KCboy,

Hindi ko pa alam kung Tierra Pura or The Fort. Parang sobrang dehado ako sa The Fort kasi walang rear diff lock, eh.

Baka Tierra na lang.

na gawa ko na!!! ang dali lang pala lalo na pag mayroon kang super glue
but im not sold sa bolts maghahanap pa ako ng stainless na bolts he..he

kimpOy,
Ilan washers nilagay mo? 2pcs would be enough pero if you want pwedeng 4 hehehe :D

**kimpOy** · March 7th, 2003 12:19 PM

3 washers per bolt yellow,
gusto ko ng i testing sa expressway grrrrr

5 hours pa ako mag hihintay

Yellow::: bibilis pa kaya kapag 4 washers??? :?:

pajerokid,
Hmm di ko lang alam siguro from 3 washers di mo fefeel ang difference sa 4, dati kasi i tried 1 washer lang tapos 2 tapos 3, yung 1 washer wala masyadong improvement sa 2 washers meron na, sa 3 washers I can really feel the difference max natin siguro sa engines natin is 5 washers, that would be around +2.5 - 3.0 psi so if the stock is 10 nasa 13 na yan medyo mataas na baka di na kaya ng engines natin, kasi when you floor the accelerator it will spike to around 14 psi for a sec or so bago babalik sa 13psi.

kimpOy,
Paki post ng feed back, walang intercooler ang strada mo right? tell us if you can see any difference like pajerokid, at 3,000 rpm mas mabilis sya ngayon. :D

Very simple mod di ko lang alam ang wear and tear sa actuator can natin, but i think di masyado malaki ang difference, dinagdagan lang naman natin ang tension sa spring inside the can, para mas late mag open ang wastegate, and it helps sa lower rpm range, kasi when the turbo starts to spin medyo nag bubukas na din ang wastegate, now that the tension is higher the wastegate will start to open at a higher rpm range. Although its just my theory, but i think thats how it works. We could see with the improvement in power :D.

kailangan talaga ng boost gauge para alam mo kung anong boost yung kaya without going into some kind of limp mode.(safe mode).

yung lumang audi ko eh nagpalit ako ng stiffer wastegate spring, or pwede rin eh lagyan ng washers para mas stiffer sya. yung iba eh mbc(manual boost gauge), you can make your own boost gauge just search the web.

try this

or yung hallmans mbc

or the Greddy Profec-B Elec. Boost Controller merong hi/low setting

Yeah boost guage nga ang kailangan, I installed one before i tried putting washers on the actuator, just to know how much boost im getting.

i think a boost controller, even the manual one is still a better idea to boost up. adding tension to the wastegate actuator rod does help, and in many ways it reduces boost leak by making sure the wastegate is tightly shut but if your turbo is controlled electronically, it doesn't raise boost realistically because the ECU will let the boost out anyways.
