The Ebay is another option - that one looks better, but I'd like to find the company website that makes it...
Also I'm still working on finding out if the one Shawn Church dyno'd is in production. At least we know that one has been tested. The theory might be the same for all but design nuances like angle of the rifling/vanes (whatever you want to call it), the depth/length, might contribute to one being a better choice than the other?

I carefully tested one myself on the Z and it did nothing up or down.
I can't comment on what Shawns results were, he told me the same thing. And Shawn is credible... so I seriously looked into it. I just didn't see any effect in my testing... and if I saw even 1 verifyable HP, I would have researched this subject very heavily.
But I won't say no just yet. If any one wants a free pre/post dyno of their TB spacer just let me know.

tb spacers do create horsepower. im not sure about 8 hp but if indeed it is ''rifled'' then yes, i could see that benefitting the vq. all that air has to hit that 60 degree bend right after the tbi and if the rifling helps the air to take that bend quciker and not back up the incoming air behind it then it should add hp. once again not much, but noticeable. its like the few turbo cars ive tuned, when we removed some of the intake piping that had bends and curves and swapped them for straighter pipes it made more hp.

I stopped by Shawn's place today... and have made contact with the manufacturer... I hope to be testing the one Shawn has soon. Tony has graciously offered his time and equipment for testing and DaveO is interested in testing... if the results are the same as Shawn saw (or even a decent fraction of it) this could be worthwhile... Time will tell.

Keep us updated! Let us know what the outcome is! If it works...two words "Group buy"!

TB spacer
I ordered one off of e-bay...
Now the million dollar question is.... which way/direction do you install the rifle bore to supposedly help with directing airflow?
I'm going to get a new Z-tube and cut it back a bit so that there are no crimps. I'll also probably get rid of the crinkle rubber tube that connects the z-tube to the MAF and replace it with something smooth... I know smooth tubes were worth over 10hp on my Viper GTS... if I could get 1-2hp or even better throttle response, it would be worth it..
