If you are considering fitting a nitrous oxide system to your engine you really should read this first.

Interesting website Dave.

I occasionally have a weak moment and think about fitting a small plate system (75- 150 extra hp), but it ultimately seems like a lot of hassle, and pushes the car more towards a racecar setup and away from being a proper street driver. I get the impression that even with some knowledge and skill (and I have neither), sooner or later you're looking at burned pistons. Plus it adds to the complexity of the car. If you have a misfire up the track, is it carb related, ignition, nitrous pipework, nitrous wiring, solenoids, fuel pressure, etc, etc? I find it difficult enough to trace problems with a straightforward set- up.

Having said that, if I ever get tired of being whupped by that big red R/T....... :twisted:

Get that carb tuned and with your new pinion snubber and sticky tyres you will not be far behind me at all mate. :wink:

I am sure of it.

The good thing about NOS is it means you can have a streetable car but run decent times on the strip. How well it works and how much damage it can do depends very much on how you use it and how much you use. A small squirt in second and third gears will not be as much as of a shock as a big load right off the line.

I have to admit to thinking about using it at some point in the future. But then I look at the car and think "Do I really want to make this car any faster?"
The answer to that is NO!
This is not a race car. It is a fast street car. It has no roll bar or cage. It has standard seats and belts. It is all steel and will stay that way.

I also do not see the point of only having power part time. I want the power there all the time! :twisted:

I love it when you say that :twisted:

It raises an interesting point- all the other mods you'd have to make to your car to cope with a healthy dose of whiff. I note most of the kits sold to the hot hatch market don't exceed 75hp jets. I guess the engines/ chassis/ drivetrains wouldn't take much more in stock form.

How much quicker do you think one of our cars would run with, say, a 150hp plate system? If you're already running mid- 12's/ high 11's, the drivetrain's going to take a right pounding with an extra 150hp to absorb. I like to try and drive mine home after a day's racing, so then you're faced with getting the weight down to take some of the strain off the drivetrain, or fitting aftermarket half- shafts etc (or both). It's a slippery slope...

I still might do it one day though :wink:

Use the horsepower and ET calculations on my math spreadsheet to see how much the times for your car will improve.

A lot of the "Hot Hatch" lot are blowing their engines up. These cars make their power because the parts are light and will not take a lot more power than stock. Our american cars will take more abuse.

Going lean on fuel is the worst thing as will melt valves/pistons real quick.

You and your Maths Spreadsheet are a bad influence, Dave. :lol:

I plugged in an extra 150hp just to see what it does to the ET. Way quicker than I want to go :shock:

.

In a few years, when I'm sure I've got the car optimised with it's current set- up, I might think about a 75/ 100 shot system. Or if a 500hp fogger comes up at the right price..... :wink:
