Finalizing my nitrous setup

Fuel pressure is critical as manufacture should have safe number to use. C16 for fuel.Converter becomes about 1000 rpms looser if it is a N/A converter yet gained the 1.1 seconds. Dont run motor cold as it will sneeze out the carb. Butterflies dont like that.

Thanks for the responses, I forgot to mention that I have a separate regulator for the shot of fuel and I'm told 6PSI is a good location. I have also hear about the cold plugs and possibly a MSD cap-a-dapt to prevent misfires with the rotor phasing. Will definitely get colder plugs. We will see what happens opening day.

The large distributor cap is needed. I split the difference on phasing from the 2 different timing settings. 6psi is safe. When everything is happy you can get down to 5psi. You should monitor fuel psi or set with a flow tool. Flow tool is nothing more then a 73 jet and pressure gauge. Set regulator from the tool. If it's not watched or set and you dont have enough fuel pump it will go clean and be fast for about 2 seconds and then lots of smoke. It does help. I'm sure your plate has been flowed and jet sizes determined. Mine is pretty aggressive with 8 sizes bigger on nitrous over gas jet

I have the larger dist. cap on the way. I have a very stout Product Engineering fuel pump so I don't think fuel pressure will be an issue after I test it. Thanks for all of the info!
