Hmmm, interesting...
The Rototest does a similar thing onyl differently. I'm wondering how FP's car will show on numbers once they get it on there.

well the mustang dyno info was very helpful...but what i still dont understand is how there could be such a difference in whp between the cars....is it just cause of the lack of a cat-back...? Also i wasnt clear on why the mustang dyno always factored in the weight even though the faq said that it was only necessary at the beginning like with a dynojet?

i might as well add, double check the cams are lined up properly (ie crank pulley is showing TDC and intake cam and exhaust cam marks are alligned). that could be a possible issue
Why is everyone obsessing about the dyno they're using? All that really matters is relative dyno numbers for his car on the same dyno over a series of mods.
In all the reading I have done, results from dyno type to dyno type (and even dyno to dyno of the same type) vary so much that there is no consistency.
As to why people would use the dynojet over the mustang. If it returns a higher number, wouldn't you want to read/publish that one as opposed to a lower number (especially if others use the higher numbered dynojet)?
I'd rather have the most accurate numbers than the highest number and when all is said and done, what matters is the gain from your mods as opposed ot the actual number. I.e. do a pre-mod baseline first, then add mods and get a dyno to see the relative change.

i agree. as long as you use the same dyno for all of your runs you will get good tuning info. the mustang dyno is a much more expensive but more "real world accurate" for tuning. magazines use dynojet because they are cheaper and readers would rather see higher numbers.

Actually what i really dont understand is why the car with cams has 94 and just an intake and exhaust have 101. I believe the 101 cause whether it baselines at 89 or 96 its still a decent gain. But for the cams not to yield much is surprising. obviously a cat back would really improve them. Then i would like to see a comparison. ALso have u guys raced...who won? ALso that dyno sheet kinda looks weird. Usually they have spikes and arent that smoothed out....

For the sake of those who haven't had their head under a hood for several years:
What exactly do you mean by "tuning" and what exactly are you doing when you tune your cams/cam gears, for instance? Every post we ever have on performance or FI has the little caveat at the end... "it's easy to get 297564976947693476 hp... with proper tuning" and then they just leave it at that. In all honesty, it sometimes comes off as a cheap way out when people pull numbers out of their nether regions and only have their own imaginations to back them up. This isn't what's happening in this thread, but I just wanted someone to come out and define "tuning" to the common folk.

As Justin said we havn't raced, yet. 
Well here's what's going on:
I'm having the cams checked this week to double check the alignment.
My spark plugs are 28k old, I doubt this would make much of a diffrence, but it's possible.
I will be buying KYMP5's axleback as soon as he gets his new on in. Shortly after that I will have a mandrel bent midsection.
After all those changes are made I will dyno again.
I still think my biggest bottleneck is the Exhaust. Like I said before, I "gained" 4 whp when they took the probe out of the tailpipe. That pretty much tells me exhaust restriction is the problem.
Just for s**** and giggles here's what other's have put down on a Mustang dyno: (thanks to Mazdacub)
5sp stock = 86 WPH
5sp with intake = 89 WHP
5sp with intake and ground wires = 89 WHP
Auto with intake, ground wires and exhaust system = 89 WHP
So overall I don't feel bad about it at all, I think mines was a normal dyno, and Justin just has some freak of nature P5.
Edit: and just to toss something else out there for everyone to think about, our intakes were at diffrent angles. Mine was more level, while his was angled way down. Again doubt it would make much a diffrence but something to think about.
