bruteforce Posted January 6, 2016 Author Share Posted January 6, 2016 (edited) A little history on the build of my TurboGS. This starts way back in 2003 when I got a GS750 as a gift from a buddy of mine. Ofcourse it made no sense to refit the GS750 lump, so a GSX1100S engine was puchased and fitted with a Wiseco 1168cc big-bore kit. It made 120bhp at the wheel. Then I got overtaken by a standard modern 600 so I thought I'd be a good idea to fit a turbo under the seat in Yamaha 650 TurboSeca style. Now I didn't get overtaken anymore. It started life at 160bhp in 2005 with a VNT turbo... ...and eventually made 210bhp and 220Nm at the wheel in 2007 on a KKK k-04. Then someone offered me a slabby GSXR1100 for silly money so I changed direction completely and turboed that the "proper" way with a front mounted turbo, alas on standard pistons and bore. The GSXR turned out to be cheap for a reason: the engine was very very bad and this meant that it kept letting me down time and again for years to follow. But in the meantime I preferred the GS looks so I built a new TurboGS for it, based on a GS550 frame after I saw one fitted with an oilboiler 1100 at Santa Pod. It is now 2009 and it became 1195cc on very low CR busa pistons. So I ran it for a couple of years still struggling to get decent reliable power from it, went to meetings on it but not much else. Then in 2014 I badly damaged the engine on a high-speed run so it was time to completely rebuild the motor. It still looks the same, but now has a revised head with new valvesprings, new busa pistons and bores, corrected camtiming, block skimmed for 1mm squish and 1:8.7 CR, restrictor in the turbo oilfeed and a new turbo scavenge pump running off the crank end. This was done because the engine apparently was starved of oil at some point and I blame the old restricted membrane scavenging system. We're back for the 2016 season!

bruteforce Posted January 7, 2016 Author Share Posted January 7, 2016 ...I told you to build an 1100 straight away but noooo you did a 750 first. Lovely and very fast bike though. I noticed that I don't quite fill that suit up like that nowadays... Quote Link to comment
Maggotbreath Posted January 9, 2016 Share Posted January 9, 2016 (edited) Awesome to see you're back! Didn't we do a deal for a yami reg years ago? I always thought your gs550 was one of the most perfect Turbo bikes ever! I really should copy it some day. Edited January 9, 2016 by Maggotbreath 1 Quote Link to comment

snoorder Posted January 25, 2016 Share Posted January 25, 2016 (edited) Welcome back / Welkom terug Marco! All those bikes were impressive! Any projects going on at the moment? Edited January 25, 2016 by snoorder Quote Link to comment
bruteforce Posted January 29, 2016 Author Share Posted January 29, 2016 At the moment I'm trying to get a crank-driven scavenging pump to work well. It seems to be a bit small to be able to get the hot frothy oil back up. But the engine rebuild has been fully completed and all else it needs are new floatneedles and seats. No other projects I'm afraid, still considering EFi but not sure it will bring me more than a good set of carbs will. 1 Quote Link to comment
