its actually kinda accurate.
when i pulled a 12.80 i weighed in about 2550 or so and was off tune so was only like 240-250whp and tihs came up pretty on .

 

is the calculated hp flywheel or wheel hp?

 

It looks to be at the wheels from the numbers I got.

 

yeah its to the wheels. i think its acurate

It will tell you both if you use the last hp calculator.

 

NOT accurate at all for fwd cars. says i could go 9.80's @ 137 mph with 510 to the wheels in a 2500 lb car. yeah, if i was rwd.

 

preaty acurate

 

yah, said my car should do 9.55 with my weight and mph. But it did say that with my 2475 and 141 traps, that i was makin 540, which maybe accurate, i dunno

 

186.55398651234728 HP from my EF-- 2320 pounds and 101 trap speed stock block b16, nice

 

Estimated Horsepower might be accurate, but the dame Estimated 1/4 E.T. sure is way off It says i should be running 1/2 a second faster

Its reasonably accurate it say's with 215whp and 2300lb car I'd do 12.8 that would be about right for an allmotor car or FI on slicks hooking up well.

Well it's wrong for me, the same goes for Jinx and Sixty Cent

no, actually thats pretty bad. with 215 to the wheels weighting 2300 lbs, in an allmotor cars, you would be running 12.20 easy. maybe 12.10. the calculator is as off as all the other ones on the net.

for the record, my old NA car went 12.40's weighting 2300 and pulled like 205 on the dynojet.

 

we did 12.2's @ 111 mph on a 92 hb weighing 2400 lbs. i put out around 210-215 whp.

this **** is way off for me

i put in 2500lbs with me in the car (91 gutted integra/i weigh 215lbs.) with I/H/E on the stock b18a. and i run a 15.2.........says i should have 182hp at the fly. BULLSHIT. i'd be lucky to be pushing anywhere near 150


Your integra weighs about 2500 pounds and can complete a 1/4 mile in about 15.2 seconds. That means that you've got about 140.70 HP at the wheels, and about 182.91 HP at the flywheel. &lt;&lt;&lt;&lt;&lt;total BS

 

These things are never accurate for fwd vehicles, but it actually wasn't that far off for me. w/ 109 trap @ 2620lbs it says I made 265whp... which is pretty much dead on for when I ran 12.89 @ 109.. Then for ET it estimated it thinks I will run a 12.50 @ that power/weight.. Definitly possible if i ran it on slicks.

according to that thing i only need 400hp to run a 10.6 at 126..yeAH RIGHT!

 

HEHE THIS THING IS A PRETTY COOL THING TO MESS AROUND WITH BUT I WOULDNT TRUST THIS JUST LIKE I WOULDNT EVEN TRUST A G TECH, ONLY WAY TO REALLY CALCULATE IS TO STAGE, LET THE LIGHTS DROP, AND GO FAST!

 

Seems pretty good to me, atleast for free.
For a few seconds of your time you cant expect perfect answers.

 

pretty good in our case. Thanks!

 

pretty accurate. :-)

 

considering that its calculations are for rwd cars its pretty accurate for me. says that i should be in the 13.7@99 range if i am making 175-180 hp and weigh 2300lbs....
my current best is a 13.7@99.96 with a stock h22a in a gutted civic and my 220lbs in it.

 

PLEASE dont flame me for this.

Maybe its showing you that you need to learn to drive your car????

Was pretty accurate for me.

I think I'm gonna get hammered for this one
