JohnK Posted July 15, 2005 Author Share Posted July 15, 2005 The inside of the airbox is insulated with the same material as my turbo blanket is made of, glassed into place. So it should provide a good thermal barrier. Link to comment Share on other sites More sharing options...
JohnK Posted July 22, 2005 Author Share Posted July 22, 2005 Right some intial results from the airbox, although please note it is NOT completely sealed - yet. Temps seem to be kept to around 5c above ambient and it takes a lot longer to heat up in traffic. However it does still heat up to around 50c when stopped in traffic for a long time or when stopped for The only problem I have found so far, is that it seems to take longer to cool down once moving. I will seal the box up more tightly when I get the chance and see what improvment that makes. Link to comment Share on other sites More sharing options...
Prof. Monkey Posted July 22, 2005 Share Posted July 22, 2005 Why are you not measuring the temperature on the move? I got a little thermometer off ebay, that cost a few quid and has a probe on a wire that can fed into the engine bay. Obviously as a scientist, I would look at both temperatures at standstill and whilst running, when colder more dense air is being sourced from outside. I bought a grille from http://www.grille-tech.com Cost me £40.00 for the standard supra one, fits with some zip-ties (which is only temporary whilst I source some long bolts) I then spent £15.00 and bought a pipercross, cold air feed, from ebay - which includes the intake trumpets. Drilled holes in them and fitted them to the grille and offered the whole thing up: after a bit of faffing about it all fitted well. Now then, as I am using an N/A supra all the plastic work was removed (where you would normally have intercooler pipes) I fed the flexi-pipe into the engine bay. There has been a change in performance, I have been using the Injen Intake for a while so I could justify the improvement. The throttle is a little snappier and it seems to pull better.

JohnK Posted July 22, 2005 Author Share Posted July 22, 2005 I AM measuring the temp on the move. Also intake temp isnt as critical on an NA and I would also venture to say that the under bonnet temps dont get as high on a NA. I also aim to prove that a sealed airbox is the only way to go and that bits of pipe, so called cold air feeds, are as good as useless. Link to comment Share on other sites More sharing options...
Prof. Monkey Posted July 22, 2005 Share Posted July 22, 2005 Interested to see what your findings uncover... Link to comment Share on other sites More sharing options...
