So i finally got round to fitting the gold leaf wrap to the intake and heat shield this weekend. Thanks to Cali for help!
So we did a pre-gold DL at 22c during early evening and took a route which involved cold start, 30/40mph part throttle runs, 50/60mph part throttle runs with some low gear/high RPM stints and some VTEC upto 80mph both 3rd and 4th gear pulls. Route took about 40mins and we saw a consistent relationship between engine coolant temps and intake temps throughout the run often showing temps like 100F intake and 180F engine or 108F intake and 197F engine and so on.
After fitting removing the intake and heat shield and applying the wrap we our outside temps had dropped by 3C over 1.5hrs so we didnt DL and left it to the following day. Waiting 24hrs we waiting for the magic 22C and carried out the identical route from cold start carrying out the identical speeds and revs as before.
Our results showed that the lower the engine temp or MPH and little difference maybe 1F lower. The 30/40 showed 3F difference and the 50/60 showed 6F improvement. When we got to the 80MPH run we were now seeing an 9F improvement for example our 197F engine was now only a 99F intake
It's unfortunate that we didnt do a base DL with 100MPH and maybe some hard A road driving as if the multiplying factor continues to strengthen as we see from 30 to 80MPH and engine temps we could see even more of an improvement!
Next steps will be to wrap the hot water pipe which sits directly under the intake pipe to see how this reduces the intake temps further and then maybe even a ceramic coating on the buddyclub manifold but all steps will be done one at a time along with same route at 22C.
