could be but the runners are not that short. they are about 6 inches from the flange to the top of the horns but yeah i will be gaining mid range for sure because of boost leaks before i was running soooo rich from 2k to 5.5k that it killed power badly. I have since fixed the boost leak and even when i went for a drive afterwards the difference was night and day, Soo much down low torque that i was missing before because of it was now there.
Again before the mani was installed.
Stay tuned. You will see some new numbers from me very soon. The trap speed will tell all. haha Im just hoping i can keep traction and launch hard with the new slicks.
