Re: 1936 92 ci VL

The bike started as a chopper, then I got this bright idea . The forks will be changed and the fork angle modified to 5" trail, foot pegs moved to rear , handle bars lowered. I am familiar with what is needed for land speed racing, after 25 years of drag racing in 2011 I built a shovel head and took it to Bonneville in 2012 we took it to the Texas mile , best yet has been 161 running way rich. Thank you for your concerns , all comments and criticism's are appreciated they help to make a better machine.-----Turk--born 1936 same as the VL P.S. Yes, I built it , I ride it

Re: 1936 92 ci VL

....that's what was puzzling me. Does this engine have a racing history, then? Or is it a completely new project?

Re: 1936 92 ci VL

The motor I acquired in 1972 with a bunch of VL stuff , I didn't care much about it at the time so I put it on top of my mailbox for decoration it was on there For over 40 years until 2010 I decided to see if I could make it run. Didn't have any rods , flywheels , pistons,cams. So I used late rods T&O wheels and found or made the rest. The bike was completed in three months and ready to ride with a 92 cubic inch VL motor in 2010. It was four weeks ago that I discovered two blowers off of Buick v6's and got this bright idea and thought I would see if it would work. I read Panics paper on blowers and decided to try it. I was well into it and about finished and decided to discuss it with Jeff, he straightened me out on a few things, got me on the right track. It is up and running and pulls like Jack the bear. I'm used to riding race bikes and this thing is about half scary, but I'm getting kind of old.

Re: 1936 92 ci VL

where do you live, that you can have a VL motor on top of your mailbox for 40 years? It wouldn't last 40 minutes round my way before the pikeys had it away... come to that I wouldn't give much for its chances of running again after 40 years in MY front yard.

How long does it run an a total loss ignition system? My grasstrack bikes all have magnetos these days, or some sort of bump-and-go system because I got fed up with running out of sparks halfway through a meeting. I once had a BSA Bantam that ran off a battery ( dead charging coil ) and it used to run for about half an hour.

I was provoked. By the site of that unrideable thing.and to race it, even more dangerous! Put the motor in a decent frame and no more provocation.

That is a poor definition of provoked. With bikes it is as to each his own preference. Why not just say it is not your bag or cup of tea ? Why blast a person for their likes and dislikes ? You've been around here for quite a spell. You've been a fairly good member as well during that time. Must be something else bugging you because you don't come off the way you did towards a fellow member as you did this time around. I sure hope what is chawing at you subsides soon. Mellow out.

Re: 1936 92 ci VL

Blowers and turbos on a bike have never been my cup of tea, mostly because they just don't fit in anywhere...always sticking out someplace. However, forced air does make sense to me on an engine that does not breathe well normally. (flathead) I would think that a sidevavle would benifit most from forced air. I'd like to run a turbo on my '48 Dodge, as it would all hide under the hood. But, it just runs too well as is (dual B&B's) to mess with it. !!

Anyhow, to each their own, but I can appreciate it.

Back in the 60s, I remember seeing some very tidy supercharger mounts on Triumph 650s, but I have no idea how they performed or better yet, how long they performed.

supercharged 650cc Triumphs were used in grasstrack racing in the 60s, and of course drag racing http://www.theaccelerationarchive.co.uk ... ps_03.html

Re: 1936 92 ci VL

That was quite some reading.

I've often thought that a turbo might be ideal for a flathead, since most long stroke flatties produce lots of low end torque, then kind of runs out of steam as the RPM's increase. Seems like the turbo ( with it's lag) would start turning on about at that time, and would be a good combination. ?? That's why I've always thought that a small turbo off a four cylinder would work well on the flat six in my Dodge.

Having said that, I guess super charging adds power throughout the power band, so maybe it's better.

Re: 1936 92 ci VL

my guess would be that mechanical supercharging would be preferable for flatheads because of the "turbo lag" effect. I would guess that a turbo-charged flathead would do well enough as a drag bike but not on the road. isn't there a turbo-charged 45 that has appeared at Maxton? Maybe someone who has tried it, would comment?

Re: 1936 92 ci VL

But don't you think that the flathead would be producing plenty of torque while the turbo was lagging, and then the turbo would kick in about the time the engine wasn't producing any increase in torque? I'm not sure where peak torque occurs with the Harley flathead, but with the Dodge it's very low in the RPM range, then you feel the engine kind of run out of "steam" as the RPM's build/increase. That's how it seems it would work to me...but I don't know. Just spit balling here!

And....are those aluminum heads that sat on top of that mailbox for 20 years??? !!!!

Re: 1936 92 ci VL

I'm thinking mainly of the effects on controllability and rideabikity. There were some very effective supercharged solos built in the late 1930s for road racing - they were remitted at the time - and I think that would be the direction to follow. BMW in articular had a very effective flat twin in that frm.

Re: 1936 92 ci VL

Yes, I'm a bit of a BMW fan, and own one, and they did indeed have some success with super chargers...the flat-twin design/layout kind of lends itself to mounting a blower on the front of the engine a little better than a V-twin or even a vertical twin.

I still want to know if a set of aluminum heads sat on that mail box, unmolested, for 20 years. !!!!!

Re: 1936 92 ci VL

They are iron, and corroded, but good inside, probably will get new alum ones .
