Same car, nothing changed 2 weeks difference, 2 graphs:







I know all rollers are different. But how can the difference be so big?

 

Because Superchips Dyno notoriously over-reads.

 

As above, try to look at rolling roads as a tool for tuning. Put generally speaking DD rollers are accepted as the most accurate.

 

Well theres no way my car is 146bhp. But you're right in saying use it as a tool for tuning. My engine is soon to be taken out and rebuilt so will be good to get it back on when its all done. But I cant see how they can be 17bhp out.

 

As above - different dynos and different results on different days... thats how it is!

 

the second one is in the middle of nowhere,the cross over point is even in the wrong place!!!


cheers danny

 

Cross over point wont be as the scale are not equal....

 

graph is spot on if you check the outputs for 5252 rpm, there equal

 

For someone thats done over 1000 RR runs, thats a pretty fundamental over-sight!

 

oh yeah should of looked closer....
still in the middle of next year!!!

cheers danny

 

sorry mate i dont suppose youve ever had an over sight?????

SHOOT ME DOWN....


cheers danny

 

Easy tiger!! Was just a bit of banter.

 

sorry should have had a lol in there

lol

cheers danny

 

and add into the equation guesstimates of flywheel power. They're always going to be miles apart.


Use wheel figures, there is less manipulation with them.


Although either way, take all figures with a pinch of salt. All that matters with RR numbers is before and after when tuing on the rollers. The rest is purely pub talk.
