Drilled airbox

[JelT5]

as i've said in a previous post, i've ran possibly 5 or 6 (if not more) different types of air filter/intake & despite the scientific info against them my fastest 1/4mile time was with an open cone filter. & when you think that just previous to the run the car was sat in the fire-up lane collecting the heat from the engine bay just shows to me how quickly the cold air gets in so making no difference to heat soak at all

I totally agree Pedro, my fastest 1/4 so far is with a £15 open cone filter; no heat shield etc. I've changed to the BSR set up more to tidy things up under bonnet than look for any gain in performance; never thought I'd put aesthetics in front of performance...*hangs head in shame*

My next outing on the 1/4 (next weekend- Bitburg, Germany) might show up any deficiencies in the new induction set-up; having said that, there are so many other factors that affect 1/4 mile times...
