Hey sorry about that Mike :blush2: Was thinking about locally but you are right in that you would definitely have more experience in MINI porting than our local shop :cornut:
Some of the information I mentioned is high end intake porting service and reconfiguration that may require partial intake fabrication or complete intake manifold modifying which is highly specialized. To date I have not seen anyone on any MINI forum post information having done a balanced ported (flow ported) or fabricated balanced ported MINI intake manifold for an R53.
It is just too complicated for the net results to bother with. Now in Pro racing, they need to get everything they can while limiting what can be played with.
This is a good article on what would needed to be looked at, tested (with a channel for each cylinder) and then retested while racing.
Not really worth the trouble to do it right. If one cylinder is already lean, putting in more air hardly helps, so knowing what the issue is would be the first step to correcting it. Also, unless running constantly at the highest RPMs, the amount of improvement that will be enjoyed by a driver may be fairly small even once maximized. Probably changing length would be best for a DD, but again, who is going to bother.
That's why no one has spent the huge $$ to do this for a mini. Cost vs. reward.
Great post Nitro! I'm happy with how my ported/polished intake manifold turned out. As a whole with the top-end of the engine build -IMO- it was a necessary piece to the puzzle. I don't recall the cost off-hand, but it was definitely reasonable.
With the Ported Head, and the intake ports enlarged for more flow and better power, the interface where the intake and the Head come together is NOW a critical transition point.
The 'miss-matched' ports will cause turbulence and restrict flow. Smoothing that transition is the KEY to allowing all the power from your new Ported Head.
Anyone interested let me know.
