[AlteWagen]

Saw their new video but have not seen anything on this version of head.

I remember MOFOCO having a street fighter head but dont see it listed anymore. Anyone running this new head yet?

Side note: That is some crazy fuel stand off!!!

I saw that video on YT too. Like you I'd like to know more about these "Street Fighter" cylinder heads since that CB 2276 in the vid made 229 hp!

Any chance it’s a typo meaning their CNC Street Eliminator Heads? It does look like the cooling fins of an 044 in the yt preview.

"Development never stops in CB Performance’s Cylinder Head Department.

Soon to be released to the public, our latest creation, the 044™ CNC Street Fighter! This new port design was specifically developed to compete in the Real Street Drag Racing Class that takes place at the So Cal Drag Day and Bug In events. The intake port of the Street Fighter uses a smaller throat, but has more port volume than our prior port designs - the result is huge airflow that still retains high port velocity. An updated CNC combustion chamber and enlarged exhaust ports are also part of this new design.

Based on our updated 044™ castings, the Street Fighter uses a 46mm intake x 37.5mm exhaust valve, titanium retainers and our 650 valve springs. Max intake flow is 235 cfm @ .630 lift, flowed at 25”.

The 2276cc engine on 91 octane pump gas has 10.5-1 compression, uses a CB #2289 camshaft, CB 1.4:1 ratio rocker arms, Dual 48Weber IDA carbs with 42mm venturi’s, and a A-1 1-3/4 diameter exhaust system. All dyno pulls were done with the fan belt and muffler installed. Best power was 229 hp at 6800 rpm and 198 ft lbs torque at 5500 rpm.

Keep an eye out on the CB Performance website and social media for the release of our best performing street head to date.

044™ CNC Street Fighter"

Looks like a Superpro theory/design with a 46mm valve? Interested in seeing the chamber design.

It is still the same 044 casting used in all the other 044 heads, so I'm sure they just did a few tiny tweeks here and there to gain just a tiny bit more flow. There is no way they can find huge improvements with the same 044 casting. If they can find just 5 more HP it's still better. Yea to me it does look like the Supper Pro head with 46mm intake valves.

They created a new drag race class at the Bug-Ins so they had to create a new name for the heads to go along with the new class. A new name creates new excitement. New excitement may create new sales.

MOFOCO hopefully will be introducing their new wedgeport head which utilizes the same casting as their signature heads.

[fl59bug]

I believe the current CB head which has the 46mm intake valve is the Ultra Wedgeport rather than the Super Pro. My Super Pros came with "just" a 45mm "Supergrip" intake valve but I opted for Ti retainers and 650 springs.

I don't think the Super Pros get much love though from CB since they sell individual Supergrip valves in all sizes but 45mm. That said, unless there is a 45mm valve hiding somewhere on the CB site, when my SPs wear out I'll probably go with Ultra Wedges as a replacement. Then too I will keep an eye open and an ear to the ground on these Street Fighters depending on how well received and reliable they turn out to be.

235 cfm from these new heads is one cfm more than the current Ultra Wedge.

[Turnswrenches]

My old wedgeports are 46x37.5.

That Pump Gas Real Street Class the Street fighter heads are made for is awesome. Dave Volkstroke Ruiz and Dino Mendoza organize the coolest bunch of REAL street cars.

No race car shit. Must be all motor, no power adders of any kind. No fuel injection, dry sumps, no carbs bigger then 48's. No tilt front clips, Must have seats, door panels, deck lid. And their is no snooty show car requirements. You dont need have a million dollar show car like the Ren Kafer cars. Daves car has some series patina and rust yet cruises it casually everywhere and runs low 7 second 1/8 mile times with sky high wheelies. https://www.youtube.com/watch?v=kzwTI-QDMB4 and a really cool clip through town here: https://www.youtube.com/watch?v=01NHEBrSWbY

I ALWAYS THOUGH THEY SHOULD GO TO THE DOMINATOR STYLE PORTS. and size the ports to the engine cc.

Looks like it’s replacing the Ultra Wedgeport all together. I guess it’s just another option for HP. The Superpros claim to fame was that they flowed similar to the Ultra Wedgeport, but with an 8cc smaller port volume to up velocity. The Street Fighter heads have a different port design to create more velocity, but are actually 1cc larger in volume than the og Ultra Wedgeports. And the “heart” style chamber is similar to the Superpros. Pretty interesting. That port size just makes you wanna say Reeee-co-la....

[sled]

Im not sure if Pat or anyone else at CB is reading this, but if so, it would be wonderful to see they dyno graph for that 2276cc street fighter engine.

Im really curious what the numbers are from 2500 to 5500

90cc is big but if they discovered some tricks in the port design, in conjunction with a really good chamber (and 10.5:1 comp), it may be no slouch at lower rpms.

David won a pair that Pat Downs donated as a prize at the last event. He said he is putting them on his car, so I guess we will see if his time improves or what his results are. I'm going to be running with that class from now on and joining them at meets and such. Even tho I'm not nearly as fast as them I'm the only one running full street trim. Dressed to impress

I got plans cookin' for a 230hp N/A moster tho, give me a few years lol

Chuck Studler runs the Street Fighter heads on his Geoff Hart built pump gas engine. At the last race, he ran 7.20 at 96mph in Real Street on the 2nd pass the car ever made.
