89 Hatch, stock bottom end (oil pan has never been off), Twisted Wedge heads, custom cam, C4 with brake, 4.10 gear. My Son and I just finished the car in June. Built it to run mid 12s, but with some suspension tweaking and putting the car on a diet, we have run a best of 11.85 @ 111mph with a 1.53 60’. We feel we’ve squeezed everything we can get out of the 170k 302. We are planning on adding nitrous, but have no experience with it. Plans are for a wet kit, progressive controller, adjustable timing retard module (we have a MSD 6AL, MSD billet dist). My Son already ordered the Edelbrock nitrous kit, question is what controller should we use? What timing retard to use? We were thinking a micro switch on the throttle, wired to a relay so the nitrous/progressive controller only activates when the transbrake is release? Looking for advise.
