Thanks for all the replies, hopefully I'm in the high twenties then. With the TSR evo pipe it certainly has no trouble pulling the 4.8 gearing I've got it set up on at the moment!

So what gearing are you using to get to 85mph.?
I ask because I am almost finished building the same with an LTH Reed manifold and intend to go 4.9

Wow, thanks Darrell that's great. I presume that your drag coefficient for the graph would have been calculated with the rider prone?

yes was sprint conditions the data was pulled from on a level runway and includes other companys dyno graphs and sprint/top speed results too so the inputs for the softwares calculations are real world so not just a keyboard/pc simulation.
