how is the fi guys keeping gaskets in place?with an o-ringed block & heads i figured cylinder pressure on the nitrous mill would be more but given the same hp at same rpms i thought it would last as long.

However I agree with you that the N2O LS1 cars are quite a bit behind the turbo cars, for the time being.
I definately want to see some nitrous cars kick the crap out of the FI cars, but I think it will be a while simply because it is probably going to take the same amount of money (if not more) as going with FI. I don't think many people would spend that kind of money on a nitrous car when they can go with FI and be in the top group of cars.
On a side not, too bad a standard SBC doesn't count,haha. There is a local racer that runs 4.7x's in the the 1/8 with a SBC that is less than 380ci's that is in a camaro. It has 3 stages of NX spray bars in the intake. It is one of the most violently launching cars I have ever seen, fun to watch haha.

Ok, I agree I should not have included a BBC reference in my first post, so I'll revise it: Ain't no way that a N2O LS1 motor can compete with turbo LS1-type motor cars and they might not be able to compete with supercharged cars either. For example, I can't a N2O motor matching the power made by W2W's turbo car. JMHO.
BTW, I thought the fastest Pro Mod cars were blown hemi motored cars?

i'm in the process of building a nitrous car and intend to be "fast" but i am starting to think that the nitrous guys, myself included are just not going to be able to hang with the FI guys...(why i'm thinking of buying a turbo instead of a second stage)....but who knows....

right now with no weight break i don't see why a " purpose" built nitrous mill can't keep up with the fi cars but when mid 7s start being common it would be very hard to keep up.lets go nitrous junkies,someone with the funds build a motor that can handle a staged 800 shot.

Personnally, I don't foresee a LS1 N2O car running a 7.xx anytime soon. I discussed this with Kurt at W2W, who said the heads just want hold the cylinder pressure. On the other hand, he said that he can make over 1300 reliable hp with his turbo LS1 type motor. I've got a N2O setup on both my street and race car and basically a N2O guy at heart.
