Induction kits - utter shite, air temps far too high

Ive just checked the temp around the air filter after a 5 mile trip, never booted it in that time and I didnt get stuck in traffic.

59.1c !!!!!

Im on a mission to refit the stock airbox.

I am currently looking to box in / re-position my K&N filter too.

I ve got a K&N at the moment but thinking of a K&N panel filter for the stock airbox. How exactly did you check the temperature???

Engine off, opened the bonnet just with the interior catch and fed probe thru to where the filter is.

Engine was off approx 1 min, would have been hotter still with it running!

I just fitted a turbo blanket in the hope that I can get the temps down a bit, I had steam coming off the bonnet in a queue for a recent event which made me realise how hot it must be getting.

Let me know if you find out how to box it in. Not sure if the stock airfilter flows well enough for a single though..

Branners, I have a super dooper turbo blanket that I can actually hold my hand on while its running. That is only part of the problem.

Following a recent conversation with Chris Wilson and subsequent advice given, I too am in the process of refitting the standard airbox.

I think Dusty has a airbox that K&N can be shielded. Perhaps some additional pipework will be needed. From the pictures of the kit that Dusty sells - it's sits right behind the off-side front headlight, whereas the pictures I've seen of the budget conversion - the K&N filter doesn't quite reach that far.

Or am I talking bollox ?

lol, im one of the lucky few who got a stock airbox when i got my car! Put a K&N Panel straight in...

Ah, but we are talking about single turbo cars here

You are not talking bollox. Dusty is due to sell a new air box assembly specifically designed for single turbo converted cars. The trouble is, it has been muted for months and seems no closer now.

If anyone is looking for a stock airbox, I have prices for NEW ones from here, they are not cheap, but they should be a lot cheaper than from Toyota UK. Give me a shout if you want details.

From Dusty's webpage:

''Max Air'' Air Box for Supras with an Aftermarket Intake Other than the HKS or with a Single Turbo

http://www.mvpmotorsports.com/Images/spacer.gifThis kit includes the Max Air air box without a precut hole for the intake. This can be made to fit any single turbo or any stock twin Supra with an aftermarket intake that routes into the usual air-box space. THIS KIT ALSO INCLUDES THE HIGHLY RECOMMENDED THERMAL WRAP. Your Price$184.00

If you look at pic 2 http://www.mkivsupra.net/vbb/attachment.php?attachmentid=15536, I am going to extend the pipework and cut a hole into the metal below the filter and drop it down there. It will allow me to get cold air in whilst blocking the hot air from the engine.

Ah interesting idea. Would like to hear how this pans out Colin.

I remember the angry and contemptous posts aimed at me when I 'dared' speak out on the subject.

Better late than never though, eh? lol...

But we are talking about single turbo cars here John, not TT's.

What is the difference then?

Your posts were all about changing the stock airbox for aftermarket filters. The single turbo users didnt deliberately do away with the stock air box.

The advantages of the 'cone' filters are grossly overstated in general. As a result people find it preposterous to have a single and retain the stock airbox (which is what I'd do if the SMIC space was not available)

I've had temp probes in the engine bay (datalogging the whole inlet tract) and during summer days the figures can be scary, especially after a couple of good runs.

Exposed cone filters only look good in shows with the bonnet open. They sound cool too.

But the heat and grit they allow inside the engine is scandalous.

Tis nothing new - people have known for ages that the stock airbox is best. All I've done is fit a TRD panel filter.

John out of interest, did you actually check the charge temps during the 5 Mile drive, or just afterwards?

What 5 mile drive?

More than one John on here mate

Will the filter get enough air if you block off the engine bay though - I know we need cold air but surely you can't get enough squeezed through the headlights to fill a single turbo or even the twins?
