Has anyone had experience setting up Nitrous on engines running methanol???

I guess you would have to up the fuel jets.... Anyone got a Methanol / Nitrous jetting chart????

Thanks

I imagine this is a plate system?

I guess it is a fairly general question..... However, I do have a client that wants to run a direct port system on a BBC with Crower mechanical injection.....

I would appreciate any input....

Does he want to try and run everything on alcohol? Normally it works better if you keep one or the other on gas. The general rule we have always gone by is to maintain the same jetting but double the fuel pressure. This is assuming you would normally be running between 6-7psi. It has seemed to work well.

Yeah the whole system will be running on alcohol.....

I would recommend leaving the nitrous on gasoline if the engine is running on alcohol. When you run everything on alcohol things tend to be too cold which can lead to problems. By leaving the nitrous on gasoline you are able to keep some heat in the engine which helps with the mixture and atomization of the fuel as well as the ability for the ignition system to light it.

We have been running nitrous and alcohol on an injected bbc for a few years now with great success. We have a NX Shark fogger system for alcohol. There was a learning curve at first, like many bracket racers we ran the injector a little fat for consistency so we had to retune that. We also found the alcohol does not like a lot of timing retard, to keep heat in the combution chamber. For example, on a 500 hit we only take out 10 degrees. The plugs are also much harder to read compared to a gas tuneup. If someone is willing to take the time to learn it definetly works well.
