Eight Pounds and 40 Stone Build

[bonneblktrk]

Thanks.
I used the overall diameter of the tire to get wheel height. Seems pretty level to me but didn't check with a level. Think ground clearance is taller than stock, want it a little taller than stock, don't know how much. Ride height can still be adjusted with rear shock placement and shortening fork extensions.

On driveshaft, not shortening just adapting the rear spline of the differential to the gl1000 shaft.

Started machining the pivot pieces. Also ordered the new swingarm bearings from Wingovations.com in the UK, the new style kit with the thrust bearings. Looks like a good setup and didn't cost much more than just 2 bearings from oem sources. Going to wait for bearings to finalize the bearing holders I am machining.

This build is looking to be epic. Beutiful machine work. Looking foward to following along.

Hey thanks man, appericate it. If you are interested in machining processes...was the same on both swingarm assembly mounting blocks.

Nice metal work!!!!

Thanks

wow, this looks like a great story to keep following.

I love the work and the speed you are working! (wish I could find that much spare time.... but that will come back once my son's have the age to come help me (if they want to....))

Hey thanks, I like what you are doing to. I'm semi-retired, focused/obsessed, and delay working on the home-improvement projects my wife would like. Motorcycles are so much fun to work on!

I don't recall if it was asked, but are you planning on doing any beefing up of the engine internals to cope with the supercharger?

[bonneblktrk]

Haven't gotten that far yet. What would you guys suggest. I know when we put a turbo on my son's Civic it stretched the head bolts and had to replace with ARP bolts. But that was with 12-16 boost.

[wingrider]

I guess it depends on how much boost you are planning on running, and if you plan on pushing it to its outer limits. When they did the production of superchargers back in the 80's, I'm guessing not to many people opened up the engines...they popped the kit on, and took off. I honestly don't know how much boost they were making with said kit. I am guessing that info wouldn't be to tough to get.

When I had planned on going with my dual supercharger build, I had planned on making sure the bearings couldn't spin, and had looked into copper head gaskets. I was planning on running about 5-6 pounds of boost. Now that I am just going to give her a small shot of Nitrous, I figure I'll still stick the bearings, (being the engine is apart) but run stock head gaskets, and look for head studs vs bolts.

[bonneblktrk]

Maybe 4-6 pounds. Will help some and mostly doing it for the process, looks, and simplify the carburation. I mean how much can you really get out of these motors, 100 HP more?

I'll still stick the bearing

What do you mean with that.

[Red2trike]

I would suggest a e-mail/phone call to Randaak for info about supercharger elements as he has more than enough experience (both centrifical/turbo) and set-up details to help you. Most of those CCI set-ups ran 3-5 lbs boost and added about 50HP to the GL1100 motors. For the most part these "kits" were bolt-on with no more than stock pieces (bolts/nuts,etc). Again, asking Randaak is best.

I ran a street supercharger on one vehicle (factory stock) and over that time period learned what NOT to do. Later, I was re-building a car and wanted to increase the HP and was thinking about supercharging. Never got the supercharger part project started...but did investigate what was needed and would it stay together. Racing people I talked too thought it a very dependable set-up as I wasn't getting to crazy with the set-up. But I talked about O-ringing (copper wire added to metal head gasket) and bolt-in studs for the head (like others do). I was upping CR to 9:5 from 8:1 and using stock head components (valve size, springs, etc) and not much more than fitting exhaust gasket to port shape/size. Nothing more on heads. Otherwise very stock and simple, but with a 5-lb boost Paxton blower HP was increased by about 50-65. And that was running 87 regular gas from the pump. Just giving you what I had planned and would work with little or no problems running on the street. Just K.I.S.S.

What do you mean with that.

There are a few folks that have had issues with spinning some bearings with the use of additional power products...so I originally planned on pinning the bearings, but when asked about it, I was informed that you don't use pins in this day and age, you use Loctite 271 (or equivalent) Stud n' bearing fit. Essentially, you glue the bearings to their respected surface, so they can't move.

As far as how much power...I would guess somewhere around 100hp is about it till you really need to change parts in the engine. When looking at how much boost I was going to run, 5 pounds was going to get roughly 40 hp. Could have been slightly more or less.

I had emailed Randakk about doing the superchargers, and he recommended a book to me. It is written by Joe Haile, and is titled "Motorcycle Turbocharging, Supercharging, & Nitrous Oxide." It is no longer in production, but gives you a pretty good idea of what needs to be done in order to run a power enhancer.

Thanks for the info. I will research the book.
