TDi boost levels. PD130 max?

[air121005]

After doing a few searches, i am suprised to learn that TDi's run such hich boost, standard ~20-25 Psi / remapped ~ 30 psi

my query is, what is the max boost a PD130 turbo and associated parts will run at regularly / reliably?

i am also intrested in this, i always thought it wasnt the boost level that killed the turbo but the EGT's caused by high boost levels, so you could run high boost if you can get lower EGT's by getting a free-flowing exhaust.

already got one

not an expert on engines by any means so couldn't comment on what kills turbo's.
would have thought boost pressure would have been the major killer though

dunno then lol, id say it was a contributing factor

well mine was running 200bhp and 322lb ft torque with 1.6bar boost
i would not want to put 2 bar plus through a stanmdardd turbo mate
t-spark did it and after a few miles it started to make its way out i believe

wouldnt have given you 6 bhp, look at the mods ive done on my car, and ive gained f*** all

 

[strugers1]

well if the fmic gave me 17bhp i think it would have and it did blatent mate anyway 222now lol

I did not get any more after my decat either Brad. Tell a lie I did get something, a bloody great roar from the exhaust at full throttle, thought the exhaust had fell off!

No gain from decat on a diesel if you think there is you live in dreamworld

stock pd130 boost is around 17 to 18 psi, and remapped no higher than about 24 psi - based on the stock turbo anyway. I don't even run 30 psi and I'm running a hybrid.

 

[strugers1]

i beg to differ my mate ibiza coul come no where near me got his cat removed and it left me i removed mine and i was ever so slightly faster
i only changed cat an fmic and gained nearly 30 bhp if the cat did nothing it was all the fmic

cheers, good info!
out of interest, what boost does your hybrid run at?

as for the rest of you "decat" thread-jackers
if you remove the cat / soot trap, and thus remove a restriction / creating a free flowing exhaust, why wouldn't it increase bhp shrug:
if the exhaust gas can be expelled quicker, the turbo will spool up quicker and continue to do so a lot easier, so there will be an increase in bhp!!!

Around 1.8 bar, sometimes 2.0 bar which is around 26 to 28psi. Have seen over 2 bar of overboost but my car is constantly work in progress....

do we need cat for mot on tdi

 

[strugers1]

no cat needed for mot mate
i run 2.2bar overboost then 1.9constant till 4k then tails off to 1.7at redline
