Racing Beat Peripheral Port Housings?
Figured I'd start this thread since I'm interested in these and there seems to be no info on them in here. Anyone tried/running them?

I've tuned engines with them, later opening/angled ports such as these and some other home brew periphs I've seen in some SCCA 12As tend to be more midrange-y than many of the earlier opening MFR and PR/drag oriented configs I've been playing with.
Also, yes, about 310 crank only revving to 8500ish is what I've seen repeatably on a couple relatively unomptimized setups - there's definitely more in there however it'd be some work to get it.

I had inquired about them for their NA application and it seems to be catered to drag racing or a tight ratio gearbox as the power is very peaky, didnt suit my application or gearing but a nice option for others!
