smo Posted October 24, 2007 Share Posted October 24, 2007 I'm seriously considering trying to add a supercharger to my TD5 engine on the d-Lander, in addition to the turbo. Has anyone ever tried this (other than VW with their Turbo/supercharged engines) and are there special considerations i might have overlooked??

dollythelw Posted October 24, 2007 Share Posted October 24, 2007 why not run a paxton and just bin the turbo? Quote Link to comment Share on other sites More sharing options...
smo Posted October 24, 2007 Author Share Posted October 24, 2007 why not run a paxton and just bin the turbo? Because they are expensive and dont seem to offer any great advantage over a roots, let alone a roots+turbo setup, i could be wrong tho.

RRX Posted October 24, 2007 Share Posted October 24, 2007 you would be better off ditching the turbo and fitting the blower instead of twincharging. Or fit a VNT turbo as this will drop turbo lag to a minimum. Quote Link to comment Share on other sites More sharing options...
dollythelw Posted October 24, 2007 Share Posted October 24, 2007 the delivery is less harsh than a roots, also easier to package, install, intercool and pipe up on a Td5 I would have guessed. Propane it Quote Link to comment Share on other sites More sharing options...
smo Posted October 24, 2007 Author Share Posted October 24, 2007 I have thought about propane, or LPG but not sure how to go about getting the control right on a TD5 Quote Link to comment Share on other sites More sharing options...
66gaza Posted October 24, 2007 Share Posted October 24, 2007 What about compound turbos? the smaller turbo boosts as normal and a larger turbo kicks in when boost rises giving you the best of both worlds. Its like VGT turbo but more so. They are DIY fabbed for cummins engines so can't see why you can't do a TD5. keeping boost down would be the biggest problem Gaza Quote Link to comment Share on other sites More sharing options...

66gaza Posted October 24, 2007 Share Posted October 24, 2007 I have very little knowledge of how these work so designing a system using one would be er...tricky! here is a link to a pic http://rides.webshots.com/photo/1136225115042569021oFQERr This should give you an idea of how they go together. I would imagine it to be a lot easier and cheaper than adding a supercharger. you would be keeping the original turbo and feeding it into a bigger one. in the cummins world people have had sucess with a wide range of turbos indicating the you have a range of larger turbo choice and size is approximate rather than exact. The size is roughly twice the CFM of the smaller one. Don't write it off so quickly, compound turbos will be the next thing for performance diesels. I think the diesel Audi that won le mans was compounded. Gaza Quote Link to comment Share on other sites More sharing options...
Steve Hiatt Posted October 25, 2007 Share Posted October 25, 2007 Personally I'd sell the TD5 and fit an LS1 Jeremy Fearn is the chap you need to speak to, he knows the TD5 inside out and has run twin turbo systems in his racer. I hear he now has a rolling road to perfect setups. Quote Link to comment Share on other sites More sharing options...

We were up there a couple of weeks ago and it was still the BMW lump. I thought someone had already Supercharged a TD5 ? Was there not a website somewhere explaining it all?

honitonhobbit Posted October 25, 2007 Share Posted October 25, 2007 When it comes down to it the TD5 is a good lump but it is only icckle. If you have power issues in something so light then I would look at what the cause is not simply look for more horses. Quote Link to comment Share on other sites More sharing options...

RB26DETT's count as equivalent replacement don't they? taken from the HH's useful link: All RB engines have belt driven cams and a cast iron block so that'll be nice and light then just like the original Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 25, 2007 Share Posted October 25, 2007 so that'll be nice and light then just like the original I think I could live with that though: It is not uncommon for 600 hp to be achieved on the standard bottom end. Actually, that'd make a good replacement for a TDi - probably similar MPG, much more horsepowers, can't weigh much more if any, and twin turbos as standard. Hurrah, back (almost) on topic! Sorry!

Still BMW as far as I am aware, I should have worded my reply better. I meant he had experience of twin turbos, TD5's and off roading rather than all three at the same time.
