nitrous tuning 1jz

[thechuckster]

can you get a coloured gas to go thru the system and then manually trigger the soleniod?

[Jasper]

Trigger it with the engine stopped. (not the fuel solenoid though)

[chris davey]

Wouldn't it then pool in the manifold and when I crank it it could backfire?

I was told to do the static test which is nuetral to 3000rpm, activate it and if it goes to redline it could be a little lean, if it bogs a bit it is rich. (I have wideband and datalogging anyway) Advised that it can't do any damage to engine at such low TPS setting.

[Jasper]

It wouldn't get into the manifold, because the throttle would be shut. The nitrous would slowly dissipate out of the air filter. I wouldn't go starting the engine straight away afterwards...
