horsepower estimator program
 

i am taking a proggramming class in college and was bored and wanted to try and get comfortable with using Visual Basic.NET. i remembered a long time ago reading in a magazine a formula on how to estimate horsepower with a given amount of boost so i decided to make a calculator. it turned out pretty good, but i think the numbers are just a rough estimate at the crank.
does anybody know how i can post it up?
here is a screenshot.

sorry sinister i used your avitar ;D

Re:horsepower estimator program
 

looks like your makin negative hp

Re:horsepower estimator program
 

wow, that r gay. at least let us click on some ----.

Re:horsepower estimator program
 

"SCREENSHOT".
i was wondering if anybody knew of a way for me to post it up or host it.
and it's not negative HP that thing in the bottom is Sinisters avitar with the tach

Re:horsepower estimator program
 

that thing has to be horribly inaccurate

Re:horsepower estimator program
 

Why can't my avatar be in it too? That's racist. 8)

Re:horsepower estimator program
 

tell you what stealth, if you have the formula and what you want in it i will program one for you :)

Re:horsepower estimator program
 

You should include the type of turbo an ----, and if its got an IC. But that would be getting waaaay too complex

Re:horsepower estimator program
 

i like how the red compliments the blue everything alse soooo well :D


hehhee, well upload it alreay, i wanna know how much hp I have with my 0 psi ;)

Re:horsepower estimator program
 

This type of program would NEVER be accurate for soo many reasons its mind boggling. You might as well just include stickers and wheel size when you make that program ::)

Re:horsepower estimator program
 

turbo size would play a big big role.

Re:horsepower estimator program
 

like i said it is a formula for a rough estimate at the crank that i have been using ever since i read it. i just wanted a way that i could use it with out having to break out the calculator everytime. ::)


this place is starting to be more like HT everyday :(

Re:horsepower estimator program
 

i wanted something like the boost guage from johnnyracecar.com but he took it off.

Re:horsepower estimator program
 

wow, queer eye for the straight guy stopped by my post ;)

Re:horsepower estimator program
 

Geez guys take it easy! He never made claims of accuracy! He is excited to learn something new, and is sharing the progress with us, which is what HMT is all about!

Send it to me, and I'll host it at www.tunertoys.com and send you the link.

Using .NET, you could also make it a webpage instead of a compiled app...

Update?

what he said ^

Re:horsepower estimator program
 

Here's the real shizzy. This is an ITR motor. I made it rev out to 12.5 to prove to some newb that removing his rev limiter won't give him more HP.

Wanna add a turbo?

The program is accurate to within 2% of dyno figures. Only problem is, you have to know EVERYTHING about your motor >:(

At some point, I'd like to build up profiles...only then will you know if retarding your intake cam adds a few extra ponies!

Woah! :o What a neat toy! :o

:o HOLY ----. thats pretty cool but i don't think my class will be getting to anything like that beings this is just an intro class and i don't even like programming, just have to take it as a pre req. :-\

Re:horsepower estimator program
 

can somebody that has had their car dynoed while boosted post your stock hp and amount of boost so i can compare to see how far off this thing would be?

Re:horsepower estimator program
 

Stock Ls/vtec

175whp / 122tq NA
263whp / 201tq 11psi

Re:horsepower estimator program
 

Tim, that ---- is cool. I've always wanted a desktop dyno. :'(

Re:horsepower estimator program
 

i got 305 at the crank and after subtracting about 10 percent to the wheels i got 274 :-\, but like i said it is an estimate. i just figured it would be a good way to stop all the stupid question like "How much hp will i make if i put x amount of boost into x engine".

Re:horsepower estimator program
 

16-17% drivetrain loss is usually on FWD honda's

Re:horsepower estimator program
 

well then with that i got 256 :-\, i don't think that is too bad for a rough estimate

Re:horsepower estimator program
 

I want that program tekPhobia! Can u hook me up?
Im guessing 210whp 205wtq n/a

Re:horsepower estimator program
 

where did you get crank power from? he gave you whp to start with.

is your equation simply [(HPxBoost)/14.5]+HP? That is insufficient to say the absolute least.

Re:horsepower estimator program
 

no it's , boost/14.7 +1 x stock hp.

but i guess it doesn't work so i'll use it for myself

Re:horsepower estimator program
 

^^^that formula there gave me 236hp with 135whp on my b16 and 11psi. on the dyno i made 246whp. not a bad formula.

Re:horsepower estimator program
 

i always thought it was good to use if i wanted to see a ballpark figure

Re:horsepower estimator program
 

Re:horsepower estimator program
 

Drivetrain loss is NOT a percentage.

Re:horsepower estimator program
 

I like that chamber shape.

Re:horsepower estimator program
 

Ok what is it.. ?

Re:horsepower estimator program
 

It's a new form of a fraction that cannot be converted into a percentage. It's posesses no true equations or values and cannot be divided into sections, nor can it be multiplied. It's not even a number. It's a scientific formula created to ---- the entire mathematical system up.

Didn't you know that? :-\

Re:horsepower estimator program
 

The drivetrain loss doesn't linearly increase when you increase the power of the motor. Hence it should never been stated as a percentage, as that percentage will only be true at one point in the graph.
And drivetrain loss is generally overestimated. If you were losing 17% of the power in the drivetrain on a 300hp car that'd be about 50hp just boiling the oil in your transmission.

Re:horsepower estimator program
 

Well, if your motor is making 175hp peak and you throw down 145whp peak on the chassis dyno, then I would call that a 17% drive train loss in power. WTF else would you call it? He wasn't talking about drivetrain loss at 1500rpm or drivetrain loss at half throttle. :P
