yes i was wondering on your piping on your manifolds what size do you use does it matter on size of manifold pipeing on turbo projects will it hurt my turbo car if i have to small size pipe what is the size that most manufacture's use on there products also i was wondering about EQ, how do you measure it to be EQ manifold i really like this site and yes im a newbi tryin to learn what i can... thank you for looking...

 

ok, i'm not sure what you are refering to with eq... equal length? most people use 1.5" butt weld fittings for their manifolds... most noobs use the search function before looking like a :1 good luck with your project.

 

yes i was refering to EQ Equal Length... thanks for telling me the size and all and sorry wasn't thinking of doing a search cause i was just leaving for work when i posted this...

 

ok was using the search engine on this site then tryed goggle and still havent found an article on how to measure the pipes for equal length please any info well help me out, im not currently doing a project but would like to know in advanced...

 

well it's pretty easy to determine the length of the straight pipes, i really hope you can do that

for the 90 degree bend try this:

say you have a 2" diameter 90 degree bend and you know the radius of the arc(distance from the edge of one end of the pipe to the center of the other end, measured perpundicular to the first end and parallel to the other) we will call this value "X"

you take that distance and double it to get the diameter which is "2X"

then you multiply by pi which equals about "3.14(2X)"

multiply that number by (90 degrees/360 degrees) because there would be 360 degrees in the circurmrence you just found(3.14(2X)), but you are only looking at 90 degrees of that circumfrence

so you would be multiplying (1/4)by(3.14(2X))

that is the length of your bend through the center of the pipe, if you want the length of the inside or outside of pipe, you can change the radius or "X" value to be the distance from the center to that particular edge

hope this all makes sense, if not I can do some photoshop, but if you not you should probly not be turboing your own car either, just a thought

 

im pretty sure i understood all that but send me that photoshop so i can double check and see if what i understood was correct or if i was wrong... but im pretty sure i understood what you said...

 

lol, all of that, couldnt you just say put two of the 90's together like an arc and measure the overall distance from one end to the other and then divide by 2. Then you know how long each elbow is. Theres really not much more to it, if you cut straight pieces, thats easy to measure, only difficulty would be cutting 45 degree pieces or whatever, but even those you can just measure as you go. Pm me if you need some more help.
