88mm slip in cylinders, big cam, high compression ratio, centermounted 40mm Dellorto, 009 distributor, some cheap header exhaust. Tuned by an old race guru.
You may push your luck too far if you tried 115. I don't think I will again, without some serious suspension mods and probably a roll cage. But hey, I was young and dumb :)
BTW I don't think the car could have done it twice. It was a short lived , high revving engine. And I beat the snot out of it :D
