Looking for a 50-55 MM sidedraft Weber and manifold for a 6 port 13b. Who sells this???

 

check with racing beat.

 

I will call them. Their website does not show any weber of this size.

 

I don't think they do a sidedraft that size, just the IDA which is a 48 that they modify to 50 or 51 mm and rejet.

 

rotary shack is your best bet.

 

What kind of motor is this for?

 

Street port, 6 port 13b with high compression rotors and larger older center iron.

Weber does make a 50 and a 55 DCO sidedraft.....seems like Atkins does sell a one peice manifold to hook to a 6 port motor.

 

weber does indeed make 50 and 55 DCO's...ive got 50DCO SP tucked away in my garage right now for a motor that could use it

 

i have 50 &55 webers in stock. i like to run the lower stock manifolds (cleaned up and de-smogged) with the pineapple 6 port sleeves. no low end lost and lots of top end


the best 6 port wrap around for all top end power is the star race car manifolds designed for the formula mazdas all top end tho...

 

well look whos back

 

I saw the wraparound manifold that star is selling. Looks just like the manifold that Pierce manifolds is selling. Seems like a nice unit. Why would this manifold be all "top end power" vs. the stock lower.

When you mention pineapple sleeves, are you removing the actuators and running all 6 ports open all the time??

 

the unit pierce sells is DEFINATLY NOT the same as a star unit. the star unit is made specificly for a top end powered setup with a close ration gearbox to keep in the sweet spot for maxium power(only available from star)

the pineapple sleeves work in conjustion with the factory manifold using the actuators to open and close them to reep the benifits of the six port design intended
