Indeed. Wheras an F1 engine of half the capacity redlines at around18500 RPM and lasts more than 5 seconds...
But thse are not adapted stock engines, they are designed to do the job...
If you look at the specs you have posted, it becomes totally obvious that to get more power, given that these engines are being pumped so full of steroids thay can't deliver any more torque, what is needed is a higher revving engine.
Frm memory a drag engine peaks out around 5000 bhp? On ewhat 7 liters plus super charging?
Turbocharged 1.5 liter F1 engines achieved over 1000 bhp and NO NITRO.. That suggests that with correct design and no nitro at all, 5000 bhp on a blown 5 liter engine should be possible, albeit at somewhere in the16-18k RPM mark.
No, its true. Top fuel engines are very crude. Development has gone eniterly in the direction of upping torque, rather than allowing them to rev more freely. For a given torque, power goes up as the square of RPM. Now I won;t claim that 19k RPM on that sioze of engine is possible, but certailny at least 50% more RPM should be available, giving double the Bhp for teh same peak cylinder pressures.
Couple an engine like that to a hi tech gearbox and traction control, and you would have a drag car that would simply wipe the floor with anything existing.
