COMBUSTION CHAMBER & INTAKE PORT MODS! "V"-GROOVES PLUS INTAKE PORT VORTEX GENERATORS!

A LOOK INTO THESE HEADS AND JUST CLEANING UP OF THE CHAMBERS IS ALL NEEDED BEFORE ASSEMBLING AND INSTALLED ON OUR SBF 9.5 DECK BLOCK.
VORTEX GENERATORS PICK UP ABOUT 7-8 cfm ENHANCING FLOW ACTIVITY ON THE SHORT SIDE RADIUS.
MOST HEADS WILL RESPOND WHEN STICKING A FLAT SCREWDRIVER ON THE PORT FLOOR AND WATCH FLOW PICK UP!!

Wow, beautiful cylinder head! Big air flow number.

[@benalamedaracing2765]

Thanks!

[@patrickmarcello5103]

That head is flowing some serious cfm!

[@benalamedaracing2765]

Yes it did flow 435 @ 28 and I know my bench flows on the low side and the ports are not overtly big!

[@stephenhans189]

A electrical engineer in ky was doing back in 90s to stock head for people competition cars . Several of them still holds record et's

[@warrenglover]

Heeyyyy cool thanks Ben....

[@Adrenacyde]

Beautiful. A couple more CFM than my TF 205 11Rs 😆

[@benalamedaracing2765]

Just be aware the 11R is a good cylinder head but avoid going much over .600 lift. I tested them when they first came out and they became turbulent at higher valve lift pass .600.

[@Adrenacyde]

@@benalamedaracing2765 Lift is .666/.664 custom solid roller 8000/8200 RPM

[@Adrenacyde]

These are the "CNC Comp Ported" ones with 54cc chambers.

[@Comet-hn3gm]

@@benalamedaracing2765 I get the turbulence in a static situation like a flow bench, but how dose that relate in a Dynamic environment like a running engine ? Was testing done to quantify more lift was detrimental ? I'm not being sarcastic, I truly am interested. Wouldn't the rest of the combination have a factor such as headers etc ?

[@warrenglover]

Ls 5.3 too ?

[@suntzu5836]

Wouldn't a vortex generator on the floor of the exhaust port be applicable also?......Or is the swirl only to mix fuel/air?

[@benalamedaracing2765]

No need because the flow you get is wasted energy wherein the intake we are trying to keep the air/fuel from separating and reducing the homogenization of the mixture.

Did you ever experiment with a notch vs the v groove?

[@benalamedaracing2765]

I do not understand what you are saying "notch". Could you clarify sir and let me see before I can comment. Thanks.

[@williamzoom]

@@benalamedaracing2765 Watching it on a phone it looked like the notch was cut with a high spot in the center, watching it on something that I can actually see it closeup I see it's not, my mistake!

[@tonymontana4349]

Sorry man I came late in the show why are there grooves on the head

[@benalamedaracing2765]

Please watch the video about combustion chambers here on the channel. It is too much to explain in brief the details.

[@tonymontana4349]

Gitcha I’m following a lot of ur tips on an engine build. Ring gaps is one of the questions on a stroker 4”8 10.3 compression with a 28cc dome clearance .002 is it good to gap the upper larger than the second?

[@tonymontana4349]

Thanks I appreciate ur videos I’m sure I’m asking too many questions happy new year n keep racing buddy Later man

[@Nothingtoseehere363]

2nd ring should be bigger gap than top ring @@tonymontana4349
