best induction kit please for a jdm sti 03 wit twin scroll and equal lenghth headers, im running around 335bhp and want more!!! (have panel filter at the mo)

 

They are all WORTHLESS and give you heat soak problems, use a standard airbox with a high flow pannel filter..

Unless you can locate the filter outside of the engine bay or completely and I mean completely seal it off from the rest of the bay.

 

I think you are being a bit extreme there Davey... yes heat soak is a problem and needs to be considered but they breath so much more freely than a panel filter.

 

But what good is it "breathing better" if the air is 20 degrees higher in temperature and thus MUCH less dense..

 

so you think it is good to be struggling to suck enough air in?

 

If you've reached the flow limit of the air box then you have reached the limit of the MAF and pipe to the turbo so the induction kit wont make **** all of a difference.

 

I am sorry but you are just showing how little you know..

the maf on his car is capable of running 500bhp+

 

Where did I say it couldnt???

If thats the case then the airbox should be able to flow just as much air, just fit a decent filter plus the added benefit of the air actually being cold..

Unless you just want to impress the girls outside tescos with your "induction roar" ??

 

Its always quite handy when someone with incorrect views on the subjects posted in technical forums decides to post and sound like a font of all knowledge!

[Davey], there are others on here inifinitely more respected for there techy knowledge than you (JGM is one of them), please stop posting your (incorrect) views, and then arguing with some of the more respected Technical authorities on here, it really doesnt look good

 

Tony, what do you expect, look at his location; Berkshire, says it all really

Next thing you know he'll be telling Pat and Andy how to map cars

 

Hi Mate
Back to your original question
I have a 400BHP sti 7 , and have a K&N mounted in the wing where the resonator normally sits, connected to a cast APS intake pipe which houses the MAF, elbow than into perrin through to intake manifold.
Much less restrictive than OEM airbox and pipework, and filter is isolated from engine bay heat
Can send you pics if you want
All the best

Roger Clark's do and excellent induction kit that uses a K&N filter.

This can easily be shielded from the rest of the engine bay and fed cold air from the inner wing.

I run at a maximum of +2 degrees above ambient during normal driving conditions.

^^^Now that is the correct solution

I say Listen to this guy instead of these "respected tuners" I have argued with?

 

Sorry, but how does feeding in cold air from the inner wing shield it??? The air filter draws in 1000+ gallons of air a minute do you really think it will some how by magic suck it all in through this special pipe when its surrounded by hot air in the bay?

 

To be fair, It doesnt look as if it has slowed Andy F's car by having the induction kit in the engine bay (but then again, I guess you will tell him he can expect another couple of tenths if he put it in the wing?)

Someone has already stated that intake temps were only +2 above ambient, why do you disbelieve him? FWIW, my car runs +3-+4 above ambient (unles sitting in traffic where there is no air flow through the engine bay (but being as the engine isnt under load, I do not worry so much )

 

But the problem is the Majority of us have daily drivers that arent soley for use on the track, therfore they spend time stuck in traffic and pootling around town.

 

My daily driver runs an induction kit. Yes cold air to it is important but there comes a point when you need more air than you can get quick enough through the air box and your initial statement that
I am sorry but it is bollox..

Ambient of 20, air filter temp at 36, throttle body temp of 25degrees.. and that is after going through a GT30R.. estimate 420bhp at the current time.
I have no shield on the induction kit..

Just think with proper cold air induction you might get a few more horses

 

so you mean your first post meant to say

Make sure you have a good cold air feed to it, or in a cold air box or outside the engine bay even better?



Simon

 

Of course I'm not saying induction kits are uselss 'end of', but when whacked into a hot bay they are more likely to cause a power loss than gain.. In 99.9% of cases the standard air box will flow enough air for the engine as most are using the standard MAF and inlet pipes...

If you have mounted the filter outside of the bay (as a user above has mentioned) and gone down the route of removing the restirction further up the line then ofcourse you will get massive benefits!
