I have an 02 WRX and thinking of upping the boost - is using a dawes device a dangerous option?

Anyone fitted / running one with good results?

Cheers

 

Nope, it's only as dangerous as the user... Get an accurate boost gauge and don't push the boost to ridiculous levels. Ask other 02 WRX owners what is a safe level. I ran one for around a year on a classic with no ill effects, but I was never tempted to raise the boost to fuel-cut levels.

 

I ran one on my 02 WRX upped the boost from 0.9 bar to 1.1, made a big difference. Ran it for 18months or so with no probs, you will hit fuel cut anymore than 1.15 ish though

 

cheers people - will buy one then. So 1.1bar is the safe limit then?

 

how much bhp increase will raising the boost to 1.1 give approx over standard boost?

 

are there any fitting guides around for this?

 

Not sure of the bhp increase, but even if you set it to standard boost, it will feel better because there is no spiking. I'm getting one soon. Where can you get original Dawes from?

 

I could not comment on what the safe limit was, only whatmy car would let me get away with.

BHP wise, not sure, just that you def noticed it

is it safer to run a better fuel pump with one of these?

 

can i use one of these to lower the boost,mine seems a tad high at 1.4 bar but nobody can find any fault with the thing

 

yes, that may well work

 

Cant do any harm, the standard pumps on these are weedy, and will be needed if you mod further

got one on my 03 had it on there almost from new, but people kept telling me dont run one on a new age, had not probs with mine, did have it set to 18 psi not sure what that is in bar but the engine light kept coming on, the chap from subaru asist told me to have it set for around 15-16 psi, so thats what i did and not probs at all and when mine went on the rollers i got 280 bhp and 250 torque not bad for a std car

 

1.4 is fine for an STi, if it ain't broke...

 

wrx or sti?

 

cheers mate but I need one for an 02 wrx - I'll check around the site

 

Just ordered the hybrid from 3bar racing. 26 quid delivered . Just hope I don't get 20 quids worth of customs charges.

Question for the guys with one: Their website states that it can run up to 15psi. I'm probably gonna need 17psi or 1.2bar. Have any of you had to adjust it to run more?
I did have one before on my Punto, and was running 21psi (1.4bar!! ). That didn't need adjusting.

 

I had one on a 94 UK car. Set it up using a boost gauge. Turned up up until I hit the fuel cut and then backed it off a bit.

Ran it like that for a couple of years with no problems at all. The only issue I had was having to adjust it when winter came as it would allow it to hit the fuel cut again.

 

Dawes on a newer car (99 onwards) are a bit obsolete tbh, your better off having a remap which is much safer

Whats a Dawes device?

 

Cheapo way of bleeding off boost from the actuator to allow the turbo to run high boost levels.

 

It should be able to adjust boost to 1.4 -1.5 bar. Mine went to 19 psi/1.3 bar when I was adjusting it and there where still a few turns left.

 

It is always better to run a higher-rated fuel pump and a parallel fuel rail mod on any Impreza, especially Classics...

 

L33 WRX, did you get one in the end.
I've got mine, but not got round to fitting it yet.
I've fitted them to other cars before, so shouldn't be a prob. But the only guid I can find on here is this one :http://stefanostadal.homedns.org/car_mods_engine.htm
and it doesn't work anymore.
