How much would you Pay for a
HI all
I have a friend who has a line on the black box used by Kiyo Watanabe
Not sure if this is a Honda racing black box or not.
Spark Unit complete (Ignition black box)
This "black box" replacement will boost power and RPM rev limits. Different spark unit advances ignition curve, providing increased timing and rev limit at the "wide-open throttle" position.
Price - $450
I am in the process of finishing up a stage one motor with these parts. Thinking 10 to 15 present increase in HP

If I was spending all that money on a stage engine, the ignition would be the next logical step. If you don't buy it man, I will! I will have the same engine 
Smokin', I thought they (HRC) had a different ignition curve and removed the rev limiter?

It is likely the HRC box (like I have). As some have noted, beware the absence of a rev limiter (cost me a set of cams). FWIW, there is a new one listed on Yahoo Japan Auctions. eBay Japan site for about $150 IIRC...... You could also consider going the Ignitech programmable ECU route for less than $450......
