jonnyoutram 0 Posted January 11, 2008 hi, i have had never ending problems with my bbm screw charger, had about 3 replacements after 2000 miles each time, i have now decided to go back to a standard charger as i feel it will be more reliable. does anyone know? what parts will be needed to re fit the g60 if all i have is -the necessary parts to fit a screw charger -1 random boost pipe with a little breather on it?? thanks people :lol: :lol: ps. looking for a full black carpet and passanger doorhandle... going to check partas for sale now..

junkie 0 Posted January 11, 2008 should be a straight swap back to a g lader and the pipe with the filter on i suspect was the boost return to the g lader. Quote Share this post Link to post Share on other sites

G60SC_Stoney 0 Posted January 11, 2008 well i hope mine will be ok, as its going to be getting a hard time when its fitted to my 16vG60....if it decides to eat itself then get sucked into my brand new expensive engine i wont be best pleased, may invest in a rotrex.... :lol: Quote Share this post Link to post Share on other sites

jonnyoutram 0 Posted January 12, 2008 i suggest no one ever buy's a bahn bremmer, they have ruined my life i have had 4 i think, lost count, and they kept ceasing up! darren could not work out y it was happening so now im just going back to the g ladder cos i know it used to work... i was never able to get enough boost out of the lysholm anyway, it didnt feel as impressive!!! unfortunately, bbm are not helping any more so i am fighting it but it looks like im going to loose 2k!!!! i love the sound of that stage 4 but my screw chager is screwed!!!!!!!!!!!!

Shaggy 0 Posted January 12, 2008 The main reason they keep seizing is because the bearings "opcon" are now using on the Lysholms are shite.. and are not up to the job, even Bahn Brenner confirmed this when i queried them a few months back, they said it had been sorted?? Ever since Opcon was taken over by someone else the reliability of the chargers have gone down hill.... I ve heard of loads of the newer units failing because of this.. and until its rectified i wouldnt touch one with a barge pole unfortunatley. And as for the rotrex chargers.... well i ve been told they arent up top much on the smaller capacity engines.. Good on the VRs tho. Best of keeping the g-lader at the moment or going turbo. 8) Quote Share this post Link to post Share on other sites
junkie 0 Posted January 12, 2008 Agree about both points of the rotrex and turbo :D Quote Share this post Link to post Share on other sites
CrazyDave 0 Posted January 13, 2008 I saw a Rotrex conversion on a 20v engine in a MK1 at E38 this year, producing 0.5bar of boost at idle. It was early days for the owner, but seemed very good. As with all FI, getting the charger sizing correct is the name of the game, so I can't see why a Rotrex wouldn't be very good on a 1.8 engine. Just needs to be the right one. The Rotrex gearbox is very efficient so you should get lower losses than a G-lader or a screw compressor. Quote Share this post Link to post Share on other sites
Shaggy 0 Posted January 13, 2008 Yeh, i guess with more research they can work very well on the smaller capacity engines, i am just going by what other people have said, (no power at the low rev range) its a fair whack to spend to find out its not as good as it has been made out to be.

CrazyDave 0 Posted January 13, 2008 With such a low mileage between chargers, sounds like a case of 'unfit for purpose' to me. As others have said, they used to be very good. Quote Share this post Link to post Share on other sites
samg60 0 Posted January 13, 2008 I can only comment that I had the same problem, the kit was not a bahn brenner unit but exactly the same spec, it was fine at low psi but as soon as I ran an 18psi unit things went wrong, I think they run far to hot and the expansion etc just causes them to sieze as the tolerances are far to low, i would suggest you go down the turbo route for good hp, worst £1500 i ever spent on a lysholm, although it was fast when it ran. so happy i own a turbo now.

junkie 0 Posted January 13, 2008 I ran 1 when they were good albeit for 4k then sold it and went turbo and it was the best thing i have done, but the warranty does say if you use a smaller pulley than supplied then it voids the warranty so you run a smaller pulley at your own peril which i did 1k into the charger. Ran the 50mm pulley and it made 1.1bar with all the engine mods working so well. Quote Share this post Link to post Share on other sites
KADVR6 0 Posted January 13, 2008 JMR is now a stockist of Rotrex and is about to fit one to his 16VG60 who??? r-tech sell the brackets etc etc to attach them to a g60 http://r-techs.dk/en/brackets-60/vw-62/ ... i-415.html and here is the charger i would say you would need http://r-techs.dk/en/supercharger-27/c1 ... 60-56.html use a 75mm pulley, and you should see about 12psi of boost, use a 65mm pulley and that should see ya getting approx 18psi.

mondy 0 Posted January 13, 2008 This all makes for depressing reading - I've got a BBM charger ready to go on my car once I've finished rebuilding the engine! I did have it on the engine for about 400 miles before the engine rebuild and noticed then that it seemed to get quite hot :( Getting back to your question there's not much you'll need to swap it straight back to the G60 - you'll need the rear mounting bracket and gasket and I think the oil return pipe is slightly different, I don't think there's anything else you'll need though. The outlet pipe that goes to the intercooler might be a bit different as well depending on your setup. Quote Share this post Link to post Share on other sites
