Hey Mark, you going to be at vegas? I will, should be pushing 12 to 15 psi! See you there!!

My car ran 14:teens at it best on motor.

When you take timing out and put the good gas in it will slow down to about 15:0. On a 150 shot it has gone 12:0's a lot, and 12:00 twice.

When I went 12:001 at RT66 the car was running on ET Streets and through exhaust. I have used 2 different converters, but always 3.91 gears. Car weighed 3250# w/me in it.

I was at US41 one day running high 12's with the car on a 100 shot. A buddy was there with his car and broke. He drove my car the 85 mile trip home while I trailered his for him.

I used a really simple system. Top Gun plate and an electric fuel pump. The first year I sprayed I triggered the system with the horn button. After that I put the WOT switch on the carb.

I would actually launch the car with the nitrous on the horn button. I would hit the button just before I let off the brake and the car would really jump off the line. It would pull the left front about 4".

I did a lot of stuff to the car after that to try and get weight out, and make it more consistent. Unfortunately, a divorce, job loss, working too much overtime, and finally buying a home got in the way. Now that that is all over, I am going to try spraying one more time in my new car. I have a combination that I want to try that should put the Daytona deep into the 10's, and hopefully without killing parts.

One other caveat about spray, be very, very careful when the weather gets below 60*. For some reason that seems to be the magic number where the tune-up changes and goes way nitrous rich. Bad things tend to happen then.

Finally, boost is boost whether it comes from a bottle, turbo, or blower. Done right it is highly efficient and safe. Done wrong and it will break parts.

Nitrous is a lot of fun, but I think a turbo is easier on parts once you get it set up. However, if you follow the turbo guys you will see there is still a point where they start breaking parts, mainly taking out head gaskets and pistons, which is the same thing I have done.

Shaker223 has been really fast with a "stock" Slant, but he has a copper head gasket and o-ringed block and has still crossed the magic boundry. I'm still trying to find out what year Slant came "stock" with o-ringed blocks and copper head gaskets.

There are a couple other really, really fast turbo cars on here too, and they have both crossed the line also.

Drake's were incredibly fast with the Simca after they figured it out, but they also took out a couple pistons and head gaskets. By Tom's own admission they had a $10,000 fuel/boost management system on the car too.

There's a couple blower cars out there that have been pretty tough on head gaskets/pistons until they got it figured out too.

Remember, speed costs money, how fast you want to spend?

Thanks for that info. Pretty encouraging that you were able to launch with the nitrous activated. Speaks volumes about how tough these motors are.

I bet it was cool to have that much daylight under the wheel

I have WOT switchs on both my cars, and launch on the bottle

NO2 is an oxidizer which allows the engine to burn more fuel because it in essence increases the oxygen content of the intake charge. NO2 is not boost. Blowers and Turbos create boost (pressure greater than one atmosphere). The concept of increasing fuel is the same in each case because there is an increase in oxygen.

NA motors typically want around a 12.5:1 air fuel ratio for peak power. Turbo engines typically like 11.5:1 for peak power. (typically speaking because every engine is different) I don't know what the NO2 motors like in terms of an air fuel ratio.

The best tool you can get is a wide band O2 sensor. A recordable unit is best because there is a lot of stuff going on when you are going down the track. Keep the mufflers too.
