I entered my info and it says
Peak Horsepower: 283
Average Horsepower: 300

What I dont know is if its RWHP or FWHP.
I also took the 1/8 mile time off my slip and ran it thru the "convert your 1/8 to 1/4" calculator and it was incredibly close.

I would say it is BHP not RWHP. It says I have 317hp And all I have is a set of GT40 heads, Cobra intake and full exhaust. Wonder hoe accurate it is.

Yeah I agree But here is what I am thinking, It is useful to compare runs on the same car.

For example I took last yrs best run and the track weight here is what it said
Peak Horsepower: 274
Average Horsepower: 275

Now with the mods I did over winter I used same calculater it says
Peak Horsepower: 283
Average Horsepower: 300

So I gained 25 hp basically.

mine was the other way around
302 Peak
286 Avg

I will tel you what. It hit my lightning right on the money. I am not lying either, don't belive me. Enter 13.50 at 105 with a 4600 weight

Peak Horsepower: 369
Average Horsepower: 415

Ok now here are my Dyno Numbers

Jk - somethings wrong there, your average HP cannot be higher than your peak. Was that supposed to be 315 average?

 

[OonDeanisS]

no it says on that site that the average can be higher due to a lot of variables

 

[tmoss]

Don't know how that could be. Look at a torque curve or HP curve - it has values on either side of the peak HP that are LESS than the peak. Since an average is the total of all points devided by the number of points, it can't happen!

 

[Jkstang78]

Tmoss I think your on to something there. But that is what the site said. But I was suprise to see it hit my max h.p.

 

[tmoss]

I don't trust any calculator that puts averages higher than peaks.............just me!

What it actually says is that the peak horsepower has to due with the e.t. you put in, and that the average horsepower is due to the mph. So if you spun and got a high mph, but not a very good et, it will show up wrong.
