These camshafts are designed for street and race cars looking to make power throughout the Rpm band from idle to there rev limit. Everyone does not have to rev to 11500 but can even stay at 8000 Rpm but will see a massive increase in power.
These camshaft idle nearly like oem. If the Nsx heads is port & Polish at a reputable company like 4Piston Racing you will see 380 cfm with a 37mm intake valve that is what the s2000 F series flow and it flows better than K series.
The only reason the nsx don't make power higher than 8000 Rpm is because the camshaft are very mild. The F and K series oem camshaft are much more aggressive stock that's why they can make power to 9500 - 10000 on stock camshaft.
Two things give power Rpm or Stroke, even with a stroker kit the Nsx has a very small stroke so to make more power is Rpm.
Two reasons for higher Rpm are:
•Faster piston speed
• More power
That is true Rpm can ruin engine and it can also make power with great reliability for everyday use if built properly.
The Nsx has one of the best rod to stroke ratio from stock 1.95:1 and with a 84mm stroker 1.81:1 this means it can rev high with reliability it just needs supporting mods like billet oil gears, RF-Yamamoto Oil Pan, valve spring.
Also just want to state that the JGTC NSX revz to 12500 - 13000 Rpm and that is endurance racing, even though they rebuild the engine every race day.
Danny car is over ten years ago and the nsx market didn't have the aftermarket parts it have now and it still don't have has much parts as the K,F & B even the D series have more aftermarket parts than the C Series. That is why I'm trying to bring these camshafts to the market and to make nsx owners still have reliability and power.
