Just for info ~
If you’ve read the power & torque feature on the main Seatcupra.net page you’ll appreciate that acceleration is dependant on the torque arriving at the wheels.
I had to try out the new Anorak I got for Christmas anyway…..so I made some rough calculations based on gearing ratios and figures quoted by Upsolute for a 110Tdi upgrade (using their published figures of 143bhp and 215lbs.ft torqe, which are if anything conservative).
Comparing remapped TDI and 20VT in top gear (5th for TDI, 6th obviously for 20VT) the TDI develops approx 8.5% more torque at the wheels (and therefore8.5% stronger acceleration) at 55mph.
This advantage is reduced to nothing by 85mph (where each car will be accelerating at the same rate), and the 20VT pulls harder from this point onwards ~ providing approx 9% more torque at the wheels by 120mph.
Not the full picture by any means, but interesting nonetheless. My summary of this would be that in “real world” motoring there wouldn’t be anything in it. Over 90mph the 20VT would be stronger by a noticable amount….but I (personally) don’t do much of my motoring above this speed (ossifer).
Not bad considering the economy/insurance/tax advantages…
Before they spot this and tell me….a similarly remapped 20VT would (of course) eat you for breakfast.
Mind you......you can Upsolute a euro TDI 150 to 182bhp and 312lbs.ft. ;)
