Lightened Flywheel

[DeathBySnuSnu]

Hey Mo Lee:
I here ya brother. It was the late 70,s to early 80,s that I got into my vee dub.
The first motor I really tore up was a 1500 single port with a slip in big bore kit. I think it made it around a 1600. With a 2 bbl holley bug spray carb and a big cam. I pulled the flywheel one day and chucked it up and cut a lot of wieght off the flywheel. I have no idea how much, I was only 16 or so and just learning so I was trying stuff. The flywheel didnt do a whole lot with the stock stroke/crank. So I found a Ray Jay turbo and built a header and put the carb in a can. I have no idea how much boost (manually adjusted waste gate). But it was not a lot anyway (small turbo).

I kept turning up the boost and was starting to get significant gains happening.... then blew a head off of it. Pulled the head studs out of the case. After this I started building stroker motors and never messed with a turbo (on a vee dub) again. The stroker cranks all are 8 pin that I have seen. This trike I have actually is my old hot rod sedan that was a wheel toter. I cammed it down and shimmed the jugs out and did some major re-gearing. It has some long legs and still sprints like a hot motorcycle. One of the rideing buddies has a v-rod (Harley crotch rocket) with pipes and a computer re-tune. He likes to gas on it hard.

He giggles every time he leaves all the other guys behind exept me staying right behind him on a trike. I can not in any way get around him but no matter how hard he gasses on it I am right behind him, He thinks it silly that a trike keeps up with him. It makes me giggle to do it too......LOL But I am getting old and a lot of this hot rod stuff is getting out of my system.

:Coffee...Just by listening , I don't know if it's out of your system or not . Once a hot rodder always a hot rodder . .. My favorite place to ride is down your way ,via the Trace , ever get that thing up there? Maybe one day when were down there we can get together and you can show us around ......

[DeathBySnuSnu]

Sure.
I am just a little bit off the trace. Not unusual for me to ride between Ratliffs ferry and Port Gibson. Most anytime when the wife is willing to ride (it aint her thing) we ride the trace. Catch it just south of Vicksburg just round the corner from home and go to Jackson to eat and back again. She is scared of the hiway on the scooter. But most anything hot rod is gone now. Used to have a 440 'Cuda among other things.
I work a lot, being part owner of a shop and all, so give me a heads up first. I will try to be available. I have never gotten the chance to scoot down the road with a fellow vee dub triker.

Thanks, guys, for all the help and info! As always, I go away learning something and on a little bit straighter path. To be honest, I didn't realize the veedub motors had so much potential as far as non-factory set-ups like the FI and distro-less ignition systems. I always viewed them as somewhat limited in that regard. Lookin' at it in bit different light...

[skuuter]

I ride down to Leipers Fork, Tennessee, and the Natchez Trace from there to Lawrenceburg, Tennessee or Florence, Alabama fairly often....a really good riding area.....

[slick rick]

Yep skuut ,,...., the wife and I rode up to Franklin one weekend picked up the Trace and rode it to the end and on in to La........ That's just seems to be the most peaceful place I have ever ridden .We're planning another if we can get a weekend without rain , maybe or just carry rain suits before the summer is over .

I think this link will work.....
Rapping on a light flywheel.

If your using a stock crank I wouldn't use a light flywheel you will loose bottom and mid range power. On cams I like Engle VZ14,15, & 25 cams very wide power band. I have used these cams on 1600 to 2332.

That is what I experienced with mine also when using a stock crank.

I am running a cam for high ratio rockers.
.560 at valve , 314 adv duration, 107 lobe center.

You can tell it has a low end flat before the cam comes in. But I am light enough that you never notice it, have to bog it and hunt for flat spot. And that is with 3.44 r&p.

That's a big cam. Are you using big valve dual port heads and dual carbs.

[DeathBySnuSnu]

Yes.

050 cnc d-port with 42 in and 37.5 out ss valves. Heads are machined to take that much lift. With duel 44's. Collecting the parts to go fuel injection and dizzy less now.

Your not running a fan shroud. Also its looks like your legs have to go over the air filters. Going mid engine makes it handle better but I would like to use a automatic trans. I think you can flip the ring gear on a auto-stick trans. Problem is I haven't seen a auto-stick trans or car in years.

[DeathBySnuSnu]

No problem idling through a red light. Cools just like any other air cooled motorcycle, Harley for example. You HAVE to go for it to cool.
I have only ever seen one auto stick (in person) my entire life. But from what I hear you can flip the ring. My ring is not flipped, my entire tranny is flipped. Took some internal machine work on the oiling. Just did not want to run a stroker on the coast side of the teeth.
Took a few measurements and did the math, very crudely, assumed 50 mph wind at 100 deg. It looked like I would run out of cooling at a continuous 80HP output at this point. Yes it was crude numbers, but I don't think I ever run that much continuous HP. Yes I burst way more than that. But at highway speed maybe 20 hp cont? So as long as I don't pull a 2000 lb trailer uphill all day I should be good.

Legs beside Carbs.
