Since this thread was active I got married, went to the Bahamas for my honeymoon, celebrated Christmas and New Years! December was a super busy month for me.
The module is still waiting to be tested. I have someone interested in testing it, I just need to arrange with them to get it tested.

...sorry I know, back from the dead.
Was reading the viper vs supra thread in the street racing section where the supra was brake boosting and remembered how lots of people believe the Z has no lag whatsoever with turbos

i said... "the myth that SC's have less a Turbo is what it is.. a myth"
never once did i say turbo's have no lag... why the hell would i say that..

doug, I know you said that 50 times. I said 50 times you don't understand the meaning of the word lag
you're confusing lag with the amount of boost, which are different things
to make my point, you can take a SC car and stab at the throttle full on then full off real quick 10 times in a couple seconds and get instant reactive boost every time as fast as you can move your feet. If you try it with a turbo car, the turbos are going to try to spool, but probably not spool into positive amounts of boost. If they do, it's going to be a weird sensation of the car feeling drunk not really getting into boost when you stab the throttle.
And it's not going to be consistent between different rpms. If you wanted to use a high rpm example where the turbo is more responsive to quick stabs of the throttle, then it could be said at high rpms on a SC you're getting around 90-95% full boost instantly reactive to quick throttle stabs

yeah i know. still, comparing the vortech vs the single, like you said, rpms and gear selection are major factors, in a high gear with low rpms, the turbo is very slow to respond, whereas the sc reacts better, but in a low gear, at just about any rpm, the turbo wins everytime. i know you arent talking about numbers, but compare power curves, that directly relates to boost response.

The only problem with that Sentry is that you...we...may be getting 1 maybe 2 psi at 3000rpm and 2 -3 psi at 3500rpm and the TT has just went from 0 to 6-7-8-9psi from 3000 to 3800rpms . Our quicker onset of boost never really gives us any advantage at all .

I know, I'm not saying we have an advantage with boost at low rpms compared to turbos
Just saying there's no lag in response from our FI kit to start making whatever boost that's available at that rpm
Doug's whole theory that "SC's have less lag than turbos is a myth" is crap. I can cite a million sources and books that say otherwise. I WILL say though that with the 350Z's turbos, that statement is more true than say a supra. But the statement itself is not true
SC's have no need to brake boost, the response is instant. But at low rpms they're not going to produce as much boost as a turbo which is a disadvantage.

What's up with this brake boosting module that KP was talking about?

well your instant response doesn't really mean **** when at 3 PSI less than you i am making more power at ever RPM except after 6000
