We just switched to a flat hood and a Makrolon clear scoop. It's sealed, haven't really got any conclusive data so far to compare it to the suitcased sized unsealed 6 pak but so far it has just beat it on mph and ET. I was going to put a sensor in there to log and see how much pressure was it was building, currently running 140+ on a good day, when the 655 goes back in we're hoping to see nearer 150, as it should be 200hp more. You can barely see it from a distance. ![[Linked Image]](http://i.imgur.com/WYDvuvA.jpg) ![[Linked Image]](http://i.imgur.com/bNutuoh.jpg)
