I hate to bust your bubble. But any noted power / torque improvement is no thanks to the VS exhaust. It'll be all due to the dual carbs and dissy. The VS is just a big shiny stock exhuast giving next to no improvement in performance. Get a basic 4into1 header to get half decent scavenging effect and improvement in exhuast flow. But yes, those dual carbs and the SVDA it a good improvement for a healthy 1600 in a bus :)
Road tests completed before and after carbs and exhaust. Carbs were a great improvement during road tests on the stock exhaust, the dissy made it smoother. The vintage speed did provide additional gains in smoothness and power delivery when fitted. Not as much as a 4-1 or merged header for sure, but it's a 1600sp not a highly modified larger capacity motor. For daily driving of such a setup its perfect. I run a VS on my 2110cc and the difference between a 4-1 was negligible. I drive it long distance in a heavy bus so happy with the performance/ design as not looking for all out power and the drawbacks it can bring.
@@wayoutwestiemike There's obvious something wrong if your not getting any significant gains between a VS (big shiny stock exhaust) and a decent 4 into 1 with a decent muffler. Have proven this on a dyno? Yes, it's a stock 1600 engine in a bus. But why paid all that money for a VS exhaust in the first place if there's next to no gains. I agreed the dual carbs while small are a decent gain considering its a, stock engine and the dissy has bonuses all round such as improved torque, smooth accelorator from any rpm and better cooling due on piont timing that's best suited to a heavy bus which leads to better fuel consumption and longer engine life. Yes the VS is more open so therefore allowing the improved fuel burn thanks to the carbs & ignition to excape more easily than the stock exhuast. But it's only assistant is somewhat like a stock exhuast having a hole in the muffler and sounding better. There's no assisted scavenging effect going on with a VS. So my piont is you could achieve similar performance improvement as the VS simply by using a twin tip stock exhaust and replacing the restrictive twin Pee shooters with straight pipes in place of the baffled Pee shooter - try it! It's a lot cheaper option and when mixed with the dual 34ICT's and SVDA dissy as you have, it a best bang for $$ spent for torque / Hp gain. If wanting to go beyond this then step straight up to a decent 4into1 and dual 40IDF's and the stock 1600 will wake up to another level. However, as you mentioned the stock bottom end might not be up to it. Please keep your vids coming because I do believe your vids is all good info for the VW community.
Nice. I see it’s running a stock fuel pump, does it have anything to regulate the fuel psi or is that not required ? I’m interested in running 34ict’s on my 1600dp and just wondering what I need.
Yes it has a malpassi petrol king pressure regulator. Stock pumps can put out up to 5psi and Weber icts need no more than 2.1psi of consistent pressure. I fit malpassi pressure regulators on all of my installs otherwise the needle valves get overpressure and leak.

nice work twin weber 34 ict carbs work great 👍
Love that sound, roll on summer.

Sounds excellent, I’m guessing the split is still running reduction boxes ? Nice job 👍
