Car feels slow - Need more powa?

[mattr66]

I tightened up everything on the intake side, nothing was loose but doesn't hurt to check.

Went out and did a datalog on the SCT. IAT was showing around +10F over ambient.

Here are some pics from it, if you notice anything that looks off, let me know. I broke it down so it is easier to compare data points.

Boost over RPM, all runs are same data from 2200 to 6200 RPM. Seems to be between 13 and 15.5 psi throughout the pull.


IAT over boost, coolant and RPM.


Line Pressure kPa over boost and RPM.


Spark advance over RPM.




Finally, my disappointing Dragy runs from today.

Chirped the tires off the line on the first run.




I want to make sure I have everything on my end covered before I start bothering Matt.

Are you not brake stalling your car?

Put car in drive, hold brake and floor gas pedal, car stalls to around 2500 RPM, let off brake and keep it floored, pretty simple stuff. It also makes little to no difference with traction control on or off as the car rarely does more than chirp the tires.

The pictures I posted from the SCT stuff was just a 3rd gear pull from 2200 to 6200 RPM.

Anything I need to look over on my end before sending you the datalog?

Uh...whats break stalling? Putting it in gear, hitting the breaks, then revving it, then dumping it on launch?

Usually referred to as brake boosting

For beginners, hold the brake, bring rpms up to 1500 then when it's go time, slam the gas and let off the brakes simultaneously.
