Is the hole for the washer fluid tank big enough for an air intake tube without cutting?

 

no

 

What size hole do I need? 3"?

 

Well I went with 3" aluminum dryer tubing It sits right below my cone, and exits in the wheel well (took the washer fluid tank out of course). When fully warm I can smoothly run all the way to redline, which I couldnt before. I would lose power at about 6k. So, I think its a success. Now I just need a box to isolate my cone

Oh. And I dont have a digital camera so cant post pics

 

3" should be cosidered a minimum duct size, so you'll need a hole slightly bigger than that.

 

try not to go past redline to much killer or you will be posting "my engine does this hissing sound and puff out smokes like crazy and doesnt turn on"what should i do
