Thread: td5 boost and egr setup

Ill talk about the second question.

To see if its reomoved you will need to take the acoustic cover off (three 13mm bolts) and you will either see this (blue circle thing)





or a short piece of pipe in its place.

Read this link to see what it does etc.

Td5 Alive! Td5 EGR Bypass Kit - Performance Diesel Tuning for most modern Cars and Vans.

Look in the tutorial section of this forum for a thread BlkNight did on how to remove it. EDIT Here it is - http://www.aulro.com/afvb/projects-t...r-removal.html

1.17bar is colse to 17psi. thats correct for a TD5.

do a search for egr blank or egr removal.
im not gonna start that old chesnut again

cheers phil

ps. mines removed....for the better

without going outside, i already know that i have the egr thingy there then from last time the cover was off. i'll have a read of that thread. seems i may be removing mine too though...

That's interesting, as mine was 19psi at the turbo before fitting the larger I/C and now its 17psi (according to a cheap gauge). So there's not much flow restriction now between the turbo and the MAP sensor in the inlet manifold. It still has the EGR and ILT valves (although neither operate) so they're not causing detectable restriction at full boost, but perhaps a different story during turbo spool-up.

Got my Nanocom now.

My boost pressure maxes out at 1.06bar, a bit over 14psi, seems a but low?

I have Tombie's intercooler and a BD enhanced chip.

Wastegates need adjusting???
Couldnt find anything on RAVE but I messed with mine last nite.
Undid the locknut and adjusted it about 1 nut width to get it to fully close.Untested as yet as the D2 is in the shed under surgery.I read a post here a while ago stating that you need to ensure the wasgate was adjusted to close properly.
I was getting no boost at all(acording to nanocom) until after 2000rpm under light throttle,bear in mind 2 exhaust stud nuts and 1 complete stud were found to be missing and soot says it was leaking.

hopefully a graph will appear below thats a screen shot of nanocom output. showing revs boost and wastegate modulator. to work out actual boost you have to minus ambient pressure from the inlet air pressure i think!



Thanks

I have been running my wastegate adjusted fully closed with the engine off for over a year now.

EGR removal definitely lets the turbo spool up better as the EGR comes in after idle. See some threads on my setup as I have just about zero turbo lag when flooring the pedal OFF IDLE and no turbo lag at all out on the road when I hit it.

Removing the EGR alone will not set your TD5 performance on fire but mixed with other mods it helps a lot.

Are the Nanocoms worth it or should I spend the bit extra and get the "Black Box" unit that does everything on the D2?????
