Im wondering how low a boost setting I can run with a power fc and its boost controller on a stock turbo series 1 R33 gts-t?

Basically i have my pod mounted where teh stock intercooler used to be behind the front bar and am hoping to be able to turn down the boost when theres a lot of water on the road to minimise sucking up water

any ideas how low a boost i could run on a stock turbo?

Dave you have identified a major drawback with relocating the air intake - especially if the stock under-guard shielding has been deleted. There is a lot of dust/dirt/mud/water going to be splashed around your intake, and winding back boost won't really reduce the type of catastrophic hydraulic engine failure that goes with poorly located/shielded intakes.

As a guide, check out some of the WRC cars and the off-road 4WD style snorkels they run in events like Rally Africa. Other rallies where they have only minor creek crossings, they seem to use well placed splash guards.

to answer your questrion thoguh, i'm pretty sure u can turn boost off (ie. no bleeding) this means u onl run the 7 psi or whatever the stock wastegate actuator runs. without modifying that i don't think u culd go any lower.

remember your right foot is always a good form of boost control as well, and is much easier to control.......

anyway i can adjust the stock wastegate to run lower boost?

my current setup is just using a bleed value and it never gets higher than 6psi

in the wet, i take it ez and use the right foot method anyhow, but was hoping i could use this as a back up method to shut down boost

my pod has a stone guard/shield between it and the wheel and since ive had the pod installed here, have jacked up the front end, so it doesnt ride so low, but it does have the inner guards removed

you wont be able to set boost lower the actuator spring level which is about 6psi on the r33 gtst. you could change the actuator rod spring so its less or you could adjust the length for a temporary work around

      He obviously had his reason for flipping you off. I wonder what it was...

      I have to agree like, yesterday, I was driving down the warringah freeway towards the bridge when this jackass driving a beaten up Honda civic cut me off so suddenly it made me almost yank the wheel to avoid him hitting my car. Honestly and he had the NERVE to flip me off (or some other gesture Idk). Im a calm guy, but really some people just dont deserve to have a license, let alone be allowed to drive on densely populated roads/highways. If youre gonna cut through lanes at least use the damn turn signal

      HPA do an interesting video on tuning, and Adrian shows on the dyno, moving from 10:1 to 12:1 (And I think even 13:1) and the power moves SFA. However, a couple of degrees of timing has a HUGE impact. Exhaust side of things will more be the length of the exhaust and how many bends and turns you have. The straighter you can keep it, the better. By a lot. Oh, and getting the diameter right. Bigger isn't always better. Going to big can actually lose you power.

      I have to say, most people I see on the road fit the bill of atrocious drivers. Whether they be cowboys in their dual cabs, bogans in the Commodores, or the soccer mums. Pretty much most people on the road put zero freaking thought into driving. Barely look further up the road then the end of their bonnet, and have never even thought about how catastrophically wrong shit can go, by doing what they all deem as normal driving. Especially their late braking, racing to stopped lights, and sitting half a foot off the bumper of the car in front at 110km/h. Wanna know what's even better? By the time their kids get to be old enough to learn to drive, they've already got in the back of their brain what is normal driving, how annoyed you're allowed to get at people etc, and then their parents who actually have zero freaking skill at driving (Even though they constantly say "I've been driving for 20 years and never had an accident!") teach the little twerps how to drive, or should I say, how to make a car move. Literally watched a parent teach their L Plater, on a 4 lane freeway, that you just slam the brakes on, and push your way over, even with a B Double bearing down on you, and that's how you should drive, rather then, just keep going to the next exit. Same shit happens all the time for side streets etc, watching numpties pull dumb shit turns pushing across 3 lanes of traffic, rather than just go up the road another 30 seconds, and take the next turn that'll get you to the same location... Oh, and the damn right lane bandits. Or the retards driving along with their headphones in, and can't hear the ambulance or fire truck right up their ass about to run them over...   Pretty much, people drive on the road, like ego centric f**ks, and don't actually think how dumb shit their driving is, how it could easily kill them or someone else in a split second, or at the very least, how they're driving is contributing to all the shit they're bitching about on the road, like shitty congestion!
