johan238 31 Posted February 16, 2016 Author Report Share Posted February 16, 2016 Alright guys Its been ages since i last updated this thread. Well what can I say, things didn't go too well after the last engine build I managed to complete 1200 run-in miles and then took it to stealth for some mapping where it decided to give up on me, on the rollers!!! After a little bit of an investigation it was found that I had spun another big end bearing, due to not cleaning out the pressure relief valve on the oil pump. I wasn't happy to say the least!!! Well that was that for nearly a year. Work commitments and other things left me with very little time to work on the car. However i managed to find some time in January to rebuild and fit the engine. I also managed to to take a video of the engine being fitted. I have posted a link to the video below Mk2 Golf supercharged VR6 engine install I have managed to get the car up and running again, although i have an idle issue which i'm currently chasing. I'm afraid i haven't got much else to update at the moment as i have gone away on work again. I am hoping to be back home in just over a week, then i can complete the run in miles and hopefully get some good videos of her finally on WOT bennyk, D11PS, VR6Pete and 1 other 4 Link to post Share on other sites

matty.vrt 120 Posted February 16, 2016 Report Share Posted February 16, 2016 Looks like you have had a difficult time with it. I think the fact you have stuck with it is a real testament to your commitment. Hope things start to go better for you. VR6Pete 1 Link to post Share on other sites
VR6Pete 1,455 Posted February 16, 2016 Report Share Posted February 16, 2016 Mate well done for sticking at it. Looks great! I know many people would have simply given up! Link to post Share on other sites
johan238 31 Posted March 21, 2016 Author Report Share Posted March 21, 2016 Hi Guys Last time I left you I had got the engine in and running but it wasn't running that well. I finally finished the job I was away on and i have managed to get some hours in on the golf! After scratching my head for a while I decided that the idle issue must have been caused by either a boost/vacuum leak or a dodgy ISV. I decided to start by checking for boost leaks on the inlet track as I wanted to be sure that there were no leaks anyway. I knew this was going to be a bit of a pain as the engine was in and all timed up so at least one valve would be open which would mean it would try and pressurise the whole engine. i managed to get around this by pulling the crank case breather pipe off the oil catch can and plugging it. I then turned the aluminium pipe by the supercharger and fitted a metal plug that had an air line fitting welded to it. Then using one of those crappy electric compressors that you blow your tyres up with i was able to pressurise the inlet track. Using water and fairy liquid in a spray bottle I was able to spray any mating faces/pipes and checks for leaks. It was a good thing I did too as I found a leak on the ISV pipework, a leak on a vaccum line that fed the fuel pressure regulator and a massive leak on the dump valve. The valve head of the dump valve wasn't seating properly on its seat so it was just passing air all the time. I was able to lap the valve head back in to the seat which re-introduced the seal. After fixing all the leaks I then refitted the aluminium elbow and started the car. She ran better but still had the same idle issue. Here are a couple of pictures of the setup I used to check for boost leaks. I was very happy with how well it worked as now I can be sure that I will have no boost leaks that could cause a loss in power, and we don't want that!!! After fixing the leaks and not getting rid of the idle issue I was pretty sure that the ISV would be the cause of my problems. I removed the ISV and put 12V to it to check that the flap opened, It didn't! Because I didn't have a spare and couldn't get hold of one quickly I decided to see whether I could fix it myself. I had read on the net that you could put carb cleaner or electrical contact cleaner in them and some times it got them working again. i tried this but it didn't work. I decided to pull it apart so i filed the pressed tabs off the top of the ISV where the power supply connects. I removed the cap which gave me access to the internal working of the ISV. I was then able to tap the centre shaft out of the ISV and this is where the problem was found. When I removed the shaft there was a load of hard brown crap on it. Using some fine emery tape i cleaned up the shaft and fitted the ISV back together. I then put some power to it and boom, The flap opened!!! I refitted the ISV in to the car, started her up and she ran sweet. I am now completing the run in miles on the engine. Hopefully in the next few days I will be able to put up some videos of her being fully opened up. Speak soon c00k and D11PS 2 Link to post Share on other sites

I managed 293BHP @ 6770 RPM and 230 ft/lb of torque @ 6030 RPM. Its only managed to gain 4BHP with the charge cooler setup. I have a 12 psi pulley that I am thinking of using to get the figures to over the 300BHP that I wanted but we shall see. Im hoping I might be able to eek out a few more horse power just with a few tweaks Bealieboy 1 Link to post Share on other sites
matty.vrt 120 Posted April 4, 2016 Report Share Posted April 4, 2016 I know the feeling, mine made 270bhp with stage 2 pulley and 268 cams but drove great. 12psi pulley should see 320bhp from what I've seen. Bealieboy 1 Link to post Share on other sites
dom.joy 87 Posted April 5, 2016 Report Share Posted April 5, 2016 Shame about the engine troubles but good job in keeping going. What diameter pulley are you using?And what psi? Link to post Share on other sites

What is this for ? Honestly I have been asking myself this same question for a long time. It goes to a braided line that runs around the supercharger and in to the pressure side of the charger housinf. I will see if i can find a picture that better shows you VR6Pete and Bealieboy 2 Link to post Share on other sites

What diameter pulley are you using?And what psi? I cant remember the pulley diameter off hand, but its the 8psi pulley. I am however not making 8 psi, from what i can see from the digital boost gauge I am making just over 6.5psi. I believe this is because I have increased the volume in the inlet and the supercharger cant push that amount of volume at the same pressure. I am thinking of machining the pulley down slightly to increase the RPM on the supercharger and therefore increase boost pressure. I have a 12psi pulley kicking about but I am apprehensive to use this as I would probably have to use a decompression plate. Link to post Share on other sites

If you do get the chance to stick a ruler or caliper accross it let me know. I'm looking to get mapped to 8psi soon Link to post Share on other sites

I have ran 11psi on my turbo'd setup without a decomp plate, so with the pressure losses you are experiencing I think you would be ok. Link to post Share on other sites
