybe you can post a sound clip ?
The only exhaust I know, made specially for out civics are those from REMUS Racing

ttdegs what doe you mean by speedo speed
my top speed before was 195km/h
it feels like its going faster maybe its only in my head

Mmm I think the idea of fitting an induction kit on its own is really for the sound rather than the power. Usually if gains are made this way, they are gained at the detriment of power elsewhere.

The theory of a shorter induction does run true but depends on many other factors i.e valve timing/lift, exhaust design and length etc. The CTR engine would need great modification to run a turbo properly. The compression ratio is so high as standard that this would need to be reduced somewhat. You can only squeeze so much air/fuel into a combustion area without something giving.

I guess the moral is its horses for courses! If fitting one make you feel better and don't mind the car running rough at certain revs - go ahead

If you do - leave it alone

dinoc, yes, you are absolutely correct - short of a dyno run before and after, there is no way to tell.
However...
My gut feel is that it is not the air filter which is the bottle neck in the limit to the performance of the engine.
If it were, then, especially when dirty, the engine would not be getting enough air in, and would try to run rich (too much fuel, not enough air).
Though clever ECUs and sensors would prevent that these days I guess.

Therefore, in the abscence of any other tuning work, allowing the engine to pull in more air (when it had enough already) is, (again in my understanding), not going to generate much, if anything, in the way of extra power.

But like I say, I could well be wrong!

Certainly, if you were to do some other performance mods (be that whatever they could be), then at some point the standard air intake system will become the bottleneck, and fitting a K&N (or whatever) at that stage could well release some extra poke.

In the mean time though, it will sound good

The speedo is far from accurate - reading by as much as 10% high

However - if it feels faster (and it certainly should sound faster

), then it's money well spent

I also feel that there isn't improvement in preformance, but should make the car sound better...Do you have a video clip of how the car sounds with this induction?

nortones2 · 12th September 2007, 10:49

If the intake gets warm air from the engine compartment, it will likely achieve a power LOSS due to lower density of the intake air.... I remember asking K&N for performance data when I was thinking about changing an air filter. They were't forthcoming, so I gave up the idea, and kept to OEM paper filter, which at least filters properly, which is its prime purpose.

Nick7 · 12th September 2007, 13:38

Well, all you got now is better sound (if you were looking for that

).
But as performance goes - you could notice power loss, as engine is now sucking in warm air from engine compartment.
Warmer air = less density = less mass per same volume = less power.

civicg · 21st September 2007, 21:49

At best you will see gains top end and perhaps a bit of lag when setting off.

I had tried 2 different induction kits and a K&N Panel filter in the previous car and I can honestly say TT and Mark have it spot on, its more for the sound, the rest is horses for courses.

A induction on its own will not give you noticable gains. Looking at the typhoon the heatsheild will help with heatsoaking however the filter is still exposed. It doesnt help that its located at the back.

The best mod would be to fit a scoop on the bonnet (Extreme I know) so cold air is fed straight into the filter. OTherwise try to get a direct air feed from the front to the induction kit.
