Can anyone help me purchase or obtain plans for a model V8 engine, this is for my own personal use in model boats.
Coles has the Challenger
http://www.colespowermodels.com/engines.htm
There are plans on most of the Yahoo engine groups for the Amsbury and Whittle V8.
What size boat are you building? The Challenger is a 1/4 scale and would be a bit heavy.
I am currently making plans for a 5/8 bore and stroke V8 that is about 1/5 scale. The block is just short of 5 inches long. This way i can build it on my small mill and lathe. I will make the plans available but it wont be for a while.
I tried the link to the Amsbury V8 I posted a year ago and it is dead.
As I have all 7 of the PDFs, I have posted them below and compressed the ones over 500k into one zipped file.
The system would not accept all seven files zipped together for some reason.
You might try searching Yahoo Groups. Some require that you join to recieve free plans.
I just recently purchased the Coles Challenger V8 castings and drawings and quickly realized that this is not want I want. I am not pleased with the location of the exhaust ports/manifold.
I've searched and found several sites with really great looking and performing motors including the Conley web site. The Conley Stinger 609 looks and performs well but has a 1 year lead time with a price tag of $5300.00 Conley only sells the engines as complete running motors and not in kit form. I want to build my motor!
I would like to purchase plans for a V8 made from billet aluminum so I can machine the parts and assembly it.
If anyone could point me in the right direction, it would be greatly appreciated.
Thanks.
That Amsbury V8 posted earlier can be made from billet aluminium. You just have to think about it for a while, because the original was made from brass plate soldered together.
Jones,
Thanks for the suggestion. I did look at the PDFs of the Amsbury V8 and felt that it would not fit well into my current project. I will look at the Amsbury V8 again.
I prefer the following style V8 (but without the blower)

Thanks.
I have rang and ordered the plans for the Schillings V8 not an easy task as there english is not to good, bad actually. But looking forward to the plans.
Bevan,
I found the link to where you can purchase the Schillings V8 plans.
http://www.vth.de/shop/warenkorb/art...ash=8407db4a24
The site is in German, but I did email them about purchasing the plans. While searching the site, I also found a link to a book Hubert Schillings published in 2001
http://www.vth.de/shop/warenkorb/art...ash=d6b2283613
From what I read, this book has lots of good information and pictures on model building.
A billet motor is the way to go i belive but you need to think about cooling, air cooling is the simplest form in a billet engine but watercooling is also possible if you have a bright mind :)
Adaware,
If you know of anyone selling billet V8 plans, please forward that information. I've done an extensive search and email many of the builders (who’s links were posted earlier) but have had no response yet.
Sorry, don't know of anyone that sell such plans. I'm working on a billet v8 engine drawing myself but each time i fit a new component in the engine it's like opening a can of worms because of the scale and all the parts that needs to be there :)
Where are you at with the drawings?
I am working on the heads of a V8 project. The current design only allows a 8-32 sparkplug.
The block, crank, rods, pistons, camshaft are all done. I need to get the heads done before i move on to the intake manifold.
It will be 5/8 X 5/8 bore and stroke.
My engine will be a giant compared to yours :)
What does 8-32 plug mean, 1/8" with 32 threads pr inch?
I first wanted to use the CM-6 from NGK but now i have changed the plans to ME-8 or similiar plug because i couldn't find room for the valves, the idea is to make shure an off the shelve plug fits and then make them myself since they are so expensive.
I currently have a bore of 40mm and a stroke of 30mm so it's about 1:2.5. Have had many 3D models finished but i have redesigned the thing so many times they are not correct anymore so i need to redraw them.
Woah, that will make an engine of 301.584cc !!!
I want to make, in the distant future, a 4 or 6 cylinder inline engine of about 400cc-500cc capacity. Nothing flash; probably a pushrod operated, 2 valve per cylinder engine with dry sump and water cooling. I like to make engines which I can actually use for something, rather than just display models (though I enjoy the display ones as well, just not as much)
Why such a large bore to stroke ratio?
Your not from around here are you?
#8 thread has a major diameter of 4.16mm and 32 threads per inch. There are vendors at the model engine shows that have plugs that start at 10-32 but 1/4-32 is most popular. You are correct about the money. They are almost 20USD each and the 1/4's are 12USD
#10 = 4.82mm
1/4 = 6.35mm
The picture below is a 1/4-32 next to a production NGK.
The bore stroke ratio just came by it's own when i found out how big the combustion chamber would be. I plan to make a kind of racing style type engine so the short stroke is not so bad.
I'm from Norway so i'm not so familiar with the inch system as i am with the metric but i guess both systems works well as long as you know both :)
I will start my own forum thread of my engine project when i have more completed drawings and have the tooling to make the parts.
I have ordered the plans for the Schillings V8 motor from the web site in Germany and will post them on here when i recieve them.
I just order my Schillings V8 engine plans and the Schillings book (published in 2001) from the German site on Friday. Expect they will be in within 2 weeks.
Hi,
i'm trying to get a plan for a mini V-8. Can anyone help me.
My project in to build a big RC boat and i was thinking that a V-8 will look awesome in it.
Can someone please let me know if they are ready to pass me their plans.
Thanks.
To Mike GT40
Have you received your V8 plans for the Shilling engine for vth.
I have tried to purchase the plans with no luck due to the site being all German.
How did you order the plans.
Allan Roberts

Hi Tony, i am interested in your parts for sale, sent you an email.

Cheers Mick
Could someone please explain or give us a link to a site that explains thread numbers? I grew up with Imperial threads but that was 30 years ago. Adaware asked the question but the answer by stevehuckss396 just gives the metric equivalent but doesn’t really explain it (no criticism meant). I’ve just spent nearly an hour looking for the answer but with no luck. I googled it but it seems that computing and internet threads take precedence over physical threads.
I realise the last number is the threads per inch but what do the first numbers mean? (eg: #8 or #10) Is it like gauge numbers where the smaller the number the bigger the size? I looked at gauge numbers but they don’t seem to line up with “#10 = 4.82mm” so I really don’t have a clue.... Does this relate to all (american) threads or only Spark plug threads? I even checked out NGK's web site but found no help.
thanks in advance.
Allan, pm me your email so i can send the plans.
Engine is 4 1/4" long
Mick
See if this helps.

A number zero screw has a shank diameter of 0.060"
Each screw number larger increases the shank diameter by 0.013", up through #12. After #6, there are generally no odd numbers.

Thanks guys! This place is awesome for the body of knowledge of its members. The bit of info I was missing can be summarized by:
The thread numbering system is a system that fills the gap for all imperial (inch) threads under the 1/4" size. #12 being the first size under 1/4" and #0 (probably) being the smallest on offer. The second number being the TPI and the first number being just an assigned number with (as Tom said) each screw number larger increases the shank diameter by 0.013", up through #12. After #6, there are generally no odd numbers.
Once again, thanks guys!
Hi Mick

Hi Mick
Have you sent the plans for the V8

Another fine looking machine in the making!
Looks large, or is the table small?
It's a bar stool. The head is 4.534 inches long

Beautiful work, Steve. Is this done on a CNC mill?
Are you going to use ball bearings for the two end crank bearings?
