Not a problem! Good to hear your back up running!

 

Have you guys seen any real difference in porting your TB. I was thinking about doing mine but i talked to my buddy the other day and he said he done his but felt like he lost some low end power so he put a velosity stack in it and it picked the truck back up... Any ideas??

 

yeah leave it alone.

 

i dont think i picked up any real power, just throttle response seems better.
But for the amount of work that has to be done its not worth it. Sure looks purty tho

 

Yea, with the intake tube off lol...

 

The only possible way you'd "lose" anything is by trying to "hog it out", which isn't the goal when porting a throttle body. The goal is to smooth the airflow coming through what's there, not really taking a lot of material off, except where it's a restriction. A half inch or so in front of the closed throttle blade is a pretty big hump that is very defined and easy to see and feel.

If you have an air compressor, a dremel, a carbide burr, and a handful of sandpaper rolls, you can do it yourself in an hour. You can also take material away from where the throttle blade linkage hits at WOT so that your throttle body actually opens up a full 90 degrees. Stock, they open much less than that.

Anyway, I did the one on my 2000 Camaro SS, and just did the one on my 02 Silverado, and both gained a noticeable difference in throttle response, which is the goal. HP gains, if any, will be VERY minimal, but if TB is ported properly, it will always give you better response. It's been proven over & over, and is a very cheap (or free), and effective mod. Most porters agree that "polishing" the inside of the TB, and "knife-edging" the blade are a waste of time. A simple port job is all that is needed. Polishing is usually reserved for exhaust ports.

 

lose low end? LOL. I put my stock TB back on and it felt like there was no throttle response down low.

 

Ill just buy a 80mil BBK and be done with it...

 

Why not just buy the 90mm intake, tb and conversion harness if its that important? What does BBK Charge for a couple more mm? $370?

 

for most trucks on here a 90 is extremely overkill!! When you port these throttlebodies just remember VELOCITY, cut into a funnel shape as much as you can.
