Rocket42, I am not sure. I really like the 5 port turbo but may consider the 7 port turbo. To me it seems as if trucks already have excellent bottom end due to their ultra low gearing but I have just never seen a truggy pull down the straight with the top end of a buggy. I had a dynamite .28 in my previous crt and to my surprise the motor ran ok but it just didnt have the straightaway speed, fuel mileage is also a concern for me. I would have to hear some feedback on the .26 before I make up my mind.
