my 900se dyno slip for today :-) Posted by jak [Email] ![]() ![]() |
well here it is....
when I got the new head & chain on & corrected the breakup at 5500RPM
(driveability issue)the AF was heavily effected by the cylinder head problem weard for sure
I didn't get the wideband back on it before I dynoed so I burned like 4 or5
ECUs to get the AF strait :-(
once I did that I basically played with torque VS power to end up with a
broad power curve without trans crushing torque
pull one ws pig rich & 330ft lbs at the wheels
they have terrible fans there so adapting on the dyno these were the pulls I was happiest with showing higher torque VS higher HP changes I was working on
I know the changes shown look marginal torque VS HP
I was able to make like 330ish ft lbs & 260ishWHP at the torque end but never realy got the HP much higher then what you see here using safe knock detection (not forcing it)
I believe mostly because of IC temps & pre ignition kicking boost back
higher in the RPMs
retarding timing a bit may have helped higher in the RPMs too.....
I made about 2 more pounds of boost at 5500RPM on the road then on the dyno
so if I adapted on the road & ran in there I mabey would have made more
power who knows? mabey not.....
Im not a rich man & an hour on the dyno was all I could afford so there it
is
I would like to have seen more but all & all Im pretty happy the car is
running great
I wish you all the best
take care
JAK
