Better intake springs 3hp B&S flathead?

[Budget DIY]

A 10 cibic inch flathead at 15 PSI boost will make FAR too much power to be contained by an automotive alternator or most single V belts.

Secret sauce. It's going to be more then plenty. I was aware of your concerns, but they don't apply.

Are there any auto parts stores nearby that might have car valve springs in stock? Maybe you could take your springs in and find something that will work for you.

Been looking at the parts lists and getting a price for the entire project. Going to cost about 400 euro's, which I'm not willing to pay for a laughs and giggles project. Will post in my intro page what my plans were. This thread can be locked.

Maybe you can contact some of the US manufacturers and explain your situation. They could maybe suggest some cheaper alternatives in the Netherlands. Or they might be able to tell what other engine springs might fit that are more available where you are

I’ve been logged out of the forum and my known password hasn‘t worked but today decided to work for I’m not sure reasons… But anyway if OP is still around I used a smog pump. Another member is using a turbo.

A 3hp making 15psi on a loaded crank as said above would be making quite a bit of power but your never going to spool it.

You’re in the Netherlands? Junkyards for a smog pump would be cheapest and easiest to setup as draw through friction drive.
