hi dears,
I got a ´01 busa with turbo with demaged head gasket.
motor data
cylinder big bore from dia 81 / 3.189" (orig.) to 83 mm / 3.268 "
complete MCX400 turbo kit
compression reduced from 10.5 to 8.8 : 1 (by thicker foot gasket)
turbo pressure max = 1.2 bar / 17.4 psi
test bench showed about 380-400 hp (at 378 km/h ~ 238 mph the test bench "said" stop ::-) )
orig. ´99 radiator + his fan
the situation now is :
gasket is changed and I made a - naked - test run (without both side panels)
result:
the bike´s pointer stays at bit under the middle of the diplay even after 20 minutes running (in/at idle) in my garage.
then i let the busa cool down to room temp. , mounted both side platics and let it run again with the result that the pointer now went up beyond the middle line
and i stopped the busa that moment.
then I dismantled both side panels again and a day later the owner made a test ride for more than 100 miles (& over 190 mph)
result:
not even a minor prob. - nothing - the pointer even stayed a bit under the middle line (temp. outside ~41°F) what ever he did - slow driving ~25-30 mph inside town / highspeed > 180 mph on the highway
damn - what now?
my idea - the, one, original fan on the left side seems not to be sufficient - so a 2nd fan should come, becaus the busa´s temperature runs perfect when busa is "naked".
but this brings me to another question - which one with which dimensions in terms of height / thickness and diameter?
so do YOU have any (other) ideas and/or poctured solution 4 me?
heeeeeeeeeeeeeeelp !
thanks :-)
