Cb750 racer here you go, both E and F Rajay maps, along with different blade design the E wheel and compressor are larger. It has been my experience that on a big Kawasaki the smaller F setup will make almost 300rwhp, I would guess the E to be good for roughly another 100hp.
Wow, Those Rajay "F" series compressor maps are like hens teeth. I really do appreciate you sharing this! I'd love to read more about some of your Kawasaki's. Sounds like a #$%*in stable!
Looks like I'll still be in peak efficiency with what the boost I plan on running which is awesome. I hope the backpreassure isnt too crazy but the norris stage 3 cam should really help keep it from making it to the combustion chamber.
Much more progress on the engine behind the scenes. Ended up having to ditch the MessnerMoto cam chin tensioner as there was no way to install due to cylinders 2 and 3 being too close together from the large sleeve OD. I posted further details on his thread. Now have one of those metal ?Cappenelli? Ebay tensioners in there now. Mike also shortened the cam chain back down to 94 links for the stock style unit
You can see engine #1 from AT&S creeping in the back of the picture. There's also so need to hold the cam chain up better off just dropping it in the cases so it's out of the way.
Dam that copper headgasket looks good. It was sprayed with that permatex copper spray a gasket for that extra level of sealing.
Also had to end up running stock head nuts due to me sinking in the studs too deep. I should have set them higher because the aftermarket head nuts are much taller but truthfully I don't think the difference will matter all that much. Mike also used 4 acorn nuts with copper washers for the studs that are exposed(410 series head) to prevent oil seepage outside of the engine through the threads.
This engine spins like butter
