Anyone else other than atkins?

Thanks, Ed

 

My REPU wants one too!

Hurley don't sell manifolds any more

 

Thanks for the update that is no surprise though he still has them listed on his web site. Mine was the first 13B intake he made. It was a special project, one-off, and I don't know how many other 13B's he made after that. Give him enough money and the blank plate and he still might do it. Anyhow, probably too expensive for anyone in the states so take him off the list.

 

I prefer the ONE piece intake manifold for 4-port 13b. Anyone sell one of those?

 

A straight shot manifold would be perfect! I think this type of manifold would make a streetported 13B 4port SCREEEAAAAMMM...

Thanks, Ed

That kit comes with a Weber 45 DCOE carb, linkage, blah, blah, blah. If you don't need all of that stuff, you can call Nick Van Nugteren, and see if he can sell just the manifold. I dunno, though.

 

got one. 12-A one piece with "12-A-to-13-B adapter plate.

 

I have a Racing Beat prepped dellorto and a Racing Beat upper and lower manifold set for it.

 

A straight shot manifold would be a turd on low end. You'd have no air velocity going into the motor. You might as well put in an i-VTECH

God help me for speaking those words....

 

why would it have poor low end ? explain please

I think he does....

 

I own the Lake Cities straight shot manifold and with chokes 2mm smalller (37mm) it still made more HP, much better throttle response, and equal torque compared to the RB manifold with 39mm chokes.

 

I have one of the Atkins manifolds lying around. I never used it. It is very poor craftmanship. It is a cast piece and apparently the cast really sucks. I've had to go back and correct so much. None of the port openings lined up with those in the engine. How hard is that to do? I can guess closer than that. One of the primary ports was higher than the other! I bought it to use on a T-II engine but it is for a 6 port engine. He said they are the same and are compatible and I should just use it. They do bolt up since they have the same bolt pattern, but they aren't compatible. When I asked if it needed any modification to work, he said no. It isn't even good for a 6 port engine. There is no port divider for the aux ports and the holes aren't even close to the proper size. I have tons of plastic steel epoxy in that manifold just to correct the errors. Even the 2 round holes for the carb aren't actually round. I had to go back and fix that too. They are about 55mm in size which is plenty big though but it would suck for anything smaller. The runners themselves are not constant in area and the rear rotor runners collect at a different distance from the engine than the front rotors do. It is a giant piece of cast aluminum crap. They do have a straight shot manifold which appears nice but it may just be the same one you can get elsewhere. The Atkins are nice people but they can't make cast manifolds that are worth anything.

I also have a 6 port Racing Beat Weber upper manifold lying around and an old style 13B lower manifold as well.
