I have done a bit of Googling and it apears that 1530 BHP per ton is needed to give an F1 car an initial 1 g accel before drag rears its head.
Always assuming you are happy to accept that there is some merit in considering BHP per ton as one way of visualising what makes things accelerate these F1 numbers enable us to consider your mate on the brakes.
If your man has 33000 LB of thrust and a T/W of say 0.8, you could reasonably say he is about to charge down the runway with the equivalent power of 25 F1 motor cars.
The 'about to' is for all the reasons that have been made clear earlier.
If his thrust weight ratio is 1 then the 25 becomes 31.
This is based on an F1 car having 900 BHP.
Should you want to use some other car then divide 900 by the BHP of your other car and multiply the 25 or 31 by this number.
Any help?
