Almost broke 300whp... what a bummer :/

now just wait for everyone else to call :bs:

That's about right for a dynapack. They report higher numbers than roller dynos because they do not account for traction loss or rotational mass from the front wheels. Personally, I prefer dynapacks for their consistency.

Nice power curve OP. Did you use the same dyno for your baseline numbers? Would be interested in seeing the graph if you did. (2thumbs)

thats the only graph i have
 
yea that would of been the best thing but its alright i guess nothing i can do. (not working another 6 hrs to take that downpipe off lol)

No worries. Here's a dynapack baseline from Import Tuner in case you'd like to know (my baseline was also similar). Again, very nice numbers OP.

More proof that dyno numbers really are all over the place (i.e. the absolute numbers are meaningless).

298 HP on one dyno might easily be 268 HP on another.

If big numbers are important, go with Dynapack.

Don't any dyno outfits calibrate their dynos on a regular basis? It only took about 3 minutes to calibrate the mustang dyno I have use for engine tuning. Something isn't making sense...

QFT. Good numbers tho. If ya want high numbers, go with dynapack. If ya WHP, go with Mustang.

Not sure why this is an issue? Dynapacks measure at the hubs; there's no efficient way to measure deltas from the absence of front wheels.

I avoid roller dynos because of their variance. One little slip of the wheel can cause a 15-20 WHP spike in your readings. If numbers are really THAT big of an issue to people, just deduct another 6-8% from the total power.
