What modifications are made to pro-stock bikes? Are they normally aspirated?

Only less so. I saw a mag article on this bike. NASCAR (the "S" is for "Stock", BTW) cars at least use motors based on actual production engines. The engine in this bike shares only its basic layout (60-degree V-twin) with the V-Rod. If memory serves, it's a 2600 cc pushrod motor.

Congrats to them, I'm sure they deserve it, but....



I know these bikes (all in the class) are modified to hell and back. It would be kool to get a write up on the bike, crew, racers, etc. Including a description of all the mods the bike gets (and maybe a primer on the rulles of the class, for those who don't follow drag bikes)



Just a sugestion to the kind folks at MO. See what you can do. Any story/interview/information on the racing world is usually an interesting one.

Some of the bikes in this class are closer to stock than others.



H-D was given extra leeway to mod like mad compared to the other teams in this class. Most of the guys are running weird Suzuki blocks that are bored out, etc...



The H-D isn't even a H-D. Probably not a single H-D part on it. It's a 2.7 liter pushrod V-Twin that Vance and Hines carved out of a single block of Billet. It's Air cooled or not cooled, like a top fuel motor.



This is even more strange than the crazy Buell mods allowed, as the V-Rod if placed in the right competition would certainly be competitive close to stock.

I'm sure it'll be a cold day in hell before a race team spill the beans about what they've done to an engine.

Dale Walker @ Holeshot Performance is pretty involved in drag racing, and has some cool old photo's and what-not, though his focus is on Suzuki Bandit's, not Harley.

You Don't Follow Bike Drag Racing, Do You?

If you did, you would know that NONE of the bikes are even remotely similar to their street counterpart. Just admit it, you just can't stand that HD is winning anything. On top of that, it has had a boat load of weight added to it to give the aging other designs a chance.....gice a break. The only thing the Big 4 bikes have in common with their street namesakes is the number of wheels and cylinders, just like the HD....

Re: You Don't Follow Bike Drag Racing, Do You?

James, you are correct on the level of mods on ALL of the bikes in the class. However, aside from name, the only thing Harley-Davidson about that V-Rod is the check that pays for the effort.

Vance & Hines designed, built and operate this VRod. V&H have been winners in almost every class they have ever raced in, including Pro Stock & Top Fuel Dragracing with Suzuki and recently HD, as well as in AMA Superbike with Yamaha and Ducati. -Sean

Enough already.

Will someone please change the main photo on the home page to something else besides the chick flipping the finger?

*gasp* But I thought that when you went to the Big4 dealer and bought a race replica you were getting the same thing they run on the track! The boys at the Burger Barn are gonna really cry now.

But they race they monty carlo- and mine won't do a buck-eighty - waaaaa!!!

Sorry to give you the wrong impression. I'm not looking for blueprints and motor secrets of a custom drag bike. I said that a story on the team/riders/bike-modifications would be an interesting story for MO to persue.

Plus I have never seen the specs for the V&H drag bike they are curently racing. While not a big follower of the drag race scene, I like reading about all types of race modified bikes.

And again congrats to them for wining.

Re: You Don't Follow Bike Drag Racing, Do You?

Didn't Vance & Hines get Suzuki to produce cast-iron inner cases for the old 1100 GS series (T.S.C.C.)?

Too much nitro, or a stuck wastegate, and boom. Aluminum everywhere.

Much like BMW/Renault using all cast iron blocks for getting 1500 qualifying horsepower from F1 cars (when the formula called for turbocharged 1500cc engines). I think they were running 7 bar.

Re: Enough already.

I had that on the screen yesterday when our corporate enviromental ginch and her EPA associate came in wanting to see my combustion analysis records for some of the boilers I run

I could tell they were not amused.
