Thanks all for the input, it is always much appreciated.
I have done some spreadsheet runs on your site Sum, and had neglected to thank you, they threw up some interesting stuff.
We haven't been on the dyno this year, time and coin poor we are just running with what we have. Sadly we dont have the time or resources to get the Haltech ECU sorted which would allow us to rev the combo a little harder.
The spreadsheet , with conservative estimates on frontal area suggested we needed 312hp to reach 215mph. The Colonel is confident that with a few changes that have been made since and the full exhaust that we are possibly 40 or 50 hp above that.
No we don't have mile by mile times but we were almost top speeding by the end of the three, and this was leaving the push car in third gear at 35mph and shifting at 150. If we used first and second gear we will accelerate faster even if we step down two gears.
The bottom line is the car has until this point had full traction, we haven't hit the "aero wall" yet. Fairings on the axles and a clean up of bodywork will offer up free horsepower.
So many unknowns, we figured we'll just put the 2.14 in, it will probably go slower, then we have our answer, we can fit the 2.28 at the lake .....if that goes slower then the only option for us is to rev the ring out of the 232, we've had advice that there are diminishing gains there.
So far we've been lucky.
