Its the pickup thats different, the CT9 comes on boost far quicker, whereas the TD04 being a bigger turbo, takes longer. If you can change gear quick enough to keep the revs high yeah I could see it being close. Good thing with the CT9 is you dont need to rev it that high. As with the TD04 you do to make the most of the boost. Be interesting to see a CT9 against TD04 with similar supporting mods against each other. D
