740rwhp 93 octane TRX write up

Dino isn’t all knowing.

Sport the aux pump runs at 36%, as in auto, tow, every mode except Baja. In Baja it’s 64%.

It works without a tune, just works much better with the aux pump at 100%.

The shop I brought my truck too didn’t build my truck, didn’t tune it, nothing. I brought it there because I wanted to try a hub dyno since my friends at the shop Houston (built the winning TX2K23 gtr) use for their cars. I took my truck with 0 expectations, the tuner, hammerbuilt, no one set any expectations. This is a mild tune, it wasn’t designed to be misleading or otherwise. I expected 650-700whp. As I said, I made 627 with no tune and no chiller on a dyno jet (rwd).

Think of it whatever you want, just buy a chiller and try it out. Someone should easily be able to verify the claims with similar mods.

You’re absolutely right that I don’t know everything (my wife reminds me of that regularly)… just a lot more about this topic after two decades of building, tuning and racing than you. (I won’t even bring my education or career into this)

My IC pump setting in sport is 100% duty cycle. I’ll have to check the stock tune file map when I get home to see if that is a variable we changed last year…too many cars and can’t track all the tunes. Could very well be 36% duty cycle stock…would not surprise me given it is a suction pump. A higher flow rate also does not always equate to better cooling… there is a balance between rate of fluid exchange and rate of heat exchange which is why the stock system is programmed accordingly. You are also running an expansion tank which changes that calculation and usually hurts dyno performance but helps in the 1/4 mile when sized around 2-3 gallons (again it’s a flow rate and exchange calculation).

I would hope by now that you realize from every single persons comments on here (not just me in the least) that no one believes your results are real and that dynos are inevitably inaccurate. If I get time over the thanksgiving holiday I’ll throw my FI Interchiller on (if not it will have to wait until mid December) and take some actual accurate dragy data with the chiller on and off. Why don’t you do the same and then we can actually compare apples to apples? The only way comparing dyno numbers works is if we meet up at the same shop the same day and do our pulls…which if I’m doing that much effort I rather just race for some $. I’m still very open to a $10k race.

PS- your use of emojis concerns me. I expect that crap from a narcissistic Gen z brat with no life experience that thinks whatever his opinion is is valid because he can Google something online to justify himself. Hoping that description doesn’t fit you. Of course I also expect Gen z to believe in unicorns and magic which is basically your suggestion for your truck.

Agreed. He's also using the term "Mickey Mouse" wrong. 🙄

I agree with you on the high flow rate .
Moving to fast can actually cause worse heat transfer .
I see this in hvac a lot and usually have to slow the pumps down and allow for proper heat transfer .
just another nail for those dyno numbers being a scam .
 
I wish RAM would offer the “Power Brokers” tune like Dodge does on their Hellcat platforms. I just want a little more power without voiding my warranty. 🤷🏼‍♂️
 
It’s not impossible, I’ve proven it. Prove me wrong. Set up a truck same way, similar tune, and dyno it. No one has ever done it. Until someone else has done it, and doesn’t have similar results, it’s all white noise.

Prove the haters wrong and put some times up! Plus it’d be nice for you to know how quick your truck truly is.
