I know this has been claimed before and there might even be several dyno graphs floating around somewhere, but I thought I would provide an update on what something like a UAS pipe alone can achieve for the FTO even using the stock airbox.
I know the below info is nothing new, but with some of the questions I have seen floating around the forum lately I thought I would put up some solid input.
After cutting down to size, the pipe will fit perfectly with the stock airbox. First step for me will be to get some black spray paint out. Hate the red.
My before run showed my bone stock GPvR punching out 98.9FWKW in third gear (4th gear hits the limiter
) which I was acutally pretty happy with. I was expecting something more like 90.After fitment and retaining the stock airbox, this pipe is good for about 3-4FWKW. So I'm now punching 102.6FWKW, although the difference is only really noticable in the upper rev range.
Bigger gains could probably be had with different intake setups, but personally, my next step will be to cut a 3" hole in the bottom of the airbox and run a nice thick bit of rubber pipe down to somewhere near the radiator mouth.
