I am in the middle of building my first FI LT-1 for my current PTK project. What rings would be recommended for my build. I will be running about 20-22 max psi boost at the track and about 10-13 on the street( if good fuel is available). THis car will be mostly street driven. I have heard both good and bad things about the hellfire rings. They sound like an excellent choice, but before I buy I would like some of your opinions. Thanks in adavance!
