There is some good, and not so good, Info in this thread. But the basis of this thread is to say the motorsport nozzle will not work and will cause damage to the late(non reintrant) bowl. This could not be further from the truth. I can see why it got so far on CF because thats what always happens over there. But I cant believe it here.
I have probably 20-30 sets of these of all sizes in the field as we speak, including in everything I own. I have three trucks. Each one has a different bowl design, reintrant, non reintrant, and a custom bowl that we designed. All three engines are running motorsport nozzles. Two are 100hp, and one is 200% over. I have put about 50k miles on the non reintrant at 600+ hp towing 18k, about 20k miles on the reintrant. We have about 150 passes on the custom bowl at 1200-1300 hp, and about 40 passes at 1400+hp. Out of the 20-30 sets I have in the field, along with my three, guess how many piston failures? ZERO. I am pretty confident that we have one of the two biggest hp CR's in drag racing, and never have had a piston failure. Torrey(the other one of the two mentioned) has not had any either with this nozzle as far as I know. We can go over theories all day, but Im telling what works in real world applocations. So all the guys that are freaked out about the guy on CF melting down with motorsport nozzles, get over it. Its another melted late 5.9. There were thousands before that one and will be thousands after. IT HAS NOTHING TO DO WITH HIS NOZZLE. If the motorsport nozzle was the cause of the damage, dont you think we would have seen a failure by now? And as far as power, they are great. If someone thinks there is a better option for power, I challenge you to prove it. There will be people say that something else will make more power, but I bet you no one sends a set to compare.
