I/C piping question
 

Any disadvantages to dropping down to 1.5" for i/c piping? Having some issues with space constraints and wondering if it would hurt performance etc.

ive read somewhere that corky said 1.75" is enough to support 300 HP. I dunno though, 1.5" seems kind of small.

Quoted from m.net:
Has anyone out there done the math to know what the necessary IC Pipe Size is to support an engine making 300rwhp? I'm working on designing a IC for the Ubercharger that can support 300rwhp and I got to thinking about possible shrinking the size of the IC pipes if I can....or enlarge them to be able to support my end goal.

Just spoke with Corky, he crunched a few numbers (i.e. a LOT) and came to this conclusion as well that 2" would support 300rwhp no problem and I could even get away with 1.75".

2" pipes are small, dont see where you'd have any constraints....

+1, if you can't fit 2 inch pipes, you fail

2" doesn't fit too well becasue I have to run it down next to the a/c and p/s. Can't run it between the fans becasue of the sway bar and brace. I managed to reroute the power steering line a bit and the return line, So now I have about half inch of clearance at best. I'm not 100% happy with it but it will do for now. Getting rid of all that crap for the lower rad hose would be extremely nice though.

man up....it fits.

How hot does that p/s line get swapped around under the turbo?

that one actually burnt through :) I had since routed it back normally....

you can see my awesome use of friction tape for a temporary fix...the other retrun line had no issue.

I had a feeling you might say that lol, Moving the return line would definately help matters. I just have to find some hi pressure line. I would really rather go over the top with the pipes for simplicity's sake but the vent on the hood dips down too far for 2".
I have the pipes routed down now but only have maybe a half inch between the a/c and it so I don't know how much the motor will move around when I start it up again this week.

I only had this much room when i put it back together....never hits, since it moves WITH the engine....

Hmmmm I didn't think about it moving with the engine. I wound up using a hefty ass zip tie to tie it to the sway bar brace. I'll have to go look at that and rethink it maybe.
