Brainstormin' 440 vs 5.9 ...

Well, didn’t you hit nitrous to get that mile per hour?? And did you hit the nitrous on the Dino?
Yes. The nitrous was on. And yes I have chassis dyno data with nitrous. It was activated very late in the run on that pass and I would say had little influence because my controller was not working how it should have been. Also, as slowly as I had to roll in to the throttle in first gear, to save the 8-1/4 peg leg diff I’d say it’s a wash. It’s all bench racing anyway really.

Nitrous chassis dyno hit.

Answer ??? Anyone ???
So the Dyno says gross hp of 500 hp and Wallace says gross hp of 375, obviously Wallace is wrong. If you took his engine out and ran it on any reasonable dyno as is no way it will only dyno around 375 hp.

Let's say the Wallace is generally in the ballpark there must be circumstance where it ain't, Just mph and peak power to weight can't cover all bases and be more accurate than measuring the actual torque @ rpm physically from the engine.

Either Joe is so bad at tuning his engine and it only makes 375 hp now or Wallace can be wrong. I forget who said it but it seems to me Wallace tells you more like the minimum needed power than the actual.

I disagree with everything in this post. Merry Christmas my friend !!
 

So, I take a known 2000hp no prep car out, cant hook and run a 12.30. What would Wallace say i have for HP in a 2500lb tube chassis car?

When calculating horsepower, I don’t care about ET. I care about the MPH. MPH shows the horsepower. ET just shows how well the car hooked, how right the converter is, the gears and how hard the car 60 foot. Prime example is stock eliminator. They often run a much better ET than the MPH would indicate.

Ok, I think you get what I am saying. Should have said some random MPH
instead. Either way, based on chassis, driver, or whatever, it will calculate it wrong.

I think we were pretty clear in previous posts and in my video that if you go extreme in something, such as tractor gears, the mile per hour isn’t going to reflect the horsepower. The same would be as if somebody spun their tire one legging it to the thousand foot mark. Kind of like if we use the extreme example of pulling 3 spark plugs out of the engine on the dyno and then trying it. kind of just fruitless.
 
There is basically no reasonable situation where Joe's 500 hp truck engine only dyno's 375 hp like Wallace calculates, it may dyno like 450-500 hp on other dyno's but without extremely handicapping it, the Wallace prediction is obviously wrong, is the truck severely underperforming sure, why ? Idk but obviously there situations the Wallace calculator can't compensate for.
 
Obviously Joe's truck has more than 375 hp (gross crank dyno trim hp) and if it can't mph what you'd expect a 450-500 hp would do for a given weight (his truck) there must be situations where a vehicle comes up majorly short in mph on the track. Obviously the answer isn't if it comes up short the dyno lied, obviously something stopping it (not hp) to mph better. What is it ? IDK. But he didn't lose a 125 gross crank hp from the dyno to his truck.

How much horsepower did he lose? And what is wrong with the truck??? Wallace says I have 344 horse. But my truck is heavier than Joe’s. So maybe Wallace is wrong on mine and I really have 470 hp. My argument is more solid than yours above. Because Joe and I are racing identical trucks, except his is lighter than mine, a short bed. We almost have identical gearing, same transmission, he would have a little better torque converter than I, cutting the same wind, so I could argue that mine has 470 hp by your reasoning and be more correct. So let me write the book right now for the cheapest, simplest, 470 hp 360 on earth.

Does Wallace account for transmission type, traction, duration of optimum torque during the pass based on stall and shift points?

Perhaps, Wallace should list a “percentage of accuracy.”

Duration of optimal torque, and shift points?? Yes! Wallace accounts for how much fuel is in your tank, and where the tank is located, if you even had pepperoni on your pizza!
 
OK guys, I’ve seen the measures of people will go and it is beyond reason. We have 2000 hp tube chassis cars running slower than my duster, and now we have Wallace measuring shift points and garden tractors doing 5 mph. It’s been fun and we’ve had our sarcasm, but I just gotta move on. No disrespect to anyone, but I’m concluding my posts about Dyno and Wallace. Thank you all! I will move on to where we left off, and that is the RV 440 and my truck. Thank you again.
