Ported 80MM Factory Throttle Body to 84MM

[gameovergt]

Got a 2016 GT TB off the 'Bay for $80 shipped & sent it to Maxbore.com for Porting/Shaft reshape ($160.00). Just got the TB back from Jorge. Here are some before and after pics. Leaving the plastic on the TB until I order the GT350 manifold kit. Got a little more invested in than upgrade to the 350 TB but didn't want to deal with tuning issues. TB went from 80MM to 84MM. I have seen factory TB's on Ebay go from $35 to $150. So many parts to install/so not enough time. Really gotta get the LongTubes on!

Ooops. Forgot to post the ported pics. Here they are.

Got bored and put it on. Need take car out to see if throttle is more responsive.

Throttle response is faster/quicker. Definately worth $160.

Feel any power increase? How long did the process take?

IDK if gained any hp by seat of pants feel. Mailed tb out on Monday. Got it back the next Wednesday.

How is the idle?

Idles little lower at about 600 rpms but no problems

Awesome thanks..I've ported a few and was just thinking about porting this one and ran up on your thread.

Just an FYI. Maxbore cannot do the GT350 TB.
