big hp slow ets

[VZSSCHASE]

yeah thanks for clearing that up, it was up around 540lb on another dyno whatever that is to nm, worked out that's a 55hp difference in both dynos.

Still up there with 540 ft-lb = Brake Mean Effective Pressure of 15.42 Bar, means your camshaft raises (torque per litre) to the same as a Formula One engine or a high performance turbo. Just saying if that is indeed the case then your HP is way way low!
If I were looking to get more speed on the strip I'd want better information from the dynamometer.

 

[VZSSCHASE]

if that's the case look back a few pages and you will see the dyno readout showing the torque and hp from a dynamics dyno and tell me your thoughts ?

page 2 to be exact

dynamics dyno

mainline dyno

can someone explain if the tune is right and is it running lean or rich, basically got no idea what im lookin at just the hp reading

and with that can I be running better times than 12.2?

picture #2 shows it running a little lean. I would think around 12.5:1 @ WOT would be the target,
although there is a dip around 6000rpm where it richens up a little, and then lifts again when it leans back to 14:1afr.

Would be nice if they showed you your power from 3 or 4k upwards instead of 5000rpm up. What rev range do you use when racing??

1000nm wtf????

1000nm wtf????

Yeah the torque is not displayed properly in any of the reports, and I've never seen a plot begin at 5000 RPM for an LS either. OP wants to know why big hp (380hp is not so big) gets slow et.
My bet is that 12.2 is on the money for 286rwkw.
No fricken thanks to the dyno operators, like I said if it was my money I'd want better charts, they are all ****.
The torque curve under 5000 RPM is important to consider, would explain a lot more, fuel leaned out to milk hp but not ideal for run or longevity.

Bit of a dip at 6000rpm maybe valve springs? not sure, the graph doesn't look right motor seems to make power very late and what Deuce said 3k and up would be nice.

Who put your cam in.

update ran a pb of 11.6@116mph with 1.566 60 ft and a 12second pass spinning the tyres on slicks at 3000rpm but did 2 passes with an 11.6 so im pretty happy if that's the power in making so be it.
