Well I finally made some passes at the track, and I am very happy with how things turned out.



Truck hooked well, for being a flip kit and tires. Caltracs were delivered today, so I should have those on and take it back next week.

 

There is definitely a disconnect between the dyno and the track. Not a little bit either. Unless your truck is like 6500 lbs. I'd call the dyno shop and tell them they need to get their dyno checked. I was expecting something like 120 mph.

Also, 19 mph back half is a pretty good tell tale that the truck isn't making power (like you thought anyway).

Not taking anything away from you or the truck. **** is bad ***. Just throw the dyno sheet in the trash and move forward.

 

The numbers are high for sure. but I would say based on an estimated weight of 4600 and your trap speed HP is closer to 520. any idea what it weighs?

 

Is this still with the ebay intercooler? If so, I bet your having bigtime timing pulled from high IATs

 

Senergy dyno has always read high......


Low mph could be from timing pulled, low rpm shifts and non lock up of converter

 

I don't have confirmed weight but I would say something in the 4600lb range w/ driver. This is still with the ebay cooler too. And correct I am not locking the verter at WOT. I don't think Yank recommends that as this is a 9.5 one. And my shifts are 6400ish into 2nd, and 6500ish into 3rd, and im coming through the traps at about 6200rpm

Honestly, I didn't even think it was going to go this fast. My intercooler and cals came today, so ill be back out there with maybe some improvments.

 

Actually looking at my slips, this run was almost 2mph higher. This was actually when the truck was fresh off the freeway too which is odd. But also the truck was shifting 150/200rpm sooner on this run.

 

with a slower 1/8 MPH to boot... thats a huge different on the back half.

 

Man, just seeing that slip makes me miss dragging. Always fun and a rush at the line no matter what the speed.

Faster first run in points towards IATs

 

Well hopefully that won't be an issue as my intercooler came in today and it's pretty stout.

Also, I wish I could log boost on HPT. I'm wondering if I'm getting some belt slip?
