I also put wax on the valve covers and installed a chrome breather that's at least 15% more power.

So, Put the cougar on the dragstrip for that Mid to High 12 at best. It's not running high 11's as it is. Pipe Dream

Any online calculator uses RWHP not Flywheel when estimating 1/4 1/8 & ET

TimeWarp,
You might not be familiar with the WerbyFord Gonkulator (so named years ago not by me).
It was written by me over the past 40 years and is NOT an on-line "horsepower wheel".
At this point I'm inclined to repeat what Paulie said already:
"Sounds like you've got it all figured out".

I agree Paulie should weigh his car.
But it wont be more than +/-100 lb from what I have assumed.
You are wrong about the GTECH.

[Heo]

Werby, that gonkulator what exactly can it gonkulate?
obviusly from standing still to 1/4 mile times
And what data does it need to gonkulate what

Origin of the name "Gonkulator" from 19 Oct 2006 (wow time flies):
https://www.fordfe.com/brent-i-got-your-email-gonkulator-predicts-591hp-t48890.html

The original "horsepower wheel" (input car weight & 1/4 mile ET or MPH and it outputs NET horsepower) is a correlation by Roger Huntington dating way back to the 1960s. Its just a cubic relation scaled to fit the data of hundreds of cars.

Before TimeWarp deleted all his posts here (not sure why!!!) he stated that a "wheel" can only work in terms of REAR WHEEL power. Physically, that is correct- the car responds to what it sees at the rear wheels (well, at least for normal cars), not the flywheel. But the original Huntington correlation was an attempt to go directly to NET ENGINE power.

And it's not too bad - give or take about 4 mph which is like saying give or take 40hp, within the scatter of all the data on that correlation line.
I use it as a quick estimator (as do many here) but that's all it is- a sanity check.

One problem with many of those on-line "wheels" is they don't really tell you whether they are spitting out REAR WHEEL power or NET ENGINE power or some inference from one to the other.

The WerbyFord Gonkulator (similar to the commercial Desktop Dyno, Quarter Jr, Engine Analyzer, and others) starts right from specs for the engine- cubes, head type and flow, headers, carb, and spits out a curve of Torq at RPM and Power at RPM.

Then, it takes inputs like belts, ram air, car weight and aero, transmission, rear, etc, and spits out a "timeslip", 60ft to 1/4 mile, 0-60mph, top speed, etc.

The Gonkulator MOE (Mean Observed Error) is about 3% on Torq and Power. For the FE series its more like 2% (my favorite engine series or at least the one where I have the most data & experience). The MOE for 1/4 mile ET and MPH is about 2%. So it's not perfect, but better than the "wheels".

AND, to me, the best feature of the Gonkulator is, it will assess a CHANGE you want to make- ditching the mufflers, adding cold air, shift RPM, etc. Not perfect, again, but it does ok.

Here is the Gonkulator input list. I might have missed a few things. It also does NOSS-Spray-Nitrous in a cursory way since some of the kids are "into" that stuff today.


Engine
Air cleaner
Air source eg round open underhood, snorkeled [yuck], cold air shaker,
t-bolt via headlites, etc.
Fan / Power steering / AC / AIR / other belts / elec water pump
Carb type and cfm
spacer
intake type and specific model, that really matters
If "mystery" intake, pictures and measurements eg port sizes, "A" and "B" as
Edelbrock measures them, and distance from carb flange to bottom for each hole.
cyl head type, casting # eg c1ae-a, valve sizes, flow curve or even 28" flow at .500"
at a minimum (or else guess), port sizes if unusual.
Rocker type and Ratio
cam: mech or hyd, flat or roller, .050" duration, I&E lobe centers (eg 106i, 114e),
gross lift and lash if any
compression ratio
bore & stroke
rod length
deck clearance
head gasket thickness
pictures of combustion chamber and piston top if unusual or new design
exhaust manifolds or headers, primary diam, lengths [of each tube if known],
collector diam and length
exhaust pipe size, muffler type and size

Car:
Trans type eg c4 c6 top loader, converter stall, gear ratios
Rear, type eg 8" or 9" and ratio and Det Locker, etc.
Tire type and size
Car eg 67 Mustang and any aero mods eg cow catcher or 4" lift
Weight, curb front & rear and with driver
chassis setup

Obviously very few post all this info and sometimes it doesn't matter too much
Although for those guys in the 10's every little detail seems to matter.
So as you may notice I guess at a lot of stuff if not supplied
I probably forgot something but that's all I can think of

For the car, a "known" 60ft time helps, because the computer just cannot do this,
it depends too much on track, driver, setup, etc. Knowing the 60ft makes the
1/8 and 1/4 a lot more accurate, and you can measure 60ft with a Gtech just about
anywhere - I don't really count 60ft as a "prediction", too much luck and tirespin.

Damn kids with their drugs and rock n roll anyway!
