We are going to be trying to get a few sets of intakes made over the weekend for sale. I have been getting a ton of messages and phone calls asking for some. We are just so swamped it is a little difficult to get to everything.
We are just posting a video of how the car is reacting to all the mods we have put onto the vehicle. So technically we increased the power to get to where we are.
Something that everyone should keep in mind when looking at dyno numbers is Dynojets will read artificially high. Mustang dynos are more accurate, seeing between 15 and 20% driveline loss.
STD corrections will usually be higher than the more widely accepted SAE numbers.
A Dynojet using STD corrections will see almost no driveline loss (probably less than 5%), leading some to believe their car is an absolute factory freak. The same car on a Mustang or *gasp* Dynapack dyno with SAE correction will read a whopping (more accurate) 10% less.
***Disclaimer: The above information was gained by doing research back in 2011ish, back in my Corvette days, and regurgitated from the memory of a 35 yr old man (me). Things could be drastically different now.
The relative accuracy of a dyno's not as important as being able to witness the gains (if any) of modifications on the SAME dyno. Sure, temperature and other conditions that change day-to-day are an issue. I'm looking for gains under the curve of modifications tested on the same dyno as other modifications and/or even the stock setup. From there I can see a percentage change, which is more applicable as we move from dyno setup to dyno setup.
Every dyno from every manufacturer will put out different results. When you're looking at small differences, everything from ambient temperature to heat buildup within the machine will make more of a difference.
As Kazz stated, they are excellent for comparing results before/after changes, but absolute numbers are not to be taken as gospel.
This really isnt the place to debate which dyno is better we could go back and forth all day. According to our results and calculations our car addds up correctly for the power we state it has. Xcceleration
