Thanks 3X5PSI.

It shows the PROcede power really kicks in around 3000 RPM. Can't wait for mine to arrive.

Cheers.

Dude I'm also down under the other side of the world with a Euro spec car. Used 95 RON with octane booster. Otherwise stock.

Where did you get 93 octane in Colorado. I have never seen it.

Thanks for posting your results up guys. It's nice to see data from the other side of the world And your comment regarding the ground wire on RHD cars is noted.

YEah we use kw & NM, instead of HP & lb/ft. But I asked for a graph with horsepower but forgot about the torque.

Shiv, thanks for all your help. You a legend.

Here's another graph from 5500 ft.

You have confirmed my suspicion that the turbos run out of steam earlier at high altitude. At 12,000 ft you have to shift at 4500rpm or so.

Is your vehicle a MT or Step?

I'm MT. And yeah the car does peak earlier up here. I've noticed that with all the turbo cars I've owned. SMall turbos are over-boosting to compensate & running outside their peak efficiencies.

But the 335 still has a big advantage over NA cars at altitude.

Mix in 100 octane (calculate how much you need using a weighted average of the octane) with your 91 octane to get 93.

You can find 100 octane there.

My car is RHD too. I hope I can handle the wiring difference considering my mechanical ability goes as far as taking the PROcede out of the packet.

Cheers.

Here's some VBOx runs at our test strip:

Stock:


Procede:



interesting that the 60' times are the same with or without procede. I guess turbo lag is turbo lag, no matter what you hike the boost up to. Someone please just take out the turbo's and put a friggin supercharger in there.

Problem with supercharger at altitude is that it does not compensate as well for altitude.

The super, being linked to engine speed, can't "overboost" like a turbo to compensate for thinner air.

the 60ft times have nothing to do with lag. In fact quite the opposite sincee you are at partial throttle during the first 60ft struggling for traction. The 335, stock or with procede, is essentially lagless if revs are kept above 2500rpm.
