Need moar boost! - Danny2009 - 01-10-2013
I have a welded td04 and 11mm pump
It has a ground lda and is clean on boost.
I need more boost it's only boosting 20psi I've tried upping the fuel but the revs hang
Played about with the lda no difference
Any ideas what to do need more fuel but hanging revs are stopping me
RE: Need moar boost! - cwspellowe - 01-10-2013
Only 20psi? With a welded gate and 11mm and the revs are hanging?
Doesn't sound right to me. An 11mm turned up that high should make a welded TD04 make an insane amount of boostz
RE: Need moar boost! - Tom - 01-10-2013
Your on an 11mm pump and your max fuel is at the point where the revs hang but your only getting 20psi? Clean on boost rules out boost leak i suppose. Welded gate rules out wastegate creep. Turbos f*cked. What does the compressor wheel look like? Filtered or no?
RE: Need moar boost! - Danny2009 - 01-10-2013
De filtered, turbo seems fine no nasty noises or play
Dont understand, my last td04 I had on a 9mm off a 30psi boost gauge easily
Just thought someone might know what I'm missing

Regardless of whether or not the turbo's f*cked, it's clean on boost apparently. So a f*cked turbo wouldn't make the kind of air to clean up an 11mm that's that wound up.
Does not compute.
What kind of TD04 is it?
RE: Need moar boost! - strictly_perv - 01-10-2013
f*cked turbo would make it coal Tom.
Something's up with that pump then/fuel starvation. A 9mm could easily give coal with a TD04 at 20 pounds.
If there's no blocked fuel filters are you sure it's an 11mm? Because they can give a serious amount of fuel and you shouldn't even be close to limiting it.
RE: Need moar boost! - Danny2009 - 01-10-2013
Td04 13l apparently, don't understand it, coals when reving on idle but even at night absolutely raping it there is hardly any coal if any in the headlight beam of the car behind me
I thought it needs more fuel so tried upping it but started hanging
It was bought off Dave on here he built it himself so I haven't questioned it but even a 9mm will put out more boost and coal than I'm getting ATM
Had a new in tank strainer and fuel filter when I got it on the road for fcs been sat in garage since then just got it back on the road today
RE: Need moar boost! - Tom - 01-10-2013
Im stumped lol
RE: Need moar boost! - Chris_90 - 01-10-2013
Are you getting full throttle? (is the arm moving all the way round) when I had my old d turbo that's what caused me to be down on boost/fuel and I had near enough maxed my pump out to
RE: Need moar boost! - Danny2009 - 01-10-2013
So am I hence the cry for help lol
Yea I've adjusted the throttle stop screw
RE: Need moar boost! - Tom - 01-10-2013
Guess something in the pump then.
RE: Need moar boost! - Chris_90 - 01-10-2013
I no you say you have adjusted the screw but have you actually put your foot Flat to floor on pedal and made sure it moves all the way round?
RE: Need moar boost! - Jenkosowls - 01-10-2013
Have you actually sealed it properly last time I'd seen it it was leaking exhaust gases everywhere
RE: Need moar boost! - Piggy - 02-10-2013
as chris is asking...
my 11mm on the 2.1 is still not quite right as I need to make more adjustments to the arm position...but I wasnt get 100% throttle initially.
get some one to sit inside the car or jam a brick on the pedal inside then see if theres more travel available.
also, I assume the idle screw is out, allowing the arm to sit against the pump housing?
if that is the case, consider moving the arm round one notch, it could be that its one notch or more out.
PS is your lda actually dropping? (and in the right way!?)...remove the spring and go for a drive, see if that helps.
RE: Need moar boost! - Danny2009 - 02-10-2013
Yea I've sealed the plates back up pal
Yea idle screw is all way out guessing I need to knock the arm back?
Lda is in the right way ill check the pin is free in the pump
RE: Need moar boost! - strictly_perv - 02-10-2013
If it's off Dave than I'm sure it's legit. My brothers running a pump off him.
I reckon you just need to do some fiddling with throttle/LDA.
RE: Need moar boost! - Danny2009 - 02-10-2013
I've got no worries about questioning the pump, just thought someone a little more knowledgeable may know what I've missed going to have a play see what I can do
RE: Need moar boost! - Midnightclub - 02-10-2013
Broken boost gauge?
RE: Need moar boost! - Danny2009 - 02-10-2013
Don't think it's the gauge
RE: Need moar boost! - THE_Liam - 02-10-2013
Maybe something with the boost compensator? Is the LDA fitted with the steep curve toward drivers side? Blocked compensator pipe?
RE: Need moar boost! - Danny2009 - 02-10-2013
Thanks for all the help
Checked the throttle with the brick and there was between 1.5-2" of throttle left to go had to mess about with the splines on the arm and the cable max fuel ect goes straight off a 30psi gauge now
Thanks again

RE: Need moar boost! - Ruan - 02-10-2013
Was gona say - typical wrong spline on the throttle issue. But you've got it fixed now anyway :p
