I can't wait to install mine

 

Them flow numbers don't mean squat without the intake bolted onto them.

 

Don't be a hater.

 

Them flow numbers are before and after numbers from the same company (TEA) on the same heads, thus the relevance of that "squat"

 

That's on a bigger bore, apples to oranges, but great numbers nonetheless!

 

Yep. Love my stg III 6.0L TEA heads!

Welcome back Brent!

 

Here are my flow #s w/o the intake and with. Yes they're LS6 heads and I love em!

Lift(1) Intake(2) Exhaust(3) through the manifold (4)
(1) (2) (3) (4)
.100 72.8 58.7 71.2
.200 140.3 120.9 137.3
.300 204.8 175.5 198.2
.400 256.0 228.5 241
.500 294.6 263.9 271.2
.550 311.6 273.0 283.3
.600 322.5 277.8 294.1
.700 336.6 307.6

 

what a deal!

 

Who flowed your heads with the intake? Every time I flow a head with a LS6 intake I never get more than 260cfm, with my ported LSX and my Judson LS6 heads I got 284cfm

 

TTT Verbs?

 

Not true.
Let’s put it this way. I want to see the potential of the heads, not the potential of the intake on them. If I am going to flow the heads with the intake attached, I may as well flow the heads with the throttle body attached also.. If I do that I may as well flow them with air bridge attached and if I truly want to see I would have to attach and air filter and a lid. Of course then I would have to know if it was an Fbody or a C-5 or C-6 or a truck so I knew which downstream stuff to install. And if I really wanted to know how it was going to work in "real Life" I would have to flow it at however many inches of water that particular engine would flow (100 plus on most) and our bench only goes to 28 So I also guess we should also heat them up to 180 deg before we flow them on the intake and 1000 plus degrees on the exhaust side so we really know what the head is doing. I guess we should also wet flow them since they are not ran on a car with just "air" and all of our exhaust flow test should be ran through the full exhaust all the way back to a tail pipe. We should stock every type of exhaust made for all of the above named cars so the numbers are accurate. But it just takes to long to do it that way
So we will just stick to flowing them the way we do it now Showing before and after gains on the same bench,flowed the same way if needed.
BTW the views expressed are mine and mine alone.

 

I have a port matched 78mm LSX manifold, flowed by TEA. I shall be posting some 465-470 rwhp/420-425rwtq #s in a few weeks now that I upgraded my headers and am adding the 90mm/90mm setup.

With 60lbs wheels/tires, heavier than stock driveshaft, no EWP, through the exhaust, stock flywheel, full belts, i.e. NO dyno tricks, 12 bolt/4.10 gears and 10.8:1 compression w/ 28 degrees of timing, I'd say TEA did a fantastic job with their porting on both the manifold and heads . These heads could easily make 500rwhp on a more "dyno friendly" car.

 

Well said Brent, Isn't flow numbers like dynoing a car or drag racing for best times, their are so many variables involved, that it's very hard to get accurate numbers?

Hey Brent, BTW here's a pic of my less miles camaro!

 

[QUOTE=z28man]Well said Brent, Isn't flow numbers like dynoing a car or drag racing for best times, their are so many variables involved, that it's very hard to get accurate numbers?

I think he is making the case to keep the variables to a minimum.

 

I wonder if TEA uses a radius or something when flowing with the manifold. Like I said I have tested sheet metal intakes to only 265cfm through the intake. I did a full port job of my Fast 90/90 and only got 284. I trust my #'s as I seem to make good dyno and mph #'s for a drag car. Anyone else ever flow there heads with the intake on?

 

We have flowed heads with intakes attached. It is not cost or time effective though. And there are a lot of variables that should be met. Brian Tooley's heads and intake were tested together as well as some others. I could get into other things such as bench differences etc. But all of that will be covered in the near future.
Thanks Brent
BTW Nice looking LOW LOW Mile Z

 

the FFHP heads are mine and we used my intake. the PP heads are just a set i tested, different ls6 intake. all other variables the same.

i've never been one to believe TEA's bench, but thats just me.

 

300+ cfm with good midlift is very good for the 3.900 bore stuff.

 

So gee your #'s seem to be dead on with mine concerning the LS6 intake, hhmmm?

 

Well I had a choice when I orderd my LQ9 heads from FFHP. Either the PP CNC or the TEA CNC. I have the TEA CNC on the way So I will also get them tested one more time before I put them on the car.
