Hi Frits, thanx for your response. I race a Suzuki RGV 250 at Lake Gairdner in South Australia. So far my best speed has been 140 MPH (225 KPH) average over a flying mile on 98 octane gasoline.
The last 2 years I have changed to the Fuel class and have run Methanol with limited success. Im going to change to E85 for next year. The reason for my question is that im trying to design some heads to run E85 on. I used some modified RGV SP heads to run the Methanol but the compression was too much so it wouldnt rev as much as I would have liked. I used some heads that Lozza designed for me to run on gasoline, they worked fine but I have reached the maximum output of those as they are distorting and the O ring shows signs of blowing out. I like to do as much as I can, as cheaply as I can so want to modify the heads that I used for Methanol to run on E85.
A friend has a set of Jolly Moto pipes and was good enough to measure them for me so I put the measurements into MOTA and made a few adjustments to them so they give a bit better top at the expense of mid range and made a set for myself.
Im going to work on the aerodynamics of the bike as well for next year, my goal is 150 MPH (250KPH)
Thanx again Dave[Vous devez être inscrit et connecté pour voir ce lien]
