Is a skunk inlet and throttle body a good upgrade for a b18c-r engine

I dont mean any dissrespect but you clearly dont understand engine tuning or air flow characteristics at all.

Absolutely none taken, never claimed to kno, I'm reading as many posts and threads on here as I can trying to get my head around it all! Sorry for the spasticated questions lads
 
I disagree I've defently noticed a huge difference when I put it on my b16b
 
Lo

Don't worry about it mate. There is only a few ways to get answers, experience, lots of research or just ask.

There is a big difference between throttle response and actual power/ torque gains.

I wasn't going to be the one to say it. Lol

Just to add more food for thought, the NSX is fitted with a TB of only 64mm butterfly.

Yeah I suppose its properly in my head, that's crazy a 64mm tb in a nsx, does anyone know the reason behind this, pushing out all that bhp with that sized tb crazy lol
 
It's all down to the physics of air flow, velocity and efficiency.
 
I got a skunk 2 intake and skunk 2 throttle body for my k20 and it made a big different . I think any way .
 
k20 different engine than any b series tuning is different, has some basics but is different car to car engine to engine..
 
The 'Honda fitted it, so it must be the best one to use' dosent make sense to me...

For a start they are building engines with lots of restictions, noise, emmisions etc

Secondly, most people have other mods that may benefit from a bigger TB or diffrent intake.

The engines that come stock in our Type R's are great, but are still comprimised in terms of all out performance and can definatly be made better.
 
thing is though why would skunk2 go through spending thousands and thousands on developin and resaurch if it made no dirrerance thats how i look at it well maybe not on a stock engine but when your modding i.e. exhaust mani cat-back and ecu and others more air and fuel in more out does make a differance maybe not alot but they all add up to a big differance
 
Why cant people research actual engine tuning, part designs, differences and their influences on the characteristics of an engine's performance.

Not just will "X" manifold give me "X" hp ??!?!
Everything in the engine is relevant to everything else.

An engine in its basics an air displacer or pump to be even simpler. Puting a big pipe going into a pump will not make it flow any more air!! As the internal valve size, open durations and lift have not changed!!

Little test. Anybody can do.
Start with a Pint of water in a glass.
1. Get a normal straw from say Mcdonalds 6mm ish and suck up the water.
Results will show: Quite small effort is needed to suck the water through the tube Correct??

2. Now go find a piece of pipe like 25mm or 30mm (basicaly bigger).
Results will show: It would take more effort to suck the water up through the larger pipe Correct??

Everything has its optimal flow rate for given forces, efforts and volumes.

Also size isn't the only factor you have to concider length , i.e length of runners, distance from the throttle butterfly to the valve opening, plenum chamber volumes. ect.

Something does not need to be made bigger untill it is found to be resricting the setup you have. As for intake manifold design, that mainly only infuences engine characteristics and shifts the peak hp around. As the std unit actualy flows as well as is needed for the given std power band.

What makes you think they spent thousands on research???

There first Gen1 manifold was a copy of the Type R one.

Then they just changed it a bit to work better higher in the rev range with bigger cams.

From what I have seen about their products Its not exactly top shelf stuff more of a cheap altenative that branched into tuning.

its true:nice:
 
I pretty much agree with everything Kieran has said here. I highly recommend a book called X-treme Honda B-Series Engines by Richard Holdener who owns the worlds fastest Civic (in a straight line). It basically goes through what works and what doesn't depending on what you've done to your engine and has loads of dyno comparison graphs.

Just turning to a page I'm reading right now shows a dyno comparison with different intake manifolds on a stock B18A. I can see that a Type R intake makes +1 peak hp but actually loses 10hp at around 7000rpm. Pretty much the same story when comparing the stock B16A intake to an Edelbrock Victor X (also losing a huge amount of torque up until 8krpm). In fact on a turbo B18C making 494hp made exactly the same power and torque as when fitted with a bigger 68mm throttle body.

You really need to at the very least upgrade to some pretty aggresive cams to make proper use of aftermarket intake parts

Yeah, so it'd make more sense getting an integra type r intake and tb and getting it remapped properly by hondata or someone, right?

Don't do it! Save your money for something that will actually make a difference, read my prev post :nice:

Turbo up in other words?? :)

Is there anything for like 4/500 quid that will give my car that extra bit of umph? Or is the turbo the only thing worth thinking about?
