How did you calculate that? We both drag at the same track. I am doing 7.2s while he doing 7.0s at the 1/8 mile.....big difference. You are obviously calculating your research on paper and coming to your own conclusions. Not trying to be funny, but the increase power from this car is not rocket scientist.
Your point was mistaken. You said lower to mid powerband.
The car is not at lower power band during wot runs. It is upper middle to redline the entire time.
If you want to feel peppier passing power while lugging the engine at 2000rpm, you go for low end gains. If you want the car to get somewhere faster your want top end gains.
I gave a specific rpm range of 2,000 to 5,000 rpm range I don't see how that could be any clearer to you. Horse power increases at and below 5,000 rpm's will show up on a time slip. 0-27, 35-45, 58-64 and 84-89mph are all happening at under 5,000rpm. That's 48mph total of a 0 to 89mph acceleration run. That's why most if not all of the et reduction are seen in the 1/8 mile.
If your so convinced that a few simple bolt ons make no difference I'd be more than happy to prove it to you at Bradenton drag strip. My only modes are ported intake, TB, Halltech and a drag pack, so put a drag pack on a stock C8 and prove me wrong.

You said 2000rpm to 5000rpm
Now you're saying 0-27mph???
You're running a 3500rpm launch. You're starting at 3500rpm.
Once people unlock LC those with slicks will start even higher.
None of those speeds you listed are under 4500rpm.
That's where are mid band ends. Divide 6500rpm by 2. 3750 is our mid rpm band. You'll literally never be there much less lower rpm band that you also stated.
Again. Trap speed is power. E.t. is a multitude of factors.
I'm not "convinced" of anything.
I literally listed the variables that indicate power and gave the objective data back. I'm. Not sure what you're arguing with.
If you think an intake gave an additional.4 seconds in the 60 foot ok but I disagree as would anyone who has tuned a car
We get it, but it seems like you don't get it. We have already said that horsepower sort of flattens out at the end as stock with simple bolt-ons. I have beaten many cars with more top end than my car. So they must have more horsepower at the top end.....is that what you are trying to convey here? Because that horsepower at the top end didn't do them any good for them.....nothing at the bottom end. We are not racing a mile for the more horsepower car up top car to play catch up. If running 1/2 mile of course horsepower will come into play.
Put your draggy calculations on the side and show us some track numbers for comparison.
NonZ51Mark C8 was an eye opener for me. You got to pay to play.

If you're purchasing bolts that "flatten out" at the mid to top end than anyone would ask why you're buying them. Again, under wot you are literally always above 4500rpm.
There are certainly bolt ons that makes a bit of power up top. There are also timing changrs you can take advantage of up top from e30 which all the fastest people are running.
I am making no comments about generalized parts.
I commented on the persons data who literally asked for advice on interpreting it.
I did that for them. If you're only looking at e.t
That's a terrible way to interpret
It should not come off that I am in any way giving my opinion on any parts I'm just interpreting data.

Look at the graph, 0-27mph are at and under 5,000rpm. When you shift into 2nd at 35mph your rpm's drop to 4,000. Look at the graph and the rpm drop after each shift, that's where my numbers are coming from.. Why do you keep bring up 4,500rpm? Forget I said mid to lower rpm range and look at everything at 5,000 rpm or less which is below peak horse power rpm. If you make more hp at 5,000 rpm or less and the same hp at 5,000 and above with mods your car WILL BE QUICKER! Mods don't have to make more peak hp to realize improvements in your et's. A car with a flatter hp curve will accelerate faster if all other variables are equal. Why are you so unwilling to acknowledge this? Are you trying to convince people not to get mods so your car will be faster with them?
Plan and simple......bolt-ons is a starting point.
NonZ51Mark just illustrated the reason why the car won't pull top end even with superchsuperchargers. Something you may have missed which was discussed in another topic.

You are at 20 mph immediately upon a 3500rpm launch
Low end from 2000rpm to 4500rpm is simply not relevant on a 1/8 mile run nor a 5 mile run.

