So you're telling me you went from 347hp/315tq N/A to 481hp/520tq (per dyno video) with just a 100 shot?

How much difference you think you're getting from the 420s to 555r?

Predator 5.0

347HP/315TQ was on 91 Octane and 20" FX Appearance Package wheels and 420S tires

On E85 and 18" FX wheels and 555R drag radials, here is the dyno sheet of my truck on the nitrous tune, all motor and on spray.

Gained roughly 120HP/190TQ from a 100 shot.

Wow, that is insane! you have approx. 200 less rwhp than us and your time is faster, 481rwhp, crazy. Am I missing something?

Fordjunkync

Predator 5.0 truck is more efficient than those with more HP with slower ETs.
The "LIST" is competing in the 1320ft & not the Baja/cross country races or etc (not to be sarcastic but its meant as engine build specific)

Torque=Work
HP=Work over time.
Time=RPMs

Increasing horsepower doesnt always increase torque to where its most useful.
(Theres more but thats the gest of it)

Note: Research into how engines are built for the EngineMasters challenges.

If the ecoboost had 200 more rear wheel HP than this truck they would be at almost 700RWHP...

Damn, Spraying at 2500rpm Ballzie, must be a great tune.

You're missing two things.

1. He's not faster, not really even close. He did a 13.2@106 vs say my 11.72@117 while on the dyno I made 540hp (I'm guessing it's more like 570ish on the same dyno now). The MPH tells the story of HP. These engine have always been known to make more HP on NO2 than the pill is set to and I think the altitude is providing more of a difference too (correct me if I'm wrong).

2. Dynos LIE. I've said this before and I'm saying it again. The dyno is just a TOOL to measure gains and losses (and other parameters can be added). As can be seen with the NO2 he make very nice gains but in the end the HP/TQ make on the dyno doesn't matter.

Who is "making more HP" but has a slower ET(other than youngerone but his 60' tells the story there)?

True on it doesn't always help (if the lose in low end torque to make the high end torque hurts 60' times) but once you're out of the hole more HP=more torque up top which is useful.

I wasn't pin-pointing anyone & making it personal.

I was just referencing to the post below in a general fashion.




Reducing the 60ft #s multiplys the reduction of ET down track.


Thats a give-in & is standard knowledge.

Didn't think I had to list torqe and 60' also. I guess this is your first time here to this site cause we are all familiar with each other. I have a lot more torqe and my 60' is better. Just amazed by the lower hp and torqe at 11.51 to my 11.74. Must be the altitude! Thanks Ford Junkync for trying to explain what everyone already knows, lol. And just so you know, many of times I've had the better 60' and lost the race. And do you know why? Yes, cause he had more hp and tracked me down. Don't knock the hp, Go Baja!
