Once again another person that thinks you have to choke a motor with fuel on the dyno to make it spool. N2O doesn't seem to do any good below 18 psi unless you have a controller to ramp it up.
it was a big hp dyno competition. the turbo on the truck came out of a twin setup and was trying to be used as a big single. the turbo was hard to spool and nitrous was used to try to get up to 20psi before really laying off into it.
