THIS MONTH I HAVE MOSTLY BEEN… “Finding extra power.”

After all the bother I went tolast month fitting the Power Commander V and Secondary Fuel Module, I thought I’d try and make the most of it by getting the thing fuelled properly. We decided to van it down to see the boys at JHS so we took along the standard exhaust and an Akrapovic secondary and end can that I’ve managed to get hold of. The idea was to have a little head to head power test with the Austin Racing exhaust that I’ve been using for the past few months.

It’s all well and good testing fancy exhaust pipes, but I’ve always thought that you can only blow stuff out as fast as you can suck it in so with that in mind I had a real good look at what trick air filters were on the market. I ordered myself one from DNA High Performance Filters and rammed it into the air box, in place of the standard one. Easy-peasy, lemon squeezy.
