    The tuner indicated he had tuned one 818 and later had to detune it to about 300 horsepower for reasonable street handling.

    That's a great power band. Torque comes on smooth and early. You have a limited slip in that right? And what kind/size tires are you running?

    We do have limited slip and we are running Falken Azenis 235/40R17s.

    Mr Miner at it again. Nice

    That was my 818. 300whp and 265 wheel torque with no timing advance to control heat and keep the car in control. Over 300whp is really just a waste of power IMO. I could have made like 400plus whp but I decided to keep it in the safe limits all around.

    Matt is the very best Subaru tuner you can find on the right coast. He can really tune just about any car perfectly.

    I agree, if you want a Subaru engine tuned and are anywhere near New England, this is your source. His leaning is to provide a safe tune (one that won't blow up your engine), but if your looking for something else, he will give you that as well. He has a nice method of tuning the cars and while the 818 isn't exactly the easiest car to put on the dyno, he spent over an hour tying it down to get is secured.

    How are these fans working for you?

    They didn't pass our poor man's R&D. They don't flow nearly enough air. That Plenum was finished better than in those pictures too. We had it sealed very well. Ideally this is how you would want the intercooler sealed but we could not figure out an effect way to move enough air over the IC.

    So we went with an air to water and called it a day.

    If I still have it, sure.

    Thought I have a feeling I tossed it... I will need to check the garage when I have a chance.

    I have a question about the IC.

    Is the stock AAIC not enough to keep the engine cool at 300hp and as a street driver?
    I'm trying to figure out if I need the AWIC (my build will be set up like yours)

    The OEM IC does not get sufficient airflow, IMO.

    I am with Jerome on this one.

    Without some body mods or some kind of ducting/plenum to get the air to the IC better, you will be better off with an AWIC.
