Went on the Dyno today

[LOL WUT]

I'm not sure why people put so much value in dynos given the vast variance between each specific dyno and the environmental conditions. I will never understand why people get disappointed or excited over dyno numbers or when people state "you should be at blah blah blah HP." The track is your proving grounds unless of course you want to run around saying you have 470whp when really it was just a generous dyno and you're at low 400s.

i would imagine it being outside under a tent in 98 degrees with 2000% humidity after it rained earlier than morning didn't help any of it... you prob would have gotten better numbers on friday or thursday during the competition.

SMH, I don't understand why people keep talking about the track on dyno threads. If you wanna see the impact a specific engine related mod has on the engine, then the dyno is the only real way to measure that. The track shows you what the car itself can do. Neither of them are the end all say all. You can see how certain engine mods affect the entire car at the track. But that doesn't make it more accurate or a better test. Just because something is popular to say or is the trend doesn't necessarily make it true.

My issue is people who don't have a baseline going to some random dyno and being upset about their numbers. It just doesn't make sense to me. Your opinion is valid if you have a baseline and go back to the same dyno when additional mods are added.

From the reading I have done, the 350 Im dyno'd cars are showing a significant drop in torque. Most people say the cars feel more stout on the butt dyno though. Track times will be interesting. Could be that where the engine is seeing torque losses is at a point where there is an abundance of torque and it's a non issue.

I think it's fair to say that MOST Mustang owners don't take their cars to the track for various reasons. The dyno ends up being the only way to verify the performance gains for the money you put into a car. Regardless of getting a baseline, it's the only way besides the track to get data on what the car is making. It's a shame that there is such a variance on the dynos themselves, not including any environmental factors.

One guy on the board here just by adding a gt350 IM gained 3mph and .3 in the quarter. Went from 116 to 119.

I agree about if you don't get baseline numbers. However that is time consuming and costly. Typically, dyno is 3 runs for $100. Now if you add 3 baseline runs, that is $200. And most shops won't have time for you to bring a car in, dyno it, then put the mod on, and dyno it again. Most people won't have the time or desire to do that either. Same with the track tho, most people don't have the skill, time, or aren't close enough to a track to go there again and again. My track is 45 minutes away and that is close compared to some. But that drive sometimes just takes forever. ANd then if conditions are different or if you're not up to your best that particular day then your times won't always reflect what the mod did. If you want engine results, then the dyno is more reliable than the track. If you want to see results on the entire car, then that is the track's duty. BTW, I wasn't picking at anyone in particular with my comment. I just get a little agitated when people compare the dyno to the track or comment that the track is the only way to gauge results.

This car ran on the same dyno..

Its most likely the weather, da and humidity your tune might not be done being fine tweaked yet. Obviously being auto is going to kill peak numbers. Generally takes a 3-5 via email to get dialed in. Has lund said its done as far as revisions? Have you expressed you wanted a tune on the aggressive side?

 

[RockStang]

They didn't specifically say they were done. All i get is, logs look good, have fun. I did not tell them I wanted an aggressive tune either. This goes along with the poor communication that I've posted in other threads. They are the experts and should be giving me information and asking questions to make sure I am good with how the car is running, telling me if there is more left in the tune etc. Some general guidance on how it all works would be very helpful from them. Anyway, we'll see how it goes this Friday. If the car runs poorly, that's on the tuner.

i gained 1mph and lost .1 in the quarter with 3.15 gears.

That's all in the tune. I only lost 8.8 tq but gained tq at the top. Also gained a huge amount of power up top.

Without baselines, perfect weather condition, etc, you can never compare yours to someone else who you saw with the same modes. They are literally tools used to compare tuning & parts. To measure the gains in between the differences of the car. I'd say looking at your chart, your car pulls amazing. The power/torque lines are so smooth looking and stay strong all the way through.

I'm not really comparing ours I was just showing the other poster that the supposed large tq loss is a myth. Yea My car pull like crazy lol. My chart is showing a before and after gt350 intake and tb on 93. I already had full exhaust and jlt.

If you didn't dyno your car on Dan's dyno when your car was bone stock in similar conditions, then you can't use these numbers as a reason to be upset. Dyno's are a tuning tool to show the delta between changes made to a vehicle. Unless there was another car with your exact set up that dyno'd around the same time as you and made 430+ rwhp, there's no reason to be upset.
