Paul Laing Posted October 16, 2003 Share Posted October 16, 2003 What about a induction kit in a custom cold air box, something like Envy do? Thats gotta be better than a paper restrictive air box hasn't it??? Link to comment Share on other sites More sharing options...

Thats gotta be better than a paper restrictive air box hasn't it??? The stock system is not restrictive, it has a paper element filter, which is the best filtering medium currently available for dry filtration, of massive area, to allow long service intervals in dusty climates without getting too clogged. Why reinvent the wheel? I could sell dozens of "induction kits" fit them without hassle and take a good margin. I don't as I have proved to myself they give no more power, and often sap power. Jeez, I have spent some serious time and money on some of my own cars, and I have never had an induction kit on them unless they were so hacked about the stock air box had to go for clearance or radical none standard swapping of bits reasons. I don't have a problem with people fitting them (no, really I don't..... ), but I hate to think people really expect them to do anything much!

Why reinvent the wheel? Exactly. I'd think that Toyota spend more than a few bob on getting the design of the airbox exactly right, more than any aftermarket company could dream of. How many aftermarket kits retain things like a cold start mechanisom from the exhaust? Or crank case ventilation? At the end of the day, its all down to the noise it makes really, come on, own up ;-) PS. I've got a cone type filter on the Rover... but hell, it came rolling around in the boot and I'm under no illusions that it boosts power by Nova SR proportions! It just sounds good Link to comment Share on other sites More sharing options...
Paul Laing Posted October 16, 2003 Share Posted October 16, 2003 ok ok, who wants to write to Blitz, Apexi, HKS etc and tell them this??? What about a cold air box for the induction kit? Would this work better, as the filters give 15bhp etc which has been proven.... Paul Link to comment Share on other sites More sharing options...
Guest Terry S Posted October 16, 2003 Share Posted October 16, 2003 Chris has said on more than one occassion that the stock air box is sufficient for most of you. You could be losing power with the others due to it picking heat up from the engine bay. If you were running wild hybrids and it was a restriction then fine, but at moderate power levels why bother. I think Envy sell a trd replacement element? Why not try that. If you just want it for noise,some guy on E bay is selling a CD with wastegate noises on it:innocent: Link to comment Share on other sites More sharing options...
Steve W2 Posted October 16, 2003 Share Posted October 16, 2003 I think the issue of after market filters giving extra BHP gains is down to the fact they let more air through the filter. Great if you want a few extra ponies but it must cdome at the expense of filtration. Cold air or not if the filter is not as efficient as the standard one then it's not worth the hassle it could cause. I'll be sticking with the standard box myself:) You may well have no problems as a reult of using an aftermarket filter but you should be aware that the life of some of the components (major ones as CW points out) may be significantly reduced.

Paul Laing Posted October 16, 2003 Share Posted October 16, 2003 come on, wheres all the people with induction kits to back me up???? lol nobody has said whether a sealed cold air box with induction kit inside would be better than stock. But it has to be!!! Paul Link to comment Share on other sites More sharing options...
Willson Posted October 16, 2003 Share Posted October 16, 2003 I have the HKS and I only have it for the noise. I personally didn't notice any improvement when I tried a stock air box, but I am sure they are 'better' in every way for a basically stock supra. I do not believe the 15bhp gains for an intake at bpu at all. Link to comment Share on other sites More sharing options...

Chris Wilson Posted October 16, 2003 Share Posted October 16, 2003 Originally posted by GavinL Where has this been proved on a MKIV? I have never seen any wholely independent tests by an accreditted authority showing any gains at all. Most mags never test them, or utter a whole load of waffle to explain why no gains are shown, they are too dependent on the sellers of these things filling the advertising departments coffers to speak the truth, IMO. Paul: I can't see why you should be so adamant that a different filter SHOULD give more power? The makers want the most efficient engine they can offer, and fitting a restrictive air box or filter is the easiest way to kill economy and efficiency I can think of.

