Centerbleed on a big bore

[DylanS]

Hey guys, I have a homemade centerbleed chamber someone had made in similar spec to The original WDK laydown steel chamber that needs some small finishing work
Was wondering if anyone had ever tried running a centerbleed on a 1000+cc motor and what it brought about

 

[Quinc]

People have converted the kawa1100 chamber to center bleed. And lots of people running the tnt chamber on big bores.

I run a TnT centerbleed on TPE 1021 with very good results.
Like anything else, it needs to be tuned for the application

I read into those chambers too, wonder if anyone ran them on gp800 cylinders
Noticeable difference between the two?

WDK uses the gp800 cyls on his motors. I have only seen them run with the WDK laydown pipe.
Im not sure a manifold is avail to run the TnT centerbleed on those cyls?

I run centre-bleed on my 1200. Seemed to give more power down low. Be careful of back-pressure, you need a slightly bigger stinger compared to end-bleed

Yeah I have a first gen cast manifold but I’m pretty sure you’d need the latest milled to run that chamber or so I’ve been told

Yeah I’d be curious as to what diameter to weld on, the guy before me had the stinger on the top side of the pipe for some reason, so it has to be removed and replaced anyways

I am running a 90-deg 47mm-id(2"-od) at the 3o'clock position. Rest of my system is 63mm. I ride at 4500ft so my stinger can be smaller than someone at sea-level.

Thanks for the info, I’ll get my measurements and probably end up somewhere around the 2”ID. Not sure on what position I’m going to run yet, might have to tweak it to fit the hull. I need to get rolled steel too.
