Stay tuned

Off to the races... Heading out to Phoenix on Friday for the SCCA Double National at PIR. The Honda I was racing against last season is on the entry list, so it should be a good battle.

Built a new intake system to test. The car came with a K&N short ram system that had a built in velocity stack. I have never seen one before, and looking at the finish on the piece I believe it was a custom CNC piece from the cars previous life. I had been kicking around the idea of trying it, but the setup needed some fixing. The short ram lacked a breather input (the hose was laying loose in the engine compartment), and from what we have seen on the dyno the Yaris likes a long tube intake - makes better Tq.

So I ordered up some tubing, clamps and a breather filter so we could give it a go. This setup gives us about 6" more tube length than the off the shelf K&N system we were using. It also has a larger diameter filter, the velocity stack, and none of the baffles for the MAF.

We will try it this weekend, and next time we go in for a tune we will run them back to back on the dyno.

I still need to get some heat wrap for it.
