The current project is building a custom cross kart, mini buggy, that will feature a 1000cc V-twin Superbike engine with 135hp, a tandem two seat layout, and a lot of custom parts fabricated right here in Provin's Garage.
I design, build, customize, improve, renovate, fabricate, and innovate various things on a regular basis but mostly focus on vehicles and going fast. I like to think of myself as a creative problem maker
I'm running a dual catch can system with one working as a vent to atmosphere and the other is attached to the intake manifold with a check valve so it doesn't pressurize under boost.
mines fine after 14k miles. The problem is people over torque the bolts and don't use the correct pattern and warp the tank seal lip. Warped lip = poor seal. The bolts only need 3 ft lbs.
if its building to 25mm of vacuum that's way over what the brake booster needs. most boosters only need 15-18mm. so even thought it is cycling on when you hit the pedal it is building more than needed which isn't a bad thing.
If you still have this bike, you should bring it back on the channel! This is your second most watched video to date. Us Virago people are always looking for new content on those old gems!
if you weren't using a vacuum booster for the brakes you really wouldn't need a vacuum pump. that is unless you had other vacuum accessories like the a\c blend doors or 4 wheel drive actuators, in that case yes you could run this set up to power anything needing vacuum.
Very cool man. I have an old FMF exhaust I want to use on my go cart but I don’t know how to weld at all. This has been useful as there’s very few videos on RU-vid about go cart exhausts
If you still have anxiety about the reliability of that set up, if it did not come with a vacuum reservoir, adding one can give you several extra pushes of the brakes - good especially if the car stalls for some reason or you have a battery that is getting near the end of its useful life.
@raycox1971 I don't blame you. I ran it for a while and went back to using the engine vacuum. I'll hang onto the pump though in case I do a future build with a motorcycle engine and want power brakes.
as time goes by, I don't want any more noise, vibration.. guess it's getting old who knows... but with all the tech we have, you'd think there would be a silent one.... I guess oem has is down, but the aftermarket is lagging.@@provinsgarage
