What boost are you running on your GT3071R?

Sorry for the OT, but it seems to me that the power output of the 3071 isn't that far off the OE tubby bar for bar? But - the 3071 will support much higher boost levels. Would this mean that (actuator allowing), I could have close to stock power at say..0.5 bar?

The boost graphs show no fall off.

Being able to run stock power for street use is a big point for me, so I haven't dared put the 3071 on yet. But it seems I could give it a go now.. thanks.
Circumstance means I'm using my R to commute at the moment. Most of the time it doesn't go above 3Krpm. Its quite dark, damp and slippy on the roads at the moment but half throttle at 1.9Bar still overtakes cars in a safe manner. To be honest, the large swell of torque makes the car quite smooth to drive which is why I prefer a higher boost setting. Get your 3071 on, I bet you'll find it better than a T28 all round.Being able to run stock power for street use is a big point for me, so I haven't dared put the 3071 on yet.

My main point here is _if_ I get puplled over by the authorities and they decide to send me on their rolling road, I've got a LOT of problems if I'm pushing out 400+ horsies (not to mention a £20000 fine give or take. So it would mainly be driven at laughably low boost levels, but of course with the possibility of running it at full tilt, especially for track sessions.
May I ask what clamps you are using to keep the 1.9 bar inside the pipes?
Good point trond .. I've just damaged my turbo ( 3071) due to dodgy clamps .. I'm now facing a huge rebuild and labour cost to put my car back on the road .. I'm running 456 bhp at 1.8 peak dropping to 1.6 ... Once my turbo s rebuilt I will be replacing all hose clamps , but what to use ? May even double up at each connection

I think most people are using Mikalor or similar clamps.
You're best using a clamp that is near it's largest diameter,
ie say the pipe is 65mm in diameter and you have two clamps that are 59-68 and 63 -72 the better one to use would be the 59-68.
Make sure that you fit the clamp correctly (this sounds obvious but i've seen loads that haven't been done right) and that there isn't any oil/grease etc on the hose or pipe, contact cleaner is good for this....it's also useful to spray on the hose and clamp to allow them to slip over one another.
Make sure that the hose is the right diameter, again this sounds obvious but i've seen wrong size hose being used.

ive used the cheap clamps that come with the ebay kits with no probs and pressure tested the system to 3 bar aswell
best bet was degrease the inside of silicone and outside of ally pipe
then sligghtly ruff up the surface of the metal with some coarse sand paper then tighten clamps worked fine and saved paying a fortune for mikalors

As Stu said, equivalent to mikalor clamps from my local hydraulics shop. It sounds like you have some funky car laws in Scandinavia, could you run two boost levels? My 3071 hits 0.7Bar at around 2.8K so it is easily comparable to a standard boost T28.
Won't the Police just look at your turbo and realise the car isn't standard though?

Ash, you might be a superhero but when i've paid out for a 3071 i'm not going to chance it going pop cos a hose has popped off cos i've used a shitty clamp.
I went down to the local engineers suppliers and asked for hose clamps.....they turned out to be mikalors and were a couple of quid each! Much cheaper than from any performance supplier!
i actually had more grief with mikalors as they distorted the pipe and had some leak issues they can be very good maybe i should have done what steve did and used a sleeve inside them on one of the gtirs i had i used steel pipework onstead and they were fine on that and as u say use a clip thats near its top limit to help it keep its shape

they are a pain to get right sometimes and it's probibly the degreasing that's done the trick in the past.
I think it's the shaped part that's the problem, if the clamp is too big then that will be misshaped for the pipe if you see what i mean.
I've not tried the sleeve method as i've never needed to.

I could talk about this at length, but Norway is special when it comes to changing bits of your car. If it's a newer model, you're not really allowed to do anything. If it's older than 1989, you may alter ecu parameters, and other things regarding emissions (turbo, cams, turbo conversion, etc). If it's older than 1970, there aren't many rules, as you are submitted to rules that were made around 1945.
And it's not really the police that are the problem. I don't drive with much flamboyance on my way to work. However, the "automotive department" of the government are staging numerous controls along the roads. It does vary from region to region how "bad" they are, and where I live, they're pretty anal. The biggest problem is that the rules for modifying your car are open to interpretation, so other parts of the country may very well let you do a JDM engine swap in your Honda for that matter. That wouldn't fly here. The guy in charge actually _knows_ the rules, and his former job was crime scene investigation - road department. So he knows how bad things can get if a car is modified in a substandard way.
He also knows that if he allows modifications, and the car in question gets in an accident, it's his ass.
Add to that the fact that IF you manage to get through the red tape and get your modification approved, you may face up to £100 per horsepower in taxes. Oh joy.
The biggest irony is that the guy in charge of modifications here, runs a '69 escort with 900+ bhp. Road legal!
Aaaand, to answer your post - I'm currently running 0.6 bar on the PFC, but I've got three more settings up to 1.25 bar. So yes - I'm running different levels of boost. But they've recently passed rules about this as well, a couple of months ago. Great. But I'll just keep my head low, and hope for the best.
I've bought a bag of Mikalors, so I'll just have to clean it all off with brake cleaner or something first I guess. Thanks for the tip!
