Interesting discussion. I have manual on my FFR and they are fine. It is 2k lbs though
. I'm undecided about which way to go with the Nova. I took the OE power setup off long ago when the plan was a street/strip car. Then I found Lat-G
. I knew it would be unlikely I'd pull enough vacuum to run power brakes. The Hydraboost seemed viable. There are even a few guys using the same setup on their FFR. Admittedly the recent crash of that Nova raises some concerns. I do think that is still an unlikely even though. Like anything, know the risks and move on/mitigate.
I also find this Nova crash it an interesting case study of sorts. Take Hydraboost with what I perceive as a good reputation for addressing a common want/need in the aftermarket. Then one high profile accident related to brakes happens, and almost immediately it is on many auto related forums being discussed/questioned. Marketing peeps really have to be on their toes to handle the efficiency of today's social media outlets.
