Ladies and Gents,

As a heads up...I'm working on developing a billet throttle body for my 2008 4.2 setup. I wanted to see if others had an interest something of this nature. I'm debating following through with getting a cast mold made to produce these samples as well as the 5.0 setup. Once I am able to sample some data, I will be able to verify if and what areas can be enhanced. If so, I will move forward with dyno data before and after to support it. I know boring the throttle is an option and seems that can go up to 80mm or so.

If someone has a spare 5.0 throttle I can gather dimensions from.. I can create a model and make this when I mill the 4.2.

I'm going to verify which models use the same throttle and support the most common first. I believe the newer 5.0 is the same on the XKR and the F-type.
Any part# and supportive year info is greatly helpful.

If anyone has investigated the throttles on these engines, please lend me your gathered knowledge as to save any wasted time.

Regards,
D. Fricke
