John here, im in australia and design/supply/produce small engine parts such as superchargers/turbochargers/pulleys etc.
Just got my hands on a 14hp briggs vtwin which i plan to use for producing some performance parts.
I see that they are pretty popular in USA and do some crazy things with these type of engines.
We dont see too many of these engines here and would like to know if the 14hp vtwin shares the same intake manifold with
other larger units?. Also, are vertical shaft engines as popular as the horizontal ones?.

Hi John. Welcome to ATLTF. The Horizontal shaft motors are more pupular with karters and high speed Tractor guys. The vertical shaft motors are more popular with tractors and guys like us on here.

I don't know about the 14hp twin. I'm a 12hp flatty guy only so far.  Cool

To find out about the intake, I would go to a parts look-up for briggs motors and enter your model number then look at a diagram for another briggs and see if the part numbers match.

Not true, verticals are extremely common in racing. Horizontals are pretty common here...

Why not look into a turbo, seems to be much easier to hook up.

Yeah now that I think about it your way lol. But I haven't seen horizontals do any real high performance on here, just mostly stock.

Welcome to ATLTF John. Regardless of what is popular in racing, it is irrelevant, anyhow. I have not heard of a sanctioning body or a racing class that allows forced induction.

If you were to concentrate on an specific architecture, I'd suggest the horizontals. They tend to appear on the more capable tractor designs in stock form, and I am betting you'd have a more receptive audience with them.

Now- since there's not really a lot of difference between similar horizontal and vertical shaft engines, (especially once you remove the governor from the equation), I imagine it wouldn't be hard to adapt from one to the other.

I have 30years experience with both blowers and turbos, i may look at doing turbo but going turbo means more expense. Blowers lot easier to setup for the average diy blokes.
If i do a turbo setup i'll use a IHI RHB31 Z21 turbo and maybe my recently acquired motorcycle efi kit.
I have been talking with my mates in china about retro fiittng carbon seals into some of the smaller turbos for draw-thru carby setups.

Look at some snowmobile turbos like polaris and artic cat. they got some great turbos for this, just gotta make manifolds and a oiling system. Probably would help alot if you have pressure lube

Welcome

This is of a major interest to me and would love to work out a collaboration in the future to help both of us. I run a youtube channel called Redneckcomptergeek (2nd largest mud mower channel on youtube)
https://www.youtube.com/user/redneckcomputergeak

The old school will tell you flat heads are the thing. To be fare they are great engines but they are dieing off this is why i run 15.5 or better ohv's but am soon to switch to a newer intek because this is were the market is going.

the secound thing i would like to point out is most of us stick to singles because they are cheaper and weigh less. Many of the guys that run 18 twins and vtwins have problems with the weight driving the front tires down.

I'm normally only on this forum a few times a weak so feel free to PM me if you have a question or need help with an idea or part info.

Sincerely
Fellow good old boy.

Oh there are some here that know HOW. Mowbandit has actually built a supercharged oppy. I've huffed and blown a LOT of cars over the years. The problem is money. Most of the kids on here can't swing that kinda credit bat. I could afford one if I didn't feed the critters for a month... LOL

You could build a honda gx200 turbo or supercharger which might appeal to the entire go kart community
