Casper's original set of PPE twins worked very well, especially over 4000rpm. They launched violently, and carried big power past 5200rpm. Exceptional RPM range. We have detuned the Bonneville set since we won't be using that high of RPM.
We stopped running them so PPE could tool up the retail kit, and HP was not the problem we encountered at El Mirage. If anything, we needed less HP because El Mirage has about as much traction as sand this year.
When we get back from Bonneville, Casper is going back to 4x4 and the dragstrip. Perhaps some AutoX racing or Desert racing will be in the future.
The engine displacement break for LSR racing occurs at 440ci, so we punched it out to 441.5ci to run A/DT class. If we get time, we will run B/DT as well by swapping in a lightly mod'd stock displacement engine.
