Re: Andrew's 1999 Turbo RAV4 project...	Tue, 05 August 2003 14:45

Last weekend I ventured up the North Coast once more to partake in the outdoor car show event that last year won me a trophy. With my RAV4 looking very ordinary this time last year, a LOT of stuff had been done to it in time to make it for this year's event. As expected, word had got out that the Asian vehicle category was an open doorway for virtually anyone with a modified rice-box to enter, as I'd done last year and basically been awarded a trophy for getting out of bed and showing my ride. There was 4 times the amount of competition there this year, yes that's right... 4 Asian cars (count 'em...) were in the judging for the trophy. A trophy would have been a bonus to me, but the main reason I went up there was more for exposure and to let everyone know that HAD known me with the RAV4 before I moved to Sydney, that it was getting to be something to take seriously. A lot of people took notice of it and admired it rather openly, even though I didn't take home another trophy. A Nissan 180SX took that home, although if I'd had a stereo system with some custom checkerplate in the back end, it would have been a close decision. They were really the only differences. Anyhow, before the car show, my dad and I went to work on the ram-duct install to assist the cold air intake with better breathing. We removed the resonance chamber (the last remnant of the stock airbox system) from behind the bumper. It takes up a surprisingly large amount of usable space that can be used for ram-ducting. A portion of the bumper was cut out, as the bashplate attached to the grille-guard was taking up the other available space, and I didn't want to cut that part out. After the cut-out hole, the mesh-covered speaker port, masquerading as a ram-duct entry flange, was installed. The tube was hooked up to the entry flange with a 3" hose clamp. What the flange looks like now, installed on the bumper. The tube was run up through the engine bay, behind the left headlight. This is where it got a bit squeezy. Part of the tube had to be slightly flattened (oval shaped) to accommodate some of the wiring that was there, and the headlight connectors. The tube runs in behind the indicator/parking light assembly with no worries. After the last part of the tube (the exit side) was zip-tied into place, the K&N filter was replaced and the setup now complete. The idea behind this is; because it's not a direct suck-through system (like on an ordinary 4WD with a snorkel), the air has to be drawn up from somewhere so the intake can get at it and draw more in on demand. The principle behind this matches the needs of the CAI at virtually any speed. The air is pushed in through the flange at speed, driven up the tube where it exits into the heatshield area, which is closed off to the rest of the engine bay. The cooler outside air taken up through the tube first hits the intake temperature sensor before being sucked up by the filter. The ECU then controls the engine's A/F settings to combust the mixture with cooler, more dense air, making for more a more complete burn, better responsiveness and better economy. I'm glad this part is out of the way, as it solved the 'where to put it' problem that existed for months before I attempted it on the weekend. Credit goes to my dad as well, who helped out a lot with it. Next on the to-do list is a replacement fuel filter... these babies last 80,000 km's before changing over.
