finally getting the car tuned

[Pushit2.0]

The dyno logs everything and you can look it up at anytime, I will give one to your bro if you want. Dyno settings: 4wd Center Viscous, inertia set to 80, ramp rate of 120, all corrections off, straps on the back only with a strap to hold it back so it does not pull up on the dyno, no knock showed up, NGK BPR7es plugs @.028, E-85, and 24.5psi of boost.

3rd or 4th gear? Why wouldn't you want it to pull up into the dyno? That is how you get traction on a Dyno Dynamics.

Here we go again. Here is a link to a post I made about the DD and why we use it the way we use it.

Long story short for this thread, if the car pulls up on the rollers you have the weight of the car putting load onto the load cell also. This will make the power read higher then if the car did not pull up the rollers. We did some testing with my stock 1g and the car would make anywhere from 140awhp to 210awhp pending how the car was tied down and the ramp rate. Also we did some testing with my Honda and the settings in the computer, and it would range from 80 fwhp to 225,xxx.x fwhp that is not a typo. The graph screen can only show up to 30,000hp and the snap shot file can only show up to 99,999 hp but tractive effort can read up to 9,999,999 lbs, which the computer showed 1,xxx,xxx lbs of tractive effort for the Honda. As long as you set the cars up the same each time and you see gains/loses from tuning thats what matters, the end all number is just that, a number. Just like any measuring device, two people measure the same thing and you get 2 different numbers.

Time to go run my car again and let it pull up on the dyno and see what numbers we can get.

[Shane@DBPerformance]

I don't know how you would ever get traction on FWD cars without letting it pull up on the roller some, if you hold them back too much, the tires will spin.

C'mon guys, let's keep the drama to the dyno day thread! ;)

Craig, when are you getting your car? We always check MPH vs RPM if we hear a car spin the tires or have the clutch slip, as long as the RPM is off the engine somehow it will show a straight line if the clutch/tires hold. This is a fun Q/A though.

got it like at 730

[Shane@DBPerformance]

So, is anyone not running E85?

Was that reving out to 8000? Time for an intake manifold. My wife's drops power like that too.

Mine drops off pretty hard after 7k on top too. I am also on the stock intake manifold.
