Modified Elan Dyno Data
Posted: Thu Oct 20, 2005 2:00 pm
I have posted in the photo gallery section in the "Rohans Elans" folder a word document with details of the various developed engines I have built over the years and the dyno results for these engines compared with a standard big valve twin cam.
The latest engine I have just finished and dynoed is "engine 3" a nominal 170hp spec 1600cc twin cam. It produced a very tractable 98kw / 131hp at the back wheels an estimated engine output of 171hp at 7000 rpm with more power and torque than a standard sprint engine across the total rev band. A road compression ratio version of this engine would produce around 165hp and be totally street tractable.
The rear wheel output is the same as the dyno measures on the properly setup , throttle body injection 20 valve 1600cc Toyota 4AGE engines at similar rpm that they put in their Elfin clubmans ( a Lotus 7 clone). Not bad for 40 year old engine design. Elfin have just started building their latest clubman, a 6 litre Gen 111 GM V8 in a clubman style body !! A power to weight ratio that puts just about anything less than a F1 car to shame.
