    K20a type r dyno number

    Here's my dyno number tuned last spring

    218whp and 156wtq on a dynapack

    Mod are
    JDM k20a
    Injen cold air intake with velocity stacks
    Blackworks race headers
    custom 2.5inch exhaust
    Rdx 410cc injector
    Skunk2 intake manifold
    Hybrid racing throttle body 74mm

    I was expecting to be in the 22xwhp but i got hudge restriction in the neck(its bend to fit) of the cold air and my exhaust is not mendrel bend

    Nice. Not bad numbers at all considering they make 220hp at the crank stock. You basically were able to make up for all of the drivetrain loss.

    When compared to 05-06 RSX-S (K20Z1) the numbers are practically identical...

    If I had to choose I would probably just buy a Z1 and PRC manifold and call it a day.

    I would check your compression numbers, my friend with his 06 RSX-S pulled 217 whp Kpro tuned with just an ebay header, ebay intake, and T1R 63mm exhaust.

    Different dynos are going to give different numbers. That's a nice flat curve. That's all I'd really worry about.

    If I had to guess I'd say that's probably a case of a good Z1 or a high reading dyno as opposed to a bad K20A, just based on the numbers.

    Definitely.

    I can't see the dyno chart, whatever he's using as a image hosting the web filter on my network at work is blocking it lol.

    I want to get a copy of my friend's chart, maybe you're right, maybe it was a freak engine.

    After doing some reading though, I found that the Z1 uses the K20A intake cam...same part #.

    Wtf you cannot see the dyno chart ? Btw i use imageshack

    And for the compression it would'nt be a bad idea even if my engine run's well

    Yea I can't see the chart, US Air Force blocks imageshack and a few other image hosting sites. I forgot which but there are only a couple that they don't block.

    Run a compression test and come back with the numbers, you might be surprised!

    The Kpro ECU allows tuning whereas it sounds like this guy is using an OEM Type R ECU that's not tunable. Also, the T1R exhaust is helping your friend out a little too.

    Hey sir_2002! I'm curious what fuel you're using without Kpro? Also, I like the spike upwards after 8'500rpm. Looks as though she likes to be revved ;)

    Also, I like that a 2L engine is making 218WHP. That's one efficient engine! Go Honda go! Domestics need a 3.4-3.8L engine to make the same power.

    Some YouTube people would tell you that a Honda Type R anything is well into the 1,000,000's of horsepowers

    dynapacks read 7-8% higher since the power is to the hub, that 7-8% is lost once the power is transfered to the wheel.

    your numbers are very low for a type r motor with mods

    the low numbers are probably because of my bad tune...

    at first when i got dynoed at 217whp i was running 97mph at 1/4miles

    then another tunning ask me to send him the map and a datalog for etune (after a question on bad spark plug color i have asked on another forum)
    here the pic of the spark plug after my dyno tune 218whp not looking good...


    So the other tunner sended my the new mapping and i runned 100mph on quarter mile and notice hp in my butt dyno haha

    So i would have probably gain couple of whp on dyno with the new mapping

    I wouldn't call it very low at all. You're talking about a motor that made 220hp at the crank. There is also power lost between the crank and the hub. To make up these losses with the mods he has is nothing to scoff at.

    ive seen 230+ on dynapacks with similar mods on an a2, so with a better tune he should be making around the same.
