only way to tell specifics is to have it with someone with det cans, mine on a hot day started to show signs of det at 1.19 even with my huge forge motorsport core so we pulled it back to run a solid 1.07 - 1.09 for the prolonged periods and then have left 1.2 for the odd spat if needed, not really needed though.

admitted it could be fuel or a variety of things that made the slight det but that was using 99 octane so I wouldn't push the stock turbo too far past 1.1 for prolonged periods

It used to be generally considered that safe was basically upto fuel cut at 1.2bar however that was 8-10 years ago and the majority of engines have many more miles on them now than they did back then.

Personally on a relatively standard car I would stick to 1.0-1.1 bar of pressure and take it easy if the weather gets very hot. An inlet air temperature gauge can help you see when its better conditions for hard driving.

yeah we run them at 1.1-1.2bar safely. The oem toyota specifications say factory specs is ok to 1.1bar and thats with the cat in etc.

Fuel cut on the st205 should be 1.35bar.

Never heard that before. Every ST205 that I have seen has cut at somewhere around 1.2 bar.

depends how accurate the gauge is your measuring it with. We always ran them at 1.2bar without issues or constant complaints of hitting fuel cut.

My standard UK ST205 only experienced fuel cut once and that was on a warm Goodwood track day. This was in the days before I had modified it in any way so didn't have a boost gauge. When I fitted a Greddy electronic boost gauge at a later date I could see the standard car was boosting to 1.2bar.

I subsequently discovered that this level of boost was higher than normal for an ST205 which I recall is set at 0.9bar on the actuator. After I joined the OC in 2000 and started poking around the engine bay I then found that Toyota had fitted a bleed valve to the actuator line! The car had only one previous owner before I acquired it, a company director who bought it under a PCP so I don't think he would have changed something on a new car.

I suspect as this was one of the first batch of 100 UK spec ST205's that Toyota raised the boost so that the dealer and press demonstrator cars had more impressive performance. This was (is?) quite common practice in the industry. There's a contemporary road test of an Aussie spec ST205 which revealed that the car wasn't completely standard :wink:

It looks like there's my answer from undagrwnd if his one works fine. Just a couple questions for you though if you read it. Does it still perform as well as a proper boost controller ie does the boost still rise as fast. And just out of curiosity how much difference does it feel like it makes when you up the boost and what other mods do you have?

Ritesh one works fine by what i've seen but the gain has to be significantly higher than mine does to acheive similar results although i'm not sure why if im honest

Post subject:  Re: Blitz dsbc type r
mine works fine yes. i got the gain on 28 and the boost ratio on 1.14 wich is 16.53psi (1.13bar)

short vid from 100km/u https://www.youtube.com/watch?v=xKMJparwxKc

boost rises very quick, and holds it quite well.

my mods are complete 3'' exhaust (+front pipe) , Berk Technology 3'' downpipe and Apexi Intake.
