Sadly, SP Racer stated a little more reality than what I've gone thru. Though I did one good session with it, now I'm beginning to wonder if X12 would last a 30mins to 45 mins race + qualifying sessions.
PMT, can those guys you mentioned make the engine last without stalling? Perhaps there is some hope? Ill give X12 another chance after breaking in my new Nova engine.
How can one make and sell a engine like that????
