Intake manifold

[CAUSHN]

Hi guys wanted to get some opinions on best intake manifold for a h22 engine??

they make adapter plates to mount k series manifolds onto a h. the plate will make the runners longer and thus lower the power but its only half an inch or so. is the engine stock? boltons and tuned, cams ect ? ? whats the best for one engine is rubbish for another....

longer runners move the powerband lower, shorter - higher. heres a quick idea.... http://i680.photobucket.com/albums/vv170/ParleyBaer/WavePulseRPMChart.jpg now runner diamiter and plennum volume a dictated by engine size and rpm. (the length also plays a role) you might want better low end, go for a longer runner, or you might be building a drag motor that only sees 3k rpm once a race. go for a shorter one. do research into what k manifolds make good power on h22's. try and look for dyno comparisons and not just peak hp numbers, then you can see where the gains really are in the midrange.

the k series manifolds seem to be quite well designed. if you port it or get it done, the runner length can be changed at the bellmouth to accommodate the additional length gained with the plate.

Dont waste your time with a K series manifold on a H series. They flow too much air for the engine to handle.

Best OEM manifold as said is the CL1 Euro R manifold

What do you mean by flowing too much air?

[stndrd]

The flow rate of the the RBC manifold VS the flow rate of a H22A

The RBC flows more air than the H22A which means the intake manifold is over powering the engine.

Each component of an engine is designed to work in conjunction with every other part. Get one part wrong and you won't make proper power

What if the OEM h22 intake is actually the wrong part?

At the end of the day it all comes down to how you build the motor but for a bit of OEM upgrade on a stock H22A, the Euro R manifold is the way to go

currently the engine is standard but plan to do more work to it but keeping it n/a

But here you are saying that the k series are not good enough?

So which one is it? Is it based on how you build your motor or the particular manifold?

Should i ask cbauto?

The k series manifolds are not worth it on a H series.

If you cannot understand that, why waste peoples valuable time asking questions you do not understand

Im trying to understand YOUR point that you are trying to put across, I understand what manifolds are worth on H series.

I personally dont see any reason why K series manifolds shouldnt be used on a H series motor.

Firstly, if the engine has aftermarket camshafts, you need to look at where the camshaft centre line is, the profile of the lobe & where you have dialed the cam in at. This dictates the runner diameter & length of the manifold, along with plenum volume. If the plenum & runner size's are too big (in which case the RBC is) there will be no air speed to force the air into the engine
