18% may be a touch high - however, I can relate J.K. Jackson's story and
numbers here. He had a TR-6 on a chassis dyno and ran it with the fan,
then he removed the fan and remeasured. Simply removing the fan gained
him 13% more power on a TR-6 engine. The TR-6 fan is plastic rather
than metal like the TR-3/4 fan, but it has more blades so those probably
balance out a bit. Therefore, I'd guess that a TR-3/4 should see a
similar performance gain as the TR-6 did.
I hope that helps,
