But that's without Jan's tune, right?

Correct..."tuneless"...

 

Here's the dyno showing 225.9 ft/lbs of peak torque:



...and the dyno showing 213.8 peak HP:



Kind of interesting that the peak torque dyno also had the lowest HP reading (202.8 HP) of all the pulls done (and this one was the first). Again, this is post-mods and pre-tune, so there should be s'more HP and torque coming. Stay tuned...pun intended!

 

a DynoMite dyno eh, I wonder how that compares with more common dynos ?
I'm sure the tune will make a huge difference, but I'd like to see it done on a dynapack.

 

I agree with orangecrush, you should definitely get an IC.

Forge or helix.

Also, apparently RMW tunes on JCWs don't yield massive dyno gains, but you can tell from orangecrush's posts that the difference is massive

 

he does have a Helix IC.

 

Correct! Thank you...all (engine) mods are listed in post #1...I didn't want to keep repeating them...

 

Here's the 411 on the dyno: http://www.ondemandperformance.com/equipment.php
It's not a DynoMite (that's the data acquisition computer) it's a Land and Sea chassis dynamometer.

They read more "realistic" like a Mustang dyno as opposed to some of the more "optimistic" dynos out there, like a Dynojet. No matter, that's why I use the same dyno for ALL of our vehicles; I don't care what it runs anywhere else, I want a consistent baseline so I know what I'm getting...or not getting from the mods...

 

do you have a single dyno run with both those output numbers and an overlay with your baseline runs ? I'm seeing 1 run w/ your best torque and another run with your best peak hp and no baselines.
Not trying to give you a hard time, but it's hard to gauge.

 

Not at all...I'd like to see that too...I'll ask the dyno operator to do that fer me and I'll post it up. It's definitely nice to see the improvement (or lack thereof) throughout the curve, not just peak. He just printed these up and we took off; I definitely don't like keep someone late when they're doing me a favor, especially on a Friday night! It didn't help that one of the straps got boogered up either and had to be cut off with a torch...d'oh!

 

my bad
