Brodix cylinder heads for the Duramax
- Thread starter COMP461
- Start date
These numbers are for LB7 Federal Heads Stock.
These numbers are what just about all of the stock Dmax heads flow. LB7-LML. The port shapes and sizes are all basically the same.
The only exception is the LB7 EGR head. The intake ports on the EGR head flow substantially less. If I recall correctly about 40 cfm less. The exhaust ports are the same as federal heads.
So here they are. Let the marketing and advertising of flow numbers begin. :rofl:
That is nearly identical to the stock flow numbers that I have on my lb7 heads. 180 on the intake and 142 on the exhaust at .500 lift.

X2, Guy's heads are all that I have sold my customers with great success over the years! I have been fortunate to be the test dummy for these new Brodix heads and helping Jeremy with the design and porting and fitment and I must say it has been a long road to get to this point. I installed the first set on my truck back in March. I am getting tired of swapping heads on my truck, but all the testing has been worth it. The test data is eye opening and has really changed the statis quo in my eyes. You guys are right, they are expensive and honestly they are not for everyone. The top 10-15% will buy these without batting an eye because they are more than worth it in quality alone and the performance increase is just icing on the cake. Look at my truck for example, with these heads I ran 10.96 in the 1/4 with a vgt and a single pump and did it while running 1400egt's at 45psiboost and 65drive. Put twins on and picked up 190hp 60psi boost 85drive. On the sled pulling side of things these heads have allowed us to run much larger chargers than before without issue and we have picked up a solid 600-1000rpms with them. Cams act different with them. The flow numbers I have show the stock heads at 183cfm intake and SoCal stg2 in the 230cfm and the Bromax Stg2 heads on my truck are in the 290cfm range. The big difference is how much airflow is increased at a lower lift of the cam vs a stock/ported head. They will only get better with time. They will hopefully be ready to bring to the market very soon!

Its good to see brodix getting into the market. They always have a good casting that people can work with. I also think to most have no idea the level that Guy Tripp brings to the head market! He has forgot more than most of us will ever know. He has been at a very high level going back farther than most have been alive. LOL :hug:

Eh this has been discussed to death as to why Dmax parts cost what they do it's very simple. Using your example how many BBC are built being built and CRATES of rods sold compared to Dmax motors? It's probably a 1000 to 1 ratio! Heads are probably worse in actual numbers sold. I'm sure you know this anyway your're just stating your diss-like of the price .
I think they should have shitcanned the glowplug and figured out how to put in a second injector ...
It makes a lot of sense. Big nozzles have issues at low boost, so run a set of little uns and biguns. 800rwhp out of the little ones, then big ones should be able to add 1200 more at least.
EXACTLY!!!
My good friends Supra makes 1400hp and it runs on 6 injectors up to xx amount of boost then the second set of 6 injectors kicks in for a total of 12 injectors. I thought of this for the Dmax and it would be very very smart but could EFI live support the tuning that would be needed? Im sure it could be figured out but its all just $$$$$
Nelson Racing uses a similar system with 16 injectors on they're twin turbo motors. Basically has two fuel systems. Primary injectors run pump gas while secondary injectors run race gas. Pretty cool setup
How hard would it to do a set of IDI injectors in the intake runner like in a Gas EFI lives setup.
Just wait until the Dmax head is being produced for a while & by multiple manufacturers, the prices will lower to compete for our business.
Won't these new heads have to be reworked? $$$$$$$$$$
I bet if you install them as is they won't flow as much as a custom stock head. So now we are looking at 10K for a good set of heads.:dontknow:
