I think if you built a h22 and turbo you would be far past 13's. Im guessing mid to low 12's stripped running high boost with slicks.

A h22 with a 55 shot would put you close to high 13's with slicks, i/h/e and tuneing.

And nitrous would be your best bet as you wont have to run it all the time so you can feel "safe" as you said above.
