did you do the run-in procedure as per the manual prior to dyno run
awesome work nonetheless
Go titan motorsports
now the real fun begins!
Can you tell us when you have this tune available?
Stock Dyno from Real Street
Holy shit so if you were to convert that to crank hp with 10-15% drivetrain losses that's hitting approx 410 hp and 460 lb-ft?
10% would be a more conservative estimate considering what we've heard about this transmission. But yeah, we knew the numbers were high from the C&D dyno (also dynojet), though quite a bit lower then what they saw. Which there was some speculation was from tranny slip, but the dyno didnt really show signs of that. Would be nice for someone to do a reliable 0-60 test on a car that's put 380ish torque to the wheels and see if they can back up the 3.8s. If not, the press cars may have had more aggressive tunes.
You would add 10-15% for the HP but not the torque, that doesn't change.
Interesting. Can you explain why is that? A lot of people also calculate torque as well. Why is this an exception?
because torque is not lost from engine to wheels, it is multiplied - through gear ratios, wheel diameter, final drive ratio and (if fitted) torque converter.
This was shared with me earlier today
When HP is a derivative of torque, you can't change one w/o affecting the other. Remember, HP=(Torque * RPM)/5252
Yup so theres that.
Incorrect. MA671M is half right, but the dyno software takes that into account. Read this, it will clear it up better then I can (it's a PDF you'll have to dl)...
Thanks guys!! I appreciate all your explanations!
Dyno numbers are best analyzed relative to other cars. Are there any other cars that were dynoed by the same people?
