thanks for the responses guys..... i initially posted the question because I wanted to get a feel for what peoples experiences are with NOS.
My car is currently running 0.8 bar with dump and free flow exhaust. I've also got a SAFC. Normally the next logical step would be to install an FMIC but here is where i have the dilemma. I've seen cars with a similar setup with FMIC and they tend to run 13.7-13.9 quarters. If what Rev210 says is true then if I install NOS and get a 1s improvement then I'll be estatic!!
the last time i was at the drags (without aftermarket dumps and cat) the best i could muster was 14.1. If i can get low 13s then i'll be over the moon :uh-huh:
