I had a few 6 pak scoops on my car, I made a taller version to allow for a taller induction, but I noticed that the mounting points were getting hammered & cracking the fiberglass, even with extra reinforcing underneath. At speeds of 145+mph, the wind was hard on that hood so I changed to a cowl. No more hood damage & we even gained 2mph & increased e.t by 0.02. I'm not going forward facing again.
^^^This is what I'm experiencing right now been looking into cowl hoods but trying to find one that suits my liking is the issue. I'm not into the total brand loyal thing but like was said before 70 RR/GTX's came with cowls.^^^
