197 cams or GrpN timing?

[bozothenutter]

182 with RS2
Which and why?
Both?

Might be combined with exhaust manifold with longer primaries

Help?

Mine made 212bhp peak and nice flat torque curve (159lbft peak) with 197 cams with 8 degree advance on inlet cam (no idea what group n means, actual degrees is what you need to know) supporting mods of rs2 inlet (original version) 182 exhaust manifold and 197 fuel injectors

Chris @efi mapped it and it runs and drives beautifully on road or track

197 cams is intake cam advanced 7-8 deg

Group N is standard cams with intake advanced 7 deg and exhaust retarded 7 deg.

You lose a bit low end on Group N i believe.

Thanks guys, swung it over to 197 cams for me.
Especially as mine's a daily.

Bump, how did you get on with this setup?

Is the 7-8degree advance on the inlet cam manually set? or is that tuned for

With or without dephaser on inlet cam?

It's manually set.

Retains the dephaser.
