If your getting a dart i assume your like any of us, YOUR going to go allll out, so it can hold around 2k horepower, half of that is 1k (my goal) and when you got that much POwer i dont know how much 80 pounds will do on your et.
But i also would have liked the aluminum one, i was thinking of polishing it but my engine builder made fun of me so i ended up with the iron 165 pounder. I hope you get the aluminum one. Peace
