This is a good read on how mounting the brake on the drive axle instead of the jackshaft reduces rotational inertia more than changing from a steel to composite brake. Pretty interesting read...
I also thought it was interesting that the stationary weight savings from a titanium axle was more effective than the rotational weight savings...
Out of curiosity, what does that bulky secondary weigh in at?

i just picked up some hauck srx race pipes and a high rev cdi for my project. also talked to doug flannery and he is going to port my cylinders and cases to match these pipes. sounds like over 200 bhp with this set up. getting excited to see this old iron on the ice.

I haven't seen the paragons used much in the drag racing world. Not saying that it wont work. I have had great luck with the bearcat secondary.

I know doug is the man with polaris. Cant wait to see what he can do with a yamaha. Should get hooked up this season so i can see your sled run. I have my own test track with timers, which it the only way to tune a improver/prostock.

yes sound good i have a place on gun lake we are out there alot on the ice. and yes it will be nice to see what doug can do with my 780. i just got some hauck drag pipes 9800 rpms also a hauck race cdi. i am having chromoly arms being made right now. still getting all of the parts i need for the build. just so busy around the house getting ready for winter. haven't had time to start this build. where do u run your sled at.sxr-x said:I know doug is the man with polaris.

I spoke with Mark for awhile about his racing days on the srx (The guy you bought the CDI and Pipes from) and he told me he made ~190 HP at 10,200 RPM. Thought I would let you know.

I completely forgot you were building a 780, that makes more sense now. I did end up buying the hood from him. It is on hold until the next time I head up his way but it is considered sold. Thanks again for the reference.

Also you should had purchased a 13.5x128 track. 4 lbs lighter. My prostock 800 never spun with a 128 with a wahl.
Eric do you have to go with a Polaris brake as well or can you mount the Yamaha caliper on the Polaris case?
Which Polaris case are you using?

jason,
I used the chaincase out of the edge chassis. As far as the brake i have mine mounted on the drive axle. Also i used the stock jackshaft that goes with the polaris chaincase and use a bearcat secondary.
