Nitrous and .90 racing

[Chris Williams]

Not sure why you'd want to... To run T/D, T/S, OK, but not sure why you'd want that much complexity when a simple normally aspirated car with anything more than 750 hp can run the .90 number respectably.

The key in .90 is consistency/predictability, the more exotic/complex you go, the farther you go from that, IMHO.

Mike, you wanna be able to dump and half the balls to be able to take the stripe? Seems like the only reason to have it.

used to be legal in ihra, i remember a yellow chevelle running 10.90 at 170. and n.o.s. was paying contingency. like it or not? i didn't really care, but would of had a system on the car myself.

You mean NOS is not legal ? oops

Bryan,
I thought your air bottle looked a little funny....was wondering why it was blue and you kept putting a torch to it...haha!

I have wished I had it a couple times. At some tracks where track prep is poor, cough cough, Indy, cough cough, my car will sometimes launch left or right a good amount. If this happens, I can almost guarantee it's going to slow me down about .02. I have wished I had it to catch up. After this happens and I'm sittin there on the stop, I wonder if I should just turn the delay box off, thus opening the stop, and taking off to catch up. But it's always by the time I make a decision, I'm already off the stop and on my way. Usually not with a good outcome.

I have wondered about this rule too. About 22 years ago I asked an NHRA official and was told that they didn't want it used to make big top-end speeds to take the stripe (this was in the era that S/G cars were running around 133 mph). Many of us had mid-low 9 second cars with a throttle stop coming on in 2nd gear, so we had an override button with as much acceleration as most N2O systems. I remember helping a big-name S/G racer from the area when he broke a trans and needed to change it between rounds, and I saw the hidden N2O system in his car (solenoids were hidden in the lower A-pillar area, tubes apparently ran into the intake through a larger hose disguised as a vacuum hose). I looked at him and laughed, never said another word about it.

In the Alston Super Series (which included standard .90 classes as well as 7.90, 11.90 & 12.90), there was no prohibition on it in the non-NHRA .90 classes (I checked specifically). There were a few users, such as doorslammers running 7.90 class. I put a system on my 11.90 car for a race at a non-factored track that was known for very high corrected altitude readings. The car would barely run 11.90 at that track, and I planned to use it if the air got too bad. I did use it one pass in the worst part of the day, and it looked like I was on my way to a loss (car would have run a 12.00 or so), but I gave it a tiny shot and took the stripe. A couple of guys went to the tower and tried to protest (I had previously cleared it with both the division director and the track).
