See Below, and stay out of the big boy conversations for a while.

all three of which, go right into at the biggest a 1 x 3" pipe. this is why i find it funny when people argue about how much better a 1.75" primary header is than a 1.5" primary header the more volume you have, the slower the velocity. the slower the velocity, the less scavenging effect you have. so bigger on everything, isn't always better.
Your math is FUCKED up...

QTY 4 x 1.5"= 7.07in^2

QTY 4 x 1.75"= 9.62in^2

QTY 4 x 2.00"= 12.57in^2

QTY 1 x 3.00"= 7.07in^2

Wow, triple post, my bad...

who gives a crap about my math, the point of the thing is that 4 x 2" primaries is bigger than a damn 3" single pipe.

we can argue about african swallows being faster than european swallows in our next round if you would like, and you can calculate the which bird uses the best navigational method to travel from fixed points

and if you dumbies want to get really technical, all of your math can be wrong as well because we didn't specify the gauge of the tubing being used.

it's the simple fact that you came into this thread, tried to state "facts", all of which made no sense. Which does a number to your credibility. Your info was incomplete, and your logic and answers were wrong. Then you call everyone else dummies?? lol...

you're right nothing i posted makes any sense. the documents clearly state that more backpressure helps out on the low end EXCEPT in properly tuned cars, which means pretty much a custom tune and not one on the car off the factory line, and even then you have to get a good tuner that understands peak and WOT runs are 5% of what a car does. It takes a hell of alot of skill of which i would say less than a dozen people on this site have (myself not in the group) to be able to properly tune a partial throttle operation with the most efficiency.

If you want to argue the part about the backpressure vs. vvt, vvt changes the pressure wave about the same as more or less backpressure and/or scavenging would. i'm no engineer nor have i ever claimed to be so it may be hard for me to explain stuff technically in my posts. but what i do is build fast cars. some of which you could unplug 7 of the 8 cylinders and it would still put down more power than most of the cars on this site.

again the whole thing was initially about scavenging and velocity, not about backpressure so the argument can go away now

I was implying that you're fighting like a bunch of girls over math problems. what a bunch of losers.

when you understand more about cars, exhaust velocity, and scavenging, you'll understand the reason for the "math problems"

lawl. cars are nothing more than giant chemistry problems that make energy and turn it into a giant physics problem

Exhaust gases coming out of a motor are very hot, 1000+ deg F. Well that exhaust gas is hot, it has a lot of velocity. As it cools, its velocity slows down, thus you need to start reducing the size of the exhaust piping to keep the velocity up. So a bigger primary is indeed better for flowing those hot exhaust gases, but there is only a very small handful of people on this site who are supercharged that could even take in any advantage from that versus the amount of money it would cost to make.

Hey! Thats RD Fabs! They do amazing work with stainless parts. They are the first people to make a full 3" intake for the lsj that doesnt bulge the fenderwell AND they are also the first to make an exhaust manifold with 2" primaries for the cobalt. I know the guys personally and a good friend of mine has had ALOT of work done with them.

pretty but not equal length primaries if 2 inch mattered. On an SC equal length is less important than on a NA but for all that work? pretty....

I thought equal length only benefits with a turbo
