    Increased Intercooler Flow?

    I know a lot of people just say to upgrade to the aftermarket intercooler to help lower temps.
    I've read where some people even want to provide the intercooler with its own source of water and dump it after the intercooler, effectively removing it from the engines cooling circuit.

    One thought that I had was to put a tee after the stock intercooler, on the water outlet side.
    Put a 1/2" hose on the side leg and run it to its own pisser to allow for more flow of water through it.
    Or even upgrade the stock pisser to 1/2" and tee the 3/8" stock pisser line into it, leaving it to appear stock from the outside.
    My big question, is there enough flow from the pump to provide adequate cooling to the engine with increased flow through the intercooler.
    I would love to do this if it helps, I just don't want to stave the engine of coolant.

    I wish I could just upgrade to the larger intercooler, but finances(wife) doesn't allow for this right now.

    If this would help get more water through the intercooler, it would help prevent heatsoak as fast as it does occur.

    Any thoughts or suggestions are appreciated.
    Thanks

    Be careful about generating parallel paths of cooling flow. It might not flow enough where you need it. I have modified all of mine with larger pump strainer/new 3 way valve with larger ports/ larger ports from the pump. Two of the three have aftermarket intercoolers/Macboost modules and shortened velocity stacks. They run pretty good.

    Stock the intercooler is already plumbed like that. Water from the Jet pump enters the intercooler first, then the engine.... You want some heat (at least 57C) in the engine.

    What ski are you running, I have redone the whole water cooling circuit on the F15x, I have all the schematis and pitcures on PWC, it is an awesome mod on the F15x and well worth the time and money to do.......

    I have an 04 r12x
    Its pretty stock
    I have repitched the stock impeller, which helped hook up faster and gave me about 1mph.
    I also have a home made version of the macsboost module. It's works pretty good.
    Once I put that on through, I managed to heat soak the intercooler really fast.
    If I punched it, it would run 17psi for a couple of minutes until it heat soaked then it would cut back to 10psi.
    I was wondering if I could increase the flow through the intercooler to slow down the heat soak.
    I have an intercooler that I modified, but I just need to find someone who can weld aluminum before I can finish it.

    Hey there Rich, just curious, what changes have you made, and what gains etc.

    Reason i ask is that im looking at making my own intercooler. Im a racepart fabricator here in Aus, i specialise in imports (Nissan and Toyota) so my options on how i can set the core up are limitless, but i do want to make it a worthwhile upgrade. However, thats not going to matter if the water plumbing side is going to let it down. I have a R-12X, so its somewhat different, but are are fammiliar with the R12, as in the changes you have made, are they common to both ?.

    Cheers
