fter months last year testing the demonstrator from RRG Toyota Macclesfield with Richard last winter, this time, I’m driving his car. Richard has done quite a lot to his own car and it has carried on the mantra from the demonstrator of testing new tuning parts. A year down the line, there’s many more options for the GR Yaris and this is particularly so with induction kits.
Richard has fittest the new ITG induction kit, which comprises a pick up from the front grill, then an enclosed cone type foam ITG filter which then feeds into the standard inlet.
The thinking behind this is that with the OEM setup, there is an open tube that feeds into the airbox. It is a complex setup with a flap that opens at 3500rpm to allow a greater amount of air into the airbox, though this air has to travel through the engine bay to get there. Now, I should add that there is a specific vent from the front grill to direct air in the general direction of where it would receive the air when the flap on the airbox is open.
The problem has been, of one of heat soak, particularly so at low speed and in hot conditions on the track. The ITG induction kit is designed so that the only air the engine is received is right from the grill with no chance of air from within the engine bay being sucked in.
Richard also has a stage 2 DTUK tuning box, RS Fabrications exhaust, CAE short shifter and a Turbo smart dump valve.
Upon driving down the road, the comedy value of the Turbo Smart dump valve is hilarious well, for me at least for the first ten minutes. I have to say it’s a matter of personal preference, which is not mine. I can say the same of the short shift kit, it’s not my thing, but I know others love it.
Once Richard has selected a more torquey map, there is a bit more meat in the midrange torque compared to my car which runs a stage 1 box, Cobra exhaust and ITG panel filter. The difference is not dramatic though as one might expect.
What I’m noticing albeit on a bitterly cold winters day is that the intake temp is a lot more stable than it is with the stock setup. I can’t say that I’m feeling a big difference in how the car picks up and goes, but I feel that this new induction system, is going to reap further benefits on a hot track day or on a serious pass up the Yorkshire Dales in the summer. I also think it will help when sprinting as there is a fair bit of waiting on the line which is not good for heat soak.
