Guess which bike is quicker??? : V-Twin Forum: Harley Davidson Forums

merc1100sc · 07-14-2008, 10:33 AM

I've got two buds w/ built bikes that have joked have wanted to put the bikes up against each other for almost a year now but just never seemed to be in the same place at the same time.
This past Saturday we finally ran them. heres some info on the bikes:

1) 2006 night train. 124" (NO Balancers) R&R cast heads w/ some extra massaging & larger (not sure of the size) intake valves from R&R. R&R 62H cam, 55mm tb, primo clutch, stock gearing, stock 200 rear tire. Bike was just tuned last week by Performance Harley out of Syracuse, NY. Rev limited @ 6200. Made 145/145 w/ a very nice torque curve. Rider goes about 155 pounds and knows how to put it down.

2) 2003 V Rod. 1350 Stroker motor built by Eagle HD out of Indiana, I believe. Stock gearing. 240mm rear tire. Bike was tuned last year by Joe's Cycle in Mechanicville and made 143/100. Rev limiter set @ 10,000. I rode this one. I'm 165 and my left foot seems to work ok..........

we did a dead stop start 1/4 run a couple times and a few roll on's from 20mph. Guesstimate the results.............

Since everyone else is just looking and not voicing there choice here's mine...My vote is the V-Rod...

BMoscato · 07-14-2008, 11:12 AM

Agree with 1711tab. VROD

TXCHOP · 07-14-2008, 11:18 AM

My Votes for the 145/145 124 softail. With the 200 rear tire is should be sticking o.k. and the tq early on might have gave it and advantage to carry him down the track.

Then again, lets hear some more about this stroked v-rod...

merc1100sc · 07-14-2008, 11:36 AM

Heres the Vrod.

Stock 03 "A" model w/ a Falicon crank, ported stock heads, megacycles cams, stock t/b's, rineharts. I dont know much about Vrods but i guess Eagle HD is one of the better shops when it comes to them...

BAGN1T · 07-14-2008, 11:41 AM

I vote Vrod

kdietz · 07-14-2008, 11:49 AM

I'll take the loser

merc1100sc · 07-14-2008, 11:58 AM

The Vrod every time.

They both spin a bit off the line.

from a roll from say 20 they are pretty even til the top of 2nd on the vrod then it starts walking away pretty good.

And thats w/ a clutch that's slipping pretty bad. cracking the throttle at 4K in 2nd the revs jump right to 9K and hold there until the bike finally catches up.

I was actually surprised. I thought the brute torque of the TC would jump out ahead and the vrod would slowly track it down w/ the higher revs......

Colonel Sanders · 07-14-2008, 12:27 PM

The V-rod is staying in the power more with it's 10,000 RPM rev limit. Look what RPM it drops down to on the shifts and what power it's still making at that point. Now, look how far the TC engine falls on the shift and look what power it's making at that point.

BTW, 6200 RPM is WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY too low of a rev limit for that build. For example, my 124" (a milder build than the one you're talking about) makes peak HP at 5950. So what shift RPM would you think would be optimum in a drag race? Well, with my 5 speed tranny (wide gap between gears) it's higher than you might think. I'm making a peak of 134 HP SAE but I'm still making about 130 at 6500. My RPMs fall back about 1500 on the shifts. Even if I shift at 6500, a full 550 RPM after my HP peak, my HP is only 125 HP in the next gear. So, even 6500 isn't high enough. Probably more like 6700 would be perfect for this combo.

See my point? I have S&S 640 cams. The 62Hs are higher revving cams than mine. I bet the 145 HP came right at the limiter? I wouldn't be surprised if it made a few more ponies a couple of hundred RPM higher.

Set the rev limit on 6900-7100 and try again (if you think she'll hold!) I bet the V-Rod still wins but it'll be a closer race.

merc1100sc · 07-14-2008, 12:58 PM

Maybe its the 62T. I'm not sure to be honest. I'm pretty sure the motor is done before 6200 though if I remember the dyno sheet. Not too mention I dont think he'd trust revving it too much higher than that.

Damn I like being RIGHT...

claydbal · 07-14-2008, 04:51 PM

yalll reckon a sliiping clutch that eventually grabs is helping the vrod to launch and keep at peak through the gears?

i was gonna guess the 124 would light up off the line and in second as the vrod bogged then got into the power. 124 torquing through mid track with vrod running hin down towards the end.

a vrod with that build and a guy that knows how to launch it (with good clutch)and shift points should be into the mid 9's. the 124 the early 11's, maybe----late 10's

Hey, I certainly don't blame a guy for not wanting to rev the piss out of it (I have my limiter set at only 6400), I'm just suggesting that the bike wasn't being driven to it's potential if it was shifted at, or even close to, the HP peak.

Either of those cams should peak higher than mine (more duration and a later IC) so I'm wondering what's up with that if it's peaking at only 6000.

Colonel Sanders · 07-14-2008, 04:53 PM

The TC TQ advantage means nothing after 1st gear....and means nothing but more tire smoke in 1st!

oh1deuce · 07-14-2008, 07:02 PM

Is 145/100 good for that much work on the V-Rod? The Rinehart's must be killing it.

What's the compression on the V-Rod?

Yes the rev limiter on the Train is for sure too low if they yanked the balancers.
