Ok. please forgive a newbie for asking what may be a stupid question.
Let me preface by saying that I run in a club class that mostly follows the AKRA BS rules, the exception being that I have to run the steel billet flywheel and a blue restrictor plate on the carb. The engine is setup with the BSP-2 cam and 10.8 pound springs. The carb main jet is a #39. The preferred gearing is 15/56. The flywheel and keyway are in the stock position. i.e. no advancement in timing.
Clutch is a Mongrel that slips at 3000 and locks at 3100
According to the engine builder that setup should be running about 12-12.3 peak HP occurring in the range of 5700-5900 RPM's (at the drive shaft) and a peak torque of about 13-13.6 Ft/LBS occurring in the range of 4200-4500 RPM's (at the drive shaft). The builder also said that I should be able to turn this setup to 6100-6200 RPM's no problem
On the longest straight of my track (about 700 feet) I see a max of a little over 5500 RPM's so I am losing top end speed. I know others at my track are getting near the 6k RPM with this setup.
So my question is (I know finally), how do I get my RPM's up?
