Assuming my guage is accurate my my95 WRX which is standard (apart
rom K&N induction kit and cold air box) peaks at just over 13PSI and holds 12.5PSI.Nice and healthy methinks.Whats yours boosting too.Full catless exhaust and Dawes to fit this weekend

 

Peaking 20, holding 18... Link...

Using defi - MY99, full decat ITG and Dawes.

No peak Just holds 1.1, about to go to 1.15 or 1.2 (on the gauge)

Actual boost shown on the select monitor was just over 15PSi held, I want more Bring on tomorrow

 

Peak/hold 19 PSI off MAP sensor output MY00 PPP Dawes.

 

peaks 1.1bar holds 1.0
S.Sport full system/ITG/Lamco boost gauge on an MY00 run on Super plus & Octane booster.

What the **** 19psi must feel like I don't know - think I need to get me one of these Dawes thingys. Feel very inadequate now!!!!!

 

Hmmmmm MY95 WRX peaking at 12psi and holding at 10.5psi

Car running like a bag of 5h1te at the moment, I think a trip to the scooby witch doctor for exocising.

 

My 95 WRX was maintaining the fueling up to 18.5 psi then the EGT started to creep up so I've called it a day there for the moment.

You need to beware that as far as fueling is concerned it is the mass air flow meter output that is the primary (perhaps only) reference for the ECU's fuel calculation during open loop.

That means that using a MBC/EBC and controlling to a manifold pressure of 18 psi may be safe one day and not another ! This is due to the actual air flow changing due to the ambient conditions and charge temperature.

I prefer to monitor Exhaust Gas Temp rather than lamda as it gives me a better indication of engine conditions.

 

1.3 peak, tend to get distracted by the fast moving scenery to check the level it holds at!

 

17 psi and all is well

 

John Banks Ihave read with interest your posts regarding the Dawes unfortunately some of the info goes right over my head!!Would i be right to say that hte best place to fit it in your opinion would be from the turbo nipple to the waste gate actuator,blanking off the original wastegate solenoid?Also what would you suggest to be a practical limit before fuel cut?I was hoping for 15-16psi Your comments would be appreciated. Thanks Michael

 

Sounds fine but depends on MY. On a MY99/00 can go up to 17 if you check fuelling etc.

 

Thanks John.Its a MY95 WRX.Keep the comparisons comming!

On my 95 WRX I hit the fuel cut at about 1.1 bar, someone elsewhere said the fuel cut on these cars is 15.5 PSI which sounds about right.

CC where did you put the sensor for your EGT? Is there a specific place on the manifold?

I used a fine wire K type thermocouple sensor in order to maintain quick response, I then drilled a little 1.5 mm hole in my turbo exhaust inlet housing. The metal here is about 6mm thick so no danger of weakening it ! Inserted the probe 8mm and hey presto !

Probe available from RS Components 15 pounds ish

Hi All -

Reaching and holding 16 PSI, MY94 STI 1. Manages 280BHP/269LB torque at these boost levels...... engine 'allegedly' standard.
