which one is better ??????

[jim_bling]

hey peeps sorry if this has been asked but which one would be better ??

or would a pannel filter with better cold air feed be better ??

thanx for any replys peeps

ken

 

[Retepetsir]

Are they oem kits or branded ones? The top one should see some improvement in low down torque. Not sure about the bottom.

 

[joesouthgate]

a panel filter will normally give better gains but u dont get a sexy noise

 

[TredderK11]

Don't get the top one there not actually for the K11 I got caught out by it had to mess about for ages getting it to sit properly and as soon as i got my new micra it wouldn't fit at all not enough room for it.

 

[pixieness]

Oooh. Tubes. What are they and what to they do? (Give me information! :grinning

 

[ollyc98]

The second appears to be a cold air feed/ ram pipe type of setup. Will make your engine bay sparkly if your into your blingbling lols.

TBH anything is an improvement over standard.

 

[pixieness]

I see I see! Merci beaucoup.

 

[Craig]

TBH anything is an improvement over standard.

Is that actually a proven fact?

 

[Retepetsir]

Nope. However the induction setup on mine gave an improvement over standard, proven and tested on the dyno with different pipe lengths to boost torque between 1.5k and 3k rpm

 

[Craig]

no complaints there then...

 

[Retepetsir]

Nope! Glad I wasn't the one doing it, Dan did it all for me

 

[Robert]

Care to share how big your piping is?
I think i read somewhere that the volume between the TB and filter should be the same as the engine size, so 1.3l? Or was that not true?

 

[Retepetsir]

Something along the lines of that. I know that it uses the second and fifth harmonics of the pipe in order the increase to torque. Ram air theory...

so if i get a K&N panel filter with that second one aranged towards the front of my car that would give the better gains

Cool cheers

Second and fifth??

The best gains will (I reckon) be had by ducting some air to an enlarged airbox opening, would be nice to do some testing on it, but that is amaybe a job for the summer...

the second one is better. you don't want to have an open filter in the engine bay because you will suck in hot air from the engine bay.

the best option would be to have a filter right on the top of the TB that sticks out of the bonnet, because you get a nice cold air feed that is isolated from the engine by the bonnet, but it is still the shortest distance to the TB

 

[Alienfish360]

there should be 130% of your engines capacity of filtered air, between the throttle body and filter for optimum throttle response.

 

[Robert]

So about 1.6l?

 

[Alienfish360]

1.69

 

[Robert]

I got 1.657 or something
I did it from 1275 rather than 1300 though

I need to move some bits around my bay though, damn it!

Yep. Do some reading on ram air theory

 

[Craig]

I basically wrote the book on ram air theroy, just wondering how you can have an even and odd harmonic?

:laugh:

I'll try and find out some more details about it. I was talking out of my arse and it was late, I meant 2nd and 4th . The intake length was calculated to boost low end performance.
