Thanks.
When I watch the Hellion install video, they go up to 9 psi on the "shop car." I was uncertain if the shop car was basically unmodified or if there were mods allowing it to go that high. Or is it that they were just doing a couple dyno runs and they weren't concerned with any damage to the engine?
From the show 533(hp/tq?) at 4psi, 559hp/565tq at 7psi, 615hp/620tq at 9 psi.
The Hellion Kit looks awesome and seems to have a lot of potential to grow but I'm curious as to what "safe performance" someone should expect with just the kit alone without additional upgrades.
Given that heavy upfront investment, it'd probably be a while before most of us could consider making other changes to exploit this kit's greater potential.
