Did you have to flow it or was it good to go as you recieved it?? Also does it flow better than the end fed log type plenums?
Mark had the Hart cleaned up by his head man as its a bit rough as supplied. On the same engine Spec it made 47bhp more than an RS500 plenum which had obviously reached its limits. Certainly the equal of the MIS at these levels in fact i believe it made its Power with lower boost than Daves when on the same Turbo.
