he meant forced induction and headers i.e. gtm supercharger plus longtubes. these might be a worthwhile mod for that purpose next guy getting sam to install a kit with headers should grab these and have them done at the same time, that why the guys at gtm could do the experimenting faster and everyone with a kit would know what to set them to so it only has to be done once.

It has been done, I tested it for GTM.
I ended up a few HP less on the top end, same as when I was NA with bolt ons, but also saw better HP/TQ throughout the power band. Also, my car was running in 100° weather.

I think 1slow370 meant supercharger, LTH and cam gears. And Mike@GTM also commented about higher power gains on a GTM supercharger kit on a non-VVEL VQ engine because they have full control on the cams and overlap;http://www.the370z.com/forced-induct...tml#post963062

yeah dreamer go get some longtubes and the cam gears and go back to sam

Eh, I want to see some NA results first before I jump on this.
I will see if Sam has any info on these and if he is willing to do some internal testing.
