Default 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.

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 *** zip tie to tie it to the sway bar brace. I'll have to go look at that and rethink it maybe.
