Hot pipes?

Hey...i was just wondering what a hot pipe is and what it does. I say them for sell at www.heavythrottle.com but they dont say what it is and what it does.

Basically it's the part of the intercooler tubing that has the the blow off valve on it.

So lets say i buy a intercooler kit (i.e. Greddy R SPL) and it comes with piping do you still need to get buy a hot pipe?

I'm not sure, but but hot pipes are like a short cut, it's the pipe that crosses over the top of the engine that you see sometimes.

Ohhhh....is it the pipe that runs the blow off air back in to the intake system? If 240's are like eclipse's then not running the blowed off air back in to the intake system will make the engine run rich becuase its already been accounted for so the ECU see more air so to sends more fuel but the air is then blowin off. Is that the way 240's are with the SR20DET in it?

yup most turbo cars are like this and do not take well to bov vented into the atmosphere..

There is a BOV that vents to the atmosphere and back into the intake but I don't know how well it works. Anyone?

Hot pipes are what connects the Turbo to the Intercooler.(before cooling = hot air) they arent included because many people have different turbos and want Different BOVs

Recirc blow off valves are better than VTA because they wont cause stumbling from being overly rich due to all af the air being lost after the MAF

^^^ what he said

but open atmosphere bov's are soo much more louder :)

How loud will close loop (back in to the intake system) be?

So today I heard that a SAFC will fix the stumbling problem. Anyone?

Apparently not.
