How's this ported TB look?
 

Should I do anything else to it or install it and go!

Still needs enlarging just in front of the blade.

Thanks, I bought it used but it was done by Vengeance and I've only heard good things about their port work. I thought about epoxying that one area that's void.

It's not bad but they could've removed more material that's for sure. Stay away from the epoxy. It marginally (if at all) helps airflow and if that little piece lets loose do you really want it flying past one of your valves and into a cylinder? Oh and your sig says you have an H and an X pipe...how does that work?

knife edgein the throttle blade is a must.

You can do whatever else you want to, but you wont gain a single pony. We have tested this extensively.

Wow someone sounds a little overly confident. I'm sure it would help at least a little bit to open up the front a little bit (there's a good amount of metal left right where the intake tube mounts). Doing this, cutting the bolts down to be flush along with knife-edging the blade WILL help. Now it may or may not be significant but that's another story.

haha. im kinda interested in the h-pipe and x-pipe. but yeah, i would most definately stay away from epoxy. the risk is just too high.

proof why you say that?

Im not overly confident in the least... I have simply ported THOUSANDS of throttlebodies and I have dyno tested ALL of the options... Knife edging/epoxy/removing half of the shaft etc etc... Removing more material from the TB can cause issues with high idle and has not shown ANY gains in throttle response or horsepower.

For one its filthy... The shaft should be cut in half. I look at it this way. IT lets in more air, it cant hurt. It doesnt look like much material was actually taken out. The face of the TB shoulda been knife edged as well....

But hey if it works fuck it.

I'm talking about material at the opening of the TB, not near the butterfly. You guys got it pretty flush in the blade area which is perfect. I know that if you take off too much there then you're going to get a high idle...I know b/c I screwed it up on one of the TB's that I ported! We're just saying that halfing the shaft, knife edging the blade, and cutting the bolts flush all help it's just not very significant as you found with your dyno testing of THOUSANDS of throttlebodies :D

The shaft is cut in half. ;)

Thats a clean TB. Just throw it on.

Thanks for the info Ron, didn't mean to get a flame war started, I installed it and the throttle response is improved for sure.

knife edgesing the blade shows no gain. dyno tested

No to epoxy! I see this too many times ---> https://ls1tech.com/forums/generation-iii-external-engine/873208-epoxied-ported-throttlebody.html

half shaft the bottom shaft like i did...:secret:

I know I noticed the difference when I put mine on.

I don't agree. Removing half the shaft and knife edging will improve flow. It may not show any gains depending upon what the car needs. If the TB becomes the flow restriction, then I gurantee it will show a gain. If it flows more air, and it becomes LESS restrictive, it will make a difference. If you dont need the extra flow, it wont make a difference.
