@ 3700 raceweight and 365 rwhp, that means I'm at 12.60 ET

[Alleyoop2]

Cool, mines pretty close to what it says

[Z28SSMAN]

Actually...I was kidding...I ran 11.80s a few times but usually 11.90s to 12.0s. So some cars it works and others not so much.

With in .05 sec using rear wheel HP.

Mine is way off too, I don't think it takes torque into consideration.
I like this site.

That's a nice site Eddy. Still doesn't match my car. 3700 and 365 hp= 12.61. Or 115 mph and 3700 lbs = 462.50 hp or 11.95 and 3700 = 428.53 hp. I guess mine is "smoke & mirrors".

Must be the driver, or the fact that it's a stick or maybe GM just built it with the wrong parts or maybe it has a couple of ???

Yeah..there's no doubt have plenty of torque. What around 800 ft lbs or more?

[MR.hp]

Mine said with 348rwhp I should be going 12.3, Way off, last run of 2012 was 11.79 huh! Maybe I am making more power? It also says that I am making 600rwhp to go 10.17 but the car went 10 flat.

This one is not even close with my car.

[Z28SSMAN]

This one matches my ET except the mph is 7 mph low.

That one's not even close with my car. I wish it was, but unfortunately it's not.

@ 3700 raceweight and 365 rwhp, that means I'm at 12.60 ET

@ 3850 & 403 RWHP, my GN should run 12.36. My best run was a 12.76 @ 108.1 with a 2.2 60' on street tires. I've heard that my 60' should be closer to 1.8 sec. If my 60' was where it should be, how much would it reduce my ET?

Going by weight & HP, that one says I should be running 12.36 @ 108.4, so the MPH is pretty close. Weight & MPH says my RWHP is 399, which is also pretty close.

This one matches my ET except the mph is 7 mph low.

That one says I should be running a 12.14 @ 106.52.

These simple calculators all use single-point data, which means that many assumptions are being made regarding area under the curve. So, they'd only be in the ballpark within a certain range of HP & torque curves - right?

race precision was dead nuts on with my n/a crank hp, but 100hp off with my bottle hp. IM guessing eddy was right it doesnt take into account big torque numbers
