How big is too big?

How big is too big for intake piping?

I am fabing an air to air intercooler set up and am going with 2 1/2" piping from the turbo to the intercooler and out of the intercooler up tward the intake. I wanted something that looked nice going into the throttle body but my fabbing skills are not the greatest. I came accrost a Vortec intake elbow off of an LT1 supercharger kit and am trying to decide if it will work. The only problem is that it has an opening of 3 1/2". I figured I could use a transition from 2 1/2" to 3 1/2",and run the 2 1/2 pipe up to the Vortec elbow. I might be making a mountain out of a mole hill though.

I dont think it will affect air flow at all but am not sure.

Here are some pics of the elbow.....

Ideas, criticizm and thoughts are welcome

Thanks!

small pipe into big pipe is no problem....may add another 1/1000th of boost pressure drop.

how much did that elbow cost and where'd you get it?

Dont know about cost but they come with an lt1 supercharger package.

well i doubt he bought the supercharger kit to get the elbow. He said he came across it.....so thats why i asked where. cmon color stealer.

He proballyed had a friend with an lt1, or its one of those things that just fall on your lap.

Ps the pipe looks nice on the intake, im guessing your gonna use it for an a2a system.

color stealer: why speculate...let the man answer for himself.

It is from summit (the satin one as I am sure you can tell). I actually bought it a few years back for my SS Camaro, when I sold it I sold the elbow to a friend who never used it. Well needless to say I bought it back (kind of a wierd cycle I know) from him cheep and plan to finally use it.

I did not think a diamater change would affect flow and boost pressure but just wanted to check.

Should look noce when I get done.

How much power are you making ?

Stock Skyline GT-R has 3" piping. Big power cars go up to 4" ....

Sean, I hear what ya sayn, Supra's and (it seems like all the import guys) run huge charge pipes, what baffles me tho is how they run a 2.25-2.5" pipe from the turbo to the IC and then a huge pipe to the TB. (lets see exit turbo {really hot air} exit IC {more compact air} but what the hell lets make the pipe bigger, (ricer face on)"heck I know the outlet of the turbo is only 2.25 but lets put uhh 4" pipe"(ricer face off). Point is unless you have a really high number of really tight bends you should'nt need pipes bigger than the outlet of the turbo. (kinda like the ol chain is only as strong as it's weakest link) ofcourse all this is just my verry humble opinion.

Yes - I was using each as storage for Skyline parts....

They are both rather large paperweights right now...
