Quoting mitsuturbo:
Not sure if you already know this, but just FYI, if you set the HP drivetrain loss to ZERO and play with the smoothing settings you can get results much closer to actual WHP. The drivetrain loss default is like 20% IIRC.
Yeah, Iv been kinda judging my results/mods against the DSMlink HP calculator for quite a few years on all the cars Iv run it on...and regardless of the actual absolute #, (just like dynojet #'s), it's all about the comparison of changes. in back to back logs. Im far less interested in that it says 400 or 500 or 300.....than I am that it picked up consistent 15-20% power with the meth vs the best power I was able to see on straight pump 93.
The settings are spot on for RPM/MPH for each gear. Im estimating 3400b total weight. The drivetrain loss still set at 20%. I run the two smoothing settings at 8 and 6 respectively (I think defaults are 4/3).
Im going to the dragstrip tonight to Test & Tune...the ET/MPH will show the results for sure:
The car went 12.3@112 on it's best run last time (pump gas only). 27psi boost. Very low timing (curve like 2* to 7*), AFR in the mid 10's. Knock pretty bad in 3-4 gears. Link shows 400hp peak in second gear and 350-360's in 3rd gear due to less timing/knock.
Now Im seeing it hit 495-498 repeatable in second gear. and 485 in third gear. 30psi, no knock, timing 12-17* average, mid 11 AFR.
Im very confident the ET/MPH will be quite a bit better. /ubbthreads/images/graemlins/rofl.gif
One of these years/months, I need to take the car out to Vinny Ten's shop in long Island w/ GizmoVR4 and run this car on the dynojet and get a comparison of "real dyno" vs DSMlink estimate.
Overall, I think the Link HP estimate has been very reliable/indicative of actual reality at the dragstrip. When it shows a power gain...the car goes faster at the track. /ubbthreads/images/graemlins/devil.gif
