since I never see any post on stock bore bikes with head packages, I'll post mine. Here's the deal. My baseline dyno is how I bought the bike...bone stock with a full yoshimura rs-3 exhaust.
the "after" dyno is with carpenter racing's head with the .4xx lift cams, small airbox mod, short velocity stacks, pcIIIusb.
If i didn't list it (even the small stuff), it's not done, it's still OEM.
the pcIII was running a generic map off of the website, but the tuner done a little rough tune to make it safe, I'll take it back for a full mapping once I get the gen 3 brock system on here....I'm curious to see if that system will live up to the hype and make more power than the yosh. All I will do is change the exhaust, and re-dyno...then we'll map it.
I'll post the results of that test here too...exhaust should be here sometime next week.
*Note* the cams were degreed to maintain as much as the midrange as possible(so there's more top-end left, but I would sacrifice midrange; and this is a street bike)...I think this is a little too much head for a stock displacement/compression engine...I intend to add 12.5:1 stock bore pistons later in my quest for a realistic 200rwhp.
*just for comparison...the tuner said stock busas make about 150rwhp on his dyno (250I)... also, my 05 zx10r with a -1/+3 gearing, and full arrow exhaust made 146rwhp on the same dyno. Both bike run real strong...haven't been beat in a street race yet with either one
