Don't know. I would have expected better MPH from what you had to begin with.

In theory, for every .1 you drop off your 60' time you should drop approx .2 from your ET.

Assuming you can get traction with the new stall I would image you should be doing a 12 flat or better and pick up a couple of MPH.

MPH is about right for the power.

Really? Munz is running basically the same car but Calais instead of SS, running same MPH and similar times but with some 70rwkw less. That doesn't add up.

So what MPH should it be? I don't think it makes 330rwkw for a cam only car with a big convertor that's for sure.
MPH doesn't lie.

cause rwkw means fk all, he would have around 265rwkw on an mainline, all powertorques cars with a 232/234 and a 3500 stall usually sit around the 265rwkw mark.

if he wanted a quicker 60ft should have gone for a 5500 stall, 1.5's every day

Well yes, I did allude to that in an earlier post but if indeed it makes what it says it makes then it should get more MPH.

Really, that much difference between a mainline and a dynodynamics?

what makes the mainline dyno more accurate than any other? I had the intention the dynodynamics is the more accurate one considering they calibrate there dynos every so often? there is no way im making 268rwkw I was getting more power with the vcm 21 which was making 390rwhp with a 12.6@108mph since then I just upped the cam to a vcm 3 and put in the 3.9 gears and stall which got it to 440rwhp with a 12.2@114mph I cant be going backwards in hp

12.2@114mph is a good time, so your set up is ok at this level most Commodores that get into the 11's run higher mph than yours.

With your old set up vcm21 390rwhp@108mph doesn't add up either, mph is way low, my old VX SS 249rwkw bolt on did 111mph.

Maybe put the car on another dyno to see if making the claimed power, 114mph is 290rwkw territory, 440rwhp that's 338rwkw cam only through a stalled auto like to see that.

Mainline dyno's have fairly much always given results a little more conservative than Dyno Dynamics. Then there is also the question of dyno calibration, your print out doesn't show any of the calibration data (air temp/ pressure, intake temp etc) so that puts another variable into the equation.
