I agree the supercharged alcohol dragsters are much less powerful than the nitromethane cocktail supercharged dragsters. But what I am referring to is a direct-injection, methanol fueled, turbocharged 700cu inch application running upwards of 60 psi boost. Very feasable, and more powerful than nitro
Methanol has the fastest burn rate and much higher latent heat of vaporization. Nitromethane is limited due it's inconsitancy and, despite popular belief, very slow flame kernel burn rates. Yes, nitro burns very slow at all cyl pressures, so slow that it still burns long after exhaust valve opens as you can see by the yellow flames blasting out the runners. Nitromethane runs stoichiometric at close to 1 to 1 so top fuelers are running on verge of hydrolock. But an entire run, including burnout, there will be less than 1200 ignition events so net fuel volume is not an issue. Dont get me wrong, I full heartedly believe the nitro burners are the kings of drag racing, the most spectacular to watch of any racing for that matter, however - it's old technology (except for ecu). Direct Injection methanol ICE for a top fuel has much more potential than nitro. Probably wont be implemented either because 8000+ HP is rarely fully harnessed, and at the end of the day the yellow flames and nitro fumes are more addictive than HP$
