Does anyone have a JR SC installed?

Same can be said the other way to make themselves look like they know how to make power. thats just my opinion

just to inform people who do not know, mustang has a library of cars in each system that automatically enters in factory weight, gearing etc etc of each vehicle. not sure what others do but we use the factory recommendations for each car. we do not enter "guesstimated" information like I have seen some dyno operators do. not sure if dynojet is this way too.

But from past experience with personal vehicles, dynojets always read higher when going to different dyno days.

@ramiram1984 was pushing 280 with full exhaust and headers with a custom tune.

And if I can show 2 cars with a 3 - 4 % variance on my dyno compared to the same 2 cars on 2 different Mustangs, (a calibrated 18 year old Mustang and an almost new Mustang in a different state,) I would think that I'm pretty close, at least in the 400+WHP range... But that's just me.

Modified did a "dyno dash" here in WA some years back, and while the Mustang did read lower, it was also preloaded @17% for some odd reason, instead of being an inertia based run like the rest.

FWIW, & cheers!

the difference at those numbers (20whp according to that article) will be amplified as you rise in power. We had a evo 9 that dyno'd 502 whp here that had made over 6xx at EFI's dyno in Connecticut. The difference showed in that article is still significant. Idk when a 20whp at 292-312 wasnt.

A dynojet reads higher then a factory setup mustang dyno or dynodyamics.
Compared to a dynojet 248/224 AWD about 14%, compared to a 424 AWD around 16-18%.
The dynodynamics being the lowest.

Unfortunately all can be altered, especially those DJs at elevation where a simple shift in correction factor settings can pick up 100+whp

None of that shit matters anyway, if you have to try and convince your customers their car is good you failed anyway.

No matter what, at the end of the day all that will matter is the real world performance. You mess with numbers, you are only hurting yourself in the long run when your customers start to figure it out.

That is all true and as long as you get your Dynojet run files from the dyno operator, then you can open them up in Winpep and easily see what SAE correction factors were entered into the file including elevation and temp.

Or they change the drum info, and your now making another 10-20% over a normal properly sized DJ. Few ways of doing shady shit with a dynojet..

That certainly wasn't the case in the said article.

But it's true about fudging numbers - just had a BRZ come in between these posts on my Dynojet with 40WHP / 25WTQ LESS than the Dyno Dynamics run he has on file, so I'm not sure if there's any validity with ANY of our opinions at this point.

I used to post SAE numbers here on the forum if your recall but when everyone went the way of STD, I just stuck with the expected "norm." Just like boost plots.

I suppose, but it's not like you can't skew ANY of the numbers on ANY other dynos either. And based on the principle numbers, we're well within the norm, both in the article as well as with our bone stock baseline FRSs.

Cheers!

How has it been? Any hiccups or all smooth?

I am not sure how this thread became about dynos...

No issues. Almost feels too good to be true some times.

That is my point, anyone can mess with the numbers to read both high and low. In your case some dbag jacked up his dynodynamics to read really high, or the other option could be dyno shops that uses tricks to make baselines read low to "prove a point" and look like a hero.

So at this point its up to the user to trust the shop/dyno to be honest with them. I dont know about you Mr. DriftOffice but I have been using AWD dynos since about 2000, or roughly 14yrs now and have seen it all.... So I can give my opinion, but back it up with lots of facts. Everyone always wants to be a hero, superstar.. but very few actually are.

So again, A unmolested dynodynamics will read the lowest, followed by a mustang dyno, then a dynojet.. Dynapack being the highest reading from my experience.. This is all based on the dyno being left un touched and in OEM delivered format.
