Wait, maserom, you mentioned at the beginning that you had a baseline of 208 with runs of 222 and 224. These are a bit different, what happened?? This is important, cause the one you mentioned in the first post was a 15whp for an auto, pretty good, better than 13whp on this graph.

What a crappy automatic!!? It was in 3rd. REmember only 1,500 miles on this motor. A more worked in engine will give higher #'s

I've never seen a graph look like that. It looks like the stock curve was just shifted up 10 hp like an excel function did it. The results are so uniform throughout the RPM range.

Well sorry, but as much as I want to believe your results I just can't because you got your car dynoed by Borla. The same reason why I would not believe a dyno for a Stillen exhaust made by Stillen.

Anyways...this is a very valid point if you REALLY think about it. And if you look at my sig I have this exhaust too.

Maserom, Importriders is one of the few people I've met who will do a baseline dyno followed by the dyno after install at his own expense for our good.
So, in short, give the man the respect he has earned because he's doing it right and we're all watching what he's doing and what you're saying.

Question...
Why was your Dyno graph only run up to 100 mph? Surely that can't be 6600 RPM?
I had my Baseline Dyno done and I know the Speedo registered in excess of 140 mph...
(OK I may have now realized that this was done in 3rd gear and could be the reason for the low speeds. I'd like to see a HP and Torque curve vs. RPM not speed)

well, here is a thought: isn't it another possiblity, just a possibility that the only reason we are seeing a gain is because they purposefully made the baseline dyno numbers low somehow? what do u guys think?

I am by no means a duty expert on dynos at all. As a matter of fact, I've never had one done. I would expect that they could get the date right though!! However, if this date is correct, then none of this make sense to me.

That's not really a big deal. If the computer running the software has the wrong date (which it might being that many of them are old and their clock battery may have died) then the date will appear wrong on the printout.
What irks me more is that the gains are unform all the way through the rpm band. The results look like they were smoothed way too much or doctored.

I can believe the peak numbers, but the dyno graphs don't seem possible (although I hope they are true).
The reason they seem unlikely is because, as others have mentioned, the gains in HP seem to be very similar throughout the RPM band. Because HP is dependent on torque X RPM, this means that the exhaust would be making huge amounts of extra torque down low, while making less extra torque up high in the RPM range. For instance, at 40 MPH the HP gains seem to be similar to the gains at 80 MPH. For this to be true, you would need to be making double the added torque at 40 than you would be at 80. I would love for this to be the case, but most of the other Borla dynos (and exhaust dynos in general) have shown the gains to be greater in the higher end rather than the lower end. Therefore the results are a bit confusing to me.
EDIT:
If this works, then below should be throbbing_zon's dyno results. They are an example of what I would expect the HP curve to look like.
END EDIT
Maserom, I am very grateful to you for posting the results and giving us an opportunity to check them out. Please realize that I do not question your integrity or expertise, but only the fact that this dyno differs from most other exhaust dynos I've seen. With the limited amount of data available, any added information is greatly appreciated, so please don't be discouraged by my questions. I'm an engineer; I just can't help myself
. I truly like the Borla exhaust, and appreciate your effort in this matter.
Thanks,
D'oh!

the reason the dyno might look different is because the dyno uses mph as its x-axis. layoff this guy and look at the damn thing. that is definitely why it is so linear.

The bottom line is, I love this exhause. It is the first mod i've done to this car that has resulted in a noticable power increase. It sounds great! And has provided me with complete satisfaction. I know nothing about dyno's. I say the dyno sheet come up on the computer immediatly after each of the runs. They appear exactly the same as they did when they ran the car. These guys have been dynoing cars for several years. I trust their workmanship and integrity 100%. It seems to sound better each day.
