Tuning Rough draft spi bob

Would be interested to see that. Although having checked my system after a 15mile run this evening to find that my Bob and intake pipe are ice cold I don't think it's a issue but crack on :)
 
Plus if your going to go through the hassle of modified air filter and a scoop why not just stick a cone type filter on top of the TB and have it poking through the bonnet :D
