" 335i's aren't the best drag car so that's a good thing. 18-20 psi would be a fun ride with an efficient setup on pump gas, no quarrel there. Anyway it's trivial because if you do want more it's not like you're forever locked into having no options. I've always thought it better to have goals in lap time, et, hp, etc than psi though. "
