How to port a L92 throttle body? Who has pictures of a ported L92 throttle body?
Hi,
I would like to install an L92 throttle body on an LS3 intake manifold.
Hence I would like to port out the huge bump on the front and rear of the L92 throttle body.
I am aware that if you remove these bump you loose power if you install it on an L92 truck intake manifold. However I am using a LS3 intake manifold and hence the L92 throttle body is not ideal in its current shape.
I was wondering how the bumps have to be ported out? Should the shape be perfectly round afterwards? If so the gap between the butterfly valve and the throttle body will increase in my oppinion. Hence I am unsure how to port the throttle body exactly.
Could someone of you give me advise? I would also be thankful if you could post a picture from the front and back side of your ported L92 throttle.
I do not want to enlarge the throttle bore, just port the bumps out.
Thanks!

Porting a LS2 throttle body is easy. The L92 throttle body has a complex inner shape. I am not located in the US, so it is not worth it to ship my throttle body to the US and back.

If you are using the L92 throttle body with a truck intake you will loose hp if you port it. If you use the L92 throttle with a car intake, like I intend to do you gain hp if you port it. The inner shape of the L92 throttle body allows the air to better enter in the raised truck intake manifold. So it is great for a truck manifold but not so for a car manifold.
