It's probably good for ~30HP. Considering the motor dyno'd at the wheels what Hyundai claimed at the crank an extra 30HP it's pretty serious. A 306HP at the crank V-6 will put down 240HP to the wheels with a manual transmission. Remove the crimp and the 4 banger will be right there with it.Unless if they seriously botched the whole engine design in the 4 banger, I can't see how removing that bend will generate anything more than 10-30 extra HP with the same level of boost. Fixing that bend and doing other mods could yield some nice results, but then you're talking about pushing a 4 cyl. engine from a company who isn't IMHO well-known for sustaining performance parts.
