oldcorollas Forums Junkie Location: Kita-Ku, Sapporo, Japan Registered: January 2003	Re: Differences between the Group A and Formula Atlantic engines Fri, 16 September 2005 06:34 Dorio86 wrote on Fri, 16 September 2005 16:07 Any other words you want to put in my mouth? fairy nuff how about "i emailed Hasselgren about formula atlantic engine specs and they said......" the way they make it is rpm. there is a physical limit on how much torque an engine can produce... the limit of torque that can be made depends on rpm also, because higher rpm allows more effective use of intake tuning (since the sound waves get stronger.. sorta)... so alhtough a road going engine may only make 100Nm/L, a race going high rpm engine may make 130Nm/L and due to the formula of calculating power, higher rpm makes a significant difference ie, 8000 to 12000rpm (with same torque) immediately means 50% more power! Cya, Stewart ps, equation is power = (torque x rpm) / 9502 where power is in kW and torque is in Nm. [Updated on: Fri, 16 September 2005 06:36] [Report message to a moderator]
