5.7 Vortec Throttle Body
 

anyone know wat kind of gains i would get if i shaved the restrictors on the TB blade?

no hp gain it will just make the throttle more touchy from slow speeds

I took my restrictor plate completely off and put two new rivets back in the holes. It did make it more touchy.

I have a 80mm bbk thorttle body sitting at the house. Used it on my 96 5.7 when I had it. If anyone is interested I'd sell and ship it for $100.

exactly wat i did!!!

tools
torqx screw driver
flat head screw driver

first off, take the two torqx screws out and slide the TB blade out, then with the flat head screw driver take and pry the restrictor plate off, i sealed the two holes back with steel rivets but epoxy or silicone will work as well. NOTE IF THE 2 HOLES ARNT SEALED CORRECTLY IT WILL RESULT IN HIGH IDDLEING ISSUES!!

RESULTS 25% more air flow

Haha glad you got it done, nice to have a pretty much free mod...that works! Truck still isnt anywhere near fast. Lol

yes indeed!!!!!!! free mods are the best. but not best HP gains lol :D

that't the first thing I did on both of my OBS trucks when I got them. I like the better response, and I'm sure it helps some, even if not a lot, at WOT. Good mod and free for me! :D

Still have it by any chance? I know it's been awhile since you posted but just wondering?

Sold
 

I’ll take that deal. Did you see a noticeable improvement in the way it ran?
