Horsepower Calculator

[mommasboy]

Here is a cool link to figure what your horsepower is on your truck. Its going to seem really really low, as most people think they have 350-400hp in their basicly stock motors. When in reality they have about 225... Oh, and this method of hp calculation has been tested and compared to dyno tests and they were very very close give or take 15-20 hp.

another good sit is key word drag race hp chart or <a href="http://www.moparts.com/moparts/tech/pages/hp" target="_blank" target="_new">http://www.moparts.com/moparts/tech/pages/hp</a>. click on index at bottom of page gives pretty accurate readings. i have fastburn 385 it was close by 30 hp off motor at 385hp according to gm. it shows 285 at rear.

[Mike]

oh God, posting links to Mopar sites, what has the world gone to?

[RON]

DOES\'NT MATTER WHERE THE TECH. INFO COMES FROM, IF IT IS GOOD OH GOD MAN USE IT. NOTHING WRONG WITH A MOPAR HAD SEVERAL.

[mommasboy]

I always thought it was funny that people have a fast burn 385 or a ZZ4 that is rated for 385 or 350 or what ever it may be. Then we put it on a dyno and it makes 300hp.

[bohn333]

Anybody know of a site where you can just punch in what has been done to your motor and get a pretty acurate reading on horsepower at the flywheel. All these sites ask for quarter mile times and i have never run mine. Something with what has been done to the motor and weight and gearing and give me a good estimate of what i\'ll run.

[mommasboy]

Ok buddie i did you a favor.



My own program says that you should make about



317hp@5248 rpm



354lbft@4108 rpm



And an estimated 1/4 mile time 14.23@99.68mph



(i guessed you weight to be about 2850 or so)

[bohn333]

Much thanks lightweight !!!!

[mommasboy]

No problem...if anyone else wants and \"estimate\" you need to post ALL of your specs. All the way from your carb size to valve size, kind of heads (not brands but are they stock ported, or worlds or fastburns ...etc) tire size...tranny, vehicle weight, suspension set up. etc. etc. etc. And i would be happy to give you an estimate on Hp Tq and 1/4 mile times with MPH.

[knudsonm]

What program you using? I have a really old DOS program but I think it is off by a bit.

Its a secret. You cant get this one anyway so dont even try.LOL.. It\'s not desktop dyno or desktop drag. they are way off. It\'s A secret of mine but ill be happy to post any #\'s for my buddies in here.

[duckaholic40sb]

400 sb .040 over, approx 4850lbs

[mommasboy]

You sure it weighs 4850....is it an s-10?? They weigh about 2800-3100lbs with a small block in them.



Anyway...here it is



356hp@5000rpm



426tq@3544rpm



With that thing weighing what you say it weighs your E.T\'s are only about 16.6@85.21



Also 3.08 gears with a 29\'\' tall tire it is killing your gearing down to like a 2.72 or so.

[Kory]

Hey lightweight do you think you can give me some numbers. It is a 77 4 bolt main 350 came stock with 210 horsepower.

Cant give you an E/T with out having an idea of your gear ratios, tranny,also tire size.

[dunnonuffin]

Still waiting....

[rudedogg]

thanks lightweight for the quick response.i am rather suprised of the possible ET.that is pretty quick for the combo. and altitude.we\'ll see in about 2 weeks.thanks again...

[mommasboy]

Here you go homer

Rudedogg, I was being kinda generous, you can expect somewhere pretty close to those numbers though.

[td_iwhs]

Hey thanks lightweight. I dont know what ratio i am going to be useing or anything like that yet. I just got the engine done. I just wanted to get some reasonable specs on the beast. Thanks for all your help

[td_iwhs]

yeah its me again....i was wondering if this rating is at the flywheel or at the rear?

[mommasboy]

Flywheel

For the record guys, there numbers are pretty accurate. I had my car dyno\'d in Phoenix and it put down 12.40@108 (250rwhp@5200) corrected for sea level. http://www.s10v8.com/images/smilies/icon_biggrin.gif Not bad for only a small cam huh? http://www.s10v8.com/images/smilies/icon_biggrin.gifhttp://www.s10v8.com/images/smilies/icon_biggrin.gif

Hey lightweight thx again. Here are a few little changes...just use the same old stuff excpt...rpm airgap edelbrock, a 294 grind cam with .519/.523 lift Duration .050 250/256 Lobe seperataion 110 ceterline 106

Thx again

[td_iwhs]

Hey before i forget i was just wondering what size of a stall should i use for my tranny. It is a 700r4 out of a 85 camaro witha a stage two B&M shift kit in it. I got the stock stall in it now....will it do or should i go higher???? Im going to be running a 294 cam so..any sugestions will help....will it kill me on mpg or what...???? thanks again

[mommasboy]

331hp@5489



366tq@4188



And yes anything is better than the stock converter. Like i have said before, if you are going to buy one you may as well get one with at least a 3000 stall. Other wise you\'ll just want a bigger one later. But make sure its a lock up style if your going to drive it on the street.

[td_iwhs]

Hey, i am running a 92 s10 shortbed witha 700r4 trannys with a stage 2 b&M shift kit. I have a 3.08 limited slip rear. My rims are 15x10 but i run a 12 in tire. Im not really sure on my weight so just make a good guess and put one in. thx a lot
