Here is a link to where I bought the T-body. RotaryGod linked it in another thread, thanks RotaryGod. Well worth the money.

That's the one I have, its an Accel TB, and they are 750CFM (unless modified by Accel). I am using Jay Tech\KG Parts manifold:


You could also use a Racing Beat manifold.

Did you get the fuel rails and lines with the TB? If so, those injectors will not work on the rails.

 

does the TB run like the stock one in regards to Primary and secondary ports or can the difference be adjusted.

 

You mean the butterflies?

If so, no they all open at once; and there is no feature to adjust them. It is a mechanic device, so it probably can be modified.

 

Yeah i was referring to the butterfly's.

 

The T-body was modified to 1000cfm and the price was 125$. At least thats what I was told. KNONFS, what are the size of the butterflies on your 750cfm one?

E-mailed, PMed KG last week.

Anyother ideas. Was looking at the racingBeat one. I will give KG another few days before I try the racingbeat one.

I haven't measured them, and the T-body is currently at the shop geting the fuel lines modified. It should be ready by Friday, as sson as I get it, I will let you know

 

Here's what size this one is. Can anyone out there tell me if this equals 1000cfm?

i use those tb's on lots of things, the stock size chokes are 600cfm, the max they can go to is around 950cfm when the chokes are bored to 39mm

10sec, looks like I got what I paid for. thanks.
It looks like he bored the top part of the t-body to make it a 1000cfm. The bottom looks untouched. You can see in the photo where he bored/reamed the t-body. There is a differance in metal color.
chuck

 

thats exactly what i do to the mate, i usually go to 40mm

here is a pic of one on a small block chev manafold

this one was bored to 35mm

 

KNONFS, how much did the KG LIM cost you, if you don't mind me asking? Or pm me the price. I'd really like to get a KGParts one but!.
chuck

 

Keith (KG Parts) I replied to your PM. LIM needed is for a turboII S4 motor for the t-body pictured in this thread.
thanks
chuck

 

In standard form I know they are no where near 1000cfm, I tuned a 383 with mpi efi that had the same TB, it was choking down on it at upper revs.. I would guess it what doing around 675-750 tops..Max

 

I bought a brand new one from somebody who bought one and never used it, I paid $250. I should be able to get you the measurements on the TB later on today.

 

with ur calipers at that angle, ur not getting an accurate measurement. need to use an ID gauge, then measure that with the calipers.

so how would u determine how much air flow a given bore size will flow?

 

Here's another photo with the caliper set at 39mm and angled strait. The bore on the T-body is bigger then 39mm at the top. The bottom of the T-body is bigger, (butterflyes). The smallest part of the bore measures almost 41mm. If 10sec is correct about 39mm equals 950cfm then It was a great buy for me. stretch8@qwest.net this is Bruce J e-mail address at auto-nomics, very nice guy to deal with, ansered my questions and replied to e-mails with in 24 hours.

Exactly what I got!

BTW - What are you doing in terms of fuel rails?

 

KNONFS, fuel rail? Going to try useing injection fuel line. My plan is to use the stock primary injector location for primary and two injectors at the t-body for my secondary injector location. Going with four ND 850cc injectors. (currently maxing them out) Then if things turn out OK I may go with four 1600cc injectors, all located at the t-body and get the auto-nomic fuel rail and line. Also, can you measure the top part of the bore on yours? Mine are close to 41mm. The throttle blades are bigger. It looks like he bored the top part only. Maybe our throttle blades are the same but the top is differant. just a thought. In my last photo you can see the bore is bigger then the caliper opening of 39mm.

For the price of 125$ this thing is well worth the money. Sorry guys but until someone shows me a mathamatical calculation that shows me it is not 1000cfm I am going to take auto-nomics word it is. thanks and yes I am alittle hard headed.

New racing beat LIM. Now I have to build another exhaust manifold.
