A couple of friends of mine have been pushing the S54 turbo setup for quite a while now. They have togheter with PPF in Sweden been thinkering with the dual vanos setup witch is a big gamechanger in producing mid range torque witch improves driveability and power delivery insanely.
This week one of them (driving a E30 2 door with a fully buildt S54B32 with BW380 80mm turbo and 1060whp (2.2bar) / 1130Nm(@6300rpm) and E85 fuel) took the car to a track day festival and let it rip.
Another friend of mine, with a E21 (The former YouTube 1000whp silver one): also has a fully build S54B32, this time with Precision 8284 (82mm) turbo. He also uses E85 fuel. He went to PPF and dynoed in their Dynpack until the figure on the screen was 1167WHP / 1300 Nm torque (6500 rpm / 2.2 bar) - and then followed by a big red ERROR message from the bench. It couldn't hack it any more! They had to reduce torque in mid range also.
So they pegged it down to a Dynapack friendly 1111 WHP & 1100Nm ;D
Both cars are mapped by PPF in Sweden witch have been developing these S54 dual vanos setups for some years now, and use MaxxEcu's from Sweden and have a preloaded program witch enables them to set up the engine very qucikly and cheap. Setting up dual vanos cams in the ECU could take days of testing, and many tuners don't even manage to set them up even remotely correct.
To give you an example. A PT7675 on a non-vanos S54 can do 1000whp. With vanos it can only do 850whp because of the back pressure difference. That is sick!
