Does the trans in the car now have the software modifications that your trans will have?

LOL, breathe there, big guy.

You know this is not indicative of the engine's torque peak but of the DCT slipping at 7.2 krpm, right? The dyno is preliminary. Torque is looking very linear until the slipping begins, so I would...

Do you have catalyst free downpipes?

I think that idea is absurd.

Because the N54 is a forced induction engine, the designers had to incorporate a totally separate vacuum pump for the power brakes and waste gate control because...

Sounds good. Keep us updated.

Lol at the car being fine with no O2 sensors. The N54 is closed loop all the time which means it takes data from the primary sensors and uses that to figure out how much fuel to give the engine under...

I would say that indicates oil is not entering the combustion chamber then. Oil could enter the combustion chamber from the intake valve seals, pcv system, or compressor side turbo oil seals. Oil...

You can't change duration with VANOS, correct? You can only vary the center line I thought.

Interesting. I don't think a leak down/compression test could diagnose valve stem seals.

You would have to pressurize the head port with the valve closed.

What do your plugs look like. I would...

Lol, I was just as confused. It's funny because it's not that complicated.

8000 rpm = 133.3 rps = 266.6 strokes per second = 3.75 ms per stroke.

Concerning overlap at high rpms reducing...

You are right. I was off by a factor of 2, possibly due to lack of coffee. It's annoying me that I can't replicate the error I made though.

I was also assuming it could not inject right at the...

LOL, love the avatar.

I hate the ER cooler's rear louver piece. Looks pretty restrictive to airflow. I would come up with a different solution for the rear. Maybe the same piece, but with the...

@V8Bait

Thanks, did not know this. I never made the connection between each 25% of injector duty cycle of a port injector = 1 stroke of a given piston.

FWIW, 8k rpm means each one of the four...

A dual trace log with the output of the high pressure sensor at the rail and the PWM input to the fuel pump might shed some light. Or if you could integrate a PWM input to the JB4 to log the HPFP...

Even if the engine did operate in stratified mode, it would only do so during part throttle cruising. Under WOT, it would always operate in homogenous mode because lambda must be below 1 when WOT, or...

The DI system would possibly be a limitation if it ever operated in stratified mode, but in the US the DI system only runs in homogenous mode (stratified mode requires a DeNOx catalyst, which is...

My setup is very similar to the DIY oil cooler found on the other site by user "boom". It just uses AN lines to connect the...

This goes along with what I am saying. The transmission dumps it's heat into the coolant, and the radiator needs to dissipate this heat. If you remove the heat from the ATF first, and then feed it...

I would drain the coolant once and fill with distilled water. Do the water pump bleed then bring the vehicle to operating temp to open the thermostat. Then drain the coolant again ( I recommend...

Setrab or Earls would be good choices. I am happy with my custom Earl's setup.

It's common for a little gas to get in the oil (blow by). Blackstone actually recommends you bring the oil up to operating temperature before taking a sample to allow the gas to evaporate. If you...

BavarianBullet is right on about Glycol. It is mainly used to prevent the water from freezing, it does raise the boiling point, but so does the pressure the coolant system is designed to run under....

And while you are there, you can contact other uses on this site about finding an escort.

Have you looked into transmission cooling or water wetter? I used water wetter and saw about a 10 degree reduction in oil temps. Cooling the transmission fluid before it makes it to the oil/water...
