One more thing. With the small 76mm turbo stock vanos was the best! But the large one gained a lot with the cams opened a bit more before 6000 rpm.

Would you mind going into a little more detail? I've always been curious as to how vanos and boost interact and there's been a decent amount of opinions thrown around either way. Thanks!

Sorry for my bad english but the short version are:

If you advance intake and retard exhaust camshaft you are creating more low rpm torque. That also helps the turbo to spool sooner. I tune this in steady state mode every 500 rpm and looking for where the engine makes the most power, and looks at egt ,backpressure and knocksensor numbers.

Did you use the Oem cams with the larger turbo ?

It sure would be fun to see the power gain and the difference between them,do you also use your pyramid ring headgasket on the S54 engine?

Yes, we're going to try some real turbo cams with much higher lift!
Then I think we're going to recieve more power.

It's really easy to make statements and not back them up with data, but that doesn't fly with me. You can get by with that with the people who don't do this stuff or do the testing to prove their statements, but not with me. My testing disagrees with yours. So, if you want to back up your statements, then post proof...I did, why shouldn't you have to?

I encourage EVERYONE to do the testing themselves...don't take my word for it either. You just have to know how to do the testing properly, you can't start upsetting the stock ecu by removing sensors and expect it to run the cams in an optimal position. The cams move based on volume of air. They use this to optimize airflow through the engine on power demand. They ALSO use cam movement to reduce power when things aren't what they want.

1040 hub hp....your making about 50 more hp with an 82mm turbo than I make on my car with an 67mm turbo. All I have to do to beat that number is push a button!
I and alot of other people in the know disagree that vanos control does not net you power or at the very very least torque!

I was just wondering that now some of the euro guys are getting on the forum that now I can say to all the non believers I told you so about what they do in europe :p

I have tested vanos and no vanos. The difference at the same boost levels was 100hp, near on doubles the torque and brings boost in 1000rpm sooner.

Coming from supras Ive never played with vcam tuning so im curious -- have you found any need to vary vanos based on load? Or does one setting at a particular rpm work from cruise through wot?

It's load dependent. If you make the cams aggressive under cruise it doesn't run smooth.

There are also fuel economy implications as well...when you advance the intake cam at lower engine speeds...you bring in more air requiring more fuel. So typically you keep the intake cam out until power demands the cam movement.

When you did this was the OEM ECU controlling the cams and was it throwing any codes?
