Ok as promised here is the DYNO from the test of the newly installed SMOOTHBOOST on my car. First off, AMP slightly detuned the car down to about 744 HP from the high of about 780 HP on the last dyno. The BOOST level on THAT dyno was around 14.5 PSI.

The main reason for the slight detune that is the duty cycle of the INJECTOR was over 90% at that 14.5P PSI level. Remember that I am running E85 here also. SO NOW the Duty cycle of the stock LT4 injector is around the 86% level at around 13 PSI of boost.

So there are as mentioned in last post, 10 different detents on a rotary switch that I have now in my console. The RED line on the DYNO chart indicates the power level at BOTH the DETENT 9 and 10 Positions (full boost).

Blue line is DETENT position 8 on the switch which results in about 30 LESS HP.

Green line is DETENT position 7 on the switch or about 100HP less than what you get with FULL BOOST.

Yellow line is Detent position 6 on switch or about 200HP less than full boost.

The other detents are inactive currently on the switch. I will say that the throttle response is MUCH MUCH smoother with the SMOOTHBOOST than with the stock Vacuum set up. I have a fairly large cam so I believe at times that would affect the responsiveness of the supercharger. In effect the feeling was to me that the throttle was a little jumpy with the stock set up.

You CAN actually change the boost setting on the fly while the car is moving. It kind of felt like an old school NITROUS kick when I changed from Detent 6 for instance to Detent 10 (full boost).

I talking with SAM at AMP, he said once the car is tuned for FULL BOOST than any of the other setting DO NOT require any separate tuning.

Anyway, I know others have SMOOTHBOOST so perhaps they can chime in. LOL
