For this episode we head back to EFI University for some schooling on camshaft modifications for boosted engines versus naturally aspirated ones.

The segment kicks off with Lake Speed Jr and Ben Strader in the dyno room at EFI re-capping their modifications to the Expo LS Engine from 2023 (Expo 2023 episode 30 and episode 58), and the results they got first with naturally aspirated and later with boost.

Then they dive into the dyno data, overlaying combustion and camshaft events to explain why they were getting torque at the high end, but losing it at lower RPMs, and detail the camshaft mods they would have t o make in order to recover the loss.

After the discussion in the dyno room, we head over to the classroom whiteboard where Ben lays out in detail how they used the engine data to plot the valve events and use that to make camshaft changes to fill the torque hole at the low end.

Another great educational session for any engine builder looking to up their game.
