Contour Enthusiasts Group Archives Forums Branches South Central Demon, I got my new intake manifold for my Maxima. I've got a ?

Thanks. That's what I figured (mostly). I wonder why more companies don't use setups like this? It's actually a very simple idea that goes a long way in terms of performance. Now I'll just have to install it, but that shouldn't be too hard. It will just take a good 5 hours or so to get the manifolds swapped, hook up the Harlan RPM switch, vacumm system, and relay. I'll need to tune on the dyno to find the best RPM switch over too. I'm figuring I'll set it at 5200rpms (HP peak at 5300) to compensate for the valves opening and chamber becoming operational.

I can't wait. My Max will have some serious "legs" on the topend.
