It's not ideal, but it gets the job done. Trying to dump 30+whp out of a BP without mechanical restriction is hard to do. After you drop the timing to ~18* and actively tune the VVT to be as far from ideal as possible, adding fuel is all you can really do. Regular oil changes are encouraged.

The USDM NB1 manifold seems to make the best low rpm n/a torque of any of the OEM manifolds. VICS crossover is usually set between 2000-2800 with dyno tuning. Which manifold we use depends on what the project goals are. Our 2013 PTE cars all used a USDM NB1 manifold for the extra low end torque. Since we're capping high rpm power anyway, it's better to choose a manifold that makes teh least peak power to start with. This allows more timing for better BFSC which matters for enduro.

Couldn't do it all the way through, as that would harm torque. You could open the butterflies down low as E said, then flip the butterflies back closed once you get close to the power cap, though you'd probably knock 2-3whp off the peak by doing that. On a fully-built PTE motor, you need to pull ~35whp at redline. Small drop in a big bucket.

Bump of an old thread:
What did you use for windows in this beast if the weather wasn't cooperating? I noticed you cut out the front triangle from the door (which is what I want to do with my build too)

IIRC he used these:
becauseracecar
But in all honesty, I don't think there was any provision for windows. I seem to remember Crusher in the rain at MRLS with no windows. They made me run hardtop with windows down through the torrent that weekend with stock interior and my car has never quite smelled the same since.
