These machines are indeed quite a different breed of cat vs. conventional Harley powerplants.
They seem to repond very nicely to changes. The folks at Megacycle with their extensive library of cams have been very helpful to us with our customers. Able to generate some stout power from these.
Very interesting to work on.

Otto and I are looking for a cheap wrecked VRod, one that the engine is still good in. We're thinking about making another drag bike, custom frame from Weekend using that motor, race prepped and increased to 95 cu. in. and then stepped on hard with NOS. We think that would be a hoot! Prolly have to run it in the Pro Gas class but what the -hell- !

Tote,
I bet that SOB would really rip! Gary Stroud used to run the laughing gas on his bikes.(not V-Rods) His folks had a dealership in Valiprasio, Ind.
We did 2,(no bottle) back to back with 88" kits that marked 162-165 hp and 110-112 ft/lbs. Our heads, Megacycle cams, D&D Fatcats and tuned @ Joe's. Go to Eagle H-D In Layfaette, Ind. as they know the shortcomings of the liners that Wiseco/Zippers offered, and will bore the cases accordingly. Long, bad, story on the Wiseco/Zippers set-up. That combo was never R&D'd. Just thrown togather to reap profits.

Hi Scott,
My understanding is that due to design geometry with the stock cases that 95" is the displacement limit on that motor. We would consider not using liquid cooling as the motor will only run for 1 min at a time. We would look for the best possible bottom end components to handle the load and we would use "real" race pistons (with coatings) and "real" race cylinders. I haven't looked into the heads yet to see what we would need there, so that could be interesting. What intrigues us is the ability to use the injection and that lends itself to using NOS. We also think a 95" Revolution motor on the juice in a real race chassis would be a lot of fun AND it would be different.

Last weekend, the most competitive PG bikes were running 7.8's, don't know if we could get there with this combination or not.

Maybe SuperKaz will chime in on his thoughts.

Fun to think about!

All the best!

V-Rod Kit · 03-30-2007, 05:14 PM

there are a couple of v-rods running naturally aspirated in the mid 8 second range...7.8's with N2O might be achievable if you can get the cases to hold together, that seems to be the new weak point that have found but i believe the BADROD was pushing ~200RWHP and had a season of racing before the cases let go.

lot's of good info on drag racing v-rods can be found at www.1130cc.com FWIW

great..... cases are the weak link. <rollz eyes>

we'll have to look inside and see if a girdle or some such can be adapted before we invest real dollars.

thanks for the input.

Eagle offers studs instead of bolts to help keep the cases from migrating.(not popping apart though)

Otto · 04-15-2007, 11:26 AM

would still like to "play" with one and would like to see where they broke hey put even wrecked ones are not cheap enough. but it would be interesting

is FALICON still around? they used to be in the know for case strenghtening/ crank integrity issues.

sportking · 04-15-2007, 11:53 PM

Falicon is alive and well . They just done a crank for my buddys Busa !

They make stroker wheels for the V-rod.

I have a buddy that did a big bore from 1130 to 1340cc on the v-rod and is getting 150 rwhp, not too shabby. Not sure how many cubic inches 1340 is, I know 1130cc is 69 cu in. It is not really a pro gas dragster, but he is running in the 9 second range on the 1/4 mile. He isn't the best rider and is having trouble launching the damn thing, it either wants to come up on him or just rip the back tire off. He is thinking about adding some NO2 next to see if he can spray it once he has it launched and get another .5 out of it and get into the 8 seconds. Right now he is racing some of the 4 cylinder metric sport bikes and beating them, which is great to see. It is very streetable and you would never now it isn't stock when looking at it or hearing it run. Very dependable as well.

YankeeBob · 01-11-2008, 08:22 AM

Isn't the EVO a 1340? And if it is, isn't it 80 ci?

The Eagle/Diener built Badrod2. lasted all of 3 runs at the event it ran in the 8's And has since been heard from. Reliability was a issue for the all motor 8 second VRod.
The street ridden Blackcat motorsports VRod equipped with its 2 ring wiesco bigbore kit, and internals by Falicon. Has run in the eights and is on there 3 season!
Did somebody mention cro-moly chassis VRod?
