Any good places to buy intercooler piping at, i want to redo mine, i am upgrading my bov and i heard its best to place it like 15" from the TB does that sounds right? TIA

 

Don't know about the 15". Why do you want to upgrade? Larger pipes?

 

I can imagine that the best size for your post-intercooler pipes would be the same size as your TB. I don't know thats fact, just guessing.
I don't think it really matters where you put your BOV. The shorter the vacume line to the bov I think would have it working faster.

 

The vaccume "signal" will travel down the vaccume line at the speed of sound, so length of the line doesn't matter.

 

what does it say in the book?

 

i would like to know that formula also. im about to upgrade my intercooler pipings but i dont know what the biggest size i can go.

 

Bigger is not always better. I'll be using 2" for my 1.6 liter motor with ~6-8 psi boost.

well, i kinda got lost of what u were saying. im using 84mm gsr, 10.1:1 compression, XS engineering T3/T04X turbo, XS engineering GTR intercooler and my pipings are only 2.25in. im thinking about going to 2.75in. but i dont know if it's too big. any suggestions from the experts?

 

 

the formula for figuring out ideal pipe diameter is on pg 80-81 of "the book"

it is :

velocity = airflow rate / area of section

it's a lot more complicated than it looks...I helped somebody with this a couple of days ago. I ended up drawing the entire sample calculation out of pg 81 of "the book", in JPEG format.

If someone has server space for a 40 KB jpeg of the whole calculation I can e-mail it to you, that way you can post it for everyone to see. I would post the pic myself but I cant find any free pic hosting sites.

I found a free pic hosting site, lets see how fast we can use up the bandwidth :D

This is out of Maximum Boost pg 81.
