VW 1.6L Pump Upgrades / How Bosch VE works 

Can you link the part you bought 😊

Oliver, your videos are a tremendous contribution to the VW IDI community. I know you're not getting a massive number of views right off the bat, but these are going to be reference materials for wrench twisters like us for years and years to come. Thanks, dude!

Thanks for the video. I have an '85 Mitsubishi Pajero with the 4D56T that runs a bosch type injector pump. A local shop made a right mess of it, damaging the housing and then setting the pump up in such a way that the vehicle can barely do 80 km/h. I fiddled with a few things like fuel delivery valve and boost compensator diaphragm mod, but I discovered the pump is cocked over so far advanced that it is fouling against the timing belt cover. I can't mess with the fuel delivery any more as the idle gets too high and that opens up a whole new can of worms. While my efforts mean I can at least see 100km/h she gets up there on the EGTs and with a few other things I've noticed, I think I have some more investigating to do. I then did some more research 2 days ago, because I thought the fuel cut of solenoid was faulty as it wasn't shutting off, but this turned out to be a problem with the alternator, which is fixed now. In my research I found that no one in South Africa has any info on my specific pump number, which makes me think the shop that 'fixed' it also doesn't have the info so they simply cobbled it together with some parts lying around. I had sent the pump out of town before them but the shop didn't have any info on it and sent it back in a parts bag. This is what makes me think the shop that assembled it for me just guessed what went in this specific pump, set it up as best as they could on their test bench and that was that. At least your videos I have watched has given me some confidence to at least see what pump head is in my unit.

Good job can't wait to see the results..

Cool! I DD an 81 rabbit with 1.6L TD with all the correct stock mk1 TD parts under the hood. Has a few tricks done but nothing crazy, its a daily. Like the York logo, have a lot of York related items even Steuben Mtrs, pre York.

this is the moment i was wating for!

Absolutely awesome channel! My high school son and his friends want to build an off road vehicle with a 750 Kawasaki…..and I’m pushing them to go with a VW 1.9 or 1.6. My gut tells me a 1.6 with a mechanical pump vs a 1.9……thoughts?

hi! Could you tell me if your VW head pump is right or left? I want to buy one through Ali Express but I don't know what direction of rotation it has! thank you, very good videos! Greetings from Uruguay

See how it runs on stock timing and maybe a touch more advance - after that you may want to try the advance plunger extension to get some more dynamic advance as rpms rise.

Any updates on how the pumped performed? I tried something of the same on a 1.6td pump using an 11mm from a 1.9tdi ahu pump. After about 2 to 3 weeks, the rpm started to gradually go up and up, and i had to back out the throttle screw and the fuel screw to lower rpms until i couldnt anymore. Just checking how did yours go??

FYI you should do a driving video after the mods you did. Then post it. Then download the footage from this video do a re-edit of this and the other. I do that and they go pretty big. Just put the footage together and talk about the problems between you might have had.

This might be a noob question but isnt changing to a bigger plunger just the same as increasing fuel supply on the max power fuel screw? For exemple, a 10mm with increased fuel screw would deliver the same fuel as 11mm with stock fuel screw no? Thanks

Hell yea keep it up 😀

wow man thats ace!!

Hey Oliver! I saw you got a VNT. I've created a Arduino based controller for my 1.6D (Golf Mk1 just like yours). Gives super fast spools. Could send you one for free & help you set it up. What do you think ;))?

Hey looks like my messages are not coming through, is there some other way to contact you? I got a git repository with documentation on the hardware and software for the Arduino

"Special word of caution" lol

People talk all bad about Proth.....(aka Hans auto parts) but they are really one of the only people selling parts for these older cars. For late models. NOOOOOOO.....but for early cars they are the ticket.

Hans auto parts is very well known garbage parts peddler I would stay away from them. Take a look around about em.
