Found it!! Just trying to figure out where to tap for the nitrous spray.

I drilled and tapped my plenum for future Meth... one on each side...

Thanks TT...so the idea of putting NOS after the IAT is....crap.

In theory and in our case, practicality. An old trick on the new fuel injected bikes is to spray it into the air box, where the IAT sensor is, utlimately enrichening...

IDU...as a teacher once told me a lot...I don't understand. IAT is in the intake (after the MAF/intercoolers) or before the MAF?

[ttboost]

I think our IAT is in the plenum, which is after IC's and WAY after MAFs.

OK here goes...Air comes into (or gets sucked into) airbox though vents in front on top of radiator bracket, through MAFs, down piping into turbo compressor inlet, gets compressed and pushed through piping into IC's, then pushed into more piping up into "Y" pipe into plenum, where I think said IAT sensor is, down into the cylinders to mix with...well you get it from there....

Suck, bang, blow, go....got it....I've read it is best to spray NOS after the IAT, but apparently we can't do that so I guess it's before the intake pressure (x2) sensor or after. On the road so I'll have to check when I get home.

The IAT sensor is just upstream of the throttle body in the intake manifold. Tap your bi-pipes feeding into TB. See Kevin's old posts from last year when he pulled his engine... I remember he had a good pic. I'm too lazy to search tonight. sorry :)
