  • Out running my GPz750 Turbo. Fresh from Roger Twito's shop in TN. New billet turbo wheel, ZX oiling upgrade, rebuilt clutch pack, among other things.
    Mods: 810cc Big Bore Kit, GPz1100 intakes, Intercooler, HKS Relief Valve, DynaS ignition, Racetech Rear Shock, Fork Emulators, EBC Brake Rotors, Race Mode Enabled, Cosworth Widened Rear Wheel, Custom Exhaust, probably some other stuff I'm forgetting. Dyno sheet before upgrading the turbo, showed 184 RWHP at 165mph.

    I have an 85 turbo. I cut the boost cut off wire going into the ecu. Put an adjustable fuel pressure regulator, bypass valve in charge pipe, cut the turbo pipe 9” after the turbo, jacked up the fuel pressure and now running 18psi on 110 octane. My bike flies !!!!! I’ve had my bike since 1990. Do you remember Mike Chestnut ????? He was a real whiz on these bikes !!! Great guy to have known!!!!!!

    these were such a nice bike to ride. full of muscle and grunt, sat like a brick on an ice skate like rock solid, comfortable enough for long rides but at speed that wouldn't be long coz of the small tank so fill up every hour or less... it never failed to put a smile on my face and always handled with a real sure feeling. something many other bikes of the time lacked.

    I had one (1985) it was scary fast you could crack the throttle in fifth gear and the front end would come right up for just about as long as you can hold it. I did almost drop it my very first time driving it my left hand came right off the grip as the front end came up I barely pulled it back to straight just as it was coming down my heart was in my throat pounding......these also are very rare bikes they only made 1500 for 2 years 1984/85 and they are numbered in sequence.....

    You say that before upgrade the hp was 185, what was the setup then?
    How you control fuel with more boost? Power commander?? Is the ECU flashed??

    • @williamrobertson8962
      @williamrobertson8962  4 роки тому +1

      It’s making about 20 psi. I didn’t build the bike but I know it has race mode enabled on the ecu and Dyna ignition. It was turnkey tuned when I got it. The set up before was the same minus some tune up items, viton clutch dampeners, and billet turbo wheel. Roger Twito in gallatin, TN is a pro on these and Charlie Evergreen Turbo in FL is your turbo guy. Finally, 750turbo.com forum is your friend!
