I'm still the only cyborg owner with meth injection. I also did those numbers in Jan or Dec or Feb, not In the fall.
The cyborg def is what it is. Its always going to be a challenge to makes high end power and low end power with a 1.6L. If you need 300whp on pump gas or even 250whp on straight up 93oct, a turbo with a little more lag, double the price, and some bragging rights is prob a better option.
If your willing to run some E40/E50 mixes and Meth injection, then 270whp should be very obtainable with a good tuner. I had a ton of 275whp area V-dynos, and a couple with more then 280whp. But if your not putting the car on a scale instead of guessing, and not willing to run Meth/Eth mixes, then figure about 240-255whp tops on pump gas. Because its natural struggle to move air past the turbine, when the weather drops, its really wakes up. 233whp on the dyno jet, and 235whp on the V-dyno and the car went 13.3 on crappy cheap tires (then broke an axle ). On a 270whp tune on slicks that's a 12sec all day, all night. If you need more, def plenty of other options, but I'd suggest just buying a focus or srt4 or mazdaspeed3 if your really just that focused on drag strip only times.
