Briggs OHV & Vanguard / Re: 21hp vanguard camshaft
« on: September 10, 2017, 06:44:56 PM »
if i remember right the 38 cam (20hp vanguards have it also) has .01" more lobe lift .030 roughly valve lift.... but like i said its been a while. Depends on your rules but for pulling simple stuff like a steel flywheel, more compression, timing and a good carb should help

Briggs OHV & Vanguard / Re: 16hp vtwin vanguard head work

Are you wanting to put 30ci heads on a 30ci engine? Dont waste your time, you may turn 9000 rpm with 30ci heads but you wont be making power. Build 38ci heads with the far superior port design. For a 30ci 33-27.5 valves and a nice port job will do very well but for bigger engines and more hp we have 1.450-1.200 valve heads with a lot of port work will make a ton of hp and put an engine at a national level. Here are three options you can buy off the shelf.

The biggest air flow restriction on the 21-23hp engines is the intake itself. Even with mild 33-27.5 ported heads the intake ports will greatly out flow the intake. The only way to make decent power with stock parts is to extrusion hone the intake to get around 110 cfm. Cromwell race engines can do that for you. If you want big hp then you need to discard that and make a custom intake or dual intakes for dual carbs. Hope this helps.

Chassis chassis and chassis again. If you have a properly setup chassis then 6" is the way to go in my opinion. Thats coming frome someone who has run both. Plus you can afford to have more sets of 6" vs 8" price wise

Briggs OHV & Vanguard / Carrier performance new website!

After a lot of thinking we have decided to make a website to buy high performance V twin stuff. No one sells stuff to help people build national competitive engines so we decided to offer high Horsepower parts. Here is our new website, browse our parts and tell your friends :) check in often we will constantly be adding new parts to the site.  If the moderators or website owner could add this to the links page that would be great thanks :)

Not sure what you are wanting to know or what you want to do so I will give you some general information. You are on the right path but if you are you using the model 35 heads you are making no more than 45-50hp max even ported. Same goes for the stock intake it is the limiting factor. With a good cam, ported model 38 heads custom intake and a solid engine foundation (pistons rods springs etc) you can make 60-80 hp your wallet will limit you check out: and for all you vanguard needs

Mill the head, disconnect governor (aluminum flywheel needed), advance timing, gas port the piston, polish the crank to remove windage, olish the rod, stiffen valve springs, ......... there are a few shade tree tricks
