Why would those weights even be given?? Seems a bit irrelevant... Unless it closely resembles unit weightScott contacted me to clarify, the weights given are before machining. So those are the raw materials he is talking about. The machine unit will certainly weigh much less. I've updated the article to reflect this.
I think because if they look up a 150 pound aluminum stock most people might be surprised at the cost.Why would those weights even be given?? Seems a bit irrelevant... Unless it closely resembles unit weight
Um what? This could not be any further from the truth. Remove vacuum at idle from a car like an 2.3L ecoboost, see what happens. I can tell you, its not an increase in emissions. Its oil usage, smoke at idle, etc. You NEVER want pressure in the crankcase EVER. Applying vacuum to the crankcase is beneficial in ALL situations. At idle it allows proper oil draining, venting of crankcase gasses that aren't being pulled by inlet vacuum. Under boost applying vacuum, or at least giving ALL the pressure a place to escape, not only allows the motor to make more power, its easier on all components, and allows proper draining for the turbos. You think people add belt driven vacuum pumps to scavenge the crankcase on big power race cars because it doest't do anything? You should fact check before posting something that is incorrect.Emissions is the only reason you want vacuum at idle too. No reason you need it other than that.
We are working on cnc heads for N54 currectly. Then valve cover and catch can together.
