Bo's Ported Throttle body

[axis]

Due to several inquiries, Bo will start doing shaft mods to the Vmaxx TB's. You can still go through Jason for those. I don't think he has one on hand so it's probably going to be ship it in, mod it, ship it back, unless someone wants to donate one.

Saw this today and in Super Chevy and thought it was pretty cool.

We came up with a list of four mods that we thought would hopefully get our Heavy Chevy deeply into the 12’s, but keep it commute-friendly. An air intake always tops our list when we start digging into a new car, so we went ahead and procured one from the folks at Cold Air Inductions. Highly popular with the fifth-gen crowd, it’s easy to understand why. It’s very easy on the eyes and testing has shown it’s one of the best designs on the market. We also nabbed a ported throttle body from Bo White, well known cylinder head and throttle body porting expert. We then sourced a Powerbond 25% underdrive crank pulley from Scoggin Dickey Parts.

Got one a few weeks ago. Looks great, performs even better.

Bo FTW.

Wonder why the throttle blade (shaft) bolts are left so long?

They are the same length as OEM, just grade 8. Typically he grinds them down even.

Yup, Bo will half shaft your VMAX throttle bodies. Unfortunately we don't have any, and I don't plan on buying any to go into circulation, so if you do want this done to your VMAX you will have to ship it straight to Bo, he will modify it, and ship it back.

10-4. I went out last night and got bolts to use for when I do the shaft mod this week to my v-max. There were a lot of length variety's in this bolt size at the hardware store near my location. Reason why I asked, but you can easily grind them to length afterwards too.

That's what I was thinking to. Am I missing something? Isn't he just taking the shaft out and plugging the holes with nuts and bolts? How much hp could possibly be gained by doing this?

Not sure what you are thinking of plugging holes with nuts and bolts as the throttle body shaft is threaded. But you will need to source yourself a 5/8" expansion plug to cap the end of the throttle body when you put the shaft back in it and it all together. You will destroy the old plug when trying to get it out to get the shaft out. No other way around that.

He's cutting the front half the shaft off, then reattaching the blade with higher strength grade 8 bolts, for the added strength. The added flow comes from the lack of half the shaft. Essentially, less of a restriction. Don't know what you're trying to say with nuts and bolts. There are no nuts on the TB as the back half of the shaft is threaded. The grade 8 bolts are the exact same length of the oem screws, but have a bigger head. With that pic you can see just how much shaft is taken out as the bolt would be flush with both sides of the shaft in place.

He doesn't grind the threaded end of the screws because a mechanically fastened connection is stronger with 1-2 exposed threads as opposed to flush. Standard engineering practice. I deal with fastener strength all the time at work.

Time to get to testing!

That's a great comparison picture!
