I just finished up this new Top End for Pete Browne’s Turbo Derringer powered T/G bike. When I originally built the engine, we used Pete’s old cylinder heads, but now it time to upgrade. So, I did a new set of Billet UPM heads just for his application. We here at HRP expect to see the Browne’s step up their performance here by the end of this year. Future plans are to go to the Gen-4 raised cam upgrade and Methanol.
