Hi all,

Just looking for some advice with a little problem I have with front bar/intercooler pipe clearance. I currently have a HKS intercooler kit and GTR front bar fitted to my car and the return pipe from the core interferes with the front bar drivers indicator slots. To get around this I have done what many others seem to have done and sand back a small portion the front bar to accommodate this return pipe, although as a result have made it impossible to fit GTR indicators (see picture).

I am going to replace this front bar very soon with the same style GTR bar and would like to avoid cutting the bar to allow the fitment of the GTR front indicators and avoid pipe sticking out. One way I can see getting around my clearance problems is to shorten the U-bend intercooler return piping by about 4cm, after measuring it all up cutting the pipe it would allow just enough clearance without requiring modification to the front bar. My only concern is if I cut 4cm of the pipe I will lose the raised "lip" on the end of the pipe and am worried if this is removed will I be asking for a leaking intercooler pipe or having the pipe come off under boost? This "lip" is obviously there to help prevent the hose clamp/silicon pipe from shifting under boost.

I can't see any other way around this problem apart from cutting the pipe, getting a new U-section fabricated (don't know how much this would cost) or just modifying the bar and living with intercooler pipe slightly protruding from the from bar. Can I get away without the lip on one section of the pipe and still get a sealed connection between the intercooler pipe and silicone hose with hose clamps alone? Any ideas or advice?

can you slide the pipe a bit further into the joiner, or even get the pipe cut a bit shorter. can you mount the cooler closer to the radiator?

Unfortunately the pipe is as far as it can go into the joiner and can't mount the cooler any closer to the radiator. It seems the only options are to cut the pipe so it can fit closer to the joiner or cut the front bar so the return pipe sticks out a little bit. But as I said cutting the intercooler pipe looks like it will work but will cut off the raised lip on the end of the pipe in the process and as a result may cause leaking pipes under boost. Does anyone know if this is the case or is it possible to get a new lip machined on to the shortened pipe?

you could always get a bead welded onto the pipe to stop any chance of the pipe coming out. doesn't even need to go the whole way round. just 3 or 4 welds about an inch long at oposite sides will be enough.

Yeah that might be the way to go. Cheers for your help!

      I don't like "actual computers" for in car use. They take time to boot up, have OS annoyances, and so on. Arduinos etc are ready to go a few seconds after power on, don't mind being agressively powere cycled, because everything is non-volatile, don't mind being shaken and stirred.

      As Fred would tell us, it's all about interpreting the rules. It's not a water sprayer, it's a water mister... But everything else you've said, 100%! Even a raspberry Pi would be great, use HDMI out for a display, and add a raspberry Pi CANBus hat to read values out from the ECU.

      Being a race car, and being in the era of the Arduino, one would think it would take little effort to build a controller to do the spraying based on a real physical measurment. Waaaaay back in the dim dark AS days, JE "designed" (as in, he had help) a microcontroller based intercooler spray system. It watched the difference between a temp sensor stuck on the core and one in the free air in front of the cooler, and if the temperature difference exceeded a (settable) threshold, it would activate the sprays. Thus, it only ran water when there was an actual need for water. If you stop to think about the actual physical things that are going on in that stack of coolers, there's probably at least a couple of triggering conditions one could come up with, and one could probably even run one pump with more than one solenoid valve, to allow water to be placed where it is needed, or at all points at once (if it is needed at all points). We're in the age of science baby. But.... I suspect that intercooler water sprays are on the forbidden list in most circuit classes, no? So only good for Targa type stuff?

      Could you modify this duct so instead it pushes the extra air through the radiator too and not down and out? For temps, I know it's not the greatest idea, but as a bit of a last resort, you could use a very intermittent misting spray onto the front of the coolers/rad. You don't want to be soaking them such that water is dripping off, but a small most on/off so that the water evaporates. That point of it constantly evaporating, rather than being soaked in water, will pull a LOT of heat out of the cooler. I'm literally thinking just the little mist sprayers for a garden from Bunnings. Being in a low humidity climate it will help even more! The other trick if you want to be ghetto is some shade cloth hung in the opening, and keep it wet. Pretty much now it's acting like an evap cooler on a house, but cooling the air you need to use to cool the radiator...   On a topic to think about too though, when air enters through the bumper, is it all nicely ducted from the edges of that opening back at a nice angle, or is it like most cars, and the edge of the opening just stops, and suddenly it's wayyy wider behind that? If it does the later, get it shrouded out at nice angles. When that opening changes too rapidly, it can actually cause a high pressure zone between the front bar and radiator, and limit air flow into that area, which means less air for cooling, as it effectively stalls the air, AND adds to drag...
