They look real nice :icon_tup:

I made a similar thing out of the stock unit and in reality on the street in my own experience they work crap :icon_tdown:

Problem is most of the air speed is lost down the secondary runners in the lower inlet manifold, and cause you are running primary injectors at low speed low throttle the fuel mixing is rubbish :o10: everything suffers and its a basic mismatched concept that can never have the bugs tuned out as its a mechanical air flow and speed problem.

Once you are up and driving they are great :driving: I went back to a standard offset slightly staged primary to secondary butterfly system and all problems went away. A single large throttle or locked std triple butterfly especially one that interlinks primary and secondary lower runners will never be right......... not a warning against the group buy but worth knowing if your not aware of the issues of this type of thing and expect your car to be perfect in the way it runs.

Well it works great on my friend's drag car! I'm going to use one of the it on my street 20B FC. I'm excited!!!

That's why I asking if they would do a double plate if they had to design a new streeet version to include cruise control anyhow. My CBR 1000 has a similar double butterfly. The main throttle is closed at low speeds and only the little plates open giving about 20% of air volume. Above a certain rpm the main plates open up as well. I removed the little flap doors and deviders to enlarge the intake. For the most part when I had it tuned, they compensated for it. I'm not sure if it would be the same for this setup or not. Maybe it could be tuned and smoothed out with the PFC?

can we still jump on this gb?

any updates?

I have a new one that i bought for my 20B...they are the same throttle body. $325 shipped

[QUOTE=scrubolio;128762]any reviews on this TB?


Well my friend Poncho made 992rwhp at 47psi using this TB with a stock FD intake manifold running a semi-port.

My 20b FC make 715rwhp at 25 psi with the Rotary Works tb, planning on hitting 800rwhp next weekend than race at an import event on the following Sunday.

Anyone experiencing leaks due to the TB?
