Eat this 2 Posted September 13, 2008 Report Share Posted September 13, 2008 what were the wheel figures mate? Link to post Share on other sites
Guest pro-biotic Posted September 13, 2008 Report Share Posted September 13, 2008 just trying to scan the printout - 3 vista machines and an old scanner dont mix...------------------------engine power measured . 158.4@106mph / 5688rpmwheel power measured 140.8 @106mph 5688rpmpower losses 17.6 hp @106mph 5688 rpmengine power 160 @106mph 5688rpmtourque 163 lbs/ft @4320 rpmpressure/temp 997 mbar/16degrees Ctest conducted using SUN dynomometer...as i say as soon as i get one of these vista machines to dual boot ill scan a copy of the table Link to post Share on other sites
thegoth 5 Posted September 13, 2008 Report Share Posted September 13, 2008 rest assured, 140 at the wheels is about right17.6 for the transmission lose looks very wrong, usually more like 40-50.giving a flywheel total of 180-190torque maybe a bit low which I'd credit to the exhaust.

Guest pro-biotic Posted September 13, 2008 Report Share Posted September 13, 2008 so u reckon its running reasonably well?by exhaust do you mean the lack of ack pressure? i belive it is a 16v scorpion straight through with std manifold.is the figure of 17.6 something the operator inputs into the machine?

Guest pro-biotic Posted September 13, 2008 Report Share Posted September 13, 2008 Our 500bhp rolling road installation has recently been upgraded to a Sun RAM 3000 with diagnostic and data aquisition systems, providing accurate power and torque curves with full temperature and barometric correction. The new system also provides much-improved data printouts for the customer http://www.balmuirgarage.co.uk/rollingroad.htmmrgoth so your saying its the losses from the transmission the higher the number the more losses??sounds like this parameter wasnt setup correctly then...worth a trip back armed with info?

Eat this 2 Posted September 13, 2008 Report Share Posted September 13, 2008 worth a trip to a diffrent rollers mate17 hp tranny loss where the hell did they pluck that from? its normally about 18-20% for fwd car Link to post Share on other sites
Guest pro-biotic Posted September 13, 2008 Report Share Posted September 13, 2008 cheers again guys. at least i know not to go forking out on bits. thought it was quite odd as it likes picking on civic type r`s and generally sticking to them like glue.just spotted a leaky flexi joint on the downpipe.. so a few more pennies to spend.
