Ive gotta a 2000 Camaro SS and I was wondering if the BBK 80mm t/b really works. They promise 8-10 rwhp, but I didnt notice a difference. The only difference was that it made more noise and had a whistle to it. It also has a spacer that goes behind it and I was wondering what difference would it make if I was to remove it. The trottle body has a bigger bore and then bellow back down with that spacer. Is it possible to make the bore bigger on the intake. Will the Holley intake make the difference for the t/b. Does the intake have a bigger bore than the stock LS1.

Wow you got a 80mm throttlebody so early! You should have waited till you got heads,cam,and headers to get the full benefit from it. You aren't going to see much from it now. It's gonna suck alot more air in too. Watch your a/f tuning.

 

"It's gonna suck alot more air in too. Watch your a/f tuning."

How is that? The inlet of the intake manifold is no bigger than the throttle blade of a STOCK throttlebody. I don't care if your throttlebody is 120 mm no more air will enter the intake manifold due to the intake inlet right behind the TB being only about 75mm.

And even if it weren't, that extra airflow would still have to go through the MAF sensor which would read the extra flow. The computer through the MAF and O2 readings would correct the fuel/air mixture back to normal. Otherwise you'd run leaner in cooler weather than warm.

 

I was always under the impression that the 80mm throttle body allows more CFM to enter the intake which would result in the 8-10 HP increase.

 

The BBK throttle body in my opinion is worthless junk. I had one once and it was nothing but trouble and adjustment. Get a port and polish throttle body and enjoy the gain in power.

 

I would just buy a Shanner ported TB (which I am) You can port your own TB, however, if you don't want to waste the time then the Shanner is a nice option. 75mm nicely ported and has the bump-stop mod done to it. And the price is minimal, I believe it is $170.00

 

The Shaner S2 mod was a kick @ss one to be sure.

I never believed in the throttle body mod but all the guys over at www.z06vette.com were raving aobut it..

So I gave it a shot..

Whoa! cool mod and inexpensive to boot. Can't give any specific performance numbers on it myself..but at 169 dollars it sure was worth the money.

The car revs so much freer and from a perspective of noticing a difference in the car..I noticed it from the first five minutes behind the wheel of the car with the mod installed.

go to www.ragingmotorsports.com. he has nice cheap ported tb's, they might not be on the site, but call.
I think they are a little over $100.

It will whistle since the throttle body doesn't have a lip in it like the stock one. My throttle bodies also have a slight whistle, but I forgot what the stock one sounds like.
Actually the only really good use of the BBK is on the Holley intake when you bore it out.

Either way a throttle body will improve the flow on your intake system and will gain HP. The more power the engine is making the more a ported throttle body is needed.

I didn't know Shaner was up to $170! a TB! Check out my site! http://www.lswon.com/bret%20bauer/bretbauer.htm $110 for a ported TB. I have to say that Shaner also does good work, but I will also put mine up against his anyday.

Ok! So right now Ive got the BBK and was planning on buying the Holley intake. Should I keep the BBK and when I get the Holley, go and port it. When you say port it, does that include the inlet on the front of the intake where the t/b goes in. Or does it only mean where the ports of the heads are. So would the BBK be of some use then when the intake matches the t/b. I really didnt notice any gain in power when I put the BBK on.

So even if the BBK is 80mm, it bellows back down with that spacer. I was told not to remove the spacer. So what good what it do if I was to bore out the inlet on the intake if its not going to match anyway. I dont remember, but even with the spacer, is the hole on it still bigger than the inlet on a Holley. By the way, is the inlet on a stock LS6 and a stock Holley the same, or is the Holley bigger.

Or you would want a Spacer that was 80mm all the way thru. The inlet on the Holley is the same as the LS6, but the holley can be made bigger, the LS6 can't!

Bret

 

So how many mm is the inlet on the Holley intake? If it is indeed smaller than 80mm, then I would bore it out. But like I said, I was told not to take out the spacer. But I dont see why I would need it if I was to make the inlet on the Holley bigger to 80mm to match the throttle body. So my question is...Can I take the spacer off the back side of the BBK, if I bore the inlet of the Holley intake to 80mm to match the BBK. If I cant take out the spacer, then it does no good to bore out the inlet on the intake.

 

Yes.

Now a question for you........

Why do you want to spend $400 on a BBK just to put it on a Holley intake that is $500+?

The Holley heat soaks, weights more and is only needed if you port it and it's for a big cube engine.

I am willing to be that one of my 75mm ported throttle bodies along with a LS6 intake which comes on a 2001-2002 f-body will be a better performing car.

I want to have everything that bolts up to these motors and Holley is an aftermarket intake and getting a LS6 would just be stock looking. I know that Ill get more power out of the LS6 from my LS1, but if the Holley has a little more and more can be done to it then I will spend the extra $100 for it.
