now i have been thru many, many threads that have had different WHP numbers on different dynos and a couple questions come up...

see i know what i have, but i'm tryn to compare my power @ 8.5 psi to other set ups on the same psi

whats the difference between the dynos...
do some read higher than others?
if so, how can you determin a standard playing ground besides putting every car on the same dyno

and i'm not tryn to call out anyone, so don't get defensive. i'm just wondering so i have a more solid understanding whats out there and what are TRUE numbers

 

Dyno's reading highest to lowest:
-Dynapack
-Dynojet
-Mustang dyno

Mustang dyno's are generally regarded as being the most accurate.

 

where would the dyno dynamics dyno fit into place?

 

it doesnt matter what dyno ur on any can read higher or lower depending on if they have corrections on or not etc.

 

First thing you should know is that you should NOT compare your dyno to someone else's unless you were both dynoing at the same facility.

A dyno result should be for you. Use it to compare future dyno plots to see gains/losses from mods or whatever. You should use the same dyno facility to get the best comparable data - you should also dyno in the same weather conditions.

Comparing dyno plots to others is almost pointless.. too many variables are at play to get a fair comparison.

^ Same

Totally the case. For example you could take your car & current set up TODAY to 5 different dyno's in your local area and you'd get 5 different numbers.

Dyno's are a tuning devise not a precision machine.

 

Ok. I understand they all aren't gonna be the same. But what are we talking?, a few hp differance or 25-40 whp differance.
Ok rob take for example your new kit puts out 320+whp on a dyna pack. If that same car ran on a dyno dynamics or a mustang dyno would is still be on that 315-320 whp area. Just using that as an example since it's fresh on my mind.

 

Mustangs show lower.. how much lower? It depends.. it's not an exact science.

What's even more absurd is how someone will dyno on a Mustang dyno, get XXXwhp and claim that it's X% higher on a dynojet without even testing it on a dynojet.

 

Over the years I've seen about a 5% difference between unit to unit.

FYI...Just want everyone to know the dyno #'s of 275WHP we posted last year on the first version of the DESCENDANT kit with the Bullseye Power Turbos were at the same dyno (Shawn Church Automotive) I just posted the new Ver2.0 Precision Turbo #'s from.

 

Ding Ding Ding! We have winners.

 

thats what i wanna know.. there isn't a science to it.. ok

i didn't know if they all where set up the same way. but from what i understand they can be tweaked hi or low...

but ok if you have it tweaked to were it reads high won't that just come around and bite you later when the car has to preform

 

If you want to figure out how much power you have compared to other kits, prepare to do a lot of math. A dyno will not tell you anything.

The only thing a dyno will tell you, is how much of a change occurred when you changed X value to Y.

 

like i said.. just wondering if you can have a more accurate way for reading or know whp, but i i guess its pointless..
i guess i'll just find a couple different kits on the same psi and take it to the track...
sorry for the pointless thread

 

The only way to compare different kits is to either, A. Arrange a dyno day, where all the cars with different kits would run on the same dyno, during the same climate conditions, or B. Buy all the kits available and install them/run them on the dyno, one after the other.

Or, you could do the math, which will tell you the real amount of power you're making, not the dyno fluff numbers.

 

Dyno day with all the cars is good.. but we know it's still not completely free of variables. Not all cars are made the same - or have the same wheel diameter either.

Why the emphasis on the exact number between the kits? For people who want to shop for a turbo kit, they should realize most of these kits will make roughly the same power at a given PSI on a stock motor.

Shoppers need to look into the following:

Build quality
Engine management supplied
Company's customer service
Flexibility to upgrade
Emissions (some states)
Ease of install (some require more effort than others)

 

This is exactly what I try to explain to people - I have a dyno software with my obd scanner - yea the dyno numbers dont match up well with any other dyno out there, but that doesnt make it worthless, it gives me something to use to judge increase vs loss when tuning my car which is all a dyno is really supposed to be for. If you want to prove you have more power / are faster than someone do it at the track. Racing on paper is ftl

 

A dyno day is still closer to comparing two kits than comparing two different dynos, with two different altitudes, and two different temperatures...etc. At least with the dyno day, you're elimiting all the variables and narrowing it down to the mechanical aspect.

 

Redundant thread, not pointless.


This is a pointless thread.