Paul Laing Posted October 16, 2003 Share Posted October 16, 2003 I can see where your coming from Chris, and oviously you have loads more experience than me with cars!!!! It's just for about 4-5 years iv'e allways been told induction kits are the way to go as they let loads more air through, the more air let in, the more air out, and thats where you get your extra power. Plus all the japs use filters, is this because they run over 500bhp and to run that you'd need a induction kit? Or maybe like you said, they have went single turbo and they have to get rid of the standard box. Paul Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 16, 2003 Share Posted October 16, 2003 They use them because the advertising execs do a good job. Marketing and fashion people are responsible for a lot, platform shoes, body piercing, raw fish restaurants, over tyred cars, induction kits...

Marketing and fashion people are responsible for a lot, platform shoes, body piercing, raw fish restaurants, over tyred cars, induction kits... Polyphonic ring tones... I have an Apexi induction thingy that came with the car and I like the induction noise lots. I've got a shield that stops the engine fan from blowing hot air straight into it, which helps a bit I'm sure. Building a cold air box around an aftermarket filter smacks to me of junking the stock airbox and filter then... spending nearly a grand reproducing it I admit these pod filters probably don't add anything and more than likely lose some power in some conditions. But that noise is great I wouldn't touch the HKS mushroom filters after what Chris experienced though. -Ian Link to comment Share on other sites More sharing options...
Terminator Posted October 16, 2003 Share Posted October 16, 2003 Originally posted by Paul Laing come on, wheres all the people with induction kits to back me up???? lol Paul Sorry can’t back you up. I made the mistake of buying and fitting an induction kit. After one track day I was convinced that it slowed the car down coming out of slow corners. Cured the problem buy taking the head lamp out to feed it cold air. Back home I did some road tests swapping between stock box and AM filter kit. In warm weather and at slow speeds the difference in throttle response was so marked. Headlight out was not a road legal option so got rid of the HKS system and stuck with stock. Why spend £ on a kit then £00 on a cool box when the stock item works well. I admit the noises were fun, but as Chris has pointed out a what long term cost. It's all a bit Lax Power really. :flame Dev Link to comment Share on other sites More sharing options...
Guest mark_bond_007 Posted October 16, 2003 Share Posted October 16, 2003 so u telling me an induction kit is a bad idea then? I'm only bothered about the noise, cos standard my car is really quiet unless i'm hitting the redline! is there a better way to make the car sound more powerful? and is there anyone with an induction who fancies swapping it for my standard air box seen as the standard one is SOO good?!

JamesG Posted October 16, 2003 Share Posted October 16, 2003 Originally posted by Chris Wilson My Skyline R33 GTR needed new valve guides, a rebore, pistons and rings, all the valves re seating and 2 second hand turbos due to (IMO) poor filtration. I run F3 engines, which run with no filter at all, so I know EXACTLY what unfiltered air wear looks like... Very interesting. I hadn't realised poor filtration could cause such serious problems. Chris, I'm sure you've noticed my car has a HKS mushroom filter which was on the car when I bought it. I do really like the sound it makes, but perhaps not at the expense of engine reliability. I might have to look at getting a standard airbox sometime. James. Link to comment Share on other sites More sharing options...
womble Posted October 16, 2003 Share Posted October 16, 2003 Hi Mark, I'm far from an expert on these things but I'd have thought your first and most effective mod to achieve what you're looking for (nice noise) with the added benefit of a bit more go would be a nice new exhaust system, I'm sure some of the other N/A guys on here will be able to confirm either way.

Guest mark_bond_007 Posted October 16, 2003 Share Posted October 16, 2003 Well an exhaust could be a better option, mines the TT though not the N/A. Does anyone know a good exhaust that'll make the engine sound really powerful without having to spend a fortune?! Link to comment Share on other sites More sharing options...

Roy Posted October 16, 2003 Share Posted October 16, 2003 looks like the moral of the story is : if you want reliability and good filtration - stick to the original airbox. if you want flash sound n engine bay at the cost of reliability - buy an aftermarket induction kit. YOU HAVE BEEN WARNED !!!!! :flame Dev ( ... p.s. i've got a blitz SUS unit and a heatshield and am getting a cold air box - but then i never said i knew anything anyways!)

Soonto_HAS_soop Posted October 16, 2003 Share Posted October 16, 2003 I may of stayed with the standard air box, but then I saw the carbon fibre coloured light, and I had to get rid of the stock black plastic. Ben.. Link to comment Share on other sites More sharing options...
