That class runs 6.80s to 7.10s, around 200-220 MPH, so it aint gonna be easy. It will be expensive! Reading their rulebook, they don't show any love for V-Twins.

aint going to happen.the only gas HD that would even come close is brownes turbo bike (runs in the 6.95-7.10 area),but its got 10" slick.plus its a completely one off bike and you would be looking in the 100K+ area to build one

Kind of what I figured seeing how the outlaw street bikes are pretty radical and only run 8.50s

The *problem* with the harley is the pathetic shared inlet tract.

In an ideal inlet tract you want something as straight as possible, and as close as technically feasible to the valve stem so the inlet gases go straight "down" onto the poppet valve and feed equally around all the edges when it opens.

Contrast that to my stock hd, essentially two 90 degree bends within 4 inches of inlet tract, and worse still, a common inlet tract for two cylinders ...

Rotate the read head 18 degrees and fit twin carb and you'll start to make real power on a n/a harley, straighten the inlet tracts (custom head) and you'll make loads more.

Rules though, at what point does it stop being a harley / stock / within class?

There is a reason that something called "Harley Drags" came into being....
No Cars, and no Imports...Don't need 'em.
So...The question about can a Harley be competitive? Only Harley's and "Clones" and Indians, and Victory's are even Invited....

I used to run at the LA Country drags. I learned to race at LACR. Won a modified class trophy. Those days are long gone and LACR is a gravel pit now.

West Coast-AHDRA kaput. Tracks closing and no organized sanction out here, except NHRA, which runs some regional events. Unless you are top fuel, very little turnout, except imports.
Pacific Northwest has some regional racing.
Ran a couple races with the WMDRA, even though they didn't even have a class for my bike, but tried to support them. Looks like they don't even have a schedule for 2016-

Most of the guys I know with race bikes aren't racing, sold them, or are trying to sell them.


East Coast guys should thank their lucky stars for the AMRA-
Keepin' Harley Drags alive and kickin'!

the brownes didn't build it for any class,they just wanted to see what they could do with a turbo for their own satisfaction.it is probabley the finest engineered HD drag bike running now.bar none (& dana`s bike wouldn't have a chance with this bike).kieth & pete browne have always had VERY bad ass turbo bikes when the did run in a "class",(7.40`s out of a 88" turbo gas shovel in the 1990`s) they have nothing to prove to anyone but themselves

it got kinda ugly for no reason.there isn't really a class that the bike fits in.
IMO the Browne's listened to the wrong people tell them how they though it was gonna be.
gotta be Nitro to run funny bike /dosent have to run nitro to run funny bike/just put a drop of nitro in it to run funny bike....bla bla bla. they should have just called and talked to Marty first. some funny bike guys want them torun  some don't. :nix:
IDK and don't have a dog in the hunt. I like power adders nos EFI and like to see the bike run. I hope it all works out for everyone.
