ATP PSI adjustment
Anyone messed about with the ATP PSI adjustment, and if so, any ballpark method to +/- PSI sort of reliably prior to taking out on road for testing? I am guessing 'actuator' and pop off need adjusting.... rough how much adjustment per PSI?
Thanks.

You have the little dashpot attached to the turbo - internal wastegate?
I deleted that thing - don't like it.
You need a controller or to swap parts to make a psi change.

I was under the impression that I could adjust the 'actuator' arm length, and maybe also need to bump up the blow off - since there is an adjustor knob on it also.
I don't think there is a dashpot on the turbo. Actuator, yes.

JC you could hook up a dial-a-boost kit...........77 bucks through Summit. It gives you a knob you twist to change boost. Just take small steps and watch the boost gauge  It just bleeds off pressure and fools your wastgate actuator into thinking its getting less pressure than it really is.....so wastegate stays shut longer and boost goes up  It just t's into the boost line to the actuator. Easy, just the way I like it 
BTW you'll be getting an e-mail shortly

Yes, I have messed with it. Bob was with me when we backed it down to minimum boost. I saw around 7 to 10 psi. It's not very accurate, and tends to fluctuate. I highly recommend you get an external waste gate.

How diferent is an external waste gate from an adjustable pop off valve?
How much more accurate and easy to use if any also?
Thanks

The pop off (blow off) is to release press from the airbox when you close the throttle.
The external wastegate is what controls the boost. It has a spring (like your cheesy deal) and you can hook up a controller to go above the sping psi

A good one is not going to be cheap - or even reasonable a lot of times. Beware of knockoffs as well..........

I would look into getting an evo9 or evo8 turbo. Excellent twin scroll turbos, almost instant boost on a 2 liter and there are evos in the 9s with the stock turbo (500 awhp).

I have a GT30 installed. Am looking for method to adjust the 'actuator', as I understand i can up the PSI +2 with it.

That is basically what I have(16G) - but a different housing. It is good for about 400HP......plenty above my goals, but not overly large. Why put on a turbo good for twice the target power?

By 16g, I assume you mean the evo3 turbo. The evo8 and 9 turbo is twin scroll and will not only spool faster, but make more power. Much better technology as well as longevity, that being said, most mitsubishi turbos are real reliable.

Ok, got the adjustment 'range' today from Harry for the 'actuator'. It appears about a 1 full turn towards the actuator body, for a 1-2 PSI change. I made the one turn and went from 6 to 7.
and I gotta tell you, even that little change was noticeable with the acceleration.
I am trying to summon my courage to bump it to 8. I do not want to blow anything up.

If you're happy with 6psi I would leave it there...it'll definately be easier on the engine, and safer as well. 6psi should be giving you 250 or so rwhp..........sounds like alot of fun to me  The guy I bought my kit from was running 8lbs of boost for a year on his stock motor with no isssues at all. Dave told me the engine will be fine as long as I don't go running wide open for miles on pump gas. I'm gonna run mine at 8  But I have thought about backing it down just to give me some extra protection and peace of mind If you don't need 8 I wouldn't do it. You can always gear the bike down a bit just like an NA bike if you need more acceleration.....you'll get more thrills without upping the boost and working the motor harder. My bikes up one tooth in back....I'm going to leave it there with 8lbs of boost, and if the powers too much I'm going to drop the boost abit instead of changing the gearing, it'll make life easier on the engine and accomplish the same thing as going to higher gearing, as far as making the bike more ridable on the street with a reasonable wheelbase and height And if I want more go I'm going to stick a 2 tooth larger on back lol. My boost is not going over 8lbs ever  From owning and knowing guys who owned other turbo bikes I've realized that the biggest problem with turbo bikes is not the machinery.............its the riders. Guys always want to push the bikes to the limit with boost. And what happens when you push the limit? You find the limit by breaking something. If you leave a machine alone, and let it run within its limits it'll run forever. Thats exactly how my turbo's going to get ran...within its limits

Bad,
Initially I had on 16/45 and then dropped to 43, 41, then changed back to 17 41. All of the gearing combo the bike just gets to speed to quick for shifting. OEM gears seem about perfect for me.
For the moment, I am even happier at 7! I will check it out for a bit and see.

I would be very careful going any higher.
Boost is like Crack. It's so tempting to turn it up just a little more, and so easy to justify; "I'm going into the mountains today, so I'll turn it up a little". You do that, then forget that you turned it up, come back to sea level, see some squid on a GSXR, and he's laughing at you as your bike is puking oil from the hole in the bottom of the crankcase.
Trust me, you will get used to 7 psi, or even 8. It will become your "normal" power. You WILL want more, but, don't even think about it until you've made major changed in the engine.
