Welcome to Bang 4 Buck Racing! The goal of this channel is to help you the car/motorsport's enthusiasts on how to mod your cars without breaking the bank. Achieving the results you want with out feeling like you have to spend a butt load to get your car on track or looking good!
Whole point of the standing test is that you can stand in the drawer without it tipping over. Someone holding the box up defeats the purpose of the test
the only issue i have with this is people who don’t know what they’re doing trying to go too fast. notice how he picks up the drill every second or so and replaces it. if you don’t do that you’ll grind a canyon into your valve seat. and at those speeds its easy to do.
" Concrete pad" why do they always call it a pad instead of a patio or just cement "The cement in my garage? No the concrete pad Pad makes it sound like its soft like a landing pad
50 years ago I used a suction cup on a stick by hand. That was tedious. So, I chucked it in and electric drill. That was much faster. We didn't have a vacuum pump so we just did until we got a nice even shiny area on hte seat and called it good enough.
I recently saw a man that presented himself as knowledgeable on the subject say that the cold side volume doesn't play a significant role in the time to charge. There are drag cars with front mounts that pipe to the trunk to an air water intercooler and then back to the engine.
Isn't this the same as putting the valve directly in the drill from the other side? Same outcome same concept different methods. Basically do u want to maybe mess up the valve stem by putting it in the drill or do I trust friction and buy this tool
Interesting video, thanks. I am not a mechanic so please pardon the question but, instead of pulling a vacuum, is it not possible to blow compressed air in? And if so, how much psi would be needed, thanks.
You can used compress air but sealing it off becomes more challenging. You would either need to bolt the tester to the intake manifold holes and test or another way is to seal off the chamber on the headgasket side and test through the spark plug. And for psi the trick would to be is pressurize the port say 60 psi then measure how long it takes to leak out and try to equal that across all ports. With the vacuum gauge it’s easier to see okay this one pulled 24 inches of mercury and then this one pulled say 15 so you can do more lapping to get it closer to that 24.
Hrmm, I'm curious as to how you came to the conclusion a smaller internal WG spools a turbo faster than an external gate? Dig a little bit deeper about the builds, what other changes are there from the IWG to EWG setups. The size of the Wastegate aperture doesn't have an effect on spool if everything is working properly.
I’ve had the discussion many of times and every single the person arguing for EWG can’t show me a dyno sheet making full boost and peak torque before 4000 except maybe 2 people. Regardless of IWG or EWG it is simply just a pressure relief port. EWG do their jobs good i just say they do it to good. When a 38mm port opens for the same amount of time a 32mm port opens it will relive more pressure every time. And that’s less exhaust gasses spinning the turbo. Especially on the standard 3 port boost controller setup most do. I don’t think an EWG can’t spool fast as well, but I have multiple dyno sheets in my possession all spooling below 4000 rpm still making great power on IWG. a lot of tuners are uneducated and unfamiliar with how to properly tune a dual port WG internal or external and with a proper 4 port boost controller. It will yield much better results they are just slot more difficult to dial in. Small changes can make huge jumps in boost made.
I use a couple inches of 1/4” vacuum hose, chuck one end in a drill, stretch the other end over the valve stem, pull slightly and send it. Free and easy
I find it funny that people in other countries can lap valves with whatever they have on hand, hand tools, power tools, bow drills, etc and everyone always dogs them in the comments but if someone in a well lit clean shop that speaks english does the same exact thing to the same exact motor they're the expert and their motor is instantly 100x more trustworthy than the guy in sandals working on a dirt floor.
