I would agree with that statement to a point.
I would also like to bring up that this is a forced induction engine. The charge or air has to go down the path you give it. It doesn't have to be "pulled" into the engine, making the high velocity work that much sweeter.
You see that area at the bottom of the intake in the second to last pic where Doug machines the bottoms flat. That impedes airflow. The air now has to fight to make it out of the manifold.
Chaulk me up for a stage ? How far you plan on taking these things man. The only reason I don't have one yet is because I'm waiting for the stage 10 to come out LOL..
I would have to disagree slightly with the last question. While it's true that a intake with an stock "appearing" EGR vavle will not flow as much air as a intake with no EGR system there are still a few little tricks that one could throw at the guys who desire the EGR system for smog checks, and...
The bolts going through a intake are only good for +/- 12 CFM or so. Meaning you only gain 12 more CFM by not having the bolts go through the intake. To me, the 12 CFM gain is not enough for me to justify possibly loosing one of those little 6mm cap head screws down a intake runner. Again this...
Let me add that the stage 3 High Velocity manifolds can be welded if someone wants to drop 3k on a manifold. I did an all welded HV manifold one time as a proto type. I had about 70 hours in that one manifold.
Forgot to add the the epoxy is far stronger then the aluminium.
I epoxy the manifolds back together. I do this because to achieve the high CFM gains you have to epoxy the inside of the intakes in places. If you epoxy the inside there is not way to mechanically join the two intakes peices back to gather because when you weld aluminium it distorts do to the...
I'm not sure how much I can say in this thread without being banned. I've had my hand slapped a couple times and really don't want to get banned. I can understand the concern for the other vendors here because I'm not a paying sponsor; however, my manifolds are sold by two vendors here.
I have...
Tape off the runners except for one intake hole. Tape off the top where all the power robbing crap hangs out. Turn the intake back over so you can see the runners that you taped up in the first step. Pour about 2 gallons of gasoline and let it set a couple hours. Pour gas out and rinse it out...
