Correct boost or not?

A while back now i fitted an Autometer boost gauge, one of the better models i could get. But not long after i fitted a boost controller to level out boost and to increase boost response, but when trialling the boost controller to see if it was all hooked up i turned the boost up, but notice that once ya turn the boost controller up the maximum the boost gauge would go to on both the stock gauge and the new gauge was about 8-9psi, if you turned the boost controller up further the gauges didn't read any higher... but ya can hear from the wastegate noise that it was making more boost but it was jsut bleeding with the wastegate and not actually getting more boost to the engine. I have heard from a few guys having a similar thing happen to them in that they can't seem to get more boost than that around 8-9 at the manifold... is there something that needs to be removed for you to be able to turn the boost up to around the 13-15psi mard... maybe do ya have to bypass a factory uni tthat stops you from boosting? Or is it because its only bleed valve and i need an electronic one to boost more? I need to work it out as once the new turbo goes in and stuff i am looking to turn the boost up and it aint looking like it will happen till i work it out. Thnx peoples. J.

I installed it all, but my mate has the same boost controller its just the gated single stage controller with in cabin switch, and i copied his exactly, i knew how to do it anyway but i jsut copied his and it his works fine however mine wont...? Not sure what the deal is, and he even watched his being fitted so when it came to mine we did it exactly the same so i dunno what it is. Like i fitted some for mates aswell and mine seems to be the only one that is odd? COuld it be a faulty unit?

"that y i use a DEFI for boost guage and HKS for controler...rather then Autometer and turbosmart....."

I take that your bagging my sh1t... sorry for not wasting my money on brands... Makes it easier when ya just buy a new turbo with a controlled boost wastegate actuator... don't need a boost controller. :)

Hey YBSLO4

I saw in your mods that your turbo is from ATP. I read last time that ATP have there own combination of housings and trims. They seem really know what they are doing and they offer different stages of turbo, they also do high flow to the standard turbo yeah??

Just want to ask about your T3/4, how is it? and what kws rating is are you getting? Was it expensive??

I have seen their white R33 around but haven't seen it being pushed.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.

      There is a warning that "this thread is super old" but they ignore that anyway...

      With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
