If your using this on an M5, I'd start with a 50hp setting just to be on the safe side. You should be fine up to 100hp, but if you start stepping up beyond this ... take it slowly.
I believe most previous installations have gone direct port (8 individual nozzles) and this would be the ideal setup, plumbed directly into the velocity stacks. However, this becomes very intricate with running your lines, cutting holes etc. Perhaps just two nozzles in the intake tubes would be a good alternative. I use the ZEX kits.
Make sure you have a wideband o2 setup when you do your tests after installation, keep it rich and safe. Only activate nitrous at WOT and preferrably above 2,500rpm. Make sure not to hit the rev limiter while on the bottle!
I'm a distributor for ZEX, so I might be biased  . Enjoy! |
To be even more safe you can add a WOT switch (which will only actitvae the NOS at WOT) and a window switch (which will apply the NOS at a set RPM and end it at another ie. before the redline)
I use both of these saftey devices on my Cobra and run a 150hp wet shot with no problems.
