High HP Guys Not Using BS3 - Knock Sensor Question
High HP Guys Not Using BS3 - Knock Sensor Question What are the guys pushing 1000 plus doing about knock sensors when running a tuning software such as HP tuners? I know that BS3 allows you to eliminate them and run a valley cover that is solid with no provisions for sensors. I am not for sure if I will run into problems though if I keep my knock sensors and tune with HP 3 bar. My setup is in my sig fyi.
Any help is appreciated.
Thanks,

Thats what I've heard. I have a book on High HP LS1/6's and in it, it showcases W2W building an F1R C5R 427. In it, they use a solid valley cover and mention that they tend to favor it in high boost applications for the very reason you mentioned. I'm just wondering if that's definitely a problem or a nice to have, piece of mind kind of deal. 
Oh...you can make anything fit 
Seriously though...It can fit in there with the supplied J bracket from Procharger. The thing is though, fitment of the air cleaner for daily driving is tough to get on...but if you're going strip only w/no cleaner...no prob.

i would definitely not worry about the knock sensor seals being a problem with FI. if you are blowing past those seals (with proper crank ventilation elsewhere) you have big big problems.
i bet w2w was running a lot of crankcase vacuum and is why they needed to be sealed up.
also no knock control with bs3 is standard, but i have run knock control on mine for a while as well.

I don't plan on running a sealed crankcase, so as long as I have a good vent elsewhere that isn't causing restrictions enough to put a load on the knock sensor seals, I should be good.
Will a dry sump setup pull enough vacuum on the bottom side of the crankcase with the scavenge lines to cause any issues? I don't plan on running a vacuum pump like Kurt mentioned, but I will probably go to a dry sump setup once I decide to turn more RPM's.
