Generally, it's not the first 1/2 second you are trying to shave off your 1/4mile time that is hard... its trying to shave off that last 1/10 of a second in the 1/4 mile that gets quite costly and not quite as rewarding.
Personally, if shaving 1/2 a second off my 1/4 mile time was important to me, I wouldn't care where I lost it.
I just think it takes more than 20 HP to lose a 1/2 a second in the 1/4. But it seems Needswings "single" intake still accomplishes it.
