Why are there no 8s?? Why is it I see no LS1s running 8s? There are several LS1s running ALL MOTOR in the high 9's and low 10s...it seems as though a measly shot of NOS and we'd see some 8's. For example: Colonel ran a 9.95 NA. Would I be wrong to assume that a mild 150 shot wouldn't net some 8s?
Re: Why are there no 8s?? Two words: Diminishing returns. The faster you are, the harder each tenth is to come by. I bet a 150 shot on the Colonels car might only take off 3-5 tenths. (No offense to you, Mr. Colonel, but I just don't see it being that easy.) Now, a 250 shot <img src="images/icons/shocked.gif" border="0"> ? Hmmmmmm.... <img src="images/icons/grin.gif" border="0">

Re: Why are there no 8s?? it is hard to go from a 11 sec pass to a 10 sec pass with a 150 shot, it can be done and several have done it, it has also been done from 10 sec to 9s , again this is even harder, i think it will take at least a 200 shot(if not more) to go from a 9.90 an 8.99 , my car(3rd gen T.P.I.) ran a 10.70 NA at 2700 ft, it took a 225 shot to go 9.50 at the same track, i am pretty sure it would have taken me at least a second stage of 125 hp more to run 8s,maybe more,
It would be cool to see someone attempt this (8s) that is- any takers??

Re: Why are there no 8s?? Interesting, I never really thought about "diminishing returns." Why is that? Wind Drag maybe?
I'm sure Colonels motor could handle a 200 shot, hell, maybe even a 300 shot. Any coments, Colonel? Its quite nobel of you to stay all motor, but 8s NA are a long, long, way a way. Any reason you haven't thought about 8s with the bottle? No offense, BTW. <img src="images/icons/smile.gif" border="0">

Re: Why are there no 8s?? I wanted first and foremost to go NA 9s. Now that I have that behind me I am indeed thinking about 8s on the bottle. It will take more than strapping a 150 shot to the car, however.
Here is my plan...
A return to 3.73 gears.
MAJOR fuel system reworking.
A MUCH tighter TQ converter.
A direct port 225-250 hp N2O kit.
That should do it. <img src="images/icons/smile.gif" border="0">
Diminishing returns...
Fighting inertia is not a linear thing and neither is fighting wind resistance. These things are exponential. The force of wind at 30 mph is only 1/4 that of wind at 60 mph and only 1/16 of that at 120 mph. Add that to the fact that an object takes 4 times as much power to move a certain distance in a vacuum in a given amount of time as it would to do it in half that time. And of course we're not just talking about the accelerating of the car but of all of it's moving components as well.
DISCLAIMER!!! I am no physicists so if any of these ideas are off, by all means feel free to correct me!
No offense taken. Quite the opposite. I'm flattered ya'll are considering me for the job! <img src="images/icons/wink.gif" border="0">

Re: Why are there no 8s?? I think it will be very hard due to the rear suspension (torque arm) of the Fbody vs a GN or a Mustang. There are already a good number of LT1s with enough mph, but they aren't getting the ET.
Of course there are stock rear suspension C4s in the 8s, it'll just take a LOT of top and midrange pull or a switch to like ladder bars or something.

Re: Why are there no 8s?? Nitrous makes a inefficent engine more efficent. So a stock engine will respond better to nitrous then say the Colonels engine. This is to say that engines like the colonels are already much more efficent then any stocker, thus you would need a large amount of spray to have the same effect.

On a percentage basis, yes, the inefficient engine will gain more from a given shot. But on an actual number basis the efficient engine will gain more due to it's ability to get the air in and especially out of the engine easier.
So, with a stock engine a true 100 shot might only give 90 hp at the crank where as my engine might get 110 hp. I'm not quoting actual numbers, just illustrating the idea. Not only does this engine have a higher VE but it also has more CIs. Larger CI engines can better utilize large amounts of N2O. There's only so much you can shove into a small cylinder.

hey nick a: dude wants to run 8's, lets go ahead and do that.. i'll call tnt and see if they want to sponsor an 8 second pass. <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />

As others have said, it's a lot harder to drop a second when you're going 9s than it is when you're going 12s. Not to mention that to run really good NA, you usually go with a very different cam vs. what a dedicated nitrous motor would use. That can make a big difference.
I'm not saying it won't happen soon. But it will take a lot more effort than simply strapping a shot of juice onto a quick NA car.

Re: Why are there no 8s?? I agree with crazy quick. The 4 th Gen fbods torque arm seems to be holding the quicker cars back. I know you said ls1's , but as far as the basic car goes, suspension is of course the same. The top guys all have 8 second power, but cant seem to hit the 8's yet(Top lt1 cars). If you look at any other stock suspesion cars, they do it routinely. Stock suspended Mustangs and G- dies do it quite frequently. I think the torque arm arm cars will get there. Maybe soon, but it will probably take even more power or some kind of torque arm improvement or chasis tunning.
4th gen fbods hower have had the power and mph for years now. And considering some of the owners are chassis shops or perfomance shops, they often know what they are doing, and how to put down power, so i often wonder if the torque arm is the problem.
.... As far as the adding a shot to the Colonels car, it's more of an extreme example, but think about a 6.90 pro stock car. If you add a 200 shot, it's not going to run 4.90
