Default Just got a Dyno

Rocket Rally (the company I worked for) has just aquired a Dyno Dynamics AWD Dyno. We just set it up and are testing and getting comfortable with the new equipment. I just had my car on there for it's first ever dyno run. Engine wise all I have is a Ganzflow style intake and no cats with 2.5" piping. Any guesses on what it made? (We are at Sea Level and these are uncorrected numbers....60 degrees farenheit.)

I made 114whp on a Dyno Dynamics with the full MRT exhaust and stock intake. Stock was ~103whp (100-106whp range of 3 runs on 2 different days). So, I'd say somewhere around what Wiscon_Mark guessed.

Good guesses. I pulled a 109.7. My exhaust is currently GHETTO but don't want to replace it as I am hoping for an engine swap this winter. My intake I didn't expect much on. Also my car has 63,000miles (just over 100,000kms) so engine could be a little tired. After seeing some base pulls on Sti's and WRX's I was guesstimating 105-115. So pretty well right in the middle.
I will keep y'all updated on any modifications that may come to my car (if by chance I decide to go the TWE N/A route which is very tempting).
The dyno itself is great, very user friendly, very accurate and very real numbers...works great, looks good etc etc. Can't say enough about the Dyno Dynamics units. For anyone who may be in the general vicinity we are located about 45 minutes out of Vancouver, Canada. Dyno pricing/info is on our website: www.rocketrally.com
I'll post a graph when I can.

dyno dynamics is definitely a nice unit we(PDXTuning) are looking at those for our own shop, they are top of the line for sure

congrats on the new tool.

Dyno dynamics are load bearing dyno's. For more info click this: http://www.dyno.com.au/usa/specs/specs_450_LB_imp.htm

HFI Devil...that explains it.

Come on Tora give the guy a break. Up here in CO we have to take what we can get. I am not to excited to know for sure my car is under 100 HP at 5280 above sea level. But I expected it. So what is that as far as percentage of drive train loss

<--- sucks at math.

Give him a break on what? He wasn't busting his balls, he's just pointing out a known fact - Dynojets (and other inertia type dynos) read out higher numbers than Dyno Dynamics (and other load-bearing type dynos).

Thanks Pat..
I wasn't trying to bust balls...just explains why a mile high car would read the same numbers as my car. (BTW I didn't expect anything over stock on my car as it has a fair bit of mileage and no real performance mods to speak of at this point in time).

[ninja edit] Interestingly, if you apply this same equation to my dyno’d 256hp to the wheels, it means I’m putting out 391 ponies to the crank

No, it was a DynoPack unit, which I believe is the highest reading of all; and happens to be what TurboXS uses for the dyno portion of their tuning service. That said, they don’t use it specifically as a means of rating max power, but more as one of the many tools in the tuning process.

When I get tuned again in the couple weeks to support my new turbo setup, it will be on this dyno again. If I can make the schedule, another local shop has a dyno day towards the end of this month on their Mustang Dyno. It would be great to have the two sets of numbers based on the same new setup to compare…

Sorry Pat/Tora missed a in there. I was sarcastically saying let us highlanders dream of 100 at the wheels. But as you have said in the past dyno numbers are what they are, different types give different numbers. Not bad or good just what it is.

That would be ideal. You'd be subject to differing ambient temps, but so long as your setup is solid, then that would be great.
