Works for me? Try clicking the volume knob on the video. It may be defaulted to zero.

Hi dave nice video, who dynod the car was it at the heffner facility?

No, it was at a local dyno near where I live, Livernois Motorsports. At Heffner's shop it did 837 on 93. This was on C16 with one turn of the ole' boost knob.

I wish all you hotrods would quit posting this crap. I start shaking everytime I see numbers like that. I think the only cure is to join the club.

Freakin' awesome!

Dave your gal sounds very nice

I do have a couple questions;

1. It would appear that this was a 4th gear pull; correct?

2. Now this is the biggie; the torque and horsepower do not cross at 5250; why?

In all my years the only time that this has been the case is when data is being skewed which is why I ask.

Thank you

his data is not skewed. the graph has not been properly scaled on the printer. thats why his HP and TQ are not crossing at 5,250 rpm's.

4th gear in a GT is not 1:1 > its .94:1

I know that 4th is not 1-1 I was looking to confirm that they did a less than rather than more than pull.

Now as for the printer; you lost me on this one.

If you are saying that everything should be moved over by 1200RPM then the pull began at 1300RPM; I must be missing something becuase this certainly was not the case in which case my comment about skewed remains; at least for this moment in time.

Regardless I appreciate you comments

The graph is just a little screwy, but everything seems to be kosher. :thumbsup

DBK - only "one turn of the knob and C16".

You quickly need to get runway clearance, you're approaching lift off.

Your time spent is very much appreciated; I did not look at the edge columns next to each other.

I never questioned the results but rather was looking to see how the torque and horsepower danced together.

I go back to my original comment; she sounded very nice and I have always enjoyed seeing the OEM style integration of the systems that Jaysonand his team create.

Takes care and thank you again
