TaylorMade Speed Injected Twist Face Explained
TaylorMade’s Tomo Bystedt explains how the Speed Injected Twist Face is tuned to create even more ball speed on the new TaylorMade M5 and TaylorMade M6 drivers...
How does the speed tuning process work? After the grinding, painting, polishing etc of the head, right at the end of the process when the head is basically finished we CT test the face. Hopefully they will all be slightly over the limit at this point. We then enter the data into a computer through a programme to determine how much resin needs to be injected into the heel and toe ports. The resin then cures (hardens) and we measure the head again after the speed tuning process to make sure it’s right on the limit.
What CT are you targeting with each head? Obviously we want each head to be as close to the limit as we can comfortably get to. Different CT machines might produce different readings so we need to be careful, it’s not going to be on the number, but it’s going to be a lot closer than the heads we’ve made in the past.
Do you CT test different points on the face or just the centre? Not every club goes through the multi-point test on the face, it’s only about one in 20 heads where we CT test different parts of the face. Most heads just get CT tested on one part of the face.
How does the resin slow down the face? Resin is injected as a liquid but once its cured it hardens and can then resist some of the flexibility in the face. So it’s really just tightening the trampoline effect to reduce the flexibility just enough to make it legal under the Rules of Golf.

With different amounts of resin going into each head, will the club weights and draw/fade bias be different in each? No, the draw/fade bias won’t be affected by the speed tuning process and while there will be different amounts of resin in each head, it won’t be enough to affect the swing weight and we have other processes like hot melt to make sure we get the head weights the same.
What about if your ball strikes the face near or on the screws themselves? The durability of the screws was really important for us and we have done a ton of testing and not seen any failures. We’ve if anything over engineered them so they will stay in the club and not affect performance.
Can you take the screws out and alter the resin? It’s actually impossible to reverse engineer this process. The only way to get the resin out would be to destroy the club completely and the ports themselves are impossible to remove as well – you’ll rip the screw threads just even trying to undo them so they’re not going to come out.
