Great session on the dyno with GBS and their Mazda powered Zero.
Ian brought his Millington DS2+ powered Mk2 for full mapping. We found power top end and mass amounts of Torque between 3,000 - 5,000 rpm. Gorgeous car. Mapped by us on DTA ecu . Listen to her sing
Yup she is as low as a lawnmower! We recently had the absolute pleasure to dyno this stunning Hot Rod. Absolutely stunningly well prepared car. Listen to her sing
The sun is shining and these beautiful machines are out in force. This is a Mazda MX5 powered GBS Zero with Emerald K6 ecu in for full mapping. Listen to her sing
Class 6 Autograss race car with XE power. Full dyno mapping, stump pulling torque. Mapped by us on ecu. No bouncing, jumping or inertia runs just a controlled loaded run. Listen to her sing
Stunning RSR Mk1 with 300 BHP Duratec in for diagnostics and map clean up. Pleasure to work on . Mapped on MBE 9a4

The simple reason for larger ports, valves and cams is to increase air flow. Any restriction at any point will diminish any other improvements as that becomes the limiting factor and in this case the restriction in air flow.
We have this cylinder head in for improvements as was ported elsewhere. It has +2mm valves and new valve seats.
We have re-cut the valve seats and increased the size of the I.D of the valve seat. This allows greater flow around and behind the valve ( taking advantage of the larger 35mm valve).
BUT as you can see it has left a large step where the original valve seat was, demonstrated the flow restriction.
This will of course be rectified before we rebuild it for our customer.
This is by no means a criticism, it is a message about where gains and losses can be found. So if you want to get the best out of a 35mm valve then don't put a 30mm hole / restriction in front of it.
