3" or 2.5" intercooler piping
 

Just wondering what will work better for my IC piping. I know the norm is 2.5", but will 3" be too big?

Re:3" or 2.5" intercooler piping
 

It's probably not going to give you a gigantic horsepower increase. I would think it would be better to match it to the throttle body and the intercooler. :-\

I wasn't really looking for any increases. I can get good deals on 3" aluminum so its more of a money thing. I was worried that 3" would be worse. Thats all.

Also, Dr. Boost. I pm'ed you about some of your stuff for sale

Re:3" or 2.5" intercooler piping
 

I'm not exactly sure how that would affect the boost, but I'm sure you couldn't tell a difference. I think 2.5" is just the common size most people use.

unless you are over 400whp...3" is by far...WAY TO ------- BIG!

it's just like running to large of exhaust on an N/A car.

you loose velocity while trying to gain volume movement.

go with 2.5" and no larger.

Re:3" or 2.5" intercooler piping
 

kvh, even 2.5 is too big, I'd say 2.25 at the MOST.

Re:3" or 2.5" intercooler piping
 

what diameter tubing do greddy or edelbrock kits come with?

Re:3" or 2.5" intercooler piping
 

2" is your best bet. easiest to find couplers for and a little cheaper and easier to use. i know a guy down here w/ a drag hatch and he only uses 2.5" piping and he's making 600whp. remember, the bigger the piping, the more volume the piping holds. the turbo has to fill all that piping w/ air, so the larger the piping the more it will lag (being the turbo stays the same).

Re:3" or 2.5" intercooler piping
 

Have any of you actually felt the difference between 2", 2.5" and 3"? :-\

Are you talking about penises? ;) Don't lie to me. I have not, personally felt the differance in the piping, but 2" IS way easier to find couplers for (and cheaper), and the volume capacity is true. *nods* - Matt

Re:3" or 2.5" intercooler piping
 

Well, yes common sense will tell you that, but has anybody actually felt a difference? I highly doubt you could actually feel a difference between any of them. I could see how the 3" could cause a TINY bit of extra lag, but I doubt it would be anything to worry about. Maybe it is? I'd just like to see proof of this.

2" wouldn't be cheaper for me because I can get 3" aluminum tubing dirt cheap. But if you say it is gonna hurt me I will just pay the extra. Thanks.

Re:3" or 2.5" intercooler piping
 

i have 2 inch from the turbo to intercooler and 2.5 from intercooler to throttle body...seems to be tits to me and i use a custom coach and a t3 48/60...

Re:3" or 2.5" intercooler piping
 

3 inch piping is gonna be a little harder to run i think

Re:3" or 2.5" intercooler piping
 

10" piping is the best.

Re:3" or 2.5" intercooler piping
 

go with 2.5, any larger is overkill.

Re:3" or 2.5" intercooler piping
 

Not only will 3" cause turbo lag, but it will be very hard to make it fit. Most complete kits use smaller piping, for example DRAG uses 2.25" from turbo to intercooler and 2.5" from intercooler to t-body. I say pay the extra for a little bit smaller piping.

Re:3" or 2.5" intercooler piping
 

unless you have a t3/t4 i would go with 50mm piping, i couldnt imagine having 3" piping, thats insane there no point just look at where the air comes out on the compressor side, you will have lots of lag with that size

Re:3" or 2.5" intercooler piping
 

Aluminum is a much better heat conductor than regular steel, you might have problems with heat soak... good lord ive never seen a turbo car with over a 2.5" charge pipe

Re:3" or 2.5" intercooler piping
 

so steel would be better than aluminum then. I was going for the weight factor. I never really thought about the heat all that much

Re:3" or 2.5" intercooler piping
 

I agree , I hardly see factory equipped turbo cars fitted with piping over 2". Most (VW 20v, BMW, turbodiesels, etc. ) most run 1,5-2" at most

Re:3" or 2.5" intercooler piping
 

3" chrome piping would look pimp

Re:3" or 2.5" intercooler piping
 

you *could* do aluminum with heat wrap
