Nitrous and .90 racing

GRIGGS · 09-24-2009, 04:49 PM

Just wondering how ya'll(that's a southern word to all my northern friends, except Lynn, she knows how to use it) feel about different power adders and running the .90 stuff. Just a little curious.

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

Come on Derek!!!! You know you want to say it.

Okay Mike I'll take the bait.

I can't understand why superchargers and turbochargers are allowed, but nitrous isn't?
They allow power-adders that the engine should be built to handle (drop in compression ratio, etc) at a cost of a couple thousand dollars at least, but a simple $500-600 nitrous system that could put an 11 second car into the tens and therefore possibly allow another competitor into the world of divisional and national racing is not allowed??

Spraying to take the stripe I can understand somewhat, but until you realize you may be getting into more trouble using it for that versus leaving it alone (assuming the car will get close to the 10.90 standard before adding the bottle), the argument doesn't hold much weight in my opinion. I've seen a few racers do it, and so far my record trying it is 1-3. I'd rather dial the car honest and do my job than second guess the finish line. Unless the traction is subjective, I leave the juice off when bracket racing.

Now granted I'm probably in the minority with a 3600 lb SBC street car, but for a $9K pump gas engine that runs 11.40-11.50 @ 115 mph in the heat, a little shot of the bottle would allow me to participate in the "entry level" pro-tree class (keep in mind NHRA used the term entry level meaning no double entry at nationals, no national championship, etc). I know people have a lot of time and money in their cars regardless of class, but I think more could participate.

Just an opinion from an "outsider" who'd like to race!

This may be closer to happening. Several divisions have now allowed N2O in diesels in the .90 classes. I know D4, D5 & D7 have had diesels race LODRS races with N2O. Here is video of one running this past weekend:

Your all missing the point... A blower or super charger, and a turbo charger can not be changed going down the track. You cannot change the boost or the pullys,

n2o is a chemical. It is also very explosive, do you want some jurk next to you with no brains with this stuff? I have been to the track and seen a intake explode, it hit joe deluca in the head...

If you want to go faster take some weight out OF your car, it takes some work so get off your fat lazy *** like most racers do..

To get more cars at the div. Races, nhra could change the rule on the weight..2800 lbs. Is so stupid. And you know that a heavy car is not as safe as a lite one on. ( i mean mass)

n2o just makes a soso driver look good, cant cut a lite just hit the bottle ...wow

we have no weight rule in the southeast 10.90 outlaw assn so come race with us
