    Too lean? Dyno Graph Pic Attached.

    in Forced Induction Performance

    Posted

    Hi Scott, 4,000 rpm actually (at 27 kph per thousand rpm in 4th gear).  I aim for 12 to 1 from 3,000 rpm upwards, under that up to 14 to 1 is OK for fuel economy.  So I am not sure why it goes so rich at 2,500 rpm.  Other than that it looks OK, the power line is certainly smooth enough.:D

    So you're saying that the lean spike is at 4000rpm? OK then... (the dyno was done in 3rd as you can tell).

    Cameron,

    A bit of background info: I have a remapped Toshi (guy off the forums) std ECU and was last remapped for 1 bar. Then i have had it back on the dyno and boost turned up to 1.3 bar.

    What boost would be optimum for a GT2530?

    So with the ECU the way it is, my A/F is not dangerous? But if i wanna get better fuel economy, it's best that i get it remapped if i plan to run this sort of boost? But how can the graphs be so different before i hit any boost? Can the ECU automatically detect whether the boost has been turned up?

    It's a bit confusing to me.

    Cheers,

    Scott

    Intercooler water spray - Is too much water bad?

    Hi Mik,

    you had your kit installed on your wrx correct? And with the stocko top mount cooler? How would this kit go on a car with a FMIC?

    Do you have pics of the setup?

    Cheers,

    Scott

    You want the mist to be as fine as possible. On my subaru, I had a water spray set up that used very fine nozzles. The way it was set up, a very fine mist was sprayed in the the bonnet scope in front of the intercooler. The water would vapourise as soon as it touched the coooler or even before, therefore cooling the air.

    I have seen a few people do tests on the track. Someone found that garden nozzles which used about 1L/min actually cooled the intercooler much less than misting nozzles which used one twentieth of the water.

    When I set mine up, I used three brassnozzles designed for evaporative cooling which I imported from the US. The nozzles are made specifically for cooling sports stadiums and the like.

    If anyone is interested, I still have the whole kit inlcuding nozzles, adjustable hobbs pressure switch, relays, switch and a custom made electronic controller which holds the pump on for 5 seconds after boost drops (keeps the pump going between gears). I'm willing to sell this kit as I no longer need it.

    I'm just waiting to see what pans out with all this before i decide to become a member. My brother is and has no idea with what's going on. What about all the people who signed up and don't have net access? Do they know what's going on with their memberships?
