ok did a few pulles this morning going to work, if the computer is right it says i'm pulling 51lb min, is that equal to 510hp, just something I read along time ago and was wondering.

 

Well based on what I have seen doing tuning along the way I do believe that it is fairly accurate and here is why. In using hptuners their is a custom PID for calculated horsepower(at the crank), can't take credit for this it's from 12SecSS over on hptuners forum. Well making a WOT run in 3rd with the converter locked in my truck like you would on a dyno the dynamic airflow lbs/min curve followed my horsepower curve pretty damn close. Then figuring my horsepower at the wheels based on my trap speed and vehicle weight and figuring % loss from the crank to the wheels the numbers match up pretty darn close on my truck.

I would like to get to a dyno soon to compare the numbers to see just how accurate this is. But from what I have seen in my testing and I have spent some time messing with this it seems fairly accurate but a dyno run will tell just how close.

 

I have heard this, yes. It is at least a rough estimate.

 

Well if its true then the litte ole 5.3 is makeing some good power n/a hahahaha

 

When are you headed back to the track?

 

It's no replacement for a dyno of course but I have found it to be a decent tool for tuning on the street to see where you are at say after swapping a cam, etc.........

 

Thanks klug, I understand what your saying, I hope its close hahahaha

Cory I will be going tomorrow night.

 

awesome, so how are you liking those new heads?

 

510hp
should be good for 11.80's right...

 

Cory Not sure just yet, been to busy to finish up the tune, its close 12.5-7 AFR

Lance hahaaha I hope so but very dought it
