Yeah, me too. The cutout wasn't only for cooling though, it also allowed easy access to my roll bar that I used as a carry handle before getting the wing. I haven't run the .32 yet, but I needed all the help I could get when I was running the 454 during summer in the states.
Thanks, I look forward to getting the break in finished, hopefully I'll be able to get the first couple of tanks through it tomorrow and hopefully be finished by this weekend. I'm really looking forward to getting my ERCM pipe, hopefully it lives up to the hype. If it does, I'll have to order a truggy version for my Tamiya 801XT and a couple small block versions for my Traxxas trucks. The one being made should be similar to this one,
