LR5V Posted November 9, 2018 Report Share Posted November 9, 2018 I cant understand why the intake comes all the way from the back of the engine to the turbo?? From the MAF, diverter and boost sensor it looks like its running 1.8t management 276 bhp - From this thread Quote Link to comment Share on other sites More sharing options...
mk2 Posted November 9, 2018 Report Share Posted November 9, 2018 Looks like the cold air inlet comes from behind the engine. Very odd. Quote Link to comment Share on other sites More sharing options...
Sausage Posted November 9, 2018 Report Share Posted November 9, 2018 (edited) I'd have run that down to the TDI filter location if there is room there on a GTI, but looks like he has the filter right next to the inlet manifold (if that is the start of a cone filter i see there). Odd, but maybe he already had the parts and they dictated it go that end. The inlet manifold should be the coolest part of the engine, but that would be quickly offset by the engine temp under the bonnet, better off out front away from any heat. Water cooled turbo too...

mk2 Posted November 9, 2018 Report Share Posted November 9, 2018 I've just noticed that they used an inlet manifold for a NA engine. That would mess with with air flow and increase the plenum volume=not good. Big delay. Quote Link to comment Share on other sites More sharing options...
Rich Posted November 9, 2018 Report Share Posted November 9, 2018 I think getting 276 out of an avy is admirable regardless of how they're doing it Quote Link to comment Share on other sites More sharing options...
mk2 Posted November 10, 2018 Report Share Posted November 10, 2018 Just noticed the scum line in the coolant header tank. I wonder how many HGs he's been through! Quote Link to comment Share on other sites More sharing options...
Sausage Posted November 10, 2018 Report Share Posted November 10, 2018 (edited) I'd be pretty chuffed if I'd done this, minimal fab, tidy install. i hope the single jubilee clip around an inch of rubber is just covering a small hole or something though....(a mount probably) What's the valve thing joining boost side to intake side? Emissions stuff? Cant see why it joins boost side as well. (stealth dump valve?) Edited November 10, 2018 by Sausage Quote Link to comment Share on other sites More sharing options...
LR5V Posted November 10, 2018 Author Report Share Posted November 10, 2018 They all look like 1.8t stuff, wouldn't surprise me if it had ECU as well - I believe its a MAP sensor attached to elbow onto inlet and a standard bi-pass valve above the rocker releasing boost back into inlet - it is metered air, dumping to atmosphere creates a lot of problems on 1.8t's I know someone who runs a daily Mk4 with big power on an OEM ecu. He maps it himself and despite being standard management it is very versatile. Quote Link to comment Share on other sites More sharing options...
mk2 Posted November 10, 2018 Report Share Posted November 10, 2018 Why didn't he use the oem diesel air filter box that slots in, just in front of the RHS wheel. Nice short duct into the turbine. So much neater and more flowy. yeah bosch ecus are very good. You can indeed keep everything completly stock, chuck in a supercharger and just change the injectors. Then just a remap. Sorted. 2.5x stock power. Quote Link to comment Share on other sites More sharing options...
LR5V Posted November 10, 2018 Author Report Share Posted November 10, 2018 Could it be the Gti Xenons taking up the space stopping that option? Quote Link to comment Share on other sites More sharing options...
LR5V Posted November 10, 2018 Author Report Share Posted November 10, 2018 Weirdly this just popped up on ebay https://www.ebay.de/itm/ROTHE-MOTORSPORT-GMBH-TURBO-KRUMMER-GUSS-KRUMMER-1-6-L-16-V-LUPO-GTI-/292366541837 Cant search from UK ebay - only listing Germany for postage, needs the matting surfaces machined and stud holes need drilling Its designed for a K03 - why bother just fit better K03s Quote Link to comment Share on other sites More sharing options...
mk2 Posted November 10, 2018 Report Share Posted November 10, 2018 Yeah, i get my bits here....

Rich Posted November 10, 2018 Report Share Posted November 10, 2018 And I remember someone on club Polo (possibly guy) experimenting with g60 rods (machining the sides) on an avy. 136/138 centre to centre. Quote Link to comment Share on other sites More sharing options...
mk2 Posted November 11, 2018 Report Share Posted November 11, 2018 Then you need to do some balancing. I can never get my head around how crankshafts are balanced. As soon as you change the rods for say lighter titanium types, the big ends will obviously be lighter. But the crank webs don't need to be touched! Huh? I've always temporarily assembled everything as a piston/gudgeon pin/rod and bearing assembly (including the big end bolts). Then with some digital kitchen scales, resting the piston on the table and keeping the rod horizontal, weigh the big end. Then grind a little off the sides until each big end is the same as the lightest one. Then the next step would be to remove some material from the crank... but i never have. I don't get it.

There didnt seem to be a cheap option to do this when i briefly looked into it. Edited November 12, 2018 by Sausage Quote Link to comment Share on other sites More sharing options...
LR5V Posted November 12, 2018 Author Report Share Posted November 12, 2018 He lists off the software in this thread on UKMKIV's page 1 of 40 (!) post 13 - his custom dash build is something else and currently the Golf is 400bhp on K04 with forged internals Quote Link to comment Share on other sites More sharing options...
Sausage Posted November 12, 2018 Report Share Posted November 12, 2018 Thanks, he's a top bloke, wish I still had his age and enthusiasm. looks like boot mode on the bench then, I was hoping for OBD options. Quote Link to comment Share on other sites More sharing options...
LR5V Posted November 12, 2018 Author Report Share Posted November 12, 2018 Yes he is - he offers to re-map / code out stuff in your ECU by post if that's any help Quote Link to comment Share on other sites More sharing options...
