In my opinion, it’s important to not get hung up on the figures really. (Yes I know it’s nice to say I have this or that).
Clearly, BBR use the software program to convert the WBHP/Torque to the figures people like to hear. OR they come from a actual engine Dyno?
Your print out would not be the latter for obvious reasons.
Those 2 graphs are not really consistent. As the blue lines show the original engine graphs which are completely different for the 185 and the 200.
In other words if both blue lines on the graphs represent a “standard engine”, I would expect to see both blue lines being the same, (they are not).
The Red lines would obviously be different because of the different parts used, (as pointed out).
Let’s be honest BBR (or indeed any other tuner) are not going to provide graphs that are not consistent with the packages on offer.
Probably, all Dyno’s will provide different readings for the same car too.
As an example, my graph only provides Wheel BHP and Torque. As he said you can’t measure the crankshaft figures on a chassis Dyno.
I had 4-1 IL header.
Skuzzle Torque Intake.
Standard centre pipe and cat.
Cobalt Rear Box
Remap.
I watched for a good 50 minutes or so the remap tuning, because he wanted to get the curve right with no dips or troughs…
This is all done on the Chassis Dyno with a 1:1 ratio i.e 4th gear and at 7400 RPM.
The end result was 153.2 WHEEL BHP with a 137.0 FtLb.
To actually convert the WBHP is 137 x 7400 RPM = 1013800 ÷ 5252 (The mathematical figure) = 193.03 BHP.
Whether it actually is , is another matter of course.
But I reckon the extra 8 does come from the Torque intake?
Believe it or not the remap actually gives me better MPG too, (Have proved that).
I’am not a betting man, but I know you will go with the 200!
Enjoy.
