It is still a work in progress, It has about 8 solid Dyno hours now. It is a ton of fun to ride with the stock swingarm

More impressive than the peak HP number is the "more than usual" linear curve of power and torque...that is very impressive.
I'd bet that thing is a LOT of fun to ride. Very nice work!!!!

That was like an 9 Second pull. The cool thing about the Superflow is you can load it similar to the real world. It helps us hill racers who are tapped out for 10 seconds sometimes. I have a swingarm coming this week and I will be racing it this weekend at our King of the Dunes race. We will see if all the work on the dyno paid off.

Nice numbers. I,ve been thinking about turning my 350 in to a 392 cub next rebuild.

 

[RJ65]

So do you guys run big bore or small bore pipes on the 392'S?

I am not sure we have the "right" pipe yet. We are still testing. If you are interested in the 392 cub. Give Nate a call and he will go over the details.

 

[badassbanshee479]

nice numbers!!!

My 421 from Nate had a good power curve from 8,000 up to 10,000 where it falls off just after 10K. My curve didnt have a dip at all just steadily up to 10K. Still tuning on it and going to alcohol so we'll see how it does when we're all done. I like mine.

Nate sent me a different set of pipes and we are up to 114.1

 

[Fouledout421]

thats some impressive #'s for sure!

 

[Radar]

You were using inframe BB shearers right or are you the one who has his out on loan.

 

[tre717]

those are great numbers! thinking about building a 421 over the winter.Hope I can make some ponies like that

 

[Boston Racing]

I have Nates on loan, Actually both sets I have are his.

 

[Radar]

I knew his were out on loan. Which pipes made the most HP? As far as inframes. What did the 111 and the 114. I'd love to see 111 or 114 out of my 4mil.

It did 111 with the BB Inframes and 114 with the SB OOF's with some slight modifications

 

[Radar]

I'm hoping for #'s like that or better with my 4mil with inframes. I'd give up 3 hp to have my inframes.
