Dyno run

[Jwithing]

My buddies RS focus numbers. He is disappointed. We are thinking he has some kinks to work out of his tune. Looks like stock numbers and Dyno guy was even saying the high rpm was dropping off way more than it should.

Feel Free to Hook me up with some Kicker gear.

I was Kicker Competition Group 1999 and USAC SQ and SPL dual world finalist in my 1998 RAM SS/T

Then we may have met, Greg Davis was your guy...but I traveled with Gary Biggs, Mark Eldridge and all the team mid 90's until the end.

valve float? Not a big enough turbo, etc...

also he didnt get one of the Hand Grenade RS engines that mistakenly has the Mustank Ecoboost Head Gasket.

I bet we did meet. But yeah those were the big guns in the Pro class. I was Novice/amateur

He got home and read his data logging and he said the timing went negative. It was the first tune, he still needs revisions and wanted to use the data logging from the Dyno for his revisions vs. running it on the street. It's a 2018 RS, he said they fixed the gasket issues in the 2016 or 2017.

Sorry to leave you guys hanging! Had to run home 40 minutes to grab my hellwig sway bar that just got delivered and drive another 40 minutes to drop it off at the powder coaters before they closed.

Here it is. Didn't get to run as many pulls as I wanted so I didn't get to try the clutch fan on or stock tune. 1st pull was in 4th and 2nd pull was in 5th. He couldn't get any to read after that. He said something about the Dyno learning the vehicle and being finicky when it shifts so it can't be 'cheated'. Idk enoguh about dynos to know if that's true or if they wanted to get the hell out of there on a Friday afternoon. They only charged us at the rate for 3 pulls. Vs. an hour each. I told him that my 1:1 gear was 6th since that's what I read on wiki, but he couldn't get them to read and those runs sounds ded like ****. He said he believed the closet 1:1 gear would be 5th. Maybe someone with more Dyno experience on here could should some insight. I'll post videos in a bit.

 

[Jwithing]

The guy running the Dyno said he was extremely impressed and asked who tuned it. He said the tuner did one hell of a job

 

[Jwithing]

Here's a link of the videos. The videos don't do the sound justice. I didn't realize how loud my exhaust was on WOT. You could feel it in your chest lol.

NICE! More than I was expecting. Is that a corrected graph or did it actually throw those numbers down on those huge tires?

No correction. That's with the big meaty bad boys lol

I guess I'm more optimistic than others--I think your going to be around 360-375. I still think that the 1/4 is going to be where your truck really shines!!!!!

Good job man!!!!! I had faith in you----LOL

[hoe...]

I was excited to see that the first run hit right at 355 like I guessed and was even happier with the next pull lol. The guy had me doubting my guestimate.

The correction is STD with a smoothing of 5.

So the 387 run is 5th gear? The truck down shifted in your video at around 16 seconds which is why the TQ jumped so high.

Either way its nice to see what a truck with 37's will do with just simple bolt ons

Here it is.

Nice!

Most dyno operators use 1:1 because it removes the tranny gearing from the calculations. Usually not a huge difference doing pulls in a lower gear, but will usually show higher numbers. However weather variations can have a big affect regardless of ratio. As can heat soak. Hell, the numbers will usually change from pull to pull due to the later. Dynos are cool for two things. (1) Bragging rights. (2) Tuning and comparing component swaps. But neither directly translates to track times. The dyno is an artificial environment. But it's still cool to have some numbers. Most operators also use SAE correction so numbers are comparable to pulls done in different locations. Altitude, for example, makes a huge difference.

For those without a dyno handy, and/or that've been to the track. You can get a somewhat representative number from your weight and 1/4 mile trap speed. Many drag racers rely on this calculation alone, but it's ballpark. There are plenty of calculators for this on the web. Or you can use mine if you like.