Absolutely. The right ones. I enjoy testing them. Some do little to nothing. Some do more. To objectively determine what they do you use CONTROLLED condition acceleration testing and datalogging. E.t. and dynos will be way too confounded by other variables.
I'm with you are gearing limits in 5 -8 but you still can see 129mph trap speeds with just bolt ons in perfect air on e30.
Regardless we were only talking about comparing two runs of the original poster.
That's all I did was helped to compare the two runs. Those focusing on e.t. were simply wrong when it comes to relating it to power differences.
I showed you all how to do it if you want to.... which is what the op asked for.
The guy in the video stated that the car picked up half mile or mile with bolt-ons. That's about right. So why did he removed them? Again he's not on the track. Doesn't prove anything to me......just another draggy episode on the highway.
Since you live in Florida, why dont you just meet us at Bradenton Motorsport Florida later this fall. That way you could prove your point.

Lol, yeah he's one of those guys that would rather run 11.20 at 124mph with a 60ft of 1.60 than 10.80 at 123mph with a 60ft of 1.60 and loose every race at the track but tell everyone his car makes more power. I prefer to post a low et, I like posting a faster mph but without a good et it doesn't win races.
He continues to use 4500rpm to try to fit his narrative, simply refuses to use the stated figures.
The more the merrier! Usually there's 4 of us or so, would be great to have a large group so we can compare notes and see what everyone is running at a track the same night.

It doesn't make any sense at all to remove mods that gave you an improvement. It does make sense to say you removed mods that you can't tell without removing them, like an intake, throttle body or airbox that you can't see. That way you can have an advantage over someone who doesn't have them.

Exactly......there was no point of mentioning the mods in the first place. So I would say he never had mods. Just another youtube click I guess.
Next time the temperature gets down to 60 or lower and the da is near zero or negative on a Thursday night I'll be going and post a new thread and here to get the word out. Some weekends might also be available depending on what kind of event might be happening. Anyone else feel free to do the same, it's always a great time!

?
Why the hostility over me trying to help someone understand data? So bizarre people get "he's one of those guys" because I show you what trap speeds are versus e.t. that were all gained in the first 60 feet.
Yes let's say if you run a 1.5x 60 foot and an 11.2 at 122mph versus a car that runs a 1.8 60 foot and 11.5 at 124mph that car is making more power.
Is anyone honestly disputing that???
Yes and Bradenton is not South Florida lol as I've heard it referred to as.
I'll be up there at some point. No worries. I get around Florida. This is really not a competition lol. No idea why you are making it that.
Never said anything about anyone's car or their mods. Literally just interpreting data. For all I know your car heat soaked longer on the day with the halltech and had a 15 degree higher starting IAT. If folks understood that could have caused the power difference then maybe youd be less defensive lol.
......
As for my car, you can very easily see what throttle body I have on my car. They're not hidden. You can also see if the ptr is on there. You can also see the stock or modified exhaust.
I have literally just put on an AFE intake for testing this month. I put it on with all else stock so I am testing one part.
Just got done with same day stock intake versus afe intake controlled condition logging controlling for
1. starting iat.
2. Wind direction and speed
3. Tire pressure.
4. Ambient conditions
5. Direction of travel / slope
6. Fuel quality
7. Weight in car.
I did collection of
rpm
air intake volume
Timing
Knk
Stft
Iat
ECT
These are the logging variables i do when testing intakes, throttle bodies or manifolds.
I may very well remove it. Do I want to sacrifice filtering versus 3hp? I'm not sure yet. I did before hand oil testing for silicates and will do an after test too.
I have now put on a Borla S catback literally yesterday.
I'll do some testing on that but I am not expecting more than 5hp. Whatever.
Do I think my car is now going to go 125mph in perfect air with a catback and afe intake? Probably not. Maybe though. That would be 10hp or so. No idea until I check.
The car will go an additional 1.5mph with e30 though. I haven't performance acceleration tested it yet but logged it and see an additional 3 degrees of timing.
